HEUI Injectors for Ford and Navistar diesel engines are available in either rebuilt or brand new versions and are available individually, as sets, or installed in our rebuilt diesel engines. The HEUI design uses a high-pressure oil pump and delivers a constant flow of very high-pressure motor oil to gallery passages in each cylinder head. (Pressures between 500 and 3000 psi). When the electric solenoid on top of a HEUI injector is actuated, this high pressure oil is directed into a chamber inside the injector and provides the hydraulic pressure to force an intensifier piston to move downward. The intensifier piston in turn pushes fuel out into the cylinder. Fuel is injected into the cylinder at pressures as high as 21,000 pounds per square inch. All DSG rebuilt diesel engines for Ford and Navistar applications feature new HEUI injectors.
Alliant Power Injectors look and perform just like the injectors from Ford and Navistar because the same company makes them! While their injectors are remanufactured, Alliant Power injectors are new and come with a superior warranty.
