The important role of aluminum diecasting in automobile engine manufacturing(1)

Fuel is the main source of automotive power, and the total weight of the car directly affects how much fuel is consumed. Light metal aluminum has only one-third of iron’s relative density, to meet the requirements of automobile lightweight, light metal aluminum application has got more and more attention in automotive industry, and has been gradually replaced by a batch of steel materials. The most widely application is aluminum die casting.

Reducing vehicle weight, which means reducing inefficient load, can reduce fuel consumption and improve the efficiency of vehicle use. At the same time, the reduction of fuel consumption can directly reduce the pollution caused by automobile emission to the earth environment.

As an important part of automotive power system, the engine is very suitable for aluminum die castings due to its structure and requirements for material properties. In the last 20 years, the application of aluminum diecast parts in world automobile industry has been increasing. The application of aluminum die casting in automobile industry has an outstanding development in Japan. The annual aluminum die casting production has more than 80 % used in automobile manufacturing. In the early 1970s, many Japanese automobile companies began to expand the application of aluminum alloy in automobile engines, and started to use cast aluminum instead of cast iron to produce cylinder head, air intake pipe, and began to produce aluminum engines in small quantities.

In aluminum engine, cylinder block and cylinder head are the most important components.

The cylinder block is the largest and also most complex part. The main advantage of using aluminum alloy instead of cast iron cylinder block is to reduce the fuel consumption by reducing the engine weight greatly. The cylinder head of a car with modern design is made of aluminum alloy.

The aluminum die casting applied in automobile engine manufacturing has been more and more widely, and the aluminum die casting process brings a lot of benefits to the automobile industry, more information, as you can see in article: The important role of aluminum diecasting in automobile engine manufacturing (2).
