The main function of the engine bracket is to support and protect the engine, disperse the weight and vibration of the engine, and prevent the engine from contacting or colliding with the vehicle body during driving.
Cast iron is a traditional and widely used engine bracket material.
The advantages of cast iron engine brackets are high strength, good wear resistance, and the ability to withstand large loads and impacts. The cost of cast iron is relatively low, and the manufacturing process is relatively mature.
However, the disadvantages of cast iron engine brackets are also obvious. They are heavy, which will increase the overall weight of the vehicle, thereby affecting fuel economy. In addition, cast iron has poor thermal conductivity, which is not conducive to the heat dissipation of the engine.
