    摘要： A display for a copying apparatus includes a display element for indicating the operating conditions of the copying apparatus. The display has a number of detectors for detecting each of a group of operating conditions and an energizer for energizing the display element in response to the outputs from the detectors. The display element operates with a predetermined on-period and a predetermined off-period for each corresponding detector. The display is capable of displaying a group of operating conditions by a single display element through a group of display conditions such as being on, being off and blinking.

    摘要： An ignition timing control method for an internal combustion engine, which controls the ignition timing, on the basis of a basic ignition timing value determined as a function of operating parameters of the engine. When a detected parameter value indicative of engine temperature is lower than a predetermined value, a correction variable for the basic ignition timing value is determined based upon detected parameter values indicative of engine temperature and engine load magnitude, to correct the basic ignition timing value thereby. Ignition of the mixture is effected at a timing according to the corrected basic ignition timing value. Preferably, when detected engine rotational speed is lower than a predetermined value lower than the engine idling speed or when it is higher than a predetermined high rotational speed value, the correction of the basic ignition timing value by the correction variable is prohibited.

    摘要： An air-fuel ratio control method for an internal combustion engine, wherein when the engine is in a feedback control region, a value of concentration of oxygen detected by the O.sub.2 sensor is compared with a predetermined reference value, and the air-fuel ratio of a mixture being supplied to the engine is controlled to a desired value in a feedback manner responsive to the comparison result. When the engine is in a predetermined high load operating region, the feedback control is interrrupted and an amount of fuel to be supplied to the engine is increased by a predetermined amount to thereby enrich the air-fuel ratio. The predetermined amount is increased when the engine is in the predetermined high load operating region and at the same time the detected oxygen concentration indicates that the air-fuel ratio is on a lean side with respect to the desired value.

    摘要： A fuel supply control system for an internal combustion engine having a throttle body, and a fuel injection valve arranged in an intake manifold upstream of the throttle body for supplying fuel to all cylinders. An air throttle valve has a valve body having a notched opening formed therein and disposed to be opposite the nozzle of the fuel injection valve to increase the flow speed of intake air in the vicinity of the nozzle when the air throttle valve is fully closed. An electronic control unit controls the fuel injection valve in response to operating conditions of the engine. The electronic control unit causes the air throttle valve to be fully closed when a predetermined low rotation-speed operating condition of the engine, in which at least the rotational speed of the engine is lower than a predetermined value, is satisfied. The predetermined value of the rotational speed of the engine is set such that the lower the atmospheric pressure the smaller the predetermined value.
