What are the components of an automotive engine's electronically controlled fuel injection system?

[SanAlexandra]

An electronically controlled fuel injection system consists of three main parts: the air supply system (air circuit), the fuel supply system (fuel circuit), and the control system (electrical circuit). Relevant information is as follows: 1. Introduction: The electronically controlled fuel injection system is a system where the engine control unit (ECU) controls the fuel injection timing, injection pulse width, and injection pattern of a gasoline engine. Due to the volatile nature of gasoline, it is easy to form a homogeneous combustible mixture outside the cylinder. Therefore, for a long time, the carburetor supply method installed on the intake manifold was used. This fuel supply system was replaced by the electronically controlled fuel injection method because it could not precisely control the air-fuel ratio of the mixture under different operating conditions. 2. Definition: The full name of the electronically controlled fuel injection system is the electronic control fuel injection system, commonly known as gasoline injection.
