Fuel injection is a system for admitting fuel into an internal combustion engine.

It has become the primary fuel delivery system used in automotive engines, having replaced carburetors during the 1980s and 1990s. A variety of injection systems have existed since the earliest usage of the internal combustion engine.

When signalled by the engine control unit the fuel injector opens and sprays the pressurised fuel into the engine.

The duration that the injector is open (called the pulse width) is proportional to the amount of fuel delivered.

Depending on the system design, the timing of when injector opens is either relative each individual cylinder (for a sequential fuel injection system), or injectors for multiple cylinders may be signalled to open at the same time (in a batch fire system).
