Chrysler Hemi Engine

The Chrysler Hemi engine, known by the trademark Hemi, is a series of V8 engines built by Chrysler with a hemispherical combustion chamber. Three different types of Hemi V8 engines have been built by Chrysler for automobiles: the first (known as the Chrysler FirePower engine) from 1951–1958, the second from 1964–1971, and the third beginning in 2003. Although Chrysler is most identified with the use of Hemi as marketing term, many other auto manufacturers have incorporated similar designs.

During the 1970s and 1980s, Chrysler also used the Hemi name for their Australian-made Hemi-6 engine and applied it to the 4-cylinder Mitsubishi 2.6L engine installed in various North American market vehicles.
