Starter

The starter is on the right party of the engine (here it is shown in the four-cylinder engine)


1 – the plug of 50 wires (from the ignition lock); 2 – the plug of 30 wires (from the accumulator);	3 – a wire from the electromagnetic switch to a starter; 4 – a starter.

At ignition key turn in position "Start-up" pressure arrives on the plug 50 electromagnetic switches, located above on a starter.
As a result of it the starting lever shifts a starter gear wheel on an abrupt carving in a gear wreath of a flywheel of the engine.
At gear wheel coupling the electromagnetic switch includes the total current of the accumulator arriving from the plug 30, and only after the gear wheel enters into grooves, the starter powerfully scrolls the engine.
The engine of a starter and gear wheel are connected by lowering transfer. Therefore the electric motor rotates much faster gear wheels. At the expense of it at a starter higher kinetic energy.
If the engine was got, the gear wheel leaves gearing with a flywheel wreath.
