What Are The Electrical Parts of A Car?

Automobile electrical appliances are the electrical parts (assemblies) installed and used in automobiles, mainly including electrical control systems, sensors and switch assemblies, and other accessories. The electrical control system includes batteries, starters, generators, generator regulators, wiring harnesses, lights (large and small lights, turn signals, fog lights, reversing lights, brake lights, ceiling lights, etc.), flashers, and Fuse boxes. Sensor and switch assemblies include various sensors and switches, instrument assemblies, and electrical controls. Other parts include ignition coils, spark plugs, high-voltage wires, distributors, window motors, wiper motors, heater motors, seat motors, glow plugs, relays, parking sensors, etc. The following are some standard electrical accessories:

Ignition switch

The ignition switch system is a system in fuel machinery, which is composed of a battery, generator, distributor, ignition coil and spark plug, etc. It is a necessary system for engine or engine work. When the gasoline engine is compressed close to the top dead center, the combustible mixture is ignited by the spark plug, so as to burn and do work externally. For this reason, the combustion chamber of the gasoline engine is equipped with a spark plug. The function of the ignition system is to regularly generate electric sparks with sufficient energy between the two electrodes of the spark plug according to the working order of the cylinders.

PTO switches

The PTO switch is a kind of sensor, which converts the change of light intensity between the transmitting end and the receiving end into the change of current to achieve the purpose of detection. PTO switches use optical elements to change light beams in the middle of a propagation medium. Use the light beam to reflect the object, so that the light beam returns instantly after passing through a long distance. The PTO switch is composed of three parts: a transmitter, a receiver, and a detection circuit.

Control unit

An electronic control unit is a small device inside a vehicle. The heart of an ECU is a microcontroller, controlled by embedded software. Its role is to control one or more electrical systems in the vehicle. It is the backbone of the electrical system and directs its work. The electronic control unit receives information commands from the vehicle and uses this information to act as needed. For example, complete a variety of control functions. And in engine control, the computer can finish various functions such as ignition control, fuel injection control, idle speed control, emission control, intake control, and boost control. At the same time, it can enhance vehicle safety such as airbags, seat belts, and central anti-theft door locks. Enhanced car comfort such as adaptive air conditioning, and seat control.
