b. The problem In magneto Ignition is to generate a
chamber of the gasoline engine requires an electric
spark of sufficient voltage to Ignite the fuel-air mixture
spark. The electric spark can be produced In two ways:
Instantly and to synchronize the spark with the engine
by magneto Ignition or by battery Ignition. The magneto
cycle so that maximum power will be realized from the

combustion. The fundamental units are listed below:
