Hemi smart

Hemi (from "hemisphere") is a design of internal-combustion engines in which the cylinder head's combustion chamber is of hemispherical form. The term, "Hemi engine", is a trademark of Chrysler Corporation, though the concept is used by many manufacturers.

The chamber design puts the intake/exhaust valves in-line, rather than side-by-side, allowing for better flow of air through the head. The spark plug in the center of the chamber makes for better ignition of the fuel/air mixture. These aspects help make the hemi-type engine more efficient and powerful.
