6.3.2. Check and adjustment of installations of the moments of injection of fuel
The moment of injection can be regulated on the removed and installed engine. Further adjustment on the installed engine is described. Check requires the indicator with the corresponding adapter for a vvorachivaniye in TNVD. Adjustment and check have to be made on the cooled-down engine.
Check
|
- Disconnect a negative wire from the battery.
- Remove the air filter with an air inlet sleeve.
- Remove PCV hose from a head of cylinders and release an electrical wiring plait from the holder on the inlet pipeline.
- Turn out bolts of fastening and remove the inlet pipeline.
Bolts of fastening of the inlet pipeline
- Remove the top cover of a gear belt.
- Install the piston of the first cylinder in the provision of VMT (see the Head Dvigateli).
- Remove fuel-supply lines from nozzles and TNVD for what give cap nuts.
|
Do not change a form of pipelines. |
- Turn out a stopper from the TNVD distributor case.
Stopper in the TNVD distributor case
- Screw instead of a stopper an adapter, for example, KM-226-a and the indicator with a range of measurement of 0 ÷ of 3 mm).
- The screw-driver bring the device of increase in speed of cold start of the engine out of working situation.
Deactivation of the device of increase in turns of cold start
- Install the indicator in the provision about 2 mm at a contact with a measuring core of the piston of the pump.
- Turn a bent shaft counterclockwise approximately on the 60th hail. so that the piston of the pump was in the lower point. At the same time the indicator shows the smallest value and does not move any more. In this situation install the indicator on "0". Slightly rotating a bent shaft in different directions, check adjustment. The indicator should not show value less than 0th mm.
- Turn a bent shaft clockwise before combination of tags of VMT and read the instrument on the indicator. Compare indications of the indicator to requirements of Specifications in the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases.
- If requirements of Specifications in the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases are not reached, adjust TNVD.

Adjustment
|
- Turn off nuts of fastening of TNVD and adjusting bolts on his holder.
Nuts of fastening (top) and adjusting bolts (bottom) of TNVD
- Turn TNVD so that to reach demanded by Specifications in the Head of the Power supply system, release and decrease in toxicity of the fulfilled gases of adjusting value (average value from specified in the Head of the Power Supply System Specifications, release and decrease in toxicity of the fulfilled range gases). At the overestimated value turn the pump towards the engine; at underestimated - in the opposite direction.
- Having ended adjustment tighten bolts of fastening of TNVD to a head of cylinders with effort of 25 Nanometers, and fixture of the holder of TNVD - with effort of 45 Nanometers.
- Remove the indicator.
- Tighten the central stopper with a new copper sealing ring with effort of 20 Nanometers.
- Remove the screw-driver from the device of cold start.
- Connect fuel-supply lines to nozzles and TNVD and tighten their cap nuts with effort of 25 Nanometers.
- Clear a shaber of a surface of the inlet pipeline and a head of cylinders of the sealant remains. Put new laying.
- Further installation is made as it should be, the return to an order of dismantle of components. Tighten fixture with the required effort.
