摘要： The basic fuel injection amount determined in accordance with the rpm and the amount of air drawn into an engine is corrected by first, second and third compensation amounts determined in accordance with the engine operating conditions. The second compensation amount is varied by a predetermined value in response to the output of an O.sub.2 sensor at intervals of a predetermined time. The third compensation amount is read out from the location of a non-volatile memory addressed in accordance with the engine rpm and the intake air amount, varied by another predetermined value at intervals of another predetermined time in accordance with the value of the second compensation amount and stored again in the location from which it was read out. Before starting the compensation of the fuel injection amount, the particular bit pattern stored in the non-volatile memory is checked so as to self-check the third compensation amount data in the non-volatile memory.

摘要： The amount of fuel supplied to an internal combustion engine is determined by controlling the opening interval of each fuel injection valve by correcting a standard interval obtained from the amount of intake air and engine speed by first to third correction factors. The first correction factor is dependent on coolant and intake air temperatures, while the second correction factor is dependent on a gas sensor output indicative of the air/fuel ratio of the mixture supplied to the engine. A plurality of third correction factors is provided for different amounts of intake air. Some of the third correction factors corresponding to intake air amounts at which the engine has been operated, are corrected in accordance with the value of the second correction factor. The state of correction is detected and when third correction factor has been corrected in the same direction by a relatively large amount, all of the third correction factors, which have been stored in a memory, are uniformly modified to renew the stored data.

摘要： A method for preventing overheating of an exhaust purifying device by means of an air-flow sensor for sensing the amount of air drawn into an engine to generate an analog voltage corresponding to the amount of air drawn, an intake-air temperature sensor for sensing the temperature of the air drawn into the engine to generate an analog voltage corresponding to the temperature of the air drawn, a water temperature sensor for sensing the temperature of the engine cooling water temperature to generate an analog voltage corresponding to the cooling water temperature, a temperature sensor mounted on a converter, an RPM sensor for sensing the rotational speed of the engine to generating a pulse signal of a frequency corresponding to the engine speed, and a circuit responsive to the detection signals from the sensors for computing the desired amount of fuel injected. The computing circuit controls the ON and OFF periods of fuel injection valves to adjust the fuel injection quantity. When the exhaust temperature exceeds a predetermined value, the air-fuel ratio is compensated for the then current engine operating conditions and the compensation amount is then stored in a memory, whereby each time the same engine operating conditions are repeated, the air-fuel ratio is compensated in accordance with the stored compensation data to thereby prevent overheating of the exhaust purifying device.

摘要： An apparatus for controlling an air-fuel ratio of a combustion engine with a memory device for storing correct values for air-fuel control in accordance with an intake condition of said combustion engine and a rotation speed of the same. In the apparatus, an air-fuel ratio represented by the exhaust gas composition of the internal combustion engine is sensed and the sensed value is integrated. When the integrated value from the integrator fails within a predetermined range of values, one of the correction values for the air-fuel ratio control is corrected in accordance with a current condition of the internal combustion engine. When the integrated value falls outside the predetermined range, the correction values are replaced by a predetermined reference value and an air-fuel ratio of mixture supplied to the combustion engine is controlled in accordance with the correction values for the air-fuel ratio stored.

摘要： A mixture control system comprises an oxygen sensor for generating a sensor signal varying linearly as a function of the oxygen concentration of exhaust emissions from an internal combustion engine when the air-fuel ratio of mixture supplied thereto is leaner than stoichiometric value. Optimum values of the sensor signal are stored in storage locations of a memory addressable as a function of detected engine operating parameters. A data processor determines the quantity of fuel to be supplied to the engine in accordance with the detected engine operating parameters, addresses the memory as a function of the detected engine operating parameters, detects a difference between the sensor signal and a signal addressed in the memory, integrates the difference and corrects the fuel quantity with the integrated value.

摘要： In an air-fuel ratio control system for an internal combustion engine, the basic fuel injection amount computed from engine parameters such as engine speed and intake air flow is corrected by using map having air-fuel ratio compensation data stored battery back-up in accordance with the engine parameters. The compensation data is read out of the map in accordance with the parameters at the time of detection of the stable combustion state of the engine. When an output of an oxygen sensor is on lean side, a predetermined amount is added to the data thus read, while when the output of the oxygen sensor is on rich side, a predetermined amount is subtracted from the data thus read, thereby renewing the stored value.

摘要： A closed loop mixture control system for internal combustion engines is responsive to a signal derived from an exhaust gas sensor. The sensor signal is time-integrated in a direction depending on the level of the gas sensor output to derive a first mixture corrective setting of the control system. Second corrective settings or learning data are established for the control system in correspondence with the amount of air supplied to the engine. Each of the latter settings is varied as a function of time in a direction depending on the value of the time-varying first corrective setting relative to a reference so that the second settings are automatically updated to meet varying engine performance such as aging. One of the second corrective settings is selected in response to the detected quantity of the supplied air and multiplied by the first corrective setting to correct the basic mixture control setting of the system toward an optimum value. All of the second corrective settings are reset to appropriate values, for example, "1" at the instant the engine is started if an average value of the second settings is greater than a predetermined value to compensate for different fuel vaporizations.

摘要： In a closed loop control system for air/fuel ratio control of an internal combustion engine, an integration correction factor is derived from the output signal of a gas sensor indicative of the concentration of an exhaust gas component, and an engine condition correction factor is selected from a memory in which a plurality of engine condition correction factors are prestored in the form of a table. The engine condition correction factor is renewed in accordance with the variation in the value of the integration correction factor so as to perform learning control. In order to prevent each of the engine condition correction factors from assuming an undesirable value which are far deviated from its standard, a constant or variable limit value is set. The limit value may be set by calculating some typical engine condition correction factors. The correction factors will be used to modify a basic quantity of fuel to be injected into each cylinder of the engine for feedback controlling the air/fuel ratio of the air/fuel mixture.
