If the engine is the heart of the car, then the 8FC piston can be called the "center" of the heart. What's the point of a small piston? Let's look down.

The 8FC piston function and material.

The main function of the 8FC piston is to withstand the pressure of the combustion gas and transfer this force to the connecting rod to drive the crankshaft to rotate. The working environment of the piston is very harsh, and it is precisely because of the environment of high temperature, high pressure and high reciprocating inertial force that the selection of piston materials becomes very important.

High temperature will bring about a decrease in mechanical strength and abnormal fit, and uneven heating and cooling and high-load operation will cause cracking and deformation of the 8FC piston. Therefore, the piston material must have sufficient rigidity and strength, good thermal conductivity and resistance. High temperature, high pressure and friction, and materials with light weight and low inertia force should be used as much as possible. Aluminum alloy is naturally the best choice; of course, there are still very few pistons that use gray cast iron or heat-resistant steel as materials. .

According to different needs, we can also carry out different surface treatments on the 8FC piston. If we want to reduce the heat absorption of the piston top and increase the thermal resistance, we can do hard film anodizing on the piston top; Cylinder phenomenon and reduced skirt wear, the piston skirt can be tinned, galvanized or coated with graphite.

To sum up, as a high-speed reciprocating and crucial auto part, 8FC piston not only needs the above-mentioned fine designs, but also requires ultra-high-precision machining. It can be seen that this small piston contains a lot of technology .
