Ford/Navistar 7.3 Liter HEUI Injectors

These injectors include the HEUI™ fuel system that features an integrated fuel pump within the fuel injector assembly. This highly engineered fuel system provides performance and efficiency and requires an extensive understanding of the unit’s operating principles during the remanufacturing process.

FSEG engineers analyzed subassembly performance parameters such as: Valve Opening Pressure (VOP), Nozzle Steady Flow, Current Rise Time, etc. They determined the best methods to trim the Control Valve’s performance to achieve targeted fuel delivery quantities and injection timing for peak engine performance and optimal combustion. The Control Valve is the heart of the injector’s performance, and if the Control Valve is not trimmed and adjusted properly relative to the injector’s subassembly performance parameters, injection timing and delivery will be compromised, as will ultimately engine performance.
