System of recirculation of the fulfilled gases (EGR) - the general information, check of a state and replacement of components

General information

For the purpose of decrease in issue in the atmosphere of oxides of nitrogen the design of the engine provides branch of part of the fulfilled gases in the inlet pipeline via the EGR valve. Such admixture of the fulfilled gases to air and fuel mix leads to decrease in temperature of its combustion.

The system consists of the EGR valve, the sensor of extent of opening of the EGR valve, the module of management (RSM) and a set of auxiliary information sensors. RSM is programmed so that to provide optimum extent of opening of the EGR valve for any operating conditions of the engine. The special information sensor constantly traces extent of opening of the EGR valve, giving out the corresponding signals on the module of management. RSM compares the entering information of the sensor to the optimum settlement size determined by the data arriving from other information sensors and, in case of need, makes the demanded adjustment of the volume of the fulfilled gases coming to the engine.

CHECK

 PERFORMANCE ORDER

1. For check of serviceability of functioning of the sensor of extent of opening the EGR valve disconnect an electrical wiring from the valve and check existence.
2. Now it is necessary to make functioning check actually of the EGR valve. Start the engine and warm up it up to the normal working temperature. (the fan of the cooling system has to turn on). Now kill the engine and disconnect an electrical wiring from the EGR valve.

3. A wire crossing point connect the positive plug of the battery to the plug No. 4 EGR is riveted. Start the engine and connect the negative plug of the battery to the valve plug No. 6. Stability of turns of the engine has to be broken, up to its full stop, otherwise replace the EGR valve.

4. Further testing of EGR system demands use of special tools and the diagnostic equipment.

Replacement of components of the EGR valve

 PERFORMANCE ORDER

1. Disconnect an electrical wiring from the sensor of extent of opening of the EGR valve.

2. Give two fixing nuts and remove the EGR valve.

3. Smooth out the interfaced surfaces of the valve and its transitional nozzle.
4. Replace sealing laying and install the EGR valve on the regular place. Strongly tighten fixing nuts.
5. Restore initial connection of an electrical wiring.
