The general information and safety measures
The general information
The generator of the alternating current which has been built in it a regulator of pressure, control lamp of a charge, the storage battery, protective fusible insert and electroconducting connecting listed components concern number of components of system of a charge. The charge system provides giving of an electric food to ignition system, lighting and alarm devices, a radio receiver and other consumers of the electric power. The generator is put in action by a belt drive from a pulley of a cranked shaft and established in a forward part of the engine. The additional information on electric connections of components of system of a charge can be gathered from schemes of electric connections (the Onboard electric equipment see the Head).
The electronic block of management (ECM, depending on current values of entrance parametres (engine turns, speed of movement of the car, temperature of a cooling liquid, quantity of the included consumers of the electric power and temperature of soaked up air), makes updating of size of pressure developed by the generator. The system main task is loading minimisation on the engine.
Problem of a regulator of pressure is restriction of pressure developed by the generator in the set limits. The regulator prevents overloads of contours and the other unpleasant phenomena connected with jumps of pressure.
The charge system does not require regular service. Nevertheless, it is necessary to check periodically a condition приводного a belt of the generator, the battery, connecting electroconducting and it клеммных connections (Routine maintenance see the Head).
The control lamp of a charge built in in an instrument guard quickly joins at ignition key turn in position ON. Right after realisation of start of the engine the lamp should go out. Refusal of a lamp of deenergizing testifies to malfunctions in charge system (Removal and installation of components of system of preheat see). On some models in an instrument guard the voltmeter allowing to the driver in time to trace a deviation of onboard pressure from norm is in addition established. At an exit of indications of the voltmeter for limits of an admissible range it is necessary to make check of system of a charge (Removal and installation of components of system of preheat see).
The fusible insert represents the short piece of the wire placed in isolation which have been built in in the main plait of electroconducting of an impellent compartment. The total section of a vein of a conductor of an insert several times is less than at chain electroconducting in which it is included that guarantees reliable protection of last against an overload.
At joining клеммных connections of electric chains equipped with the generator of an alternating current of cars it is necessary to observe special safety measures:
The general information
The system provides проворачивание the engine for the purpose of its start.
The basic components of system are a starter with the traction relay established on it, the storage battery, the lock of ignition and connecting electroconducting.
Assemblage of a starter with the traction relay is fixed from above on the power unit, near to a transmission dome.
At ignition key turn in position START power supplies from the battery on a chain of management of start move on the traction relay of a starter. The relay makes switching of a food of the battery directly on the starter electromotor. The motor starts to rotate, simultaneously turning for a gear wreath of a flywheel / приводного a disk a cranked shaft of the engine.
Starter functioning on the models equipped manual transmission, becomes possible only at the squeezed out pedal of coupling. On models with АТ an indispensable condition is transfer of the lever of the selector in position «Р» or «N».
At performance of any works with components of system of start it is necessary to observe following special safety measures:
