OIL SPRAY NOZZLE ASSY

An injector (nozzle) is the component that sprays a precise amount of fuel into the engine's combustion chamber.

At high pressure it atomizes diesel into a fine mist at the right moment so it burns cleanly and completely; injection timing and quantity affect power and emissions.

Injectors fit into the cylinder head, one per cylinder. The correct injector matches the engine model and fuel system, and faults are best diagnosed by a qualified technician.
