Engine Parts Piston 612600030010  is used for  Weichai WD615, WD10, WP10, WP12 Construction Machinery Diesel Engines . Piston is the reciprocating movement part in the cylinder body of automobile engine.The basic structure of piston can be divided into top, head and skirt.The top of piston is the main part of combustor and its shape is related to the combustor form.Gasoline engine adopts flat top piston, which has the advantage of small heat absorption area.Diesel piston top often has a variety of pits, its specific shape, location and size must be in line with the diesel mixture formation and combustion requirements. The whole piston can be divided into three parts: piston top, piston head and piston skirt. The main function of the piston is to bear the combustion pressure in the cylinder and transfer the force to the crankshaft through the piston pin and connecting rod.In addition, the piston and cylinder cover, cylinder wall together constitute a combustion chamber. 

Piston top is the combustor components, so often made into different shapes, gasoline engine piston top adopts flat or concave top, so as to make the combustor structure compact, small heat dissipation area, simple manufacturing process.Convex piston is often used in two – stroke gasoline engines.The piston top of diesel engines is often made into various pits. The piston head is the part above the piston pin seat. The piston head is equipped with a piston ring to prevent high-temperature and high-pressure gas from entering the crankcase and oil from entering the combustion chamber.Most of the heat absorbed by the top of the piston is also transferred to the cylinder through the head of the piston, and then through the cooling medium.

Piston head processing several rings installed piston ring groove, the number of piston rings depends on the requirements of sealing, it is related to the engine speed and cylinder pressure.High speed engines have fewer cycles than low speed engines, and gasoline engines have fewer cycles than diesel engines.General gasoline engine USES 2 gas rings and 1 oil ring;The diesel engine has three gas rings and one oil ring.The low speed diesel engine USES 3 ~ 4 air rings.In order to reduce the friction loss, the height of the ring belt should be reduced as far as possible.
