automotive aluminium alloys for engines

In addition, the cylinder block and cylinder head of the engine are required to have good thermal conductivity and corrosion resistance, and aluminium alloy has very outstanding advantages in these aspects, therefore, the automobile manufacturers have carried out the development and development of aluminium engine. At present, many foreign automobile companies have adopted the all-aluminium engine cylinder block and cylinder head. Such as the United States General Motors has used a full aluminum cylinder liner; French car company aluminum cylinder liner has reached 100%, aluminum cylinder block up to 45%; Japan's Nissan VQ and Toyota's Lynx IMZ-FEV6 are used in cast aluminum engine oil pan; Chrysler's new V6 engine cylinder block and cylinder head are used aluminum materials.

Germany's advanced 6.0L W12 engine is basically aluminum-magnesium alloy, Audi A8L 6.0 quattro sedan because of the use of W12 engine, the whole weight was subsequently reduced to 1980kg, lower than all other models. The W12 engine's 450hp and 560Nm makes it comparable to a high performance sports car with a weight of 4.7kg per unit of horsepower required to accelerate.

The Polaris engine is GM's top of the range engine, apart from the LS engine range, and is the first V8 aluminium engine with an overhead camshaft in the USA. Its cylinder liners are made of all die-cast aluminium. The 4.6-litre engine currently used in Cadillacs produces 320hp and 427Nm of torque, while the supercharged version used in the high-performance V-Series is capable of up to 476hp/606Nm.
