Abstract: Misfire detection system for an internal combustion engine. If misfire is found to occur due to vapor lock temporarily happening, it will erroneously be judged that the structure of the engine or the fuel supply system is out of order. However, vapor lock is an interruption of the flow of fuel in a gasoline engine caused by formation of vapor or gas bubbles, and does not mean the engine or the fuel supply system is degraded in its structure. On the contrary, if misfire is detected in such situation, the misfire detection degrades the reliability of the system. The misfire detection is therefore inactivated during conditions in which vapor lock is liable to occur, by discontinuing the detection, or by deliberately deeming no misfire to occurs even if it is so detected. Alternatively, the reference level for misfire detection is raised during such conditions.

Abstract translation: 内燃机失火检测系统。 如果由于蒸气锁暂时发生发生失火，将错误地判断发动机或燃料供应系统的结构是否有故障。 然而，蒸气锁是汽油发动机由蒸气或气泡形成引起的燃料流的中断，并不意味着发动机或燃料供应系统的结构降低。 相反，如果在这种情况下检测到失火，则失火检测会降低系统的可靠性。 因此，在容易发生蒸汽锁的情况下，通过中止检测，或者故意认为即使检测到不发生失火也会使失火检测失效。 或者，在这种情况下提高了失火检测的参考水平。

Abstract: An ignition system for an internal combustion engine that has at least two spark plugs for each of the cylinders. The number of spark plugs ignited is controlled in accordance with the operational condition of the engine. The system includes an ignition control means for controlling the ignition in such a manner that an all-point ignition in which all the spark plugs are ignited is carried out in a condition where the temperature of the engine is equal to or lower than a predetermined value, and so that a decreased number-point ignition in which the ignition of at least one of the spark plugs is discontinued is carried out in a condition where the temperature of the engine is higher than the predetermined value. By selecting the two-point ignition in a low temperature region in which the temperature of the cooling water is low, reductions in fuel firing performance and combustion speed are prevented, and by selecting the one-point ignition in a high temperature region in which the temperature of the cooling water is high, an increase in the amount of NOx due to excessively high combustion speed is prevented. The ignition may also be controlled on the basis of engine load and exhaust gas recirculation valves.

Abstract: A unipolar ignition of the invention provides a current waveform at the ignitor plug which initially rises relatively slowly, followed by a transition to a fast rising current which quickly peaks and thereafter slowly dissipates. Such a current waveform provides an initially hotter and longer lasting spark which does not harm the ignitor plug of the system or shorten its life expectancy. Neither does the spark create stress on the solid state circuitry which delivers the energy to the ignitor plug. To provide the foregoing spark and current characteristics, an inductor having a saturable core is in series with the ignitor plug, and it provides an initially high inductance which limits the rate of current rise at the plug as energy is transferred from an energy storage device to the plug. As the current through the inductor increases, its core begins to saturate and the effective inductance begins to decrease, allowing the current to rise more quickly. As energy is transferred to the ignitor plug. The increasing saturation, decreasing inductance and increasing current complement one another, causing the rate of current rise to increase quickly to a high value desirable for ignition. Related features of the invention provide for easy diagnostics of the spark and for timing an ignition sequence and providing a repetition rate which aids in a successful ignition.

Abstract: A misfire-detecting system for an internal combustion engine detects a value of sparking voltage generated by the igniting device of the engine after generation of an ignition command signal, compares the value of the detected sparking voltage with a predetermined value, and determines whether or not a misfire has occurred in the engine, based upon the result of the comparison. The misfire-detecting system can discriminate between a misfire attributable to the fuel supply system of the engine and one attributable to the ignition system of the engine, from a detected peak value of the sparking voltage.
