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°of crakshaft angle. To this end, two distributor openings are disposed in the jacket face of the pump work piston, offset by 180°from one another and each communicating with a different one of the pump work chambers.

A fuel injection pump for internal combustion engines, comprising a pump work piston, said pump work piston having a pump piston that periodically pumps fuel and a distributor piston rotatable in a guide bore, said distributor piston having distributor openings discharging at its jacket face, which in accordance with a rotational position of said distributor piston during a pumping stroke of said pump piston simultaneously communicate with inflow lines that discharge, offset from one another by a fixed angle, into said guide bore and lead to various fuel injection locations of said engine, said pump work piston (2), is driven to reciprocate and rotate simultaneously, said distribution piston includes faces (14, 18) axially offset from one another and distributor opens (39, 41) therein, said faces (14, 18) define at least two pump work chambers (15, 16) that are independent of one another and communicate with said distributor openings (39, 41), wherein upon each working stroke of the pump work piston (2), one of the pump work chambers (15, 16) supplies one of the fuel injection locations with fuel, and another of the pump work chambers (15, 16) supplies another of the fuel injection locations with fuel whereby the fuel is directed to one of said injection valves.
