Engine codes BKC, BRU, BXE and BXF

Note

The exhaust gas recirculation system is activated by the diesel

direct injection system control unit -J248- via exhaust gas re‐

circulation valve -N18- (electric-pneumatic) to the exhaust gas

recirculation valve (mechanical).

The electro-pneumatic exhaust gas recirculation valve -N18-

is located in the solenoid valve block.

The cone-shaped plunger in the mechanical exhaust gas re‐

circulation valve ensures that various cross sectional openings

are possible at different plunger lifts.

Pulsed control enables every conceivable valve position.

Renew self-locking nuts.
