摘要： 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.

摘要： A method for controlling drive of an injector for an internal combustion engine which is capable of reducing a minimum injection quantity available for the control to increase a dynamic range of the injector is disclosed. A voltage across a solenoid coil is stepwise increased when a drive pulse is generated, so that a current fed to the solenoid coil is increased to a level higher than that of the drive current at the time when an injection valve starts port opening operation. Then, the drive current is gradually reduced toward a hold value required to hold the injection valve at a port opening position at a time-based variation ratio less than that of the drive current at the time when the voltage across the solenoid coil is stepwise decreased from a peak value, so that the voltage is stepwise reduced at the time when the drive pulse is extinguished, resulting in the drive current being extinguished.
摘要翻译：公开了一种用于控制内燃机喷射器的驱动方法，该内燃机能够减少可用于控制的最小喷射量以增加喷射器的动态范围。当产生驱动脉冲时，螺线管线圈两端的电压逐步增加，使得馈送到螺线管线圈的电流增加到高于喷射阀开启端口打开操作时驱动电流的电流。然后，将驱动电流逐渐减小到在电磁线圈的电压逐步减小的同时以比驱动电流的时间变化率小的方式将喷射阀保持在开口位置所需的保持值从峰值，使得驱动脉冲熄灭时电压逐步降低，导致驱动电流熄灭。
