Part Number: RFE4E00001 (This is the current, active part number for a remanufactured injector).
Application: Detroit Diesel Series 60 (12.7L and 14L) engines. It is critical to verify it matches your specific engine model and horsepower rating.
Injector Type: Electronic Unit Injector (EUI).
Older/Obsolete DD Part Numbers: 23519167, 23520736, 23521294, etc. The RFE4E00001 supersedes many older numbers.
Cummins/Commercial Fleet Numbers: 5307663, R5307663 (Cummins reman number).
Aftermarket Equivalents: Many reputable manufacturers (like Bosch, LuK, SSL/Diesel Pro) have their own part numbers for equivalent reman injectors (e.g., SSL/Diesel Pro # FCR60-1401-R).
CAC (Customer Acknowledgement Code) Injectors: This part may also be associated with CAC numbers related to specific emissions-related campaigns. Check with a dealer to see if your engine is part of any active program
Here is a concise breakdown of the Detroit Diesel RFE4E00001 fuel injector.
1. Structural Characteristics & Technical Advantages
Structure: This is an Electronic Unit Injector (EUI). It's a compact, high-pressure, camshaft-driven system where the pumping element and solenoid-controlled nozzle are integrated into a single unit per cylinder.
Key Components:
Solenoid Valve: Precisely controls injection timing and duration via ECM signals.
Plunger & Barrel: Camshaft-driven to generate extremely high injection pressure (up to ~30,000 psi).
Nozzle: A multi-orifice nozzle atomizes fuel directly into the combustion chamber.
Technical Advantages:
High Pressure & Efficiency: Creates very high pressure independent of engine speed, leading to superior fuel atomization, cleaner combustion, and better fuel economy.
Precise Electronic Control: Enables precise control over injection timing, rate, and quantity for optimized performance and lower emissions.
Compact Design: All-in-one design eliminates high-pressure lines, reducing potential leak points and simplifying the cylinder head layout.
2. Main Application Scenarios & Equipment
This injector is used almost exclusively in the Detroit Diesel Series 60 engine, a legendary heavy-duty diesel.
Primary Applications:
Line-Haul Trucks: The dominant application (e.g., Freightliner, Western Star, Kenworth, Peterbilt with Series 60).
Vocational Vehicles: Dump trucks, refuse haulers, cement mixers.
Stationary Power: Generator sets and industrial power units.
Some Marine Applications.
Key Equipment: Found in engines spanning the late 1990s through the 2010s, particularly in models meeting EPA emissions standards up through EPA 04/EPA 07.
3. OEM Cross-Reference Numbers
The RFE4E00001 is the current genuine Detroit Diesel remanufactured part number. It supersedes numerous older numbers. Key OEM references include:
Detroit Diesel (Primary): RFE4E00001 (Current Reman)
Common Superseded DD #s: 23519167, 23520736, 23521294, 23518404
Cummins/Commercial #: R5307663 (Reman), 5307663 (New)
Common Aftermarket/Supplier #: FCR60-1401-R (a widely recognized equivalent reman number).
4. Daily Maintenance Suggestions
Preventive maintenance is key to injector longevity.
Fuel Quality is #1: Use high-quality, clean, ultra-low-sulfur diesel (ULSD). Contaminated or poor-quality fuel is the leading cause of injector wear and failure.
Filter Maintenance: Change fuel filters at strict, regular intervals (as per manual, typically every 15,000-30,000 miles). Never neglect water separators.
Use Proper Lubricity: Ensure the fuel has adequate lubricity additives, as ULSD can be "dry" and increase wear on the injector's precision plunger.
Monitor Performance: Pay attention to early warning signs: hard starting, excessive black or white smoke, loss of power, rough idle, or increased fuel consumption. Address these immediately.
Operate Engine Properly: Allow the engine to reach normal operating temperature under moderate load regularly to prevent carbon buildup and wet-stacking.
Professional Service: When injector service is needed, ensure programming (trim code calibration) is performed by a technician with the correct Detroit Diesel Diagnostic Link (DDDL) software.
