Question: How does a small engine work?

Small engines are a type of combustion engine, which runs on an explosion between fuel and a spark. The explosion creates heat energy that the mechanical parts in the engine use to power the equipment. … During this stroke, the fuel-air mixture is compressed between the cylinder head and the piston.

How does a 4 stroke small engine work?

A very high voltage is created in the ignition coil. The spark plug enables this high voltage to be discharged into the combustion chamber. The heat created by the spark ignites the gases, creating rapidly expanding, super-heated gases that force the piston back down the cylinder bore. This is called the power stroke.
