Description
Fuel control valves: ID, common faults, and diagnostic strategies
Clinton Brett has developed this course to assist technicians adapt a successful diagnostics strategy for Common Rail Diesel fuel control valve faults.
Fuel control valves are vital components in which manufacturers use to operate the modern diesel engine. Previously, mechanical fuel injection pumps controlled the fuel delivery, pressure, and timing of the fuel being injected. Today, the CRD engine computer communicates to individual control valves fitted to pumps, rails, and injectors to control the outcome.
Dependent of the OEM’s objective, the fuel system can vary between manufacturers Bosch, Continental, Delphi, and Denso, therefore it is important to understand each unique design and operation before beginning your diagnostics pathway.
This course will cover:
This course provides an explanation of the function, operation, common faults and diagnostic testing of control valves and how they differentiate in the hydraulic fuel circuit. It will enable technicians to adapt the testing strategies provided or create their own unique method.
Practical content will include accessing scan tool data for fuel rail pressure drops, comparing pressure limiting valve to pressure regulator and an explanation of injector feedback values.
