Abstract
A fuel injection pump, preferably for internal combustion engines operating by the Otto method, having a pump work piston driven to reciprocate and rotate simultaneously and defining two mutually independent pump work chambers, is proposed. The first pump work chamber pumps fuel into the combustion chamber of the engine that is in a state immediately prior to ignition, while the second pump work chamber pumps fuel into the combustion chamber operating offset from the other by 360.degree. of crakshaft angle. To this end, two distributor openings are disposed in the jacket face of the pump work piston, offset by 180.degree. from one another and each communicating with a different one of the pump work chambers.
