Fleet HPCR Fuel System Training
Pinpoint Issues in High-Pressure Common Rail Systems
High-Pressure Common Rail (HPCR) fuel systems are sensitive and expensive. This training helps techs identify root causes and avoid parts-swapping. It covers electronic controls, sensors, actuators, and failure patterns across modern engines.
Topics Covered
- HPCR system theory (rail pressure, injectors, ECM)
- Sensor diagnostics and signal testing
- Fuel quantity control valves and suction control
- Return flow tests and pressure tests
- Common rail failures by brand (Cummins, Volvo, etc.)
Outcomes
- Reduce guesswork and unnecessary injector swaps.
- Improve repair accuracy and first-time fix rate.
- Ensure compliance with fuel-related emissions.
