摘要： A method for controlling air-fuel ratio of the mixture to be supplied to the engine detects whether or not the amount of the fuel to be supplied to the engine is greater than a reference amount. A feedback control in which the air/fuel ratio is corrected according to an oxygen concentration in the exhaust gas is performed when the amount of the fuel to be supplied to the engine is equal to or smaller than the reference level, while an open loop control in which the air/fuel ratio of the mixture is determined irrespective of the oxygen concentration is performed if an operational state of the engine in which the amount of the fuel to be supplied to the engine is greater than the reference level has continued for more than a predetermined time period.

摘要： A method for detecting an abnormality in the functioning of an electronic control system of the type including at least one input means, and at least one output means, wherein the input means is operable to detect the value of a parameter determining the operation of the output means and generate a signal indicative of the detected parameter value, on the basis of which the operation of the output means is controlled. First, a determination is made as to whether or not a predetermined condition exists wherein determination of the above abnormality can be effected. When the predetermined abnormality detection-permitting condition exists, it is determined whether or not the above detected parameter signal value from the input means or an operating amount signal indicative of the operation of the output means has a value satisfying a predetermined condition of normal operation. When the detected parameter signal value is determined not to show a value satisfying the above predetermined condition of normal operation, the time elapsing from the determination of dissatisfaction of the same condition is counted. When satisfaction of the predetermined condition of normal operation is determined before the counted elapsed time value reaches a predetermined value, the counting is interrupted. When the counted elapsing time value reaches the predetermined value, it is diagnosed that an abnormality exists in the functioning of the above corresponding input means or output means. When a predetermined abnormality detection-prohibiting condition exists after the counting of the elapsed time has been started and before the counted elapsed time value reaches the above predetermined value, the counting is also interrupted. The present abnormality detecting method can advantageously be applied to an electronic control system for internal combustion engines.

摘要： A fuel supply control method of controlling the quantity of fuel being supplied to an internal combustion engine after cranking thereof. Upon generation of a predetermined control signal immediately after the cranking of the engine, an initial value of a fuel increment is set, which corresponds to the engine temperature. Subsequently, the set initial value is decreased at a predetermined rate upon each generation of the predetermined control signal. A quantity of fuel is set by the use of the thus decreased value of the fuel increment and supplied to the engine in synchronism with generation of the predetermined control signal. When the fuel increment has a value larger than a predetermined reference value, the value of the fuel increment is decreased at a first rate, while when it has a value smaller than the predetermined reference value, it is decreased at a second rate smaller than the first rate. Preferably, the predetermined reference value assumes a value dependent upon the initial value of the fuel increment, e.g. a product obtained by multiplying the initial value of the fuel increment by a predetermined coefficient. Further preferably, when the fuel increment value is smaller than a fixed value, it is decreased at the second rate, even if it is larger than the predetermined reference value.

摘要： A fuel supply control method for electronically controlling the quantity of fuel being supplied to an internal combustion engine having a turbocharger, in response to values of engine control parameters including at least pressure in the intake passage of the engine, the method having a fail-safe function for an abnormality in the functioning of a pressure detecting means for detecting the above intake passage pressure. When there occurs an abnormality in the above pressure detecting means and at the same time, if the engine is operating in a predetermined supercharged operating condition, control is effected by interrupting the fuel supply to the engine during an interval of time when a condition is satisfied that an abnormality occurs in the absolute pressure detecting means while simultaneously the engine is operating in the above predetermined supercharged operating condition. Preferably, either when a value of the intake passage pressure detected by second pressure detecting means exceeds a predetermined value, or when a throttle valve opening of the engine exceeds a predetermined value, it is determined that the engine is operating in the above predetermined supercharged operating condition.

摘要： A device for correcting the air/fuel ratio of a mixture being supplied to an internal combustion engine, by the use of a correction coefficient which has its value determined as a function of intake air temperature in the intake pipe of the engine. The correction coefficient has a predetermined constant value at intake air temperature higher than a predetermined value, and has its value increasing as the intake air temperature decreases from the above predetermined value. A decrease in the evaporation rate of fuel being supplied to the engine at low intake air temperature is thus compensated for by the above air/fuel ratio correction.

摘要： A fuel supply control method for controlling the fuel supply to an internal combustion engine at deceleration, wherein the fuel supply to the engine is interrupted when the engine is operating in a predetermined operating region while it is decelerating. The fuel supply is interrupted when the engine is operating in either of the following operating conditions: (1) when the throttle valve is in a substantially fully closed position while the engine is decelerating; and (2) when the throttle valve is in a position other than the substantially fully closed position and simultaneously the engine is operating in a predetermined operating region determined by the engine rotational speed and another engine operation parameter relating to the intake air quantity of the engine, preferably, the intake passage pressure. Preferably, the above predetermined operating region of the engine is determined by the intake passage pressure which has different predetermined values between at fuel cut initiation and at fuel cut termination of the engine, and the difference between the above two different predetermined values of the intake passage pressure is set to vary in response to the rotational speed of the engine. Furthermore, the fuel cut operation is continued until the engine decelerates to predetermined rpm which is set in dependence upon the engine temperature.

摘要： An amount of fuel to be supplied to an internal combustion engine is determined in dependence upon operating conditions of the engine and is corrected by a correction variable dependent upon atmospheric pressure. The correction variable is set so as to increase with a decrease in atmospheric pressure, and the set value of the correction variable is modified so as to decrease with a rise in the engine rotational speed. The correction variable resulting from this modification is added to the amount of fuel to be supplied to the engine to correct the same.
