[China Aluminum Network] Currently, the cylinder block of gasoline engines is divided into cast iron and cast aluminum. In diesel engines, cast iron cylinders account for the majority. In recent years, with the rapid development of the automobile industry, cars have quickly entered the lives of ordinary people. At the same time, the fuel-saving performance of vehicles has gradually been taken seriously. Reducing the weight of the engine can save fuel, while the cast aluminum cylinder can reduce the weight of the engine.
From the point of view of use, the advantage of the cast aluminum cylinder body is its light weight, which saves fuel by reducing the weight. In an engine of equal displacement, using an aluminum cylinder engine can reduce the weight of about 20 kg. Every 10% reduction in the car's own weight, fuel consumption can be reduced by 6% to 8%. According to the newer data, the weight of foreign cars has been reduced by 20% to 26% compared with the past. For example, Fox uses all aluminum alloy material, while reducing the body weight, but also enhance the engine's cooling effect, improve the engine's working efficiency, and longer life. From the perspective of fuel economy, the advantages of cast aluminum engines in terms of fuel economy have attracted considerable attention.
In addition to the difference in weight, there are many differences between the cast iron cylinder and the cast aluminum cylinder in the production process. The cast iron production line has a large area, which has large environmental pollution and complicated processing technology. The production characteristics of cast aluminum cylinders are exactly the opposite. From the perspective of market competition, cast aluminum cylinders have certain advantages.
