What Is the Type of Piston Used in Chrysler HEMI Engines
The Chrysler HEMI engine was first manufactured in the 1950s. Variables in piston design include the piston type, piston pin types and number of rings found on each piston.
HEMI Engines
Hemispherically-shaped combustion engines (HEMIs), first manufactured by Chrysler in the 1950s, were further developed in the 1960s and 1970s. Newer versions are considered lightweight compared to similar engines.
Types
Chrysler HEMI engines use a horizontal slot piston with a steel strut. They use free floating piston pins and have three rings per piston. They are manufactured using an aluminum alloy with a tin coat.
Longevity
Some Chrysler HEMI engine blocks, such as the 6.1-liter engine, come with revised coolant channels and oil jets used to cool the pistons. This decreases wear and increases the devices longevity.
