Chrysler Hemi engine

A Chrysler Hemi engine is one of three different internal combustion engine families from the Chrysler Corporation (or its successor, DaimlerChrysler) that are Hemi engines; in other words, they utilise a hemispherical combustion chamber. A hemispherical cylinder head allows the valves to be inline rather than side-by-side, which gives a straighter, simpler airflow path, allows large valves, and gives greater efficiency. The hemi design places the sparkplug in the center, giving more even ignition.

The advantages of the hemi cylinder head come at the disadvantage of requiring intake and exhaust valve stems that point in different directions, requiring much more complicated rocker arm setups in overhead valve engines. These also increase the space taken up by the cylinder head; Hemi engines are not space-efficient.

The three generations of Chrysler hemi engines included the first (the Chrysler FirePower engine) in the 1950s, the second from the mid 1960s through the mid 1970s, and finally in the early 2000s.
