NN Inc’s precision machining capability is well-suited for all types of injector system components, including multi-port fuel injectors, gas direct injection systems, diesel fuel injectors, and diesel emission fluid systems. Our manufacturing processes boast a micron (0.001mm) level capability, necessary for producing components such as needles, nozzles, and valve seats.
NN Inc has the capability to manufacture many precision components for injectors, including needles, nozzles, injector tips, valve seats, and fittings.
In a Multi Port Fuel Injection system, fuel injectors are positioned next to each of the engine cylinder intake ports. NN Inc. produces precision components for these injectors, including needles, nozzles, adjustment tubes, valve bodies, and seats.
In gas direct injection systems, fuel injectors are positioned in each engine cylinder to supply fuel directly to the combustion chamber. NN Inc’s manufacturing capabilities encompass all the precision machined components required in the injection system.

Diesel fuel injector systems inject fuel directly into the engine cylinder. The high cylinder pressures characteristic of Diesel engines add complexity to Diesel Injectors. NN Inc.’s manufacturing capabilities cover the many precision components required for Diesel injectors, including needles, valve seats, pistons, and injector disks.

A critical part of Diesel emission SCR systems is the DEF Dose Injectors. DEF, used to eliminate NOx emissions through a chemical reaction, relies on precise injection into the system. NN Inc produces critical components with micron (.001mm) level tolerances to enable precise DEF injection.
NN Inc. has extensive engineering experience with precision machining, grinding, and a diverse group of secondary processes that are well suited to the manufacture of the injector, solenoid, and spool valve components.
