摘要： Spark ignition timing of an internal combustion engine is oscillated on each side of a variable reference setting during successive ignition phases and the resultant engine speed is detected during at least three successive phases. The detected engine speed values are compared one against each other to determine whether they satisfy one of two specified conditions. The variable reference is adjusted in a direction toward an optimum position depending on which one of the conditions is satisfied. At least one of controlled parameters including the magnitude of the oscillated setting with respect to the variable reference, the length of the ignition phase and the amount of the adjusted reference setting, is varied as a function of an engine operating parameter.

摘要： An engine control method generally applicable to those control systems of the engine such as an ignition system, fuel injection system, etc., which are controlled to optimum operation in accordance with engine operating conditions. Angular pulses are generated each time the output shaft of the engine rotates a predetermined angular amount. These angular pulses are counted from the occurrence of a position pulse which is generated at a predetermined angular position of the output shaft of the engine. A central processor is employed to calculate a first angular position at which an electric device for the engine is to be controlled. The central processor also calculates a time interval between the first angular position and a second angular position at which one of the angular pulses is to be provided just before the first angular position. When the angular pulse counting reaches a value corresponding to the second angular position, fixed frequency clock pulses are then counted. When the calculated required time interval has passed as determined by counting the fixed frequency clock pulses, the electric device is controlled.

In this method, an operation starting timing and an operation ending timing of the control system, e.g., in the case of the ignition system, an ignition coil energization starting timing and an ignition timing (an energization ending timing) are computed at each of predetermined computing cycles, and the latest computed ignition timing, for example, which is computed after the coil energization has been started further taking into consideration of the actual coil energization timing and a minimum required energization period is compared with an ignition timing computed in the preceding computing cycle, and a corrective computation of the latest computed ignition timing is carried out depending on the result of the comparison to obtain an optimum ignition timing. Also the history of the ON-OFF state of a bleed valve in an engine air supply system is monitored. The actual duty cycle of the valve is compared with a desired duty cycle to determine whether or not to open the valve for a succeeding time period.

摘要： An engine control method and apparatus generally applicable to those control systems of the engine such as an ignition system, fuel injection system, etc., which are controlled to optimum operation in accordance with the engine operating conditions. A plurality of angular pulses are generated during each rotation of the engine and these pulses are counted. In response to each pulse, an angular interrupt request is generated and the interrupt is performed in response thereto. The angular interrupt routines are of the highest priority and are executed irrespective of the execution status of the central processing unit to control an electric device associated with the engine in accordance with control data calculated by the central processing unit. Program interrupt requests are generated during selected angular interrupt routines when the counted number of angular pulses reaches a predetermined value. Program interrupt routines of lower priority than the angular interrupt routines are then executed to calculate the control data for the electric device.

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： 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.

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.
