System of start of the engine - the general information and safety measures The general information Unique problem of system of start of the engine is maintenance of rotation of the engine with a speed, sufficient for its start. The start system consists of a starter, the storage battery, the switch of ignition, the traction relay and connecting electroconducting. The starter represents the electric motor of a direct current with the mixed excitation and the electromagnetic traction relay established outside. The starter consists of the case or статора with windings of excitation, an anchor with обгонной муфтой, covers with щёткодержателями and the traction relay. At starter inclusion through a winding of the traction relay the current from the storage battery starts to proceed. The relay anchor is involved also contacts become isolated. Simultaneously the relay anchor through приводной the lever provides promotion of a gear wheel with обгонной муфтой, thus the nave муфты turns on screw шлицах a shaft of an anchor of a starter and turns as well a gear wheel that facilitates input of last in gearing with a gear wreath of a flywheel. Through the closed contacts of the traction relay passes a current feeding windings статора both anchors and a starter anchor starts to rotate together with a nave and обгонной муфтой. After start of the engine frequency of rotation of a gear wheel exceeds frequency of rotation of an anchor of a starter. In this case обгонная муфта it is freely turned, and the twisting moment is not transferred from an engine flywheel to a shaft of an anchor of a starter. After release the ignition key the feed circuit of windings of the traction relay through the ignition switch is disconnected, the anchor of the traction relay is wrung out by a spring in a starting position, relay contacts are disconnected also a drive gear wheel leaves gearing with a gear wreath of a flywheel. The starter with the involving relay is located to in parallel cranked shaft of the engine and fixed on the power unit. Starter activation occurs only at the accepted code иммобилизатора the engine, translated in position N or Р selector AT lever (model with АТ), or the squeezed out pedal of coupling (model with Manual transmission). Safety measures At carrying out of any works with system of start of the engine observe following requirements:
