1. Engine Application Scenarios

This injector is designed for heavy-duty diesel engines in demanding applications, including:

• Long-Haul Trucking — Provides reliable fuel delivery for over-the-road (OTR) freight haulers.

• Construction Equipment — Used in loaders, bulldozers, and excavators requiring consistent power.

• Marine & Industrial Engines — Found in generator sets, pumps, and marine propulsion systems.

• Municipal & Vocational Vehicles — Garbage trucks, fire engines, and other heavy-duty service vehicles.

2. Compatible Equipment Models

The 5226425 injector is primarily used in:

Engines:

• Detroit Diesel Series 60 (9G75) — A 12.7L inline-6 turbocharged diesel engine.

• Later Series 60 EGR (2005-2007) models (verify exact fitment with engine serial number).

Truck & Equipment Applications:

• Freightliner Century, Columbia, Argosy

• Western Star 4900, 5700

• Volvo VNL, VNM (with Detroit Diesel Series 60)

• Off-road & Industrial Equipment (e.g., Terex, Komatsu with Detroit Diesel power units)

3. Key Advantages of the 5226425 Injector

✔ Precision Fuel Delivery — Optimizes combustion for better fuel efficiency and lower emissions.
✔ Durability — Built to withstand high-pressure (up to 30,000+ PSI) common-rail diesel systems.
✔ Reduced Carbon Buildup — Advanced spray patterns minimize injector coking and deposits.
✔ Improved Power & Response — Enhances throttle response and torque in heavy-duty conditions.
✔ OEM & Aftermarket Support — Available as genuine Detroit Diesel, Bosch remanufactured, or aftermarket options.

4. Maintenance Considerations

• Symptoms of Failure: Hard starts, misfires, excessive smoke, or poor fuel economy.

• Recommended Service Life: Typically 150,000–250,000 miles, but varies by operating conditions.

• Best Practices: Use ultra-low sulfur diesel (ULSD) and quality fuel filters to extend injector life.
