The bimetallic cylinder liner has several significant advantages due to its structure and material properties. Firstly, it adopts a combination of two metals with different coefficients of thermal expansion, which can maintain good rigidity at high temperatures, reduce thermal fatigue, and improve engine life. Secondly, the inner metal layer can absorb and disperse heat, reduce cylinder wall temperature, minimize wear, and improve combustion efficiency. In addition, the bimetallic cylinder liner has strong corrosion resistance, which can effectively prevent coolant erosion and extend maintenance cycles. Its lightweight design also helps to reduce engine weight and improve fuel economy. Overall, bimetallic cylinder liners excel in heat resistance, wear resistance, energy efficiency, and reliability, and are an important component of modern engine technology.
