Common Rail Diesel System Diagnosis (Two Days)

Objectives of this training course:

• Understanding hydraulic and electrical systems
• Implication of faults on vehicle behavior
• Emissions systems
• Diagnostic tips and hints
• Interpreting scan tool and oscilloscope data

Course topics include:

• Diesel operating and hydraulic principles and combustion processes
• Solenoid and Piezo Injectors: design variations and functionality
• Variable-geometry turbochargers
• Common rail specific sensor and actuator functions
• Engine management and emission control systems
• Modern emissions reduction technologies, including:

• DPF - Diesel Particulate Filters
• SCR - Selective Catalytic Reduction (Ad-Blue)

Practical sessions are undertaken to further enhance trainee understanding and diagnostic skills, these sessions include:

• Fault diagnosis and system testing using scan tools
• High and low fuel pressure measurements
• Injector back-flow measurement using system-specific tools
• Oscilloscope electrical testing of sensors and actuators

This course is recommended for all general workshop technicians that perform repair work on vehicles equipped with common rail diesel systems.
