摘要： A method and apparatus for controlling a Diesel engine by limiting the amount of fuel to be admitted to the engine in dependence on engine speed and on the air mass flow rate. The invention provides a primary set of stored data interrelating these variables. The primary data set is used to generate a set-point value for the position of a movable stop member which limits the mechanical travel of the fuel control rack in the fuel injection pump; the control rack is also subject to the action of a mechanical speed governor. Additional corrections of the maximum amount of fuel are made on the basis of air temperature and fuel temperature. Still further refinements include taking into account exhaust gas temperature and engine starting conditions. The final corrected set-point signal is then compared with the output from a position indicator which is attached to the stop member. A servo-controlled element corrects the position of the stop member until the error indications are minimized in a closed loop, feedback control circuit.

摘要： Disclosed a regulating device for a fuel volume adjuster of a self-igniting internal combustion engine. In order to damp jerking movements resulting at different power transmissions, a signal corresponding to the actual rotary speed of the engine is fed back into an electronic regulating circuit. Preferably, the feedback path includes a phase shifter. It is essential that the regulating action of the rotary speed be not delayed by the phase turning shifter. For this purpose, the electronic regulating circuit includes a PI stage and the fed back signal is applied to the regulating circuit only after its I-constituent has become effective.

摘要： An rpm-governing system for an internal combustion engine with auto-ignition is proposed, in which the fuel quantity to be injected at least in the event of idling is subject to the influence of an electromagnetic final control element, in which the control unit for forming the final control element trigger signal includes a regulator having PID behavior and in which the regulation signal is formed in accordance with the actual rpm/set-point rpm deviation. This rpm-governing system has an increase in rpm set-point value, with a retarded drop, this increase in set-point being made to follow up the increase in actual value. The PID regulator furthermore has a non-linear and preferably rpm-dependent P component. The signal end stage includes a pulse length modulator, the output signal of which triggers an electromagnetic final control element while there is a simultaneous current regulating action.

摘要： There is described a method and apparatus for use in association with the fuel injection pumps of Diesel engines to time the moment of injection. The method and apparatus described relate to a closed-loop control system which engages a final control element in the fuel injection pump that changes the injection timing, i.e. the onset of fuel delivery and, hence, the onset of fuel injection. The controlled variable is the moment of fuel injection, detected by suitable means placed near the injection valves. A set-point value for this instant is derived on the basis of stored data which correlate the correct moment of injection as a function of engine speed with various optimum conditions, for example, low fuel consumption, low smoke generation, low noise, etc. The selection of the proper characteristic curve from the stored data set is made automatically or manually. The time of occurrence of the actual value pulse and the time of the set-point pulse are compared, for example, by converting the former to analog form, and the resulting control deviation is obtained as a preferably digital counter content which is used to engage the final control element to reduce the deviation.

摘要： For a speed governing system for an internal combustion engine with self-ignition, which includes an electromagnetic final control element for influencing the injection quantity and a control unit having a governor for controlling the final control element, provisions are proposed which give the governor a high dynamic amplification in the range of a drop in the engine rpm, a dynamic amplification that drops from a higher value to a lower value in the range of a sudden drop of engine speed, that is, an rpm undercutting, and a flattened governor characteristic in the vicinity of the ends of the control range. A governor of this kind reacts very flexibly to changes in rpm and in particular does not enter a saturated state, and it adjusts to a new control state without disruptive reacceleration phenomena. A governor of this kind is particularly well suited for motor vehicles having a Diesel engine with a relatively large number of cylinders.

摘要： The ratio of the inductance of a measuring coil to that of a reference coil is formed by an operational amplifier. Specifically, the measuring coil is connected between the output and the inverting input of the operational amplifier, the reference coil being connected to the inverting input. An AC voltage having substantially symmetrical half waves is applied to the reference coil. The AC voltage is a triangular voltage generated by two additional operational amplifiers. An emitter-follower connected to the output furnishing the triangular voltage decreases the load on the operational amplifiers and therefore allows the connection of a multiplicity of computing stages to the one source of triangular voltage. Additional operational amplifier stages, in conjunction with diodes, constitute a full wave rectifier and filter for the output of the operational amplifier furnishing the ratio signal.

摘要： A control system for a fuel pump, particularly for a solenoid-valve-controlled fuel pump in the case of a self-ignitable internal-combustion engine, in which at least one pulse transmitter is mounted on the crankshaft and/or on the camshaft. The generated pulse sequences include at least several reference pulses for establishing the beginning of fuel injection, as well as speed pulses for detecting the average and the instantaneous rotational speeds. A trial activation takes place to detect into which cylinder the fuel must be injected. Based on the reaction of the fuel injection system and/or of the internal-combustion engine, it is detected whether fuel was injected into the proper cylinder.

摘要： The invention relates to a method and arrangement for preparing a fuel-metering signal M for a diesel engine starting with measured variables such as accelerator pedal position, rotational speed, lambda, exhaust gas temperature or torque. A fuel quantity request MW is pregiven in dependence upon the position of the accelerator pedal. This quantity request MW is supplied to a minimum selector together with a second signal. The output signal M of the minimum selector, in turn, determines the metered fuel. The second signal derives from a precontrol characteristic field 50 in dependence upon the speed. The output signal of the precontrol characteristic field MV is influenced by the controller output signal MR in specific operating conditions.
