Fuel injectors



The fuel injector based on the signals from the ECM inject fuel into the engine cylinders. Fuel flow depends on the opening time of the injectors, i.e. the width of the voltage pulse to the winding nozzle.

Checking with a stethoscope

PERFORMANCE ORDER

  1. When the engine is idling stethoscope check the operation of nozzles by the presence of clicks. With increasing engine speed clicks should be heard more often.

Ensure that the clicks from the adjacent nozzles are not transferred through the pipeline to the broken nozzle.

  1. In the absence of a stethoscope thumb check the operation of the nozzles by the presence of clicks. If clicks are missing, check the connections on the connectors to the injectors and the output voltage of the control unit.

Measure resistance between connector contacts

PERFORMANCE ORDER

  1. Disconnect the connector from the fuel injector and measure the resistance between the contacts of the connector. Resistance: 15,9 ?� 0,35 ohms at 20 ?� C.
  1. Connect to the fuel injector.
