FUEL NOZZLE

Fuel nozzle, it is central installed in the case of throttles is the electromagnetic valve which gives a certain dose of fuel for the corresponding mode of loading of the engine. This dose of fuel in the form of small sprayed particles goes directly to an inlet collector. At the same time the nozzle is under constant pressure of fuel which is provided with the fuel pump and is supported by pressure regulator.

Removal and installation

PERFORMANCE ORDER
1. Take off pressure in fuel system and remove a weight wire from the accumulator.
2. Weaken a collar and remove an air inlet pipe from a throttle case casing. Disconnect hoses, unscrew screws and remove the top casing of the case of a throttle.
3. Release clamps and disconnect the electric socket from a fuel nozzle.
4. Unscrew the screw of fastening of the plate holding a fuel nozzle.
5. Remove a plate of fastening of a fuel nozzle.
6. Take a fuel nozzle from the case of throttles together with sealing rings (are specified by shooters).
7. Installation is made in the sequence, the return to removal. At the same time on a fuel nozzle it is necessary to establish new sealing rings.

PRESSURE REGULATOR


Prevention

The regulator of pressure is a component of the top section of the case of throttles.


Removal and installation

PERFORMANCE ORDER
1. Take off pressure in fuel system and remove a weight wire from the accumulator.
2. Weaken a collar and disconnect an air inlet pipe from the top casing of throttles. Disconnect hoses, unscrew screws and remove the top casing of the case of throttles.
3. Using a marker, apply combination tags on a cover of the regulator and the case of throttles. Then unscrew screws (are specified by shooters) and uncover pressure regulator.
4. Uncover (4), then take a nest of a spring (3), a spring (2) and a diaphragm (1). Check a condition of a diaphragm and, if necessary, replace.
5. Installation is made in the sequence, the return to removal.

ENGINE OF MANAGEMENT OF IDLING TURNS

Removal and installation

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. For improvement of access to the engine weaken a collar and disconnect an air inlet pipe from the top casing of a throttle. Disconnect hoses, unscrew screws and remove the top casing of the case of throttles.
3. Weaken clamps and disconnect electric sockets from the step engine operating turns of idling which is established in a forward part of the case of throttles.
4. Unscrew screws and remove the engine of management of idling turns (it is specified by an arrow).
5. Installation is made in the sequence, the return to removal. At the same time it is necessary to establish a new sealing ring. Also check that the end face of a plunger does not come more than to 28 mm from the engine. If it is necessary, moving a plunger, establish its correct vystupaniye.

THROTTLE POTENTIOMETER

Removal and installation

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator. Weaken clamps and remove the electric socket from a potentiometer of a throttle which is established on the left side of the case of throttles.
2. Unscrew screws and remove a potentiometer.
3. Before installation apply the means interfering their unscrewing on a carving of bolts, establish a potentiometer and fix by bolts, having tightened them the required moment.

SENSOR OF TEMPERATURE OF COOLING LIQUID


The sensor of temperature of cooling liquid is installed in a back part of an inlet collector.

THE SENSOR OF ABSOLUTE PRESSURE IN THE INLET COLLECTOR

The sensor of absolute pressure in an inlet collector is installed on a partition of a motor compartment to the left of the case of throttles.

Removal

PERFORMANCE ORDER
