摘要： A stop control system for an internal combustion engine, which controls a stop position of a piston of the engine, is provided. An valve opening amount of an intake air flow rate control valve is determined based on the detected engine rotational speed and the detected crank angle after the ignition switch is turned off, and the intake air flow rate control valve is controlled so that the valve opening amount of the intake air flow rate control valve coincides with the determined valve opening amount. For example, the valve opening amount of the intake air flow rate control valve is determined according to the crank angle at the time the engine rotational speed decreases to reach a predetermined range, and the intake air flow rate control valve is controlled to be opened. With this control, the intake air amount of the engine is increased so that the stop position of the piston coincides with the desired position.

摘要： Disclosed is an internal-combustion engine controller capable of improving emission characteristics at a start of an internal-combustion engine. When injection during an exhaust stroke is controlled in a port-injection engine, the engine controller ECU performs the first fuel injection during t1 to t2 according to a memory-based crank angle as illustrated in FIG. 12(b) at a fuel injection timing before determination of an actual stroke. Thus, the injected fuel has been introduced into a cylinder during the actual stroke. If fuel is not injected during t1N to t3N within the next exhaust stroke as denoted by the solid line, this causes misfire in the cylinder, so that the engine rotation at the start cannot be smooth. Thus, the ECU clears a finished fuel injection flag (F_INJ) at an incorrect crank angle storage determination timing (tJUD) as denoted by the dashed-dotted line, thereby capable of controlling the fuel injection.
摘要翻译：公开了能够改善内燃机起动时的排放特性的内燃机控制装置。在排气冲程中的喷射在端口喷射发动机中被控制的情况下，发动机控制器ECU根据如图3所示的基于存储器的曲柄角在t1至t2期间执行第一燃料喷射。在确定实际行程之前的燃料喷射正时12（b）。因此，在实际行程中，喷射的燃料已被引入气缸。如果在实线所示的下一个排气冲程期间在t1N至t3N期间没有喷射燃料，则这导致气缸中的失火，使得起动时的发动机转速不能平稳。因此，如虚线所示，ECU以不正确的曲柄角存储确定定时（tJUD）清除完成的燃料喷射标志（F_INJ），由此能够控制燃料喷射。

摘要： A fuel supply apparatus for an internal combustion engine having a plurality of cylinders, which supplies fuel through fuel injection valves provided corresponding to the plurality of cylinders. An amount of fuel supplied to the engine is controlled by changing a fuel injection period of said fuel injection valve, and performing a fuel injection with a plurality of injection modes including a reference injection mode. A fuel injection amount parameter for controlling a valve opening period of the fuel injection valve in the reference injection mode, is calculated according to an operating condition of said engine. When the injection mode is determined to be another injection mode which differs from the reference injection mode, the fuel injection amount parameter is corrected so as to compensate shortage or oversupply of the fuel injection amount according to a correction parameter indicative of a time period which affects a pressure change of the fuel supplied to the fuel injection valve caused by employing the other injection mode.
