Composition of automobile electrical equipment
Power supply system. The functions of automobile power supply system are mainly power generation, power storage and power supply. It consists of two parts: storage battery, generator and regulator. When the engine does not work or the rotation speed is lower than the generator rotation speed, the battery supplies power; When the engine exceeds a certain speed, the generator generates electric energy, which not only supplies power to the electrical equipment, but also charges the battery (stores electricity). The function of the regulator is to keep the output voltage stable when the generator generates electricity.
Electrical equipment. Electrical equipment mainly consists of the following systems. Robbery initiation system. Starting system is used to start the engine, mainly including starter and its control circuit. Ignition system is used to generate electric spark and ignite combustible mixture in gasoline engine cylinder. It can be divided into traditional ignition system, electronic ignition system and microcomputer controlled ignition system. Traditional ignition system includes storage battery, ignition switch, ignition coil and additional resistor, distributor (breaker, distributor, capacitor, ignition advance regulator), spark plug, high voltage wire, etc. Electronic ignition system includes storage battery, ignition switch, ignition coil, signal generator, ignition controller, igniter, spark plug, high voltage wire, etc. Microcomputer controlled ignition system includes battery, ignition switch, sensors (including crankshaft position, camshaft position, etc.) and engine.
Automotive electronic control system mainly refers to various systems that use microcomputer control, including electronically controlled fuel injection systems, electronically controlled ignition systems, electronically controlled automatic shifting systems, brake anti-lock systems, electronic control suspension systems, automatic cruise systems, airbags Wait. The adoption of the electronics can make the various systems on the automotive work state, achieving the purpose of improving vehicle power, economy, safety, comfort, and reducing automotive pollution emissions.
The whole vehicle circuit and power distribution device include a central junction box, an insurance device, a relay, a wire beam, a plug, a circuit switch, and the like, which makes the full vehicle circuit constitute a unified-integral. In addition to the electronic control device involving traditional electrical equipment, it is only a brief introduction to the system such as electronically controlled fuel injection, electronic control automatic transmission, brake anti-lock.
Auxiliary electrical equipment includes electric fan, window cleaning device (wiper, scrubber, defrosting device), electric window, electric seat, electric rearview mirror, car anti-theft device, automotive air conditioner, car audiovisual system, etc. The auxiliary electrical equipment has a growing trend, mainly developing comfort, entertainment, security safety. The higher the luxury of the vehicle, the more the auxiliary electrical equipment.
The automotive appliance is the appliance component (total) installed on the car, mainly including start-up, power generation, lighting (lighting) system, instrument system, ignition system, auxiliary electrical equipment, etc. Specific: battery, starter, generator, generator regulator, harness, headlight (large, small light, steering lamp, fog lamp, reversing lamp, brake light, ceiling light, etc.), flash, fuse box , Various types of sensor, instrument assembly, various electrical switches, ignitors, ignition coils, spark plugs, high voltage lines, substanders, windows, wiper motors, warm wind motors, seat motors, preheating plugs, relays, Fuel oil pump, ECU (car), fuel heater, cigarette lighter, audio equipment, clock, car phone, navigation device, reversing radar, etc. Refers to the ignition system of the engine. The ignition system is a system in a fuel machine, composed of a battery, a generator, a substator, an ignition coil, and a spark plug, and a necessary system for engine or engine. The role is that the gasoline engine is ignited by the spark plug, thereby burning a spark plug in the combustion chamber of the gasoline engine in the combustion chamber of the gasoline engine. The function of the ignition is to generate sufficient energy in the spark plug two electrodes in the working order of the cylinder.
