InjectionOf fuel by pressure into inlet manifolds (petrol) or combustion chamber (diesel). |
Injection LagA short time delay between actuation and actual operation of an injector. |
Injection TimingPoint within the four-stroke cycle when injection occurs. Similar to ignition timing on petrol engines. |
InjectorControl valve and nozzle used to inject and atomise fuel. |
Injector lagA short time delay between actuation and actual operation of an injector. |
Injector NozzleThe tip of a fuel injector, which is drilled to produce a particular spray pattern. |
Injector Pulse WidthWhen viewed on an oscilloscope, the horizontal width of the trace. This represents the open time of the injector. |
Injector PumpFuel pump that produces the timed high pressure pulses for the injection and timing of fuel delivery on a diesel engine. |
Inlet ManifoldDucting that connects the carburettor/fuel injection components to the inlet ports in the cylinder head. |
Inlet PortsThe way in to the engine for fuel/air mixture. |
