Fuel control valves are critical components in the operation of modern diesel engines.
In this course, Clinton Brett explains how to develop an effective diagnostic strategy for common rail diesel fuel control valve faults.
In earlier systems, mechanical fuel injection pumps controlled fuel delivery, pressure, and timing. In modern common rail diesel (CRD) systems, the engine control unit communicates with individual control valves fitted to pumps, rails, and injectors to manage fuel delivery and pressure.
Depending on the manufacturer’s design, fuel systems vary across Bosch, Continental, Delphi, and Denso. Understanding these differences is essential before beginning the diagnostic process.
Understand how fuel control valves influence pressure and flow to avoid unnecessary component replacement.
For injector-specific control and diagnostics, see our course on Fuel Control Valves: Injectors.
This course covers:
• Identification of fuel control valves
• Function and operation of control valves within the hydraulic fuel circuit
• Common faults and failure patterns
• Diagnostic testing procedures
Fuel rails:
• Fuel pressure limiting valves
• Fuel pressure control valves
• Flow dampers / differential valves (agricultural, earthmoving, heavy plant and machinery)
Fuel pumps:
• Inlet metering valves
• Fuel control valves
• Fuel metering valves
• Suction control valves
• Pressure control valves
Inclusions:
Downloadable 30 page training booklet & professional development certificate.
Short series of questions to consolidate learning, along with a published technical articles that expands on the recorded content.
Course access for one week - an email reminder will be sent one day prior to course expiry.
