The cylinder block made of aluminum alloy has the advantages of low specific gravity, corrosion resistance, fast heat conduction and fuel saving.
The engine block is mostly made of aluminum alloy. From the point of view of use, the advantage of cast aluminum cylinder block is light weight, and fuel saving is achieved by reducing weight. In the same displacement engine, the use of aluminum cylinder engine can reduce about 20 kilograms. For every 10% reduction in the car's own weight, fuel consumption can be reduced by 6% to 8%. According to the latest information, the weight of foreign cars has been reduced by 20% to 26% compared with the past. For example, the Focus uses an all-aluminum alloy material, which reduces the weight of the body, enhances the heat dissipation effect of the engine, improves the efficiency of the engine, and has a longer life.
