EXHAUST GAS RECIRCULATION
(EGR) VALVE

The Exhaust Gas Recirculation (EGR) system is the
device to lower the NOx (oxides of nitrogen) emission
level caused by high combustion temperature.

Because the combustion process of the diesel engine
always needs excessive air, the exhaust gas contains
large amount of NOx.

The EGR valve restricts NOx generation by recirculating
some amount of the exhaust gas into the combustion
chamber to reduce the combustion temperature.

But the recirculated gas results in reduced charging
efficiency of mixture so that the engine performance
drops down. Because of this fact, EGR valve is tuned
to operate in the area where oxidized substances are
generated much.

•

Condition of working the EGR valve

- 100 seconds after starting the engine

- More than 200 RPM

2. Install the micro switch setting device 017 589 08 21 01 in the injection pump.

3. Adjust and fix the lever (6) at 10° ± 1 °

4. Insert the harness into the micro switch setting device 617 589 08 21 01.

5. Install the cam on the injection pump when the both lamps are “on”.

6. Install the screw.

7. At this moment, loosen the clamp and insert the adjusting disc “A” to the lever and check again.

8. If the lamp “A” is “on”, the setting is correct, thus, timing of injection pump is OK.

If the both lamps are “on”, perform the setting as above procedure.
