    摘要: In a turbocharged diesel engine (10), the charging pressure P.sub.La is adjusted to run the engine (10) with an empirically determined optimum fuel consumption. A charging pressure feedback signal P.sub.La is fed to a regulating device (40) which receives various operating parameters, including ME.sub.d which represents the power output. A characteristic field in a memory zone (50) in the regulating device (40) determines a control variable (TV) which operates a turbine by-pass valve (22) via an electro-pneumatic converter (28) and a penumatic (vacuum) actuator (26). The characteristic field is such that the charging presssure P.sub.La is reduced in the part load range (cruising speed) to improve fuel consumption.

    摘要: A fuel injection system for an internal combustion engine whose air induction tube contains an air flow rate measuring member with non-linear operating characteristics, coupled to a potentiometric transducer which produces the electric command variable for a follower control loop. A control amplifier drives a servomotor which sets the metering slide of a fuel metering valve assembly. The servomotor shaft is coupled to a second potentiometric transducer whose output is compared with the command variable in a bridge circuit connected to the input of the control amplifier. The mechanical link between the servomotor and the fuel metering slide has a non-linearity similar to that of the air flow rate measuring member.

    摘要: A method and apparatus for improving the acceleration behavior of a self-igniting internal combustion engine driven with an exhaust turbocharger by displacing the onset of injection during the acceleration phase toward "early", and a combustion chamber pressure is attained, which at least in part compensates for reduction in engine power caused by sluggishness of the turbocharger and a resultant smaller cylinder charge. Further increase in power is attained by means of an increase in the fuel component made possible by the adjustment of injection onset without exceeding the smoke limit of combustion. Apparatus are furthermore proposed for performing the method according to the invention, in which with the aid of an acceleration signal obtained by hydraulic or electric elements an adjustment toward "early" is effected in a hydraulically functioning injection adjustment device.

    摘要: A fuel metering control loop which includes an exhaust gas sensor and an integrating controller. In order to operate the system at an air number which may differ from the most stable operating point of the oxygen sensor, the output signal from the controller is deliberately changed so as to override the command signals from the oxygen sensor. In particular, the output signal undergoes a step-change toward a higher or lower value at the times of reversal of sensor potential. Thus, the average value of the air number which the controller effectively maintains is different from the nominal value which would be obtained with direct sensor control. In another embodiment, the ongoing integration process is continued for some time beyond the sensor signal reversal.

The amplifier also receives a feedback signal from a second transducer which monitors the position of a servo-motor controlling the quantity of fuel metered out to the engine. The feedback loop maintains a desired fuel-air ratio and includes provision for calibration and adjustment.

    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: A control system for the fuel injection mechanism of an internal combustion engine, especially a Diesel engine. In order to adapt the fuel admitted to the engine to exact requirements, a correction is made on the basis of air mass flow rate and fuel temperature. The air mass flow rate is deduced from signals generated by an air temperature sensor and an air pressure sensor while the fuel temperature is taken by a fuel temperature sensor. The two temperature signals are applied to a bridge circuit which feeds a differential amplifier whose output is mixed with the pressure signal. The composite mixed signal is applied to a servo-mechanism to limit the excursion of the fuel control rack of the fuel injection pump. Status indicators generate feedback signals for comparison with set-point signals to provide closed-loop control.
