Toyota Starting Systems

Starting the engine is possibly the most important function of the vehicle's electrical system.
The starting system performs this function by changing electrical energy from the battery to mechanical energy in the starting motor.

This motor then transfers the mechanical energy, through gears, to the flywheel on the engine's crankshaft.
During cranking, the flywheel rotates and the air-fuel mixture is drawn into the cylinders, compressed, and ignited to start the engine.
Most engine require a cranking speed of about 200 rpm.
