The Different Types of Ignition Systems

Gasoline-fueled piston engines require an ignition source to set off the explosion that converts the chemical potential energy of the air-fuel mixture into thermal energy which the engine can convert into mechanical energy. Each type of ignition source has advantages and disadvantages (which we’ll get to soon), but all have the same basic objective, which …
