    摘要： On an outer peripheral portion of a rotor (1), three protrusions are provided per each cylinder. A pickup coil 2 is disposed facing to the outer peripheral portion with a predetermined distance. A rotation signal (S.sub.0) is converted to a rotation signal pulse (S.sub.1) having three pulses (A, B and C) per each cylinder corresponding to the three protrusions. According to the first signal (A) of the rotation signal pulse (S.sub.1) the cranking ignition period (A.sub.1) is determined. According to the second signal (B) of the rotation signal pulse (S.sub.1), the starting timing for flowing current to the ignition coil (8) is decided. According to the third signal (C) of the rotation signal pulse (S.sub.1), the ignition timing at cranking operation is defined by detecting time intervals (3t, t, 2t) between the three signals (A, B, C).

    摘要： A method of controlling the air-fuel ratio so as to be effectively maintained at a desired air-fuel ratio of .lambda.=1 is composed of a combination of an electronic map control for effecting the air-fuel ratio control on the basis of map data read out from a data map stored in ROM as air-fuel ratio control data in correspondence to various operation parameters of an engine and an O.sub.2 -feedback control for controlling the air-fuel ratio on the basis of oxygen quantity detected from the exhaust gas. Upon the occurrence of changes in the control quantity for a predetermined number of times in the course of the O.sub.2 -control, the latter is changed over to the map control. At that time point, a control quantity for the map control is corrected on the basis of a mean control quantity during the O.sub.2 -feedback control. Unless a significant variation takes place in the engine operating conditions, the map control is continued for a predetermined time and then changed over to the O.sub.2 -control. Upon the occurrence of a significant variation in the engine operating conditions, the map feedback control is immediately changed over to the O.sub.2 -control.

    摘要： An apparatus for controlling the operation of an internal combustion engine having a carburetor, especially, the air-fuel ratio and the rate of exhaust gas recirculation, controls the air-fuel ratio of the air-fuel mixture supplied to the engine in the steady operating condition of the engine on the basis of predetermined data determined relative to the engine crankshaft rotation speed and intake vacuum and stored previously in a memory. A three-way catalyst is used to purify engine exhaust gases, and an output signal from an O.sub.2 sensor in the exhaust system is fed back for the control of the air-fuel ratio in the engine exhaust gases. A circuit is provided to check whether this feedback control is normally carried or not. The air-fuel ratio of the air-fuel mixture supplied to the engine in an unsteady operating condition of the engine is controlled by regulating the amounts of fuel and air supplied to the engine while bypassing the carburetor, on the basis of the sensed values of the intake vacuum, engine crankshaft rotation speed and engine temperature and also depending on the throttle valve position. For the control of the rate of exhaust gas recirculation, an upper limit and a lower limit of the rate of opening of a recirculation rate regulating valve are determined on the basis of the sensed throttle valve opening, and other predetermined data determined relative to the engine crankshaft rotation speed and intake vacuum is read out from the memory to limit the rate of opening of the recirculation rate regulating valve.

    摘要： An ignition timing control apparatus for an internal combustion engine having a plurality of cylinders. The apparatus includes a knock sensor for detecting a knocking condition in the engine, sensors for detecting other operating conditions of the engine, a microprocessor unit for receiving signals from the sensors to determine a basic ignition timing of the engine and generate an ignition timing control signal, and a power transistor circuit responsive to the ignition timing control signal from the microprocessor unit to switch on and off the primary current in an ignition coil and generate a high-voltage ignition signal. The microprocessor unit has a control function of retarding the basic ignition timing a predetermined amount in response to a knock detected during an ignition operation at the basic ignition timing and another control function of gradually restoring the retarded ignition timing to the basic ignition timing in response to a knock detected during an ignition operation at the retarded ignition timing from the basic ignition timing. The apparatus includes control means responsive to the occurrence of a knock to correct the basic ignition timing for each cylinder of the engine whereby the basic ignition timing of each cylinder is controlled to be retarded in response to the detection of a knock in each cylinder.
