    • An electronic control unit for a two-cycle internal combustion engine including an exhaust control valve which adjusts exhaust timing, a valve controller which controls the exhaust control valve, and a reversal controller which controls reversing a rotational direction of the engine in accordance with an instruction for reversal. In order to raise the probability of a success in reversing the rotational direction of the engine by generating a stable combustion pressure during the reversal of the rotational direction, there is provided valve opening and closing operation inhibition means which inhibits an opening and closing operation of the exhaust control valve by fixing the exhaust control valve in a fully-closed position while the reversal controller is performing control to reverse the rotational direction of the engine.
    • 一种用于双循环内燃机的电子控制单元,其包括调节排气正时的排气控制阀,控制排气控制阀的阀控制器和根据指令控制发动机的旋转方向的反转控制器 为了逆转。 为了提高通过在转动方向的反转期间产生稳定的燃烧压力而使发动机的旋转方向成反比的可能性,设置有开闭动作禁止装置, 排气控制阀通过将排气控制阀固定在完全关闭位置,同时反向控制器执行控制以使发动机的旋转方向反转。

    • A method for driving an injector for feeding an internal combustion engine with fuel which is capable of improving starting characteristics of the engine. A power circuit is provided which functions to charge a power capacitor utilizing an output of a generating coil, so that feeding of an injection command signal permits a driving current to flow through a driving coil of an injector. A period of time required to permit charges in an amount necessary to drive the injector to be accumulated in the power capacitor is defined to be an injector drive prohibition period, during which generation of the injection command signal is prohibited, to thereby prohibit flowing of the driving current. The injector drive prohibition period is elapsed, so that a required amount of charges are accumulated in the power capacitor, followed by generation of the injection command signal, to thereby permit the driving current to flow the driving coil.
    • 一种用于驱动能够提高发动机起动特性的燃料的内燃机的喷射器的方法。 提供了一种功率电路,其功能是利用产生线圈的输出对功率电容器充电,从而使得注入命令信号的馈送允许驱动电流流过注射器的驱动线圈。 允许将驱动注入器积蓄在电力电容器中所需的量的电荷所需的时间定义为禁止注入命令信号的产生的喷射器驱动禁止期间,从而禁止 驱动电流。 喷射器驱动禁止期间经过,使得所需量的电荷累积在电力电容器中,随后产生喷射命令信号,从而允许驱动电流流过驱动线圈。
