Electrical parts for Bmw

On-board electrical equipment is a support system for several vehicle systems. In most modern cars, the electrical circuit is designed in such a way that a positive charge (+) passes through the wires and a negative charge (-) passes through the car body. Passenger vehicles have a voltage of 12V on board. The power grids of heavy trucks operate at a voltage of 24V. The main components of the vehicle's electrical equipment are: a rechargeable battery, which is a source of power supply when the engine is not running; an alternator, which is a source of electrical energy when the engine is running; a starter, which is the drive that starts the engine; an ignition system that ignites the fuel-air mixture in the engine cylinders; and a pump that creates overpressure in the fuel system and supplies fuel to the injectors. In addition, electricity is needed to power electronic control units and sensors for control systems, lighting, climate, security, and many others. Without electric drives, it is impossible to turn on and off various transmission modes, open and close doors and windows, adjust seats, operate windscreen wipers, and perform other functions. More
