A fuel-injection system delivers measured quantities of fuel to an engine. The injector's design and operation depend on the vehicle's engine and fuel-delivery system.

Common-rail diesel injectors operate within a high-pressure fuel system that supplies fuel to electronically controlled injectors. Other engines use different injection arrangements, including unit injectors and various petrol or diesel injector configurations.
