Aluminum alloy is the fastest and most widely used light metal in automobiles, because the performance of aluminum alloy itself has reached the requirements of light weight, high strength and corrosion resistance. The aluminum alloy is greatly enhanced in strength by strengthening alloying elements. Due to its light weight and good heat dissipation, it fully satisfies the working requirements of the engine piston, cylinder block and cylinder head in harsh environments. Aluminum alloy cylinder block and cylinder head die-casting technology can improve the quality control of materials such as purification, refining, refining and deterioration, so that the quality of aluminum castings is consistent and stable. In addition, due to the low density of aluminum alloy, the strength performance is similar to that of gray cast iron, the toughness is higher than that of gray cast iron, and it has good casting performance. Therefore, the application of expanding aluminum alloy can significantly reduce the self-weight of the automobile and reduce energy consumption. This paper focuses on the die-casting of aluminum alloy engine block and the key core technology of the lost foam casting process of aluminum alloy water-cooled double-layer exhaust pipe, the quality problems of casting and the treatment measures.
