14.2. General informationThe electric equipment of the engine includes system of ignition, a charging and start. As these systems treat the engine, they are considered separately from body electric equipment. Consumers incorporate to the plusovy power supply a wire, and with minus – through a car body (weight). Such method allows to reduce number of wires and to simplify installation. On cars low-served or unattended accumulators are established. The electric system has a dvenadtsativoltovy food with negative grounding and consists of the accumulator, the generator, a starter, consumers of the electric power and electric chains. The battery charging is made from the generator which is put in action by a belt from a pulley of a cranked shaft. The starter is represented электродви by a gatel of a direct current with the mixed excitement with the electromagnetic traction relay. At engine start the traction relay moves a leading gear wheel to gearing with a gear wreath of a flywheel before the starter will receive a food from the accumulator. After engine start the coupling of a free wheeling disconnects a starter anchor from a gear wreath of a flywheel. Precautions At works on electric system not to damage a semi-wire nikovy devices (diodes and transistors) it is necessary to fulfill the following requirements: – in operating time of the engine do not disconnect the accumulator, the generator of an alternating current or any electric sockets; |
