Of fuel by pressure into inlet manifolds (petrol) or combustion chamber (diesel).

A short time delay between actuation and actual operation of an injector.

Point within the four-stroke cycle when injection occurs. Similar to ignition timing on petrol engines.

Control valve and nozzle used to inject and atomise fuel.

A short time delay between actuation and actual operation of an injector.

The tip of a fuel injector, which is drilled to produce a particular spray pattern.

When viewed on an oscilloscope, the horizontal width of the trace. This represents the open time of the injector.

Fuel pump that produces the timed high pressure pulses for the injection and timing of fuel delivery on a diesel engine.

Ducting that connects the carburettor/fuel injection components to the inlet ports in the cylinder head.

The way in to the engine for fuel/air mixture.
