摘要： A misfiring sensing apparatus for an internal combustion engine measures the length of time required for two periods during the operation of an engine, each of the periods corresponding to a predetermined number of degrees of rotation of the crankshaft of the engine and corresponding to prescribed positions of the pistons of the engine. The two periods are selected so that the ratio of the lengths of the two periods will change when one of the cylinders of the engine is misfiring. Misfiring is detected based on the value of the ratio. In one form of the invention, misfiring is sensed by comparing the ratio with a reference value. In another form of the invention, the ratio is used to calculate a value indicative of the current angular acceleration of the crankshaft of the engine, and the calculated value is compared with a reference value to determine whether knocking is taking place.

摘要： An apparatus for defecting occurrence of misfiring in an internal combustion engine with improved reliability. A change in an angular velocity of a crankshaft of the engine and a change in the output of an air/fuel ratio sensor are monitored. Only when both changes indicate occurrence of misfiring independently from each other, it is decided that misfiring in the cylinder has taken place. Reliability in misfiring detection is improved by using the results obtained through at least two mutually different types of misfiring detections.

摘要： A method and apparatus capable of detecting the occurrence of misfiring in an internal combustion engine with high reliability over a wide engine operation range with a simplified structure. Starting from a fact that an engine acceleration changes in dependence upon combustion states in the engine cylinders, a ratio between two periods before and after a predetermined crank angle reference position is successively determined. An angular acceleration of the crankshaft is then determined on the basis of a difference between a current ratio and a preceding ratio for each cylinder. Subsequently, a change in the crankshaft acceleration is determined for comparison with a predetermined value at every ignition timing for each cylinder. If the change exceeds the predetermined value, it is determined the occurrence of misfiring. The method can be carried out by making use of only an output signal of a crank angle sensor which is usually utilized for ignition timing control of the engine.

摘要： A misfire detecting device of an internal combustion engine comprises a pressure detector(s) for detecting an inner cylinder pressure of the engine, a crank angle detector for detecting a crank angle, and a misfire detector for detecting a misfire based on signals from the pressure detector and the crank angle detector. The misfire detector judges that the engine is under a misfire, when a comparison is made between a first integrated value of an indicated inner cylinder pressure before a predetermined crank angle of a combustion cycle of the engine and a second integrated value of the indicated inner cylinder pressure after the predetermined crank angle, and when there is a difference between the first value and the second value by less than a predetermined value.

摘要： A formation information storage unit stores formation information regulating a formation which characters should form. A character control unit turns off assessment of contact between allies when the characters are to formate and, based on formation information, assembles the respective characters in respective positions. Then, after the characters are assembled, the character control unit turns contact assessment back on. Further, when the characters are to attack, the character control unit moves front row characters toward enemy characters and makes back row characters follow the front row characters, while maintaining a certain amount of space therebetween. Then, when a front row character is destroyed, a back row character replaces the destroyed character.

摘要： A self-diagnosis apparatus diagnoses an exhaust gas recirculating system of an internal combustion engine based on an amount of change in an intake pressure in a intake pipe which is caused by opening of an exhaust gas recirculation control valve which is disposed in a exhaust gas recirculating passage communicating between the intake pipe and an exhaust pipe. The apparatus determines whether or not a difference in engine speeds and/or amounts of engine control as measured before and after the exhaust gas recirculation control valve is opened exceeds a predetermined value, and executes the diagnosis when the difference in the engine speeds is not greater than a predetermined value and/or when the difference in the engine control amounts is not greater than a predetermined value.
