This course introduces learners to Electronic Fuel (Petrol) Injection (EFI) Maintenance, focusing on the principles, components, operation, and basic diagnostics of modern gasoline fuel injection systems. The course explains how EFI systems use fuel pressure and electronic control, rather than engine vacuum, to deliver precise amounts of fuel to the engine, resulting in improved performance, fuel efficiency, and reduced emissions compared to traditional carburetor systems.
Learners are guided through the classification of fuel injection systems, including single-point (throttle body), multi-point (port injection), direct injection, and indirect injection systems. Emphasis is placed on understanding how fuel injection location and pressure affect engine operation and efficiency.
The course also covers the major components of an EFI system, such as the fuel tank, electric fuel pump, fuel filter, electronic control unit (ECU), common rail, pressure sensor, injectors, and fuel lines. The role of the ECU in controlling fuel quantity, ignition timing, and idle speed is clearly explained. Additionally, learners gain insight into the working principle of the EFI system, from fuel delivery and pressure regulation to injector operation.
By the end of the course, learners develop foundational skills in EFI system operation, component identification, and basic maintenance concepts essential for modern automotive technology.
