EGR Components

EGR Components

• Exhaust Gas Recirculation (EGR) is controlled by the engine control module (J623) and the engine control module 2 (J624) via the EGR vacuum regulator solenoid valve (N18) (electro-pneumatic) and valve 2 for EGR (N213) (electro-pneumatic) to the mechanical EGR valves.

• The mechanical EGR valve with a cone-shaped valve plunger makes different opening diameters possible at different valve lifts.

• The components illustrated here are for cylinder bank 2. They are a mirror image of the components for cylinder bank 1.
