| Exhaust gas recirculation system |
Note | t
| The engine control unit -J248- activates the exhaust gas recirculation system through theexhaust gas recirculation valve -N18- to the exhaust gas recirculation mechanical valve. |
| t
| The exhaust gas recirculation valve -N18- is located on the solenoid valve block. |
| t
| The mechanical valve for exhaust gas recirculation with conical tappet allows different apertures for different valve positions. |
| t
| Thanks to stepped activation, the valve may be moved to any position. |
| t
| The exhaust gas recirculation begins after the engine has been running at idle for 2 minutes. |
| t
| Restart engine or briefly increase engine speed above 1,500 rpm when longer checks are necessary. Repeat the measurement. |
