Abstract
The apparatus has a fuel injection pump with two partial suction chambers separate from one another. Fuel is delivered to the first partial suction chamber by a second feed pump. A feed pump is associated with the second partial suction chamber, and a reversing valve is disposed between the feed pump and the second partial suction chamber. To inactivate the cylinders of the engine that are associated with the second partial suction chamber, the reversing valve is reversible into a deactivation position, in which the intake side of the feed pump communicates with the second partial suction chamber and the pressure side communicates with the fuel supply tank. Fuel is thus evacuated from the second partial suction chamber by the second feed pump, so that fast inactivation of the associated cylinders is attained.
