Piston skirt copper ring diesel engine piston is one of the key parts in the diesel engine. It forms a piston group with piston ring, cylinder liner and other parts, and forms the engine combustion chamber with cylinder head. It bears the interaction force of natural gas and according to the cylinder The sleeve and the crankshaft connecting rod send the driving force to the engine crankshaft for the whole process of the internal combustion diesel engine.

Aluminum bronze bronze sleeve Piston ring is a metal ring used to enter the piston groove. Piston rings are divided into two types: shrink ring and automobile oil ring. The shrink ring can be used to seal the combustible mixture in the combustion chamber of the engine; the car oil ring is used to shave unnecessary car oil on the cylinder. The piston ring is a metal material ductile ring with a large outward deformation. It is installed in the opposite annular groove between the two models. The piston ring for reciprocating and rotating fitness exercises, with the help of the pressure difference of the vapor or liquid, produces a seal between the outer circular surface of the ring and the cylinder and one side of the ring and the ring groove.

Centrifugal cast high-lead copper sleeves generally pistons are all cylindrical. According to the working standards and regulations of different diesel engines, the piston itself has various structures. Generally, the piston is divided into three parts: the top, the top and the journal. .

The top of the piston is a key part of the combustion chamber of the engine, and its appearance is related to the way the engine combustion chamber is used. Gasoline engines mostly use sloping roof pistons, which have the advantage that the total area of ​​endothermic reaction is small. There are often various dents on the top of the piston of a diesel engine. The actual appearance, position and size of the piston must be consistent with the regulations of diesel engine mixed gas production and ignition.

The top of the piston head refers to the top of the piston and the part of the ring groove. The part between the top of the piston and the bottom of the piston ring groove is called the top of the piston head. Its function is to bear the air pressure to avoid steam leakage and send the heat to the piston ring. Cylinder wall. A number of ring grooves are cut on the top of the piston head for the installation of piston rings. At most, the gasoline engine piston adopts a sloped roof or a concave roof, which is convenient for making the engine combustion chamber compact.

The piston journal refers to the whole part of the piston ring groove called the piston skirt. Its function is to maintain the vertical posture of the piston as much as possible during repeated motions, which is the guiding part of the piston.
