摘要： When a failure diagnostic device for diagnosing failure of an evaporative emission control system judges that an engine (1) is being run in a running state that satisfies failure diagnosis requiring conditions, it drives a purge control valve (46) so as to open it after detecting an opening position of an idle speed control (ISC) valve (8). If a relatively large load is being applied to said engine at that moment, a threshold value for determining the operation sensitivity of said ISC valve is corrected to be reduced. When a predetermined period of time elapses after a valve opening position of said ISC valve was detected, an opening position of said ISC valve is again detected. When a deviation between the two opening positions is below said threshold value, it is judged that the introduction of purged air by driving said purge control valve is not performed, in other words, that said purge control valve is out of order. When the engine load is increased, since the operation sensitivity of said ISC valve is increased, an erroneous diagnosis is prevented.

摘要： A method of detecting misfire by utilizing the variation of rotation of a crankshaft, capable of detecting the occurrence of misfire accurately with the influence of a detection error eliminated which is ascribed to a structural error of a crank angle sensor used in the detection of variation of rotation of the crankshaft. When a processor receives pulses sequentially from a crank angle sensor, it detects (S2) the length of a period of time between the entry of the detection operation into a region of angle of rotation of crankshaft concerning a cylinder corresponding to the two pulses and the departure of the same operation from the same region. An angular acceleration D omega n of the crankshaft is calculated (S3, S4) by using a correction factor which is determined on the basis of this detected length of period of time and the length of period of time which is free from an error of operation of the sensor and determined by dividing the time required for one turn of the crankshaft by the number of the cylinders. When a calculated value D omega n is smaller than a judgement value, the occurrence of misfire is detected (S5-S7).

摘要： A misfire detecting method capable of detecting the occurrence of misfire accurately without involving a misfire detection error ascribable to the vibratory increase and decrease, which occurs after misfire has happened, of the variation rate of rotation of a crankshaft, and, moreover, requiring no special hardware for this purpose. The angular accelerations D omega n-2, D omega n-1, D omega n and D omega n+1 in the crank angle regions corresponding to the preceding cylinder, two cylinders to be subjected to the detection of misfire and the succeding cylinder are calculated sequentially by a processor to which pulse outputs are inputted from a crank angle sensor. When the values D omega n-1 and D omega n decrease considerably as compared with values D omega n-2 and D omega n-1, a tentative judgement that misfire occurs in the two object cylinders to be detected is made. When the value D omega n+1 then increases appreciably as compared with the value D omega n, the restoration to normal combustion condition is ascertained, and the occurrence of misfire in these two object cylinders to be detected is definitely determined.
