Dongfeng Cummins C5302254 Piston

The piston is a reciprocating part of the cylinder body 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 component of the combustion chamber, and its shape depends on the type of combustion chamber chosen. Diesel engine piston top often has a variety of pits, its specific shape, position and size must be adapted to the diesel engine mixture formation and combustion requirements.
Technical characteristics:

1, the manufacturing process, the use of the latest steelmaking process greatly improved the material strength, stiffness, small mass, light weight, to ensure the minimum inertia force.

2, good thermal conductivity, high temperature, high pressure, corrosion resistance, with sufficient heat dissipation ability, small heating area.

3. There is 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 clearance between the cylinder wall can be maintained to the minimum.

5. Small thermal expansion coefficient, small specific gravity, good wear reduction and thermal strength.
