Abstract
The invention discloses a kind of size cylinder internal-combustion engine, structure includes big cylinder body, small cylinder body, piston, connecting rod, cylinder cap, bent axle, main shaft, pressure valve, snifting valve and spark plug；The diameter of the big cylinder body than the small cylinder body diameter more greatly；Piston is equipped in the big cylinder body and the small cylinder body；The lower section of the piston is equipped with connecting rod；The top of the big cylinder body and the small cylinder body is equipped with cylinder cap；Combustion chamber is equipped in the cylinder cap；Pressure valve is equipped between the small cylinder body and the combustion chamber；Snifting valve is equipped between the big cylinder body and the combustion chamber；Spark plug is equipped in the combustion chamber；The lower end connection bent axle of the connecting rod；The bent axle and the main shaft are coaxially arranged；The side of the small cylinder body is equipped with inlet valve；Intake valve is equipped in the inlet valve；The side of the big cylinder body is equipped with exhaust valve；Air bleeding valve is equipped in the exhaust valve.The beneficial effects of the invention are as follows：Because the diameter of big cylinder body is more than the diameter of the small cylinder body, the high-pressure gas in combustion chamber is injected to the ratio expanded in big cylinder body and is greater than in the small cylinder body to the compression ratio of live gas, so the efficiency of the present invention is higher than traditional internal combustion engine.
Description
Technical field
The present invention relates to a kind of internal combustion engine more particularly to a kind of size cylinder internal-combustion engines.
Background technology
The cylinder of traditional internal combustion engine only has one kind, that is to say, that internal combustion engine air-breathing, compression, acting and exhaust are all same
It is completed in one cylinder, the tail gas of such internal combustion engine, which also has in very high temperature and pressure, to be utilized, thus efficiency is low.
Invention content
Problem to be solved by this invention is to provide a kind of size cylinder internal-combustion engine, efficient, can will be more than tail gas
Pressure is using completely.
In order to solve problem above, technical scheme is as follows：
A kind of size cylinder internal-combustion engine, structure include big cylinder body, small cylinder body, piston, connecting rod, cylinder cap, bent axle, main shaft, calm the anger
Valve, snifting valve and spark plug；The diameter of the big cylinder body than the small cylinder body diameter more greatly；The big cylinder body and the small cylinder
Piston is equipped in body；The lower section of the piston is equipped with connecting rod；The top of the big cylinder body and the small cylinder body is equipped with cylinder cap；It is described
Combustion chamber is equipped in cylinder cap；Pressure valve is equipped between the small cylinder body and the combustion chamber；The big cylinder body and the combustion chamber
Between be equipped with snifting valve；Spark plug is equipped in the combustion chamber；The lower end connection bent axle of the connecting rod；The bent axle and the master
Axis is coaxially arranged；The side of the small cylinder body is equipped with inlet valve；Intake valve is equipped in the inlet valve；The side of the big cylinder body
Equipped with exhaust valve；Air bleeding valve is equipped in the exhaust valve.
The beneficial effects of the invention are as follows：Because the diameter of big cylinder body is more than the diameter of the small cylinder body, in combustion chamber
High-pressure gas be injected to the ratio expanded in big cylinder body and be greater than in the small cylinder body to the compression ratio of live gas, so this
The efficiency of invention is higher than traditional internal combustion engine.
Description of the drawings
Fig. 1 is the structure diagram of the embodiment of the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Figure 1, its of the invention structure include big cylinder body 1, small cylinder body 11, piston 2, connecting rod 3, cylinder cap 4, bent axle 5, main shaft 6,
Pressure valve 7, snifting valve 8 and spark plug 9；The diameter of big cylinder body 1 than small cylinder body 11 diameter more greatly；Big cylinder body 1 and small cylinder body 11
In be equipped with piston 2；The lower section of piston 2 is equipped with connecting rod 3；The top of big cylinder body 1 and small cylinder body 11 is equipped with cylinder cap 4；It is equipped in cylinder cap 4
Combustion chamber 40；Pressure valve 7 is equipped between small cylinder body 11 and combustion chamber 40；Snifting valve 8 is equipped between cylinder body 1 and combustion chamber 40 greatly；
Spark plug 9 is equipped in combustion chamber 40；The lower end connection bent axle 5 of connecting rod 3；Bent axle 5 and main shaft 6 are coaxially arranged；The one of small cylinder body 11
Side is equipped with inlet valve 10；Intake valve is equipped in inlet valve 10；The side of big cylinder body 1 is equipped with exhaust valve 20；It is equipped in exhaust valve 20
Air bleeding valve.
The present invention works in this way：As shown in Figure 1, the piston 2 in the piston 2 of small cylinder body 11 and big cylinder body 1 is all downwards
Movement, live gas entered from inlet valve 10 in small cylinder body, and then piston rises, and the piston in small cylinder body 11 is by the new of sucking
In fresh gas compression to combustion chamber 40；Spark plug 9 lights the combustion gas in combustion chamber, and then snifting valve 8 is opened；High-temperature high-pressure fuel gas
Being injected in big cylinder body 1 pushes the piston in big cylinder body 1 to move downward acting.Because the diameter of big cylinder body is more than the straight of small cylinder body
Diameter, thus expansion ratio of the combustion gas in big cylinder body be more than small cylinder body in piston to the compression ratio of fresh combustion gases, be equivalent to and passing
The overbottom pressure of tail gas is reused on the basis of the tail gas of the internal combustion engine of system, so the efficiency of internal combustion engine is than in traditional
Combustion engine will height.
