Abstract
In the case where former engine structure is held essentially constant, the automobile engine intake and exhaust structure of two stages of compression of the present invention, it is compared with four-stroke gasoline engine used at present, air-breathing is compressed into two strokes and acting two strokes of exhaust transfer to two cylinders to complete respectively.Piston in the two cylinders can be run to the top of cylinder, no residual gas, the gas in cylinder can be discharged completely, the piston phase difference in the two cylinders just realizes the combustion chamber volume of engine.
Description
Technical field
The present invention relates to a kind of intake and exhaust structures of four stroke automobile engines, increase hair using the method for two stages of compression
The quality of motivation sucking air.It avoids using turbocharged engine, the turbo lag of turbocharged engine when the slow-speed of revolution
Phenomenon keeps the output of engine more smooth；Bigger power can be exported under same displacement, while can take into account oil consumption.
Background technique
The automobile engine being currently known improves the air inflow of engine using supercharging technology is generallyd use, and raising is started
The power of machine, using turbocharging technology inevitably in low engine speeds, the phenomenon of turbocharger turbine sluggishness
Seriously, engine output ride comfort is poor.
Each cylinder of general four-stroke engine is involved in work by combustion, and design and manufacture are to fully consider each cylinder and song
The problems such as axis intensity cylinder radiates, causes that engine quality is larger, manufacture difficulty is big, is unfavorable for reducing cost.
Summary of the invention
Two strokes are compressed the object of the present invention is to provide a kind of air-breathing by engine and acting is vented two strokes point
The engine technology for not transferring to two cylinders to complete, and the acting of cylinder ratio used in air-breathing and compression travel and exhaust row
The cylinder of Cheng Suoyong is big, and big cylinder is pressed into lesser cylinder after air-breathing compression travel, by compressed gas, is equivalent to secondary
It is compressed, acting and instroke is carried out in small cylinder.
Piston in two cylinders can run to the top of cylinder and be completely exhausted out the gas in cylinder.The combustion of engine
Burn it is indoor reduce pinking without residual gas residue, phase when due to piston motion in the piston and small cylinder in big cylinder
Angular difference △ α, small cylinder piston reach when top is run down and concede space, make the big cylinder piston moved upwards will be in big cylinder
Compressed air be pressed into small cylinder, form combustion chamber.
In small engine load work, by adjusting the closing opportunity of big cylinder intake valve, change by compressed gas
Quality reduces distributive value, to realize fuel-economizing.
The mode of single axis realizes small displacement engine to improve economy in topology layout.Using the side of parallel double-crankshaft
The engine of formula realization more huge discharge.

Specific embodiment
The present invention uses parallel twin crankshaft engine structure, as shown in Figure 1
Exhaust valve assemblies (1), secondary inlet door component (2), level-one intake valve assembly (3), motor body (4), air-breathing compression
Piston component (5), air-breathing compression travel crankshaft (6), acting instroke crankshaft (7), acting exhaust pition component (8), air-breathing
Compress synchromesh gear (9), acting Exsufflation synchronization gear (10).
Engine acting unit of the present invention is same by air-breathing compression synchromesh gear (9) and acting Exsufflation synchronization gear (10)
The revolving speed for walking air-breathing compression travel crankshaft (6) and acting instroke crankshaft (7) makes air-breathing compression piston component (5) and does work
Exhaust pition component (8) differs a phase bit always.
It is of the present invention to use engine breathing structure (by taking parallel twin crankshaft engine structure as an example), as shown in Figure 2:
Level-one inlet channel (11), secondary inlet channel (12), exhaust passage (13), air-breathing compression cylinder (14), acting exhaust
Cylinder (15).
Air enters air-breathing compression cylinder (14) by level-one air intake duct (11) sucking air, in air-breathing compression cylinder (14)
After interior compression, by secondary inlet channel (12), compression enters acting exhaust cylinder (15) after burning again, passes through exhaust
Channel (13) discharge.
Inventive engine uses the structure of single axis, as shown in Figure 3:
Air-breathing compression piston component (5) and acting exhaust pition component (8) are connected on the crankshaft of an engine simultaneously, except song
The outer other parts of axis and the parallel twin crankshaft engine of present invention use are identical, on crankshaft two pitman shafts and crank spindle it
Between go into Space Angle, so that air-breathing compression piston component (5) and acting exhaust pition component (8) is differed a phase bit always, formation
The combustion chamber of engine.
Below by taking the engine operational cycle of parallel double-crankshaft as an example, illustrate the working cycles of inventive engine:
As shown in figure 4, acting exhaust cylinder (15) ignition-powering, acting exhaust pition component (8) move down, crank rotation is driven
Air-breathing compression piston component moves down sucking air and enters air-breathing compression cylinder.
As shown in figure 5, acting exhaust pition assembly operating, to lower dead center, air-breathing compression piston component continues to move down.
As shown in fig. 6, acting exhaust pition component moves up, exhaust valve assemblies are opened, by the High Temperature Gas after burning
Body discharge, air-breathing compress the lower dead center that piston component reaches cylinder, and suction stroke terminates.
As shown in fig. 7, acting piston component (8) reaches top dead centre, exhaust valve assemblies (1) are closed, air-breathing compression piston group
Part continues to move up, and the air in air-breathing compression cylinder (4) is by the first second compression.
As shown in figure 8, acting piston component (8) moves down, secondary inlet door component (2) is opened, and piston component is compressed in air inlet
(5) by compressed air second-compressed to acting exhaust cylinder (5), second-compressed stroke is completed when reaching top dead centre.
