Ignition System

The engine in a vehicle needs three things to run: air-fuel mixture, sufficient compression, and an ignition source. Fuel is ignited by an electric spark in gas engines. Diesel engines use heat from compression to ignite the air-fuel mixture. This chapter focuses on gasoline engines. The ignition system on vehicles has changed over the years, but its purpose has been the same – to ignite the air-fuel mixture. The ignition system converts fuel’s chemical energy into mechanical energy (wanted motion) and thermal energy (wasted heat). Ignition system advancements have been influenced by progressively stringent emission standards.
