Abstract
A fuel injection apparatus comprising a radial piston distributor pump is described, which has first pump pistons in a first radial plane and second pump pistons in a second radial plane the pump pistons being diametrically opposite one another and those of the first radial plane being offset in the rotational direction from those of the second radial plane, and the pump pistons of both radial planes being driven by a common cam ring. The fuel positively displaced by the pump pistons is delivered via a common pressure line to a first distributor opening and a second distributor opening, which are disposed spaced apart by 135.degree. from one another on the jacket face of the distributor of the radial piston pump and which supply fuel injection lines with a pre-injection quantity and a main injection quantity of fuel.
