Description
Technical field
The present invention relates to a kind of power engine parts and application thereof, particularly a kind of gasoline engine part and application thereof.
Background technique
Petrol engine is a kind of dynamic power machine that uses gasoline for the fuel.Partly form by cylinder, connecting rod, gas distribution system, oil supply system, lubrication system and ignition system etc.; Cylinder head is provided with intake duct and air outlet flue, and forms the firing chamber face jointly with cylinder, thereby, belong to the parts of petrol engine outbalance.Gasoline act as a fuel with AIR MIXTURES in the firing chamber internal combustion, produce great amount of heat, be used for as driving energy.
The gas distribution system of petrol engine is the necessary parts that guarantee the normal operation of petrol engine, generally comprises intake valve and exhaust valve that said cylinder head is provided with, and the opening and closing of intake valve and exhaust valve are controlled respectively by driving components such as rocker arm assemblies; Said intake valve and exhaust valve are respectively equipped with the Rocker arm assembly that drives its switching.
Intake valve and exhaust valve are used for opening, closing gas-entered passageway and exhaust passage, adapt to air-breathing, work by combustion and exhaust phase in the firing chamber, keep the normal operation of petrol engine.Therefore, the layout of inlet and exhaust valve and intake and exhaust channel plays crucial effects for normal air inlet, burning and the exhaust of firing chamber.
The opening and closing of intake valve and exhaust valve generally drive the acting in conjunction realization of assembly through return spring and rocking arm.In the prior art, the rectangular arrangement of rocking arm and valve, just arranged side by side and approaching parallel rocking arm, intake and exhaust channel and valve adapt, and the certain spacing that need stagger influences the intake and exhaust quality; This shows that existing valve is arranged and not only occupied bigger space, and can not adapt the power of reduction petrol engine, and influence discharging with the intake and exhaust direction of gas-entered passageway and exhaust passage; Particularly for the structure of inclined valve, further increase takes up room, and has influence on the layout of other parts (like Carburetor/parts such as empty filter).
Theory thinks that inclined valve generally is beneficial to organizes air inlet, reduces intake and exhaust resistance, also just is beneficial to the efficient operation that improves petrol engine, reduces discharging.But for petrol engine, the inlet and exhaust valve on the cylinder head arranges to have narrow limitation, adopts inclined valve can increase the layout scope of valve, simultaneously, influences the layout of other parts (like Carburetor/parts such as empty filter); Particularly, adopt inclined valve then can have influence on the layout of push rod and camshaft for the vertical shaft petrol engine of lower arranging cam axle.
Therefore; Need improve petrol engine valve cylinder head, be convenient to reduce taking up room of valve and rocking arm under the prerequisite of other arrangements of components; Intake and exhaust channel can be provided with according to the intake and exhaust needs; And can the employing inclined valve, roll stream and intake swirl in the air inlet of cylinder inner tissue, improve intake efficiency; Increase flow perturbation in the cylinder; Accelerate burning, reduce exhaust resistance, improve engine power and reduce discharging.
