    摘要: An apparatus for controlling angular position of optical axis of a head lamp assembly for a motor vehicle. An actuator is supplied selectively with the atmospheric pressure and a negative pressure available from an intake conduit of an internal combustion engine thereby to produce corresponding mechanical displacements. A detector for detecting the angular position of the optical axis of the head lamp assembly responds to the mechanical displacements of the actuator to change-over successively the contact states of a plurality of paired electric contacts. A command unit for setting the angular position of the optical axis of the head lamp assembly is provided which includes a plurality of paired electric contacts connected in one-to-one correspondence to the paired contacts of the optical axis position detector. A signal for setting the optical axis of the head lamp assembly is produced in dependence on the contact states of the optical axis position detector.

    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: An optimum control method for internal combustion engines uses the values of an engine control variable, such as engine timing, which are arranged in a map and stored in a memory. During normal operation, the engine is operated in accordance with one of the mapped engine control variable values related to engine operating conditions. During a fuel consumption minimization operation, the mapped engine control variable value is changed by an incremented amount to operate the engine therewith, and the mapped engine control variable value is replaced by the changed engine control variable value, if it is detected that the change by the incremented amount is in a direction to reduce the fuel consumption rate of the engine. This optimum engine control method can compensate for changes in the characteristics of engines caused during the manufacture or caused by changes over time during their operation, thereby ensuring the operation of an engine at a minimum rate of fuel consumption.

    摘要: Disclosed is a fuel injection quantity control system incorporated with a fuel injection pump with a solenoid-operated spill valve wherein a control signal is generated for cutting off a fuel supply to engine cylinders when a rotational phase angle of a drive shaft of the fuel injection pump is coincident with a desired spill phase angle determined in accordance with engine operating conditions. The desired spill phase angle, i.e., the opening timing of the spill valve is controlled in accordance with the rotational variations of the fuel injection pump. The desired spill phase angle is divided by unit angle corresponding to a detection period of rotational angle signals produced in accordance with the rotation of the pump drive shaft, obtaining a quotient and a remainder angle. The remainder angle is converted into a time on the basis of an engine speed. The generation of the control signal basically occurs upon the elapse of the converted time after the count of rotational angle signals is coincident with the quotient. If the engine operating condition varies immediately prior to the coincidence therebetween, the control signal is generated immediately after the coincidence or upon the elapse of a predetermined time period thereafter.
