Copeland D6 Piston is the "heart" of automobile engines. It bears alternating mechanical and thermal loads and is one of the key components in the engine with the worst working conditions. The function of the Copeland D6 Piston is to withstand the gas pressure and transmit it to the connecting rod through the piston pin to drive the crankshaft to rotate. The top of the piston is also an integral part of the combustion chamber.

The types of Copeland D6 Piston are generally divided into: diesel engine pistons, gasoline engine pistons, and general-purpose pistons.

The function of the Copeland D6 Piston is to withstand the gas pressure and transmit it to the connecting rod through the piston pin to drive the crankshaft to rotate. The top of the piston is also an integral part of the combustion chamber. Working conditions The piston works under the conditions of high temperature, high pressure, high speed and poor lubrication. The piston is in direct contact with the high temperature gas, and the instantaneous temperature can reach more than 2500K. Therefore, the heating is serious and the heat dissipation conditions are very poor. Therefore, the temperature of the piston is very high when working, the top is as high as 600-700K, and the temperature distribution is very uneven; the top of the piston bears The gas pressure is very high, especially when the work stroke pressure is the highest, the gasoline engine is as high as 3～5MPa, and the diesel engine is as high as 6～9MPa. ~12m/s) reciprocating motion, and the speed is constantly changing, which produces a large inertial force, which makes the piston subject to a large additional load. Pistons working under such harsh conditions will deform and accelerate wear, as well as additional load and thermal stress, as well as being chemically corroded by the gas.

As internal combustion engine pistons work under high temperature, high pressure and high load conditions, the requirements for Copeland D6 Piston are relatively high, so I mainly talk about the classification of Copeland D6 Piston.

1. According to the fuel used, it can be divided into gasoline engine piston, diesel engine piston and natural gas piston.
2. According to the material of the piston, it can be divided into cast iron piston, steel piston, aluminum alloy piston and combined piston.
3. According to the process of making piston blanks, it can be divided into gravity casting piston, squeeze casting piston, and forged piston.
4. According to the working conditions of the piston, it can be divided into two categories: non-pressurized piston and pressurized piston.
5. According to the purpose of piston, it can be divided into car piston, truck piston, motorcycle piston, marine piston, tank piston, tractor piston, lawnmower piston, etc.
