Technical characteristics


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

1 – the wire plug 50 (from the ignition lock);
2 – the wire plug 30 (from the accumulator);

3 – a wire from the electromagnetic switch to a starter;
4 – starter.

  • At turn of the ignition key tension comes to the situation "Start-up" on the plug 50 of the electromagnetic switch 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.
  • When coupling a gear wheel the electromagnetic switch includes the total current of the accumulator arriving from the plug 30, and only after the gear wheel enters grooves, the starter powerfully scrolls the engine.
  • The engine of a starter and gear wheel are connected by the lowering transfer. Therefore the electric motor rotates much quicker than a gear wheel. At the expense of it at a starter higher kinetic energy.
  • If the engine was started, the gear wheel leaves gearing with a flywheel wreath.
