    • A control system for an internal combustion engine, which is capable of properly setting fuel injection timing according to the actual degree of delay of the amount of fresh air to be supplied to cylinders of the engine, thereby making it possible to positively suppress torque variation, when the control system has switched an air-fuel ratio mode between a lean mode and a rich mode. The control system controls the air-fuel ratio of a mixture by switching the air-fuel ratio mode. In the lean mode, the control system sets a target fresh air amount for the lean mode, and in the rich mode, it sets a target fresh air amount for the rich mode. Upon switching the air-fuel ratio mode, the control system corrects the fuel injection timing according to the difference between the target fresh air amount for the lean mode or the rich mode and the detected fresh air amount.
    • 一种用于内燃机的控制系统,其能够根据供给到发动机的气缸的新鲜空气量的实际延迟时间来适当地设定燃料喷射正时,从而可以显着地抑制转矩变化, 当控制系统在瘦模式和富模式之间切换空燃比模式时。 控制系统通过切换空燃比模式来控制混合气的空燃比。 在瘦模式下,控制系统为稀薄模式设定目标新鲜空气量,在富模式中,为富模设定目标新鲜空气量。 在切换空燃比模式时,控制系统根据稀薄模式或富模式的目标新鲜空气量与检测到的新鲜空气量之间的差异来校正燃料喷射正时。

    • The present invention provides a fuel control for an internal-combustion engine having an exhaust gas purifying device that is disposed in an exhaust system of the engine. A reducing agent is supplied to the exhaust gas purifying device by injecting fuel in an expansion stroke or an exhaust stroke of the engine. An intake air amount supplied to the engine is controllable. The fuel control includes decreasing the intake air amount supplied to the engine during the fuel injection for the supply of the reducing agent. The fuel control also includes advancing an injection timing of the fuel injection for the supply of the reducing agent when an actual intake air amount is less than a desired intake air amount or when an actual boost pressure is higher than a desired boost pressure. The advancement of the injection timing improves the combustibility of engine while decreasing the HC exhaust amount.
    • 本发明提供一种具有排气净化装置的内燃机的燃料控制装置,该排气净化装置设置在发动机的排气系统中。 通过在发动机的膨胀冲程或排气冲程中喷射燃料,将还原剂供给到排气净化装置。 供给发动机的进气量是可控的。 燃料控制包括减少在用于供给还原剂的燃料喷射期间供给到发动机的进气量。 燃料控制还包括当实际进气量小于期望进气量时或当实际增压压力高于期望的增压压力时,推进用于供给还原剂的燃料喷射的喷射定时。 喷射正时的进行提高了发动机的可燃性,同时降低了HC排气量。
