Since internal combustion engine pistons work under high temperature, high pressure and high load conditions, the requirements for pistons are relatively high, so we mainly talk about the classification of internal combustion engine pistons.

Internal combustion engine piston structure

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.

Piston Working Conditions

Large heat load: when the piston is working in the cylinder, the top surface of the piston bears the action of transient high-temperature gas, and the highest temperature of the gas can reach 2000~2500 C, so the temperature of the piston top is also very high. Inhomogeneous temperature distribution with high thermal stress:

Piston Design of Automobile Internal Combustion Engine

The fierce competition in the automobile market has prompted the manufacturers to greatly shorten the product development cycle; the rapid development of the engine towards supercharging, high power, and light weight has made researchers pay more attention to the improvement of the engine structure. As the heart of the engine, the piston is a component with relatively high technical content. Due to its harsh working conditions, high mechanical and thermal loads often lead to cracking of the piston pin seat, early wear of the ring groove, thermal cracking of the throat edge of the combustion chamber on the top surface of the piston, and other faults.
