TECHNIQUE FOR THE DIAGNOSIS OF MALFUNCTIONS IN DIESEL INJECTION SYSTEMS

The majority of the faults studied during this work can be detected and distinguished from one another by measuring peak pressures (either in the pressure chamber of the unit injector or in the injector lines of the distributor injection system) at various speeds. All the data in this paper were taken at no load operating conditions, the most suitable conditions for the diagnosis of the engine while still in the vehicle. The peak pressure in the unit injector pressure chamber can be indirectly measured by mounting a strain gauge on an injector drivetrain component.
