| Exhaust gas recirculation system, engine code AXW, BLX, BLR, BVY |
Note | t
| Under certain operating conditions, exhaust gas is fed into the intake air via the exhaust gas recirculation valve. By means of this mixture, a lowering of the combustion temperature and consequently an improvement of the exhaust gas composition is achieved. |
| t
| The exhaust gas recirculation valve is activated by the engine control unit. |
| t
| Pulsed actuation makes it possible to obtain any required valve position. |
| t
| The exhaust gas recirculation potentiometer signals the current position of the exhaust gas recirculation valve to the engine control unit. The valve and the potentiometer are integrated in a single component. |
| t
| If the exhaust gas recirculation valve is blocked in the open position, this is noticeable due to poor idling characteristics. |
