How a Lawn Mower Ignition Works

Identification

• Most lawn mowers currently use a four-stroke engine which requires an electronic ignition. The ignition relates to a series of mechanisms which ultimately allow the engine to run. This functioning depends on the relay of an electrical charge.

Features

• The electrical charge is initiated by the battery in your lawn mower when you turn the key. That charge is subsequently sent to the spark plug which, as is suggested by its name, creates a spark. The spark must then be adequate enough to ignite the mixture of air and fuel present in the cylinders of the mower's engine.

Effects

• When the fuel-air mixture is ignited, the process of combustion occurs running the engine. But the spark plug needs to keep generating sparks in the proper intervals for each cylinder. If this is not happening in those intervals, then you will have problems with your engine operation.
