The generator represents compact "power station" which at the working engine supplies with the electric power of consumers. The generator anchor is resulted in rotation клиновым by a belt and the cranked shaft of the engine rotates almost twice faster, than. Three-phase generators make an alternating current which will be transformed by means of the block of rectifiers to a direct current. The regulator of pressure established behind the generator provides demanded pressure of an onboard network. The generator charges the battery and supplies simultaneously all consumers connected to a network.
The system of regulation of loading by means of РСМ
protects the storage battery. For the cold storage battery the best mode of gymnastics is the raised pressure, and наооборот
, the warm battery is better for charging a sparing mode — with smaller pressure. Taking into account it on the car the difficult monitoring system of loading which block RSM operates is applied. It changes pressure, co-operating with gauges of temperature of soaked up air (IAT) and temperatures in подкапотном
space. The system of regulation of loading counts maximum permissible values of pressure and transfers the pressure given to a regulator. Simultaneously system RSM operates and supervises target pressure of the generator. For example, at a great number of the connected consumers or the discharged accumulator room of the battery the system raises number of turns of idling. That at engine start-up to reduce loading in an onboard chain, on the generator it is switched off internal, and on a diesel engine — external sliding муфта
from a pulley of a shaft of an anchor. Thus the generator starts to work after the engine was started. Do not try to repair car Focus generators independently, it is better to do it in a specialised workshop (fig. 302
