Engine with Single Cylinder Arrangement
The easiest engine of all is the single-cylinder plan which produces a power stroke every 720 degrees. With this engine, the head of the piston is connected to the crankshaft through a linking rod. This rod then turns in an oscillating way.

Two-Stroke Engine
There are Chevy owners that broaden their cylinders to a two-stroke engine. This engine includes power pulses of 720 degrees/2. It has a crankshaft rotation of 360 degrees.
With a two-stroke engine, among the pistons remains in the compression stroke. It then waits on its working stroke. At the same time, the other piston remains in the exhaust stroke and will get in the consumption stroke.
