Abstract
The utility model relates to a four-stroke combustion engine, which comprises a combustion engine body. The periphery of an air inlet pipe port of the combustion engine body is provided with a sealed air storage chamber, and the wall of a crankcase positioned in a chamber body of the air storage chamber is provided with an air outlet and a one-way valve which is arranged at the air outlet part; the wall of the crankcase positioned in the chamber body of the air storage chamber is provided with an air inlet and a one-way valve which is arranged at the air inlet part. With the adoption of the structural characteristic, the air amount going into an air cylinder from the air inlet pipe port of the four-stroke combustion engine can be increased; the operating efficiency of the four-stroke combustion engine is improved, and the effects that fuel is saved, and the environmental pollution is decreased can be played simultaneously.
Description
The utility model relates to a kind of internal-combustion engine, relates to a kind of four-stroke internal combustion engine specifically.
Known existing four-stroke internal combustion engine at intake stroke at the end, because the inflation pressure in the cylinder is lower than the outer air pressure of crankcase body, make the fuel oil in the cylinder when the burning work done, cause burning insufficient owing to lacking oxygen, this has not only reduced the working efficiency of four-stroke internal combustion engine, has also polluted environment simultaneously.
The purpose of this utility model provides a kind of four-stroke internal combustion engine with regard to being at above-mentioned existing in prior technology deficiency.
The purpose of this utility model can realize by following technical measures:
The utility model comprises internal combustion engine main body, is provided with an airtight air storing cavity along the periphery of the described internal combustion engine main body air inlet mouth of pipe; Be positioned at the one-way valve that offers an air outlet on the crankcase nationality wall of this air storing cavity cavity and be arranged on this place, air outlet; Offer a suction port and the one-way valve that is arranged on this suction port place on the crankcase tank wall outside being positioned at this air storing cavity cavity.
For preventing that the crankcase inner engine oil from entering cylinder, in described air storing cavity cavity, be positioned at described air inlet mouth of pipe position and be provided with an oil expeller.
Advantage of the present utility model is provided with an airtight air storing cavity with regard to being by the periphery along the described four-stroke internal combustion engine body air inlet mouth of pipe, be positioned at the one-way valve that offers an air outlet on the crankcase tank wall of this air storing cavity cavity and be arranged on this place, air outlet, and offer a suction port on the crankcase tank wall outside being positioned at this air storing cavity cavity and be arranged on the one-way valve at this suction port place, make pistons work when compression and exhaust stroke, air is sucked in the crankcase body by described suction port; And when backward stroke of the piston, the air that sucks in the crankcase body is pressed in the described air storing cavity by described air outlet, thereby increased from the four-stroke internal combustion engine air inlet mouth of pipe and entered air quantity in the cylinder, make the fuel oil in the cylinder when work done, be able to abundant burning, this has not only improved the work doing efficiency of four-stroke internal combustion engine, the effect that also play simultaneously and save fuel oil, reduces environmental pollution.
Fig. 1 cuts open figure for master of the present utility model.
The utility model describes in further detail below in conjunction with specific embodiment (accompanying drawing):
As shown in the figure, the utility model comprises internal combustion engine main body 1, is provided with an airtight air storing cavity 3 along the periphery of the described internal combustion engine main body 1 air inlet mouth of pipe 2; Be positioned at the one-way valve 6 that offers an air outlet 5 on the crankcase nationality wall 4 of these air storing cavity 3 cavitys and be arranged on these 5 places, air outlet; Offer a suction port 8 and the one-way valve 9 that is arranged on these suction port 8 places on the crankcase tank wall 7 outside being positioned at these air storing cavity 3 cavitys.For preventing that the crankcase inner engine oil from entering cylinder, in air storing cavity 3 cavitys, be positioned at the described air inlet mouth of pipe 2 positions and be provided with an oil expeller 10.
