摘要： In an optimum control for an internal combustion engine, a engine is operated by dithering the value of a selected one of engine operating control variables from a value of the selected control variable which is obtained by calculation in accordance with detected values of operating parameters of the engine, and a direction of improving either one of a fuel consumption rate and an output of the engine is decided on the basis of a detected change of an engine operating condition, thereby correcting the value of the selected control variable. In the optimum control, the time period for detecting a change of an engine speed within the time period for effecting the dithering is increased or decreased as the engine speed increases or decreases, respectively. Thus, this optimum control makes it possible to perform accurate control with a reduced dither quantity and a shorter dither period than previously.

摘要： Spark ignition timing of an internal combustion engine is oscillated on opposite sides of the setting of a variable reference timing and the resultant engine speed is detected in at least three successive phases of the oscillation and stored in respective memories. The contents of the memories are compared with each other to detect whether they establish one of two predetermined relationships which occur exclusively in the absence of a manual command input to the engine. The variable reference setting is adjusted by a predetermined amount in a specified direction in response to the established relationship. The process is repeated so that the reference setting approaches an optimum advance angle at which the engine output torque is at a maximum. When the reference setting is at or near the optimum point or when a manual command engine input is present, the registered engine speed values establish a relationship other than the predetermined ones and the reference setting is not adjusted.

摘要： In an apparatus for controlling an engine, as an air flow sensor for measuring intake air flow quantity, a heater resistor having temperature-resistance characteristic and a temperature sensitive resistor for sensing air temperature are provided in an intake passage, and heating electric power is supplied to the heater resistor in response to a start signal generated periodically. The heating electric power is cut off when the temperature of the heater resistor is raised to a specified reference temperature predetermined in accordance with the air temperature, so that an output signal indicative of the time width in which the heating electric power is supplied is applied to an electronic control unit to measure air flow quantity therefrom. Further, compensation coefficient stored in a memory is derived in correspondence to the intake air temperature sensed by the temperature sensitive resistor, and the output signal is compensated for by the compensation coefficient to compensate the measured air flow quantity. Based on the compensated air flow quantity, fuel injection quantity, ignition timing or the like is computed in the electronic control unit.

摘要： A heater, which comprises an element whose resistance varies with changes in temperature, and a temperature element are provided in the air intake pipe of an engine. This heater and temperature element together with resistors form a bridge circuit to which heating power is supplied via a transistor. An engine control unit generates start signals Tin simultaneously with the rotation of the engine. A flip-flop circuit is set by these start signals and, when set, the transistor is turned on and the heating power rises. The output signal from the bridge circuit is supplied to a comparator and the output signal of the comparator resets the flip-flop circuit, which outputs a pulse-shaped signal representing the airflow quantity as a length of time. This pulse-shaped time signal is sent via a constant current circuit to another comparator, where it is compared with a reference voltage and the output signal from the comparator is supplied together with the above time signal to an exclusive OR circuit. This exclusive OR circuit outputs a first and second pulse signal as the measurement output signal Tout synchronously with the rise and fall of the time signal and this signal is supplied to the engine control unit.

摘要： An air flowrate measuring apparatus with a heat wire measures the flow rate of the air flowing through the intake pipe of an engine. The apparatus has a temperature sensitive element which has a specific temperature-resistance characteristic and is disposed in the intake pipe. Constant heating voltage is applied to this element in response to a start signal, thus heating the element. When the temperature of the element rises to a specified value, the application of the voltage is stopped. At the same time, a pulse signal whose width corresponds to the period of applying the voltage is generated. The signal is supplied to an interface circuit through a drive circuit driven by a reference voltage which has been also used to control the heating voltage. The interface circuit comprises two wave-shaping circuits. The first wave-shaping circuit has a filter means of a small integration time constant. The second wave-shaping circuit has a filter means whose integration time constant is large enough to remove noise from the input signal.
