Abstract
A fuel injection pump for combustion engines with at least one pump piston which is actuated by a cam mounted on a mechanically operable camshaft is disclosed. The piston stroke is utilized only in part for delivery of the fuel, whereby the fuel feed volume is controllable by changing the effective piston stroke. The fuel injection pump also includes a control element which, in conformity with the number of revolutions of the combustion engine, varies the first derivative of the function of the effective piston stroke in accordance with the cam angle.
