Check of gates of injection (injectors)

Gates of injection inject fuel falteringly, i.e. for one turn of the crankshaft a half of absorption of fuel necessary for one step is injected. Thus the gate injects fuel in the form of a cone, and after dispersion is densely closed. Faulty gates of injection cause engine further work after switching off of ignition and interruptions in operation of the engine.

Work check


    To leave the engine to idle.
    To check each gate on the working engine by means of a stethoscope, whether it clicks. These clicks are caused by opening and gate closing. If the stethoscope is not present, it is possible to check operation of the gate as a screw-driver or a finger. If noise from work is absent or has unusual character, it is necessary to check shtekerny connection, a signal from a monitor (it is carried out in a workshop) or resistance.

Resistance check


    To switch off ignition. To disconnect tips of gates of injection. To measure by an ohmmeter resistance of all gates of injection on sockets.

Demanded value: (all engines) 12-16 Ohm.

    If value does not correspond demanded, it is necessary to replace the gate of injection.
    The special tools which are available in firm masterful MAZDAS are necessary for check of a stream of injection and tightness of the gate.
