UCAS Course (2): AUTOMOTIVE Electrical and Electronic Systems

A car fuel injector is a common example of an actuator, responsible for delivering precise amounts of fuel into the engine's combustion chamber. Controlled by the engine's electronic control unit (ECU), the injector opens and closes to spray fuel at the correct timing and pressure, ensuring efficient combustion. This process directly influences the engine's performance, fuel efficiency, and emissions, making the fuel injector a vital component in modern vehicles.
