UNITED STATES PATENT OFFICE.
INTERNAL-COMBUSTION ENGINE.
Application filed December 15, 1924. Serial No. 755,813.
This invention relates to internal combustion engines, and my improvements are directed to means for gasifying the heavier hydrocarbons, such for example as furnace oil, by bringing such fuel into the vicinity of the maximum heat zones of the engine, to be gasified thereat, the gases then being conveyed to a mixing chamber where they mingle with a supply of air, and then the mixt-ure is admitted to the intake manifold for aspiration into the cylinders.
The air supplied to the mixing chamber is first heated by being passed through a jacketed space about the cylinder heads, and carries with it a proportion of moisture which is generated into steam in such passage.
Some of the mixture becomes comprcs fll in spark plug chambers which communicate as by hollow n'ecks with the combustion chambers of the respective cylinders, these spark plug chambers forming the hottest zones of the engine. wherein is created the initial combustion of fuel mixture.
Other features and advantages of my invention will hereinafter appear.
In the drawings:
Figure 1 is a side elevation of an automobile engine to which my improvements are applied.
Fig. 2 is an enlarged sectional view on the line 2-2 of Fig. 1, showing a portion of a cylinder head to which is attached my improved fuel gasifying means, the air and gas mixing chamber also being shown, and means communicating therefrom to the intake manifold.
Fig. 3 is a top plan View of the mixing chamber, and
I Fig. 4 is an enlarged sectional view on the line H of Fig. 1. r
The four-cylinder engine here shown by way of example is provided with an intake manifold 1. which is in communication, by a pipe 2, with a cylindrical mixing chamber 3 that is disposed above the engine, extend ing lengthwise thereof.
The cylinder heads 4. are each shown as equipped with a. spark plug chamber 5 in the form of a hollow bulb, and provided with a neck portion 6 by which it is screwed into the usual spark plug orifice 7. The bulbs 5, which each contain aseries of heat radiating fins 8, also each have a horizontally disposed, internally threaded sleeve 9, for the reception of a spark plug 10, whose sparkling points are thus brought into the centre of the bulb. It will be appreciated that as the gaseous mixture is fired within the bulbs 5 the heat therein becomes very intense and has the effect of preventing the formation of carbonaceous deposits.
Exteriorly of the hot bulbs I provide chambers wherein liquid fuel may become gasiiied under the influence of the heat they supply. Thus I affix a short cylinder 11 oh top of each bulb 5, the upper surface of the bulb forming the base of the gasifying chamber. These cylinders 11 are then fitted to other short cylinders 12 that depend from and communicate with a mixing chamber, here shown as a horizontal cylinder 3, which is closed at both ends.
A fuel pipe 13 extends through the cylinders 11, and within each cylinder is provided with one or more fuel exit openings 14, to permit liquid fuel to'drop therefrom on to the top of bulb 5, thereby becoming gasified, and the gaseous fuel then ascending into the mixing chamber 3.
The pipe 13 leads from a vacuum tank or other receptacle 15, here shown as attached to the dash, but which may have any other location. Valve 16 and control means 17 are also indicated.
In addition, I provide a tank 18 containing gasolene or other priming fuel, and a pipe 19 leading therefrom to the intake manifold,
a valve 20 and control means 21 being indi-' cated in connection therewith. The use of the priming fluld 1S necessary in starting the engine from cold, because the heavier oil requires to be gasified by the engine heat before it will function as fuel.
The air supplied to the mixing chamber is first heated by bringing it in contact with the engine. In the present example I have shown the air pipe 22 as leading to the usual water jacket 23 (which contains no cooling water) and I have shown a pipe 24- as leading from the water jacket to a manifold 25 which supplies the mixing chamber at 26, 26. Under the aspiratory operation of the engine the pull from the mixing chamber is through pipe 2, the intake manifold 1, and thence into the cylinders.
In order that some moisture may pass with the air into the mixing chamber I have shown a water tank 27 as taking the place of the usual radiator, and a spout 28 extends therefrom toward a flared inlet 29 for pipe 22. Normally the spout 28 is held closed by a spring valve 30, but when the engine is v in operation the rush of air into inlet 29 will open the valve and draw a limited quantity of. water into pipe 22. This water in passing through the engine jacket will be converted into steam and as such will aid in the production of a highly efiicient gaseous mixture of fuel, air and steam. Furthermore, the air entering the jacket 23 will by heat exchange serve to cool the cylinders, while itself becoming raised in temperature, whereby it is better enabled to blend with the gaseous fuel in mixing chamber 3 for the formation of an efficient combustible mixture.
The intake ports 31 for the respective cylinders, to which fuel mixture is directed by the manifold 1, are here shown as controlled by a slide 32 that normally covers said ports. The slide 32, which is here shown is connected by a link 33 with an accelerator pedal 34,
is provided with apertures 35 that may be caused to register with the ports 31 in greater or less degree accordingto the extend of the movement imparted to the slide by the accelerator action. In other words, the slide 32 is intended to function in the manner of a throttle to thereby control the quantity of fuel mixture admitted to the cylinders.
Compression holding means, as valves 36, may be employed, and the engine exhaust means may also be of usual character.
Variations within the spirit and scope of my invention are equally comprehended by the foregoing disclosure.
