Straight-three engine

The Inline-three engine or Straight-three is an internal combustion engine with three cylinders. The cylinders are positioned in a straight line along one crankshaft. It can be powered by different types of fuels, including gasoline, diesel and natural gas.

Inline threes are used in cars less often than inline fours. Due to generally smaller engine sizes, inline threes tend to use less fuel to operate and less resources to build.
