Definition

The car piston is like the central part of the car engine, which occupies an extremely important position when the engine is started. Automobile pistons are used to withstand gas pressure, and through the piston pin, the connecting rod drives the crankshaft to rotate, and the top of the piston is also an integral part of the combustion chamber. The general automobile pistons are divided into three categories: diesel engine pistons, gasoline engine pistons, and general-purpose pistons.

Performance Requirements for Pistons

Since the piston structure becomes “chunky”, the surface area of the piston is reduced in proportion to the entire volume, so it is not conducive to the heat dissipation of the piston. In order to ensure that the piston is not melted and lubricated normally, in addition to some measures must be taken in design to reduce its thermal load; the piston must also be changed and improved in manufacturing, such as the material of the piston, casting and machining, so as to reduce the thermal load. meet its thermal load requirements. In addition, some surface treatments are applied to the piston to improve oil storage and improve lubrication conditions.
