How a pre engaged starter motor works?

The pre-engaged starter motor is fitted with a relay valve which controls the movement of the pinion. … When the starter motor is activated the pinion moves along the shaft until it comes into contact with the toothed ring-gear. The pinion is then interlocked with the ring-gear before rotating to crank the engine.

How does an inertia starter motor work?

Inertia starters work by rotating a pinion and moving it forward through centrifugal force towards the ring-gear. As it continues to spin, the teeth of the pinion lock into the ring-gear and crank the engine. A key advantage of inertia startering is that they automatically disengage once the engine has started.

What does a solenoid do on a pre-engaged starter motor?

The starter solenoid switch enables a relativelj small current to control a very large current of the order of several hundred amperes, and reduces the voltage drop in the starter circuit due to the use of much shorter cables.
