Product details

The piston is a critical component of the automobile engine, serving to reciprocate within the cylinder to facilitate energy conversion. Specifically, the piston's functions in the engine include: 1. Energy Conversion: In an internal combustion engine, the piston transforms the heat generated by fuel combustion into mechanical energy. During the working cycle of gasoline or diesel engines, the piston's vertical motion drives the connecting rod and crankshaft rotation, thereby delivering power output. 2. Compression: In a four-stroke engine, as the piston approaches top dead center (TDC), it compresses the air-fuel mixture in the cylinder for gasoline engines or solely compresses air for diesel engines, increasing pressure and temperature to enhance ignition efficiency. 3. Exhaust Emission: During the exhaust stroke, the piston ascends to expel the burned exhaust gases from the cylinder, preparing for the intake of fresh mixture in the subsequent cycle. To ensure efficient and reliable operation, pistons must possess specific design characteristics, such as appropriate material selection (commonly aluminum alloy to reduce weight and improve heat resistance), precise dimensional tolerances, and effective cooling mechanisms. Additionally, the design of piston rings is crucial; they seal the gap between the piston and cylinder wall, prevent combustion gas leakage, and assist in lubricating the piston within the cylinder.
