Fuel mixture of I.C. engine must be ignited in the engine cylinder at proper time for useful work. Arrangement of different components for providing such ignition at proper time in the engine cylinder is called Ignition system. There are four different systems of igniting fuel: (1) Ignition by electric spark i.e. spark ignition (2) Ignition by heat of compression i.e. [...]
