Abstract
This invention relates to an expansion piston diesel including a body, a cylinder on the body, a crank guide and an inlet and a discharge pipe, among which expansion cylinder is set on the body, the connecting rod of the expansion cylinder is on the same crank with that of the cylinder, the discharge pipe of the cylinder is the inlet of the expansion cylinder which general volume is 1.1-3.5 times that of the cylinder.
Description
Technical field
The present invention relates to a kind of reexpansion internal-combustion piston engine, belong to the combustion engine technical field.
Background technique
For a long time, there is such problem in four-stroke internal combustion engine always, promptly in the expansion space stroke stage, the abundant work done that also is not able to do in time of the expanding gas of high temperature, high pressure, just squeezed, outside exhaust valve is discharged cylinder, cause the lot of energy loss by the piston in next exhaust stroke stage.In " extraordinary engine principles and structure " book of publishing Shanghai science tech publishing house in September, 1998, from the 7RND90 diesel engine be example thermal equilibrium analysis heat balance diagram and
Can see in the flow graph that the fuel heat of exhaust loss reaches 26.05%, exhaust loss accounts for fuel
10.19% of value, and mention in the literary composition, the heat quality that the higher temperature exhaust is taken away is also higher, is valuable, rational so make full use of exhaust complementary energy.
Summary of the invention
Technical problem to be solved by this invention provides a kind of reexpansion internal-combustion piston engine that can utilize the high energy saving of the thermal efficiency of exhaust complementary energy.
It is as follows to solve the problems of the technologies described above the technological scheme that is adopted:
A kind of reexpansion internal-combustion piston engine, it is the improvement on former internal-combustion engine basis, it comprises body, is located at cylinder, connecting rod and air inlet and exhaust piper on the body, said body is provided with the reexpansion cylinder, the connecting rod of reexpansion cylinder and air cylinder connecting rod be bent axle altogether, the suction tude condominium of the outlet pipe of cylinder and reexpansion cylinder, the total measurement (volume) of reexpansion cylinder are 1.1-3.5 times of cylinder total volume.
Above-mentioned reexpansion internal-combustion piston engine, said reexpansion cylinder be provided with two suction tude of two suction tude each with the outlet pipe condominium of a cylinder.
Above-mentioned reexpansion internal-combustion piston engine, said reexpansion cylinder is provided with an outlet pipe.
Above-mentioned reexpansion internal-combustion piston engine, said reexpansion cylinder is provided with two outlet pipes.
Be example with two cylinders and this machine below, its order of work be listed as follows with reexpansion cylinder formation of two intake valves, an exhaust valve:
| Crank angle | Cylinder I | The reexpansion cylinder | Cylinder I I | |||||||
| Stroke | Intake valve | Exhaust valve | Stroke | Intake valve I | Exhaust valve | Intake valve II | Exhaust valve | Intake valve | Stroke | |
| 0°-180° | Expansion space stroke | Close | Close | Exhaust stroke | Close | Open | Close | Close | Open | Intake stroke |
| 180°-360° | Exhaust stroke | Close | Open | Expansion space stroke | Open | Close | Close | Close | Close | Compression stroke |
| 360°-540° | Intake stroke | Open | Close | Exhaust stroke | Close | Open | Close | Close | Close | Expansion space stroke |
| 540°-720° | Compression stroke | Close | Close | Expansion space stroke | Close | Close | Open | Open | Close | Exhaust stroke |
By in the table as can be seen, bent axle whenever takes two turns, two each works done of cylinder once, then twice of the work done of reexpansion cylinder.This is because the reexpansion cylinder of this machine has only air inlet expansion space stroke and exhaust stroke, and the gas that the reexpansion cylinder is advanced is the gas of the exhaust stroke stage discharge of cylinder.Though so this machine can adopt the structural type of a reexpansion cylinder of a cylinder arrangement, use uneconomically in four stroke engine, because such structural type, crank takes two turns the work done of reexpansion cylinder once.If reexpansion cylinder of per two cylinder arrangement can be realized this machine like this in running, bent axle whenever turns around, and then work done is once for the reexpansion cylinder.
This machine is because of being provided with the reexpansion cylinder, its body should be on the basis of former engine body, the corresponding physical dimension that changes, in addition, according to the reexpansion cylinder concrete condition of an exhaust valve or two exhaust valves is set, its distribution device of supplying with in the system also should be changed on the basis of joining 2 mechanism of qi structures of former motor accordingly.Other are identical with former motor or similar as connecting rod, lubricating system, cooling system, starting arrangement etc.
Reexpansion internal-combustion piston engine provided by the present invention, because of it has adopted the reexpansion cylinder, the waste gas after burning that former cylinder was discharged in the exhaust stroke stage is carried out the reexpansion work done, so thermal efficiency height, the energy saving of this machine, noise is little.This reexpansion internal-combustion piston engine is the power plant of automobile, tractor, boats and ships etc.
Description of drawings
Fig. 1 is a kind of embodiment's sketch of this reexpansion internal-combustion piston engine.
Embodiment
The invention will be further described below in conjunction with embodiment:
Referring to accompanying drawing, reexpansion internal-combustion piston engine provided by the present invention comprises body, is located at cylinder, connecting rod and air inlet and exhaust piper on the body, said body 2 is provided with reexpansion cylinder 7, the connecting rod 9 of reexpansion cylinder 7 is total to bent axle 1 with cylinder 4 connecting rods 3, the suction tude condominium 6 of the outlet pipe of cylinder 4 and reexpansion cylinder 7, the total measurement (volume) of reexpansion cylinder 7 are 1.1-3.5 times of cylinder 4 total measurement (volume)s.The reexpansion cylinder of big volume not only helps reducing the exhaust resistance of cylinder 4, and the abundant expansion working of waste gas after burning that helps cylinder to discharge.
Shown in the figure, reexpansion cylinder 7 is provided with two suction tude, two suction tude each with the outlet pipe condominium of a cylinder 4.Reexpansion cylinder 7 can be provided with an outlet pipe 8, also can be provided with two outlet pipes 8.Reexpansion cylinder 7 should be established independently vent systems.
Shown in the figure, the air inlet of reexpansion cylinder 7 can with the shared exhaust valve 5 of the exhaust of cylinder 4.In addition, the intake stroke of reexpansion cylinder 7 should keep synchronously with cylinder 4 exhaust advancement amounts, and promptly the piston of reexpansion cylinder 7 should arrive top dead center when the exhaust valve of cylinder 4 is opened.
