Transforming Fuel
Into Power.

The Power Stroke® Fuel Injection System.

The advanced-design, high-pressure, hydraulic fuel injectors in Power Stroke® Diesel Engines precisely control the delivery of the fuel into the combustion chamber. The Internal components of the Power Stroke® Diesel's fuel injectors are precisely engineered to the extreme tolerances that are critical to generating peak horsepower and torque as well as meeting stringent Federal emission standards.

Remanufactured to Exacting Standards

To begin with, Motorcraft® replaces the entire coil assembly for each injector to prevent wire fatigue and poor cold-start conditions. Then, high pressure sealing surfaces inside the cylinder head assembly are refinished to original specifications (less than 2 microns of flatness). The precision flatness of these surfaces is critical to high pressure (20,000-plus psi), injection systems and assures long engine life, good mileage and performance.

The injector's intensifier bodies are given new plungers and both components are precision-match honed to operate flawlessly at extreme pressures and temperatures with 100 percent durability and reliability.

All spool valves are replaced with new parts, and both control valve bodies and spools are precision ground to Ford's exacting diametrical tolerance for excellent sealing and oil direction. Competitors re-use the old spool valves.

Top Quality for High Performance

All remanufactured nozzle assemblies are inspected, then chemically treated and micro brushed to remove carbon and fuel residue. Each nozzle is then tested to ensure proper performance and emissions levels – the results: you needn't worry about high carbon buildup, nozzle coking, poor performance or emissions issues.
