Delphi offers a comprehensive range of high quality nozzles and injectors manufactured to the most stringent standards. We also offer a wide range of all-makes nozzles for popular applications, as well as a remanufactured injectors, assembled, tested and ready to fit.

Injectors
Directly secured to the engine cylinder head, the injector introduces fuel into the engine in the best form for optimum combustion. This requires the breaking down of fuel into tiny droplets, ranging in size from twenty to one hundred microns diameter, and spreading the droplets evenly through the combustion chamber.

In the more technically advanced diesel systems (ie. DPCN), the nozzle holder acts as a sensor for measuring the injection flow rate and sends this information back to the electronically controlled pumps.

Nozzles
The nozzle is designed to close rapidly at the end of the injection phase to prevent hot gases forcing their way back up into the injector itself. Consequently, it is subject to extremes of pressure and temperature. Delphi has adopted the high standards demanded by vehicle manufacturers to ensure quality, longevity and reliability in our range of nozzles.

Delphi strongly recommends that nozzle sets are replaced every 31,068 miles (50,000km) and the injectors replaced every 62,136 miles(110,000km). This will reduce fuel consumption, increase engine lifetime and reduce emissions.

All-Makes Range
We also offer a wide range of All-makes nozzles for popular applications. These are manufactured to the same demanding standards for quality and precision as the OE product.
