Abstract: In a fuel injection pump, in order to prolong the duration of fuel injection during each pressure stroke of the pump piston in the idling or low load rpm range, there is provided a bypass channel extending from the pump work chamber for continuously discharging part of the fuel displaced by the pump piston. Said bypass channel contains a valve means which closes the bypass channel when the engine rpm exceeds the idling or low load rpm range.

Abstract: In a fuel injection pump the quantities delivered during each pressure stroke thereof are varied by opening a bypass channel at a predetermined moment by means of a regulator shuttle driven from a constant abutment by hydraulic pressure generated by pump means operating synchronously with the main piston of the fuel injection pump. Said predetermined moment is variable by turning said regulator shuttle. The moment fuel delivery starts during each pressure stroke may be changed without affecting the delivered fuel quantities by means delaying to a lesser or greater extent the buildup of said hydraulic pressure.

Abstract: A fuel injection system having a reciprocating control member driven in synchronism with the injection pump for opening a fuel and interrupting the injection process. The control member, during its return stroke, drives the fluid through a controllable throttle channel to create a fluid abutment,'''' i.e., it does not return to the initial position. A second bypass is provided subject to control by the control member as well as by a slide valve; also synchronous with the main pump, the characteristic feature being the coordination of the control member with the slide valve in dependence on the variable position of the fluid abutment.

Abstract: A fuel injection pump wherein the fuel distributing piston moves angularly and axially in synchronism with rotational speed of the engine and cooperates with an adjusting member which determines the beginning or termination of fuel injection into the cylinders. The adjusting member forms part of a transducer which is installed directly in the housing of the fuel injection pump and further includes an electromagnet having a rotary armature which is operatively connected with the adjusting member to position the latter in dependency on the intensity of signals which energize the electromagnet and are furnished by an electronic control circuit. The intensity of such signals, and hence the position of the armature, is a function of rotational speed of the engine, position of the gas pedal, and other factors.

Abstract: A fuel injection system having a reciprocating control member driven in synchronism with the injection pump for opening a fuel bypass and interrupting the injection process. The control member, during its return stroke, drives the fluid through a controllable throttle channel to create a ''''fluid abutment,'''' i.e., it does not return to the initial position. A second bypass is provided subject to control by the control member as well as by a slide valve; also synchronous with the main pump, the characteristic feature being the coordination of the control member with the slide valve in dependence on the variable position of the fluid abutment and a throttling restriction provided in the second bypass.
