Fuel nozzles

Fuel nozzles on the basis of signals from the ESM block inject fuel into engine cylinders. The amount of submitted fuel depends on time of opening of nozzles, i.e. from width of an impulse of tension submitted on a nozzle winding.

Check with stethoscope use


    At operation of the engine idling a stethoscope check work of nozzles on existence of clicks. At increase in frequency of rotation of a cranked shaft clicks should be distributed to a thicket.

Guarantee, that clicks from an adjacent nozzle were not transferred on the highway to an idle nozzle.

    In the absence of a stethoscope a finger of a hand check work of nozzles on existence of clicks. If clicks are absent, check reliability of connection of sockets to nozzles and target tension of the control unit.

Resistance measurement between socket contacts


    Disconnect the socket from a fuel nozzle and measure resistance between socket contacts. Resistance: 15,9±0,35 Ohm at 20°C.
    Connect the socket to a fuel nozzle.
