摘要： An automotive fuel injection system for detecting as quickly as possible the occurrence of acceleration without employing a throttle sensor to thereby perform an asynchronous fuel injection for the purpose of maintaining the air-to-fuel ratio of the combustible air-fuel mixture at an optimum value during the acceleration of the automotive engine. The automotive fuel injection system comprises a device for comparing the pressure inside the fuel intake system with an average value of the pressures inside the fuel intake system. When the pressure prevailing in the fuel intake system deviates by a predetermined quantity from the average pressure inside the fuel intake system, acceleration is deemed as actually occurring in the automotive engine and, hence, asynchronous fuel injection is effected substantially simultaneously with the detection of the occurrence of engine acceleration.

摘要： The invention relates to an air-fuel (A/F) ratio controller of an internal combustion engine, which is provided with a constant-voltage circuit between the heater for heating the A/F ratio sensor and the power-supply source. Regardless of variation of voltage outputted from the power-supply source, the A/F ratio controller securely maintains the heater voltage constant and prevents occurrence of error in the signal outputted from the A/F ratio sensor by correctly operating the oxygen-concentration detecting element whose measuring precision is solely dependent on temperature.

摘要： An automotive electronic control device includes an electronic control unit 6 for controlling an automotive alternator 2 and the ISCV (Idling Speed Control Valve) 8 of the engine. To improve the mileage of the automobile, the duty factor of the alternator 2 is reduced to zero when the electric load is a light load. Further, when the increase in the load current I.sub.L during the idling is above a load current threshold increment level .DELTA..sub.LT, the ISCV (Idling Speed Control Valve) 8 is controlled to increase the air intake, and, simultaneously, the duty factor of the alternator 2 is reduced to a low level for a predetermined length of time equal to the response time in which the rpm of the engine responds to the increase of the air intake effected by means of the ISCV (Idling Speed Control Valve) 8. The duty factor of the alternator 2 is gradually increased thereafter. The idling rpm of the engine can thus be stably controlled when a heavy electric load is turned on.

摘要： An air-fuel (A/F) controller of an internal combustion engine, which computes an average value of a plurality of duty ratios of the voltage supplied to the heater according to the engine speed and the engine load periodically detected during a period from a predetermined moment up to the present, and fixes said average value as the present duty ratio of the voltage to be supplied to the heater, since the A/F ratio sensor is heated not only by the heater but also by exhaust gas. The A/F ratio controller smoothes the variation of voltage to be supplied to the heater by applying the computed average value as the present duty ratio of the supply voltage which is to be supplied to the heater. Accordingly, even when the driving condition is in high-speed, variation of the temperature borne by the heater is mild and smooth, and thus, the temperature of the oxygen-concentration detecting element does not rise suddenly. Furthermore, the A/F ratio controller corrects the above-mentioned present duty ratio of the voltage to be supplied to the heater according to the supply voltage to be supplied to the heater.
摘要翻译：一种内燃机的空燃料（A / F）控制器，其根据发动机转速和在从一燃料发动机的时间段周期性地检测到的发动机负荷来计算提供给加热器的电压的多个占空比的平均值并且将所述平均值固定为要供给到加热器的电压的当前占空比，因为A / F比传感器不仅由加热器而且被排气加热。 A / F比率控制器通过将计算的平均值作为要供给到加热器的电源电压的当前占空比来平滑要提供给加热器的电压的变化。因此，即使在驱动条件高速的情况下，由加热器承受的温度变化也温和平滑，因此氧浓度检测元件的温度不会突然上升。此外，A / F比率控制器根据供给到加热器的供给电压来校正上述提供给加热器的电压的占空比。
