Engine Piston Spare Parts

The piston is part of the combustion chamber, which is often made into different shapes, the gasoline engine piston by at most flat or concave, so that the combustion chamber has the advantages of compact structure, small cooling area, the manufacturing process is simple. The convex head piston used in the two stroke gasoline engine. Diesel engine piston top often prepared into various pits.
The piston head is the seat of the part above the piston pin, piston head of the piston ring, to prevent the high temperature, high pressure gas into the crankcase, and prevent oil from entering the combustion chamber; the top of the piston absorbed most of the heat also passed to the cylinder through the piston head, and then through the cooling medium.
Ring groove of the piston head has a plurality of processing installation of piston rings, piston ring number depends on the sealing requirements, it is related with the speed and engine cylinder pressure. The ring number of high-speed engine than low speed engine less than the ring number of gasoline engine.
