Description

Mixer complete combustion device and control method for internal combustion engine

The present invention relates to a complete mixer of a mixer for heating air combusted with fuel in a combustion chamber of an internal combustion engine to an appropriate temperature and then supplying it to a combustion chamber of a carburetor or an engine. By supplying the air supplied to the cylinder of the mixer in a heated state, the mixer is burned in a heated and expanded state so that the mixer is completely burned in the internal combustion engine, so that the mixer for the internal combustion engine can improve the output of the internal combustion engine and reduce the exhaust gas. It relates to a combustion apparatus and a control method.

In general, an internal combustion engine that directly burns fuel in an engine generates power through inhalation, compression, expansion, and exhaust, and the internal combustion engine generates fuel in a combustion chamber consisting of a cylinder and a piston. Is a power generating device that generates power by directly rotating the crankshaft by the connecting rod and the crank mechanism by directly burning and transmitting the generated explosive energy to the piston.

The internal combustion engine that generates power through the stroke of intake, compression, expansion, and exhaust is largely mixed with liquid fuel such as gasoline in an appropriate ratio with air in a vaporizer to form a mixer, and the mixer is provided through an intake manifold. The carburetor type internal combustion engine that generates power by supplying it to the combustion chamber of the engine and compresses it, and injects liquid fuel directly into the combustion chamber of the engine, and removes foreign matter from the air cleaner through the intake manifold. It can be divided into direct injection type internal combustion engine which is supplied to and then compressed and exploded.

Such a carburetor internal combustion engine and a direct fuel injection internal combustion engine compress a mixer in which a liquid fuel and air are mixed at an appropriate ratio in a combustion chamber formed inside an engine, and then light the mixer to piston the explosion energy generated when the mixer is combusted. It receives this and rotates the crankshaft to gain power.

Since the internal combustion engine generates power by combustion of the mixer supplied to the combustion chamber of the engine, the exhaust gas of the combustion engine is discharged in the automobile. The exhaust gas contains a large amount of carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx), which are factors of air pollution. Such exhaust gas is generated by incomplete combustion of the mixer, so that the exhaust gas must be completely burned in order to reduce the exhaust gas and obtain high power with low fuel consumption.

That is, in an automobile engine, external air introduced through the air inlet installed in the front of the vehicle is purified by the air cleaner to form pure air, and the pure air is supplied to the intake manifold formed in the engine head or pure air. Is fed into the carburetor which is mixed with the fuel and then enters the combustion chamber of the engine.

The pure air supplied to the combustion chamber is mixed with fuel injected directly into the combustion chamber, or the piston is compressed into the combustion chamber while the pure air is supplied to the combustion chamber while being mixed with fuel at an appropriate ratio in the vaporizer before the air is supplied to the combustion chamber. Explosion energy is obtained by ignition, and is powered by the rotation of the crankshaft of the connecting rod and the crank mechanism connected to the piston.

However, during cold start with cold outside air, such as winter, the air supplied to the carburetor or engine intake manifold is low temperature, which is difficult to mix with fuel at an appropriate ratio. As the ratio increases, the fuel is not completely burned even if the mixer is exploded after compression in the combustion chamber, so that it is not possible to obtain a proper output, and harmful exhaust gas that escapes into the exhaust manifold without causing the mixer to burn completely causes air pollution. There is a problem that occurs.

The present invention is to solve the above problems, by supplying the pure air supplied to the intake manifold of the carburetor or the engine heated to an appropriate temperature, when mixed with fuel in the combustion chamber of the carburetor or engine at an appropriate ratio The purpose of the present invention is to provide a mixer-combusting mixer for an internal combustion engine that can increase the combustion efficiency of the mixer, improve the output of the internal combustion engine, and reduce the emission of harmful exhaust gases causing air pollution.

In addition, the pure air supplied to the combustion chamber of the engine during the cold start is mixed with the fuel at an appropriate ratio and then completely burned, and after the cold start, the pure water supplied to the carburetor or the intake manifold of the engine is reused. It is an object of the present invention to provide a method of completely burning a mixer for an internal combustion engine, by heating air to an appropriate temperature so that the mixer can be completely burned.

According to the technical idea of the present invention for achieving the above object, the carburetor 120 for mixing fuel and pure air is the engine 110 is connected to the intake manifold 112, and the carburetor 120 is pure air The air cleaner 130 for supplying the first, the first heating means 140 for heating the pure air supplied to the vaporizer 120 is installed in the air cleaner 130, and the first heating means 140 And a second that is formed to surround the air supply pipe 132 connecting the vaporizer 120 and heats the pure air supplied from the air cleaner 130 to the vaporizer 120 by using the coolant cooling the engine 110.

And a second heating means (150) for heating pure air supplied to the intake manifold (112) of the internal combustion engine.

Here, the first heating means 140, the blowing fan 142 for blowing pure air to the intake manifold 112 of the engine 110, and the intake manifold for the pure air blown from the blowing fan 142. Induction pipe 144 is installed in the interior of the air cleaner 130 to guide the fold 112 side, and is installed in the induction pipe 144 to heat the pure air when the pure air passes through the induction pipe 144 The first heat dissipation fin 148 is formed integrally with the heat generating element 146 and extends radially toward the inner diameter of the induction pipe 144 to transfer heat generated from the heat generating element 146. It is preferable to include.

In addition, the coolant induction pipe for guiding the high temperature coolant that cooled the engine to the radiator bypasses the air supply pipe connecting the air cleaner and the first heating means, thereby raising the temperature of pure air supplied from the air cleaner to the first heating means. When the temperature of the pure air heated up by the second heating means reaches the set temperature, the first heating means is stopped to reduce unnecessary power consumption.

Hereinafter, embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

1st Example

1 is a schematic view showing a first embodiment of a mixer complete combustion device for an internal combustion engine according to the present invention. Referring to the drawings, the complete combustion device for an internal combustion engine mixer according to the first embodiment of the present invention includes an engine 110 having a combustion chamber 116 exploding in a state where fuel and pure air are mixed, and the combustion chamber 116 is purified. An air cleaner 130 for supplying the supplied air, a vaporizer 120 for mixing liquid air, such as gasoline, with pure air supplied from the air cleaner 130, and a vaporizer installed in the air cleaner 130. The first heating means 140 for heating the pure air supplied to the 120, and the air supply pipe 132 for connecting the first heating means 140 and the vaporizer 120, the cooling water cooling the engine 110 Wrapped is composed of a second heating means 150 for heating the pure air supplied to the vaporizer 120.

The engine 110 is to obtain energy by exploding in a state of supplying the combustion chamber 116 formed inside the engine 110 in a state where pure air and fuel are mixed at an appropriate ratio, and the engine 110 is a cylinder. 118 is formed therein and the piston 111 is installed in the cylinder 118, so that the combustion chamber 116 formed between the cylinder 118 and the piston 111 in a proper ratio of the pure air and fuel mixture It is a device that obtains power by repeating the compression, explosion and exhaust stroke after intake of air.

That is, a cylinder 118 is formed in the engine 110 to linearly move the piston 111, and a connecting rod 115 and a crank shaft (not shown) are formed under the piston 111. This is organically linked. In addition, a combustion chamber 116 is formed in the upper portion of the cylinder 118 in which the piston 111 linearly moves, in which a mixer in which pure air and fuel are mixed at an appropriate ratio is combusted. An intake manifold 112 is formed.

On the opposite side of the intake manifold 112, an exhaust manifold 114 for exhausting the exhaust gas generated after the mixer is combusted in the combustion chamber 116 to the outside of the combustion chamber 116 is formed. Each of the fold 112 and the exhaust manifold 114 is provided with an intake valve 112a and an exhaust valve 114a.

In addition, when the mixer supplied to the combustion chamber 116 is compressed by the operation of the piston 111, a spark plug 113 for generating a spark in the mixer to generate instantaneous combustion (explosion) is installed at one side of the combustion chamber 116. .

Here, the operation for obtaining power in the internal combustion engine having the above structure will be described in the order of suction, compression, explosion, and exhaust stroke.

In the intake stroke, when the piston 111 descends from the top dead center to the bottom dead center with the intake valve 112a open and the exhaust valve 114a closed, the pressure is lower than atmospheric pressure due to the volume change in the cylinder 118. At the same time, a mixer in which pure air and fuel are mixed in the vaporizer 120 is sucked into the combustion chamber 116.

After the suction stroke is completed as described above, the compression stroke proceeds. The compression stroke causes both the intake valve 112a and the exhaust valve 114a to be closed and the piston 111 to rise to compress the mixer in the combustion chamber 116. do. At this time, the mixer in the combustion chamber 116 is a high temperature, high pressure state, after the suction stroke is completed, the suction mixer is compressed as the piston 111 rises in the state in which the suction and exhaust valves 112a and 114a are closed, Compression heat becomes high.

The explosive stroke, by the end of the compression stroke to generate an electric flame from the spark plug 113, the piston 111 is lowered by the pressure due to the combustion (explosion) of the mixer to rotate the crank shaft. That is, just before the compression stroke is completed (just before the piston reaches the top dead center for compression), when the mixer compressed by the electric spark of the spark plug 113 explodes, the piston 111 is pressed by the explosive force. Receives and descends to rotate the crankshaft through the connecting rod 115.

After the explosion stroke is completed as described above, the exhaust stroke proceeds. The exhaust stroke includes the intake valve 112a, the exhaust valve 114a, and the piston 111 rising to exhaust gas from the exhaust manifold 114. Is discharged through). That is, when the piston 111 is raised (upper dead center) while the intake valve 112a is closed and the exhaust valve 114a is open, the burned gas is exhausted from the engine 110 through the exhaust manifold 114. It is discharged to the outside.

In the combustion chamber 116 of the engine 110 that generates power through intake, compression, explosion, and exhaust stroke as described above, a mixer in which fuel and pure air are mixed at an appropriate ratio is provided through the intake manifold 112. The intake manifold 112 is connected to the vaporizer 120 so that the air inlet manifold 112 is supplied to one side of the vaporizer 120 to purify the outside air to supply pure air to the vaporizer 120. Is installed.

The carburetor 120 mixes the necessary pure air and fuel in an appropriate ratio according to the operating state of the engine 110, and makes the fuel to atomize and make a good condition for vaporization and supply it to the combustion chamber 116 of the engine 110. In particular, in the first embodiment, the first heating means 140 for heating the pure air is installed inside the air cleaner 130 for supplying the pure air, and the stroke of suction, compression, explosion, and exhaust is repeated to generate a high temperature. The second heating means 150 for cooling the coolant having cooled the engine 110 is installed in the air supply pipe 132 connecting the first heating means 140 and the vaporizer 120.

In other words, the first heating means 140 is installed inside the air cleaner 130 so that the pure air purified by the air cleaner 130 is heated to a predetermined temperature before being supplied to the vaporizer 120. In order to supply to the 120, the first heating means 140 is a blowing fan 142 for blowing pure air to the intake manifold 112 of the engine 110, and the air blown from the blowing fan 142 Induction pipe 144 is installed in the interior of the air cleaner 130 to guide the pure air to the intake manifold 112 side, and the inside of the induction pipe 144, the pure air is to pass through the induction pipe 144 The first heating element 146 for heating the pure air and the first heat generating element 146 integrally formed with the heating element 146 and extending radially toward the inner diameter of the induction pipe 144 to transfer heat generated from the heating element 146. It is composed of a heat radiation fin (148).

In addition, the second heating means 150, the second heat dissipation fin 152 and the second heat dissipation fin 152 which are formed integrally with the inner diameter of the air supply pipe 132 and extend radially toward the center of the air supply pipe 132, The air supply pipe 132 is formed to penetrate the cooling water induction pipe 160 through which the cooling water for cooling the engine 110 flows.

That is, as shown in FIG. 3, the first heating means 140 and the second heating means 150 are installed on a flow path for supplying pure air to the intake manifold 112 of the engine 110. The first heating means 140 is installed on the flow path connecting the vaporizer 120 and the air cleaner 130, the first heating means 140 is installed in the air cleaner 130, the engine 110 Heated to a certain temperature while passing through the heat generating element 146 and the first heat dissipation fin 148 installed in the induction pipe 144 before the external air is supplied to the vaporizer 120 in a state purified from the air cleaner 130 Furnace is supplied to the vaporizer 120.

In this way, the pure air supplied to the vaporizer 120 at a temperature raised to a predetermined temperature is mixed with the fuel in the vaporizer 120 in an appropriate ratio to form a mixer, the mixer of the vaporizer 120 is an intake manifold of the engine 110 Since it is supplied to the combustion chamber 116 through the fold 112 and is compressed and exploded by the piston 111, it is possible to completely burn the mixer of the combustion chamber 116 to obtain a high output with low fuel consumption, and the mixer is completely burned. It is possible to reduce the exhaust gas.

That is, the pure air supplied from the air cleaner 130 to the vaporizer 120 is introduced into the vaporizer 120 in a state of being heated up by the first heating means 140, and is introduced into the vaporizer 120 in the state of being heated up. Since pure air has a high molecular activity (especially oxygen), it is possible to form a mixer for obtaining high-efficiency explosion energy with a smaller amount of fuel than when the fuel is mixed with low-temperature pure air.

In particular, when the engine 110 such as cold start is not preheated and external cool air is directly supplied to the vaporizer 120, fuel and pure air are not mixed in an appropriate ratio, and the ratio of fuel is greater than that of pure air. By mixing, since the mixer remains in the combustion chamber 116 without being completely burned, the output is low compared to the consumption of fuel and the emission of the exhaust gas is increased, but the temperature of the pure air inside the air cleaner 130 is increased. By providing the first heating means 140, not only high power can be obtained with low fuel consumption, but also exhaust gas can be reduced.

Meanwhile, as described above, in the state where the engine 110 is preheated to some extent after the cold start, pure air supplied from the air cleaner 130 to the first heating means 140 may be reused by reusing the cooling water cooling the engine 110. The second heating means 150 for heating is installed in the air supply pipe 132 connecting the first heating means 140 and the vaporizer 120.

The second heating means 150 is installed in the air supply pipe 132 connecting the first heating means 140 and the vaporizer 120, by using the waste heat that cooled the engine 110 after cold start (Air Cleaner ( In 130, the pure air flowing into the vaporizer 120 is heated to a predetermined temperature and supplied.

To this end, the second heating means 150 is an air supply pipe 132 for connecting the air cleaner 130 and the vaporizer 120 to the coolant induction pipe 160 for guiding the coolant cooling the engine to the radiator 180. By bypassing the high temperature coolant to increase the temperature of the pure air supplied from the air cleaner 130 to the vaporizer 120.

That is, the air supply pipe 132 is installed through the coolant induction pipe 160 through which the high temperature coolant flows, and the second heat dissipation fin 152 is formed in the inner diameter of the air supply pipe 132 that has passed through the coolant induction pipe 160. By being formed, the high temperature of the cooling water is transferred to the air supply pipe 132 to raise the pure air passing through the second heat dissipation fins 152 to a predetermined temperature.

On the other hand, when the pure air supplied from the air cleaner 130 to the vaporizer 120 by the second heating means 150 is supplied in a state where the temperature is raised to a predetermined temperature, the heating element 146 of the first heating means 140 is It is possible to reduce the power consumption for operation.

To this end, each of the first heating means 140 and the second heating means 150 is provided with a first temperature sensor 149 and a second temperature sensor 154 for measuring the temperature of the pure air, The first temperature sensor 149 and the second temperature sensor 154 are electrically connected to an ECU (Electronic Control Unit) that controls the ignition timing and fuel injection of the combustion chamber 116.

That is, the first temperature sensor 149 is installed inside the induction pipe 144 in which the first heating means 140 is installed to measure the temperature of the pure air heated by the heating element 146. The second temperature sensor 154 is installed in the air supply pipe 132 in which the second heating means 150 is installed, and measures the temperature of the pure air passing through the second heat dissipation fin 152 to transmit to the ECU.

Thus, the temperature of the pure air passed through the first heating means 140 and the second heating means 150 measured by the first temperature sensor 149 and the second temperature sensor 154. When the temperature of the pure air passing through the second heating means 150 reaches the set temperature compared with the preset temperature input to the ECU, the operation of the first heating means 140 may be stopped to reduce unnecessary power consumption.

In other words, when the engine 110 is not preheated, the first temperature sensor 149 may measure the temperature of the pure air supplied from the first heating means 140 to the vaporizer 120. When the temperature of the pure air is measured and lower than the set temperature (for example, the set temperature is 85 ± 5 ° C.), the ECU operates the heating element 146 installed in the first heating means 140 to raise the pure air. It is supplied to the carburetor 120 in the state.

In addition, when the engine 110 is preheated to some extent, a high temperature is generated in the engine 110, and the coolant for cooling the engine 110 is generated because the high temperature of the engine 110 causes an adverse effect on the engine efficiency. After flowing to the water jacket (not shown) of the engine to cool the engine 110 is led to the radiator 180.

At this time, the coolant induction pipe 160 for guiding the high temperature coolant cooling the engine 110 to the radiator 180 bypasses the air supply pipe 132 connecting the air cleaner 130 and the first heating means 140. As a result, the pure air supplied from the air cleaner 130 to the first heating means 140 is heated up. When the temperature of the pure air heated up in the second heating means 150 reaches the set temperature, the first heating means is heated. Stopping 140 reduces unnecessary power consumption.

2nd Example

On the other hand, in some cases, an engine having a structure different from that of the engine described in the first embodiment may also be implemented with a mixer-combustor complete combustion apparatus for an internal combustion engine according to the present invention. This will be described based on FIG. 2.

The engine structure of the second embodiment described below is a structure in which pure air and fuel are directly injected into the combustion chamber 116 of the engine 110 to mix pure air and fuel in the combustion chamber 116. Although different from the engine structure, since pure air and fuel are supplied to and mixed with the combustion chamber 116, the output is obtained in the same stroke. Therefore, in the second embodiment described later, the first heating means 140 and the second heating means 150 The detailed description and operation after the fuel and the pure air are supplied to the combustion chamber 116 will be omitted.

2 is a schematic view showing a second embodiment of the mixer-combustion apparatus for an internal combustion engine according to the present invention. Referring to the drawings, the engine 110 injects the fuel supplied from the fuel tank 170 to one side of the combustion chamber 170 to inject the fuel directly into the combustion chamber 116 to the combustion chamber 116. ) Is installed.

The injector 117 is an injection nozzle with a solenoid valve for injecting fuel by the injection signal sent from the ECU. The injector 117 opens the injection outlet when the injector 117 operates and injects fuel directly into the combustion chamber 116. In addition, the intake manifold 112 is connected to an air cleaner 130 that purifies the air outside the engine 110 and supplies it to the combustion chamber 116. A first heating means is formed inside the air cleaner 130. 140 is installed, and the second heating means 150 is installed in the air supply pipe 132 connecting the intake manifold 112 and the air cleaner 130.

The first heating means 140 has the same structure as described in the first embodiment, but the fuel and the pure air are titrated between the first heating means 140 and the intake manifold 112 installed inside the air cleaner 130. There is no vaporizer 120 for mixing in proportion and pure air heated in the first heating means 140 is directly supplied to the combustion chamber through the intake manifold 112.

In other words, the first heating means 140 is installed inside the air cleaner 130 and the pure air purified at the air cleaner 130 is purified at a predetermined temperature before being supplied to the combustion chamber through the intake manifold 112. In order to supply the air in a state of raising the temperature, the first heating means is a blowing fan 142 for blowing pure air to the intake manifold 112 of the engine 110, and the air blown in the blowing fan 142 Induction pipe 144 is installed in the interior of the air cleaner 130 to guide the pure air to the intake manifold 112 side, and the inside of the induction pipe 144, the pure air is to pass through the induction pipe 144 The first heating element 146 for heating the pure air and the first heat generating element 146 integrally formed with the heating element 146 and extending radially toward the inner diameter of the induction pipe 144 to transfer heat generated from the heating element 146. It is composed of a heat radiation fin 148, the inside of the induction pipe 144 foot A first temperature sensor 149 is installed for measuring the temperature of pure air heated by the thermal element 146.

In addition, the second heating means 150, the second heat dissipation fin 152 and the second heat dissipation fin 152 which are formed integrally with the inner diameter of the air supply pipe 132 and extend radially toward the center of the air supply pipe 132, The air supply pipe 132 is formed to pass through the coolant induction pipe 160 through which the coolant that has cooled the engine 110 flows, and the high temperature coolant flowing through the coolant induction pipe 160 inside the supply pipe 132. The second temperature sensor 154 for measuring the temperature of the pure air heated by the is installed.

As such, the pure air supplied to the intake manifold 112 in a state of being heated by the first heating means 140 to the second heating means 150 may be directly injected into the combustion chamber 116 by the injector 117. Since the mixture is mixed at an appropriate ratio to form a mixer, it is self-ignited and exploded by the compression of the piston 111, so that the mixer of the combustion chamber 116 can be completely burned, and high power can be obtained with low fuel consumption, and the mixer is completely burned. In addition to reducing the exhaust gas, when the temperature of the pure air heated by the second heating means 150 reaches a set temperature, the first heating means 140 may be stopped to reduce unnecessary power consumption.

On the other hand, the control method of the mixer-combustion apparatus for internal combustion engines which has the above structure is demonstrated based on FIG. Referring to the drawings, the control method of the internal combustion engine mixer complete combustion apparatus according to the present invention measures the temperature of the pure air supplied from the air cleaner 130 to the intake manifold 112 of the engine 110 at the time of cold start The initial temperature measurement step (S110) is performed.

In other words, when the cooling start is started, the ECU operates the fuel tank 170 and the air cleaner 130, and thus the fuel and the pure air supplied from the fuel tank 170 and the air cleaner 130 are adjusted at an appropriate ratio. The mixture is mixed in the vaporizer 120 or fed to the combustion chamber 116 so as to be mixed. At this time, the initial temperature measurement measured by the first temperature sensor 149 installed in the first heating means 140 the temperature of the pure air supplied from the air cleaner 130 to the intake manifold 112 of the engine 120 Step S110 is performed.

When the measured temperature is lower than the set temperature after comparing the temperature of the pure air with the set temperature after the initial temperature measuring step (S110), the air cleaner 130 is supplied to the intake manifold 112 of the engine 110. The first heating step (S120) for supplying the pure air in a state where the first air heating means 140 is heated to the elevated temperature is carried out.

After the first temperature increase step S120 is performed as described above, the engine 110 obtains power by repeating the intake, compression, explosion, and exhaust strokes. Will have

In this state, the coolant for cooling the high-temperature engine 110 flows through the water jacket of the engine 110 to the radiator 180, and the first heating is performed in the air cleaner 130 by the second heating means 150. A second temperature increase step S130 is performed to increase the temperature of the pure air supplied to the means 140.

Accordingly, since the pure air supplied to the intake manifold 112 through the first temperature raising step S120 and the second temperature rising step S130 has high molecular activity, it is less than when the fuel is mixed with the low temperature pure air. The amount of fuel alone can form a mixer for obtaining high-efficiency explosion energy, from which high power can be obtained with low fuel consumption, and exhaust gas can be reduced by completely burning the mixer.

In addition, the temperature rising temperature of the second temperature sensor 154 installed in the second heating means 150 measures the temperature of the pure air heated by the cooling water cooling the engine 110 after the second temperature rising step (S130). The measuring step S140 is performed.

After the step of measuring the temperature rise temperature (S140) as described above, the temperature of the pure air measured by the second temperature sensor 154 installed in the second heating means 150 is compared with the preset temperature previously input to the ECU to heat the second. When the temperature of the pure air passing through the means 150 reaches the set temperature, the first temperature increase step S150 is performed to stop the first temperature increase step S120, thereby stopping the operation of the first heating means 140. Unnecessary power consumption can be reduced.

On the other hand, the present invention is not limited only to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, it should be seen that such modifications and variations are included in the technical idea of the present invention. do.

For example, although the above description has described an internal combustion engine installed in an automobile, it may be applicable to all internal combustion engines installed in facilities requiring power, such as a ship or a power plant.
