    Failure Report

    Uploaded by

    Crisdianto
    This failure report summarizes an issue with a CLG922E engine with serial number CL000151 that had 27.7 hours of use. The customer in Brazil reported an error code 3741, which corresponds to high pressure in the fuel system. Upon inspection, the technician found contamination in the diesel fuel lines that was blocking fuel flow and causing the fuel pump actuator to fail due to low resistance. The root cause was determined to be contamination in the fuel system. The technician cleaned the fuel lines and replaced the fuel filter and actuator, resolving the fault.

    complain
    故障检查描述 Failure Inspect Description：When you turn on the machine and works
    with a greater acceleration than 1000rpm the engine fault code 3741 appears in muni
    tor indicating high pressure in the fuel system, the INSITE tool Cummins was used
    to install the tool on the machine gives us a step step towards the solution
    fails, the resistance of the actuator of the fuel pump was verified and it was
    below the required parameters found that the lines of high and low fuel pressure
    were blocked owing to the diesel particulate contamination, thus concluded that
    the actuator It failed due to the particles of contamination impeding the system
    from working properly

    故障排查（包含数据测量）Inspect Process (test information)：


    1° step: Inspect in Engine Wiring Harness (The tests were all within the parameters)
    2° step: Inspect Rail Fuel Pressure Sensor (The tests were all within the parameters)
    3° step Inspect in Fuel Rail Supply Line (High Pressure) (cleaning was made in the fuel line)

    4 step: Inspect in Fuel Pressure Relief (cleaning was made in the fuel line)
    5 Step: Fuel Inlet Restriction (Made the test and found no restriction)
    6 Step: Inspect and clean the lines of high pressure
    6 Step: Inspect Fuel Filter (They were replaced all the fuel filters)
    7 Step: Inspect the actuator of fuel transfer pump (According to the literature Cummins the
    electric resistance value of the actuator is 1 to 5 OMHS so I tested and found OMHS less than 1 which
    indicates the electrical component failure)

    故障原因与判断 Rooot Cause：The root cause of the failure was the contamination of fuel that caused the
    low resistance of the transfer pump actuator because a low resistance to the electrical current is greater
    causing it to have a fuel pressure reading error, it was done cleaning the system and the actuator was
    replaced and the fault has been resolved
