Abstract
The present invention relates to petrol engine field, it is specifically related to a kind of chamber structure and includes cylinder cap, inlet valve, piston, head at piston is provided with pit, is provided with gap between dish portion outmost turns and the inlet valve seat ring bottom outlet of cylinder cap of inlet valve, and pit is corresponding with gap coupling.Inlet valve seat ring by air inlet side about 1/2nd enclose in the range of be provided with gap.The beneficial effects of the present invention is: this structure can form good gas in the jar motion, promotes air-fuel mixture in cylinder, optimizes in-cylinder combustion, can effectively promote economy and the emission performance of electromotor in the case of meeting power performance.
Description
Technical field
The present invention relates to petrol engine field, be specifically related to a kind of chamber structure.
Background technology
Increasingly strict along with country's oil consumption and Abgasgesetz, during engine power performance constantly promotes, joint
The vital task also having become gasoline engine can be reduced discharging.According to petrol cycle principle, the compression ratio of gasoline engine is the highest, heat
Efficiency is the highest.Thermal efficiency height means that fuel-economy characteristic is good, and fuel availability is high.But too high compression ratio easily causes gasoline
Machine combustion knock, pinking not only can affect the performance of gasoline engine, also reliability can be caused tremendous influence.
Summary of the invention
It is an object of the invention to solve the problems referred to above, it is provided that a kind of chamber structure.
In order to realize the purpose of the present invention, the technical solution used in the present invention is:
A kind of chamber structure includes cylinder cap, inlet valve, piston, and the head at piston is provided with pit, the dish portion outermost of inlet valve
Being provided with gap between circle and the inlet valve seat ring bottom outlet of cylinder cap, pit is corresponding with gap coupling.
Inlet valve seat ring by air inlet side about 1/2nd enclose in the range of be provided with gap.
The beneficial effects of the present invention is: this structure can form good gas in the jar motion, and in promoting cylinder, oil gas mixes
Close, optimize in-cylinder combustion, can effectively promote economy and the emission performance of electromotor in the case of meeting power performance.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
Embodiment: see Fig. 1 to Fig. 7.
A kind of chamber structure includes cylinder cap 1, inlet valve 2, piston 3, and the head at piston 3 is provided with pit 4, inlet valve 2
Dish portion outmost turns and the inlet valve seat ring bottom outlet of cylinder cap 1 between be provided with gap 5, pit 4 mates corresponding with gap 5.
Inlet valve seat ring by air inlet side about 1/2nd enclose in the range of be provided with gap 5.
Specification: when cylinder cap seat ring bottom hole designs, in the range of the air inlet side about 1/2 of inlet valve seat ring is enclosed, passes through
Cylinder cap seat ring bottom hole structure designs, and makes after having assembled valve, and the dish portion outmost turns of inlet valve 2 there is also with cylinder cap seat ring bottom hole
The structure design of certain interval 5, i.e. Masking gap structure designs.This design main purpose is that strengthening flow enters cylinder cap combustion
Burn guiding function during room, act on when low valve stroke the most obvious.
In engine operation process, inlet valve 2 is opened, and fresh air enters in cylinder from cylinder cap air intake duct.Work as valve stroke
Time less, air-flow passes through the passage between the dish portion of inlet valve 2 and valve retainer, rapidly enters in cylinder.In compression travel, piston
Moving upward, the masking gap structure increased on cylinder cap matches with pit 4 design of piston crown, and with cylinder cap altogether
With constituting a combustor, organize In Cylinder Flow in concert, form certain compression tumble flow.In fuel injection processes, oil
Bundle is injected in the pit of piston crown, it is to avoid oily bundle is injected on casing wall wet wall phenomenon occurs, and beneficially fuel oil is with fresh
The mixing of air, effectively raises Tumble and swirl during low valve stroke, promotes gas in the jar mixing and burning, improves fuel oil
Utilization rate and the raw emissions characteristic of electromotor.
What embodiments of the invention were announced is preferred embodiment, but is not limited thereto, the ordinary skill people of this area
Member, easily according to above-described embodiment, understands the spirit of the present invention, and makes different amplifications and change, but as long as without departing from this
The spirit of invention, the most within the scope of the present invention.
Claims (2)
1. a chamber structure, it is characterised in that: including cylinder cap, inlet valve, piston, the head at piston is provided with pit, enters
