摘要： A fuel injection control method for successively injecting fuel into a plurality of cylinders of an internal combustion engine in predetermined sequence in synchronism with pulses from top-dead-center detecting means which are successively generated immediately after generation of each pulse from cylinder-discriminating means. The method is adapted to perform a fail safe function in the event of occurrence of an abnormality in the cylinder-discriminating means. The number of pulses is counted which are successively generated from the top-dead-center detecting means immediately after generation of each pulse from the cylinder-discriminating means. If no further pulse from the cylinder-discriminating means is detected until the count of pulses from the top-dead-center detecting means reaches a number equal to the sum of the number of the engine cylinders and while the rotational speed of the engine is higher than a predetermined value, the cylinder-discriminating means is regarded as abnormal. Then, injection of fuel into the cylinders is effected in the above predetermined sequence in synchronism with pulses from the top-dead-center detecting means alone, irrespective of generation of subsequent pulses from the cylinder-discriminating means.

摘要： A fuel supply control method for electronically controlling the quantity of fuel being supplied to an internal combustion engine at the start of the engine, in response to values of engine control parameters including at least the engine temperature. When there is an abnormality in an engine temperature detecting means that detects the value of the engine temperature, while the engine is operating in a predetermined starting operating condition, control is effected by gradually increasing the quantity of fuel being supplied to the engine with the progress of time starting from a time the engine starter is switched on, by the use of a predetermined dummy signal indicative of engine temperature, in place of an output signal from the aforementioned engine temperature detecting means. Preferably, the value of the above dummy signal is set so as to change from a higher engine temperature value to lower engine temperature values in a successive and stepwise manner at an interval of a predetermined period of time. Also, the value of the above dummy signal is maintained at a predetermined value in the post-starting operating condition of the engine.

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 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.
