ISB 6.7L (2007 onwards) – Found in Dodge Ram 2500/3500 (2007+), buses, and medium-duty trucks.
ISL (8.9L)
Used in commercial trucks, buses, and industrial equipment.
QSB (5.9L & 6.7L)
Industrial and marine applications, including generators and construction equipment.
QSL (8.9L)
Industrial, marine, and power generation applications.
Application Scenarios:
On-Highway Trucks: Dodge Ram 2500/3500 (2007+), Freightliner, and other medium-duty trucks.
Off-Highway Equipment: Construction, agricultural, and mining machinery.
Marine Engines: Used in marine propulsion and auxiliary power.
Power Generation: Backup and prime power generators.
Bus & Transit: School buses, city transit buses, and coach applications.
The Cummins fuel injector (Part #4928171) is a high-performance High-Pressure Common Rail (HPCR) injector designed for precision fuel delivery in modern diesel engines. Below are its key characteristics:
1. High-Pressure Common Rail (HPCR) System
Operates at extremely high fuel pressures (up to 30,000+ psi) for optimal atomization.
Ensures precise fuel metering for improved combustion efficiency and reduced emissions.
2. Precision Engineering
Electro-hydraulic design for fast response times.
Multi-hole nozzle for fine fuel spray patterns, enhancing combustion.
Tight tolerances for durability under high-pressure conditions.
3. Compatibility & Applications
Used in Cummins ISB 5.9L/6.7L, ISL 8.9L, QSB, and QSL engines.
Found in Dodge Ram (2007+), commercial trucks, buses, marine, and industrial equipment.
4. Performance Benefits
Improved fuel economy due to efficient combustion.
Lower emissions (meets EPA standards) by reducing unburned fuel.
Smooth engine operation with reduced noise and vibration.
