In a two-stroke engine, the piston also performs the task of changing air. It requires a large load capacity, high temperature resistance, a small expansion coefficient (the shape of the piston skirt is elliptical the size of the part being heated is slightly smaller), corrosion resistance, etc. Control the engine oil in the crankcase so that it enters excessively into the combustion chamber. Effectively transfers heat from the top of the piston to the cylinder block heat sink. Effectively prevent strong contact between the piston and the cylinder wall. High Wear Resistance The piston ring is made of high-performance materials with excellent wear resistance, which can effectively reduce friction and extend the service life of the motor. Reduce Fuel Consumption: The piston ring can ensure better airtightness and sealing, thereby reducing fuel waste and improving fuel economy.
