Injector Nozzles

Injector nozzles are the precision components at the tip of a common rail diesel injector, shaping the fuel spray pattern and atomization as fuel enters the combustion chamber. The nozzle’s spray holes, opening pressure and needle response directly affect combustion quality, fuel efficiency and emissions behavior, which is why nozzles are a common replacement part during injector servicing and overhaul.

This category covers common rail injector nozzles for diesel engines used in commercial trucks, agricultural machinery, construction equipment, generator sets and other heavy-duty applications. Because nozzle specifications vary between injector designs and engine calibrations, selecting the correct nozzle depends on the OEM part number or the injector part number it fits.

When preparing an inquiry, include the nozzle part number, the injector it belongs to, and the vehicle model or engine details. CR Diesels supports OEM cross-reference lookups and welcomes bulk inquiries for nozzles used in workshop, fleet maintenance and parts distribution programs.
