HEMI is short for hemispherical, half of a sphere, which is the shape of the combustion chamber in early Hemi engines from Dodge/Mopar and now in modern day Dodge/Chrysler.
The concept behind Hemi is the shape of these chambers to produce maximum airflow. This coupled with 2 valves per cylinder produce high-output horsepower in Hemi engines.
Today through modern technology the Hemi engines have been engineered to produce maximum horsepower while offering substantial fuel economy.

If you mean what makes an engine a hemi, the most obvious design feature noticeable is the spark plugs go through the top of the head rather than the side.
The top of the piston is a domed shape (convex) not flat.

Hemi (from "hemisphere")
Engine using hemispherical-shaped (half of a globe or sphere) combustion chambers. The valves are ****** at 45 degrees from the piston top. Mopars, despite their fame, are not the only cars with hemi heads.

the hemi is built in a hemispherical shape and by that pumps more power!

the cylinder heads in the engine are round so they call them hemis or hemispherical cylinders, which makes the engine run and breathe better.

Hemisphearical combustion head engine... The interor of the heads are dome shaped rather than flat or wedge shaped.
