Structural Characteristics:
Type: Electronic Unit Injector (EUI). It is a combined unit that performs both low-pressure fuel supply and high-pressure injection in one package.
Integrated Design: Contains the solenoid valve, precision plunger and barrel assembly, and nozzle in a single unit, mounted directly in the cylinder head.
Cam-Driven: The injector's plunger is actuated by a dedicated lobe on the engine's camshaft, generating extremely high injection pressure (upwards of 30,000 psi).
Electronically Controlled: A solenoid valve, commanded by the engine's ECM (DDEC), precisely controls the timing and duration of the fuel injection event.
Technical Advantages:
High Pressure & Efficiency: Cam-driven mechanism creates very high injection pressure, leading to superior fuel atomization, more complete combustion, better fuel economy, and lower emissions.
Precision & Responsiveness: Electronic control allows for extremely accurate, cylinder-by-cylinder fuel metering and timing optimization across all engine loads and speeds.
Robustness: The mechanically driven design is inherently durable for heavy-duty, high-mileage applications.
2. Main Application Scenarios & Equipment
Primary Engine: Detroit Diesel Series 60, most commonly the 12.7-liter (DDC 12.7L) engine. May also be used in some 14L versions.
Key Equipment:
Class 8 Over-the-Road Trucks: Freightliner (FLD, Century, Columbia), Western Star, and other trucks equipped with the Series 60.
Coaches & Intercity Buses: (e.g., MCI, Prevost).
Marine Propulsion: In workboats and small vessels.
Stationary Power: Generator sets and industrial power units.
3. OEM Cross-Reference Numbers
Standadyne/Remy Number: REMY 7004110 or 7004-110
Robert Bosch Number: Bosch 0432122008
Delphi Number: Delphi E0902-11B
(Always verify the latest part number compatibility with your engine's serial number and a trusted supplier.)
4. Daily/Maintenance Suggestions for the Injector
The injector itself has no daily service points, but its longevity depends entirely on proper system maintenance:
Fuel Quality is Paramount: Use clean, high-quality, on-road #2 diesel fuel. The ultra-tight tolerances in EUIs are easily damaged by contaminants.
Rigorous Fuel Filtration:
Replace primary and secondary fuel filters at strict OEM-recommended intervals (often every 15,000-30,000 miles or annually).
Never bypass filters. Use only filters meeting Detroit Diesel specifications (e.g., Fleetguard, Donaldson, Baldwin).
Water Management: Drain the water separator daily (as per standard truck pre-trip procedure). Never allow water to enter the fuel system.
Use Proper Fuel Additives (Optional but Recommended): A trusted anti-gel additive in winter and a year-round lubricity/stabilizer additive can protect the fuel system. Ensure the additive is compatible with Detroit Diesel engines.
Operational Best Practices: Allow the engine to idle for 3-5 minutes before shutdown after a hard run. This helps cool the injectors and prevents coking (carbon buildup) of the nozzle from residual heat.
Professional Diagnostics: If performance issues arise (misfire, smoke), use professional DDEC diagnostics to perform an injector cut-out test or contribution test instead of guessing. Replacing injectors unnecessarily is costly.
