摘要： A fuel injection arrangement for a diesel engine. An overflow passage for high pressure fuel is provided in the engine's fuel injection pump. A solenoid valve is disposed in the overflow passage for controlling the fuel injection amount through its on-off operation. The time when the fuel injection pump starts injecting fuel is detected by an injection start detector. To this injection starting time point is added a target injection period to determine an injection end time. At this injection end time the solenoid valve is opened to discontinue the fuel injection. The target injection period is determined according to operating conditions of the engine. Since this apparatus detects the actual injection start point and controls the injection period on the basis of the result of the detection, the fuel injection amount can be controlled extremely accurately.

摘要： In a diesel engine controlling system having a fuel injection pump, a fuel injection timing adjusting device is controlled by a drive pulse signal whose duty cycle is controlled by a microcomputer. The duty cycle is determined such that a basic duty cycle obtained by using engine rotational speed and injection quantity, is modified or corrected by way of a correction factor and a forecast correction factor. The-first mentioned correction factor comprises an integration component and a proportional component both derived from the difference between a measured fuel injection or ignition timing and a desired or reference fuel injection or ignition timing, which is calculated by using the engine rotational speed and the injection quantity. The forecast correction factor corresponds to a differential value of the basic duty cycle or the desired fuel injection or ignition timing. In order to detect the fuel injection or ignition timing a timing detector is employed, where the state of an output signal from the detector is monitored to prohibit calculation of the difference or error, thereby correcting the basic duty cycle by only the forecast correction factor when the detector is in abnormal condition.

摘要： A fuel injection device for Diesel engines includes a combustion detector comprising a photoelectric transducer and a light path extended through a nozzle body to transmit the light of a combustion flame developed in an engine cylinder to the photoelectric transducer. One end of the light path is opened to an oil sump communicating with a nozzle opening so that only when the nozzle opening is opened for injecting fuel and then a combustion flame is developed, the light of the flame is passed through the light path and reaches the photoelectric transducer thereby generating an electric signal indicative of the actual time of the combustion. The whole or part of the light path may be comprised of optical fibers.

摘要： A signal processing circuit for removing a noise component from a detection signal of a yaw-rate sensor for detecting a yaw rate generated in a motor vehicle. The processing circuit detects the magnitude of variation of the detection signal of the yaw-rate sensor so as to compare the magnitude of the detection signal with a predetermined reference value. In accordance with the comparison result, the processing circuit outputs a limitation detection signal to limit the variation to below the predetermined reference value. Further, when the magnitude of variation of the detection signal exceeds the predetermined reference value, the processing circuit outputs as the limitation detection signal the yaw rate detection signal immediately before the exceeding, and the predetermined reference value is corrected on the basis of the steering angular velocity of the steering wheel of the motor vehicle. This arrangement allows effectively eliminating a spear-like noise from the detection signal of the yaw-rate sensor.

摘要： A gas concentration sensor voltage and current (in both heater on and heater off states) are detected and compared with predetermined thresholds, respectively, by a microcomputer. Based on a combination of the comparison results, the presence or absence of trouble in the system is detected and trouble location in the system is specified. In addition or alternatively, the sensor voltage is compared with thresholds to determine whether it is outside of a normal zone. The voltage may be actually detected or calculated. If the voltage is outside the normal zone, sensor voltage is reduced to zero or restricted to a predetermined limit.
