5.6.2. Check of giving of tension to fuel nozzles

GENERAL INFORMATION

Arrangement of the electric socket (1) of giving of tension to a fuel nozzle and the socket (2) on a fuel nozzle


PERFORMANCE ORDER
1. Disconnect the electric socket from a fuel nozzle of the first cylinder, see rice. An arrangement of the electric socket (1) of giving of tension to a fuel nozzle and the socket (2) on a fuel nozzle.
2. Connect a control light-emitting diode to contacts of the socket (1) (see rice. An arrangement of the electric socket (1) of giving of tension to a fuel nozzle and the socket (2) on a fuel nozzle). At a provorachivaniye of a bent shaft of the engine a starter the light-emitting diode has to blink.
3. Similarly check giving of tension to other fuel nozzles.

The light-emitting diode does not blink on one of cylinders

Arrangement of contacts on the electric socket of giving of tension to a fuel nozzle


PERFORMANCE ORDER
1. Connect a control light-emitting diode to contact No. 1 of the electric socket for giving of tension to a fuel nozzle and the mass of the car, see rice. An arrangement of contacts on the electric socket of giving of tension to a fuel nozzle.
2. Connect contact No. 2 of the electric socket with the mass of the car.
3. Turn a bent shaft of the engine a starter. At the same time the light-emitting diode has to blink. Otherwise check all electric power-supply circuit of fuel nozzles.

The light-emitting diode does not blink only on one or on several cylinders

PERFORMANCE ORDER
1. Check a condition of an electric power-supply circuit of fuel nozzles and define and eliminate the place of break of an electric chain or its short circuit on weight.
2. Check operation of the control unit of the engine.

Check of resistance

Places of connection of an ohmmeter for check of resistance of fuel nozzles



PERFORMANCE ORDER
Consistently disconnect electric sockets from fuel nozzles and, using an ohmmeter, check resistance of fuel nozzles which has to be ranging from 12 to 17 Ohms, see rice. Places of connection of an ohmmeter for check of resistance of fuel nozzles.
Prevention

On the engine which is warmed up up to the normal working temperature, resistance of fuel nozzles increases by 4–6 Ohms.


If resistance of a fuel nozzle differs from demanded, replace a fuel nozzle.
