Note: The EGR system is controlled by the diesel direct injection system control unit using the EGR valve (electropneumatic) to the EGR valve (mechanical).
Note: The mechanical EGR valve with a cone-shaped tappet allows different degrees of opening at different valve strokes.
Note: The valve position is changed by the control system.
Note: Self-locking nuts must be replaced.
