Products Details

Introduction of the piston

The piston is a reciprocating part in the cylinder block of an automobile engine. The basic structure of the piston can be divided into top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the selected form of the combustion chamber. Gasoline engines mostly use flat-top pistons, which have the advantage of small heat-absorbing areas. There are often various pits on the top of the piston of a diesel engine, and its specific shape, position and size must be adapted to the requirements of the mixture formation and combustion of the diesel engine. The main function of the piston is to withstand the combustion pressure in the cylinder and transmit this force to the crankshaft through the piston pin and connecting rod. In addition, the piston also forms the combustion chamber together with the cylinder head and cylinder wall. With the increasingly stringent requirements for the power, economy, environmental protection and reliability of the engine in the whole vehicle, the piston has developed into a multi-component assembly integrating light-weight and high-strength new materials, special-shaped outer circle composite profiles, special-shaped pin holes, etc. A high-tech product integrating two new technologies to ensure the heat resistance, wear resistance, stable guiding and good sealing function of the piston, reduce the friction work loss of the engine, and reduce fuel consumption, noise and emissions.

Piston Technical Requirements

1. It must have sufficient strength, rigidity, small mass and light weight to ensure the minimum inertial force. 2. Good thermal conductivity, high temperature, high pressure, corrosion resistance, sufficient heat dissipation capacity, and small heating area. 3. There should be a small friction coefficient between the piston and the piston wall. 4. When the temperature changes, the size and shape change should be small, and the minimum gap should be kept between the cylinder wall and the cylinder wall. 5. The thermal expansion coefficient is small, the specific gravity is small, and it has good friction reduction and thermal strength.
