摘要： A high probability of detecting an erroneous misfire occurs when combustion becomes unstable during jolt control. Therefore, during jolt control the reliability of the misfire detection system is degraded. As a result, the misfire detection system is inactivated during jolt control by discontinuing the misfire detection, or by deliberately deeming no misfire has occurred if jolt control has occurred. Alternatively, the misfire detection sensitivity is masked during jolt control.
摘要翻译：当在颠簸控制期间燃烧变得不稳定时，发生错误的失火的高概率。因此，在颠簸控制期间，失火检测系统的可靠性降低。因此，通过停止失火检测，或者通过故意认为如果发生抖动控制，则不发生失火，在失速控制中失火检测系统被停用。或者，在颠簸控制期间，失火检测灵敏度被屏蔽。

摘要： A misfire-detecting system detects a misfire occurring in an internal combustion engine. A value of sparking voltage for discharging a spark plug of the engine is detected. The detected value of the sparking voltage is compared with a first predetermined value. A degree to which the detected value of the sparking voltage exceeds the first predetermined value is measured. The measured degree is compared with a second predetermined value. It is determined based upon results of the latter comparison whether or not a misfire occurred in the engine. According to a first aspect of the invention, the second predetermined reference value is set based upon detected values of operating parameters of the engine. According to a second aspect of the invention, the determination of occurrence of a misfire is inhibited when the engine is in a predetermined operating condition.

摘要： An ignition coil unit for an internal combustion engine for containing an ignition voltage detective capacitor for misfire discrimination, including a core, a primary and a secondary coil wound around the core, and a case housing the core and the primary and secondary coils which is filled with an insulative material. In this unit, a first conductive electrode plate is placed in the case and electrically connected with the output of the secondary coil, and a second conductive electrode plate is also placed in the case in parallel with the first conductive electrode plate while maintaining a predetermined distance therefrom. An insulator is interposed between the first and second conductive electrode plates forming a capacitor that uses the insulator as the dielectric. When the first plate is fixed to the coil's bobbin at a position close to the secondary coil's higher voltage end such that it cantilevers therefrom, a partition or the like is interposed between the plates so as to prevent the first plate from interfering with the second plate.

摘要： A fuel supply control system which controls an amount of fuel supplied to an internal combustion engine. An ECU detects a value related to an amount of combustion ions generated within cylinders. The detected value is compared with a predetermined value, and the amount of fuel supplied to the engine is corrected based upon the comparison result, when the engine is in a transient operating condition, such as acceleration and deceleration, whereby the responsiveness of the air-fuel ratio feedback control is enhanced to improve drivability and exhaust emission characteristics.

摘要： A device according to an aspect of the invention detects abnormality of spark plugs of an internal combustion engine. A value related to electric resistance across a gap between electrodes of each spark plug is measured. Next, it is determined whether or not the measured value, related to the electric resistance, assumes a value indicating that the electric resistance is below a predetermined value, when the engine is determined to be in a non-combustive state. The spark plug is determined to be abnormal when it is determined that the measured value, related to the electric resistance, assumes the value indicating that the electric resistance is below the predetermined value. A misfire-detecting system according to another aspect of the invention incorporates the above device.

摘要： A method of detecting abnormality in a fuel supply system of an internal combustion engine. An amount of fuel supplied to the engine is controlled in a feedback manner based on an air-fuel ratio correction coefficient set in response to an output signal from at least one exhaust gas component concentration sensor. The method comprises the steps of (1) calculating an abnormality determination value based on the air-fuel ratio correction coefficient, (2) calculating a learned average value of the air-fuel ratio correction coefficient, (3) renewing the abnormality determination value when the calculated learned average value of the air-fuel ratio correction coefficient falls outside a first predetermined range defined based upon the abnormality determination coefficient, and (4) determining that the fuel supply system is abnormal when the renewed value of the abnormality determination value falls outside a second predetermined range defined by predetermined upper and lower limit values.

The two-cycle action cam 1 effects opening of the inlet and exhaust valves once per revolution of the crankshaft and the four-cycle action cam 3 effects opening of the inlet and exhaust valves once per two revolutions of the crankshaft. The four-cycle action is selected when the engine is in the low revolving speed and running at a low load and the two-cycle action is otherwise selected.

摘要： A cooling control system for an internal combustion engine equipped with a supercharger. The control system includes an electrically-driven pump for circulating coolant for cooling the supercharger, and an electrically-driven fan arranged in an engine room. The cooling control system controls the operation of the electrically-driven pump and the operation of the electrically-driven fan, based on an output from a sensor for detecting stoppage of the engine as well as on operation of a timer for counting a predetermined time period. The cooling control system controls, during operation of the engine, the operation of the electrically-driven pump and the operation of the electrically-driven fan, based on an output from a sensor or sensors for detecting operating conditions of the engine.
