摘要： A fuel injection pump designed to deliver an amount of fuel divided into a pilot and a main injection volume, including a surface of a pump plunger which is guided within a pump cylinder, apart from two recesses limited by an inclined control edge, a first horizontal control edge is formed by a frontal shoulder; and on a side opposite the shoulder, it has a fully enclosed transverse groove with a second and third control edge. Two control apertures and an annular groove above them in the wall of the pump cylinder effect the control, in conjunction with the aforementioned control edges, of the precisely determinable pilot injection and, after a delivery interval, determined by the difference (b-a) between the width (b) of the transverse groove and the distance of the annular groove to the control aperture, the subsequent main injection. For the purpose of controlling an exact and largely speed-independent start of delivery of both the pilot and the main injection, the control apertures can be equipped with a straight limiting edge on the pump chamber side.

摘要： A process for controlling and measuring the movement of an armature of an electromagnetic switching member with an excitation coil is proposed, which has the following steps: a current (i) or a voltage (u1) is applied to the excitation winding (3) in order to move the armature into a first actuatable position; before the start of the movement of the armature, the current or the voltage is raised above a value at which the armature remains in the actuated position, and before termination of the movement of the armature the current or the voltage is reduced to a defined value, which suffices to hold the armature in the actuated position; finally, the temporal variations in the current or the voltage are measured after setting of the defined value, for the purpose of recognizing the termination of the armature movement. With the aid of this process, it is possible for the movement of the armature, for example of a solenoid valve for a fuel injection device of an internal combustion engine, to be very precisely monitored, so that the injection instant and injection period can be optimally set.

摘要： A method and apparatus for controlling the flow of fuel for a gasoline or diesel gasoline engine controls a solenoid valve for actuating the fuel pump. A pump piston is driven by the camshaft and, in turn, pressurizes the fuel for delivery to the individual cylinders. Based on the operation of the solenoid valve, the beginning of the injection of fuel and the end of the injection of fuel are established Based upon spaced angular markings on the camshaft, a control unit determines the trigger signals for actuating the solenoid valve. To calculate the trigger signals, the markings on the camshaft are counted and interpolated therebetween over time. The interpolation is based on the instantaneous rotational speed N of the camshaft, which is sensed immediately before performing the interpolation.

摘要： A fuel injection pump for internal combustion engines is proposed, in which to attain particularly quiet operation of an engine that is operated with direct injection, the fuel delivery is subdivided into a preinjection and a main injection; this injection is attained by annular groove, coinciding with one another, on the pump piston and pump cylinder, and a connecting groove connecting the coinciding annular grooves with a relief opening. After a partial stroke in the region of coincidence of the annular grooves with one another, the communication with the relief opening is interrupted again. The preinjection quantity can be kept particularly small here, with a short interval between the preinjection and the main injection; in combination with a two-spring-holder injection valve, this particularly small preinjection quantity can be kept constant to a great extent even at varying engine speeds, to attain an optimal reduction in combustion noise at various engine speeds.

摘要： A fuel injection system is proposed, having a valve each for the pre-injection quantity and for the main injection quantity, each of the valves having plural injection ports. The injection ports for the pre-injection quantity are smaller than those for the main injection quantity. Furthermore, the injection streams of the pre-injection quantity form a cone angle which is smaller than the cone angle of the main injection streams. By means of the two injection pumps it becomes possible to regulate exactly and indepedently the amount of injection as well as the injection time of the pre-injection quantity and of the main injection quantity.

摘要： A fuel injection pump is proposed in which over a first portion of the supply stroke of the pump piston fuel for the main injection is pumped via a distributor line and a distributor groove into one at a time of a plurality of fuel injection lines. In a second, remaining portion of the pump piston supply stroke, on the same cam flank, fuel is then pre-stored in a reservoir, controlled by a first electrically controlled valve and a second electrically controlled valve and by one of a plurality of longitudinal control grooves, which fuel subsequently, before the beginning of the next main injection determined by the closure of the first electrically controlled valve, is pumped via a second distributor line into the next succeeding injection line.
