Abstract
Al-high Si alloys are well known for their use as lightweight components in engineering applications, particularly within the automotive industries, due to their high wear resistance and low thermal expansion. It is desirable to increase the hot strength of these alloys by increasing the Si content. In this work, I have concentrated on the use of Al-high Si alloys for land vehicles. The automobile, engine components, the piston engine, four-stroke cycle and Al-high Si alloys in automotive applications will be discussed in this paper.
