Description
The engine is designed to power a lawn mower blade in order to cut grass faster, easier, and more efficiently than man powered mowers and previous engine models. The engine in particular that was dissected and analyzed was a four-stroke lawn mower engine manufactured by Briggs and Stratton.
How It Works
This engine works on a four-stroke cycle. A manual crank starts the cycle while creating a vacuum to draw gas and air into the cylinder. Concurrently, an electrical current is produced to create a spark which would ignite the fuel-air mixture compressed in cylinder by the piston. This piston turns the camshaft through a linear-to-rotational energy conversion. The camshaft then turns the output of the motor, which is a blade, to cut the grass.
