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.
What do you need to work on small engines?
A small engine mechanic usually needs a high school diploma or the equivalent. Some gain most of their experience on-the-job, especially motorboat and outdoor power equipment mechanics. Other small engine mechanics attend a trade school to earn a certification.
How long do a small engine last?
With normal use and proper maintenance, a lawnmower should expect to last at least 8-10 years. That converts to around 300 to 500 hours for a small engine and 750 to 1000 hours for a bigger engine. But there are many examples where larger ride-on lawnmowers last for a much longer time.

How does a small engine start?
Combustion is nothing more than a controlled explosion that creates your engine’s power, turning it into a usable mechanical force to get work done. In order for the engine to start, combustion requires a carefully choreographed compressed mixture of air, fuel, and spark that’s precisely timed to ignite.
