摘要： A control system for an internal combustion engine is provided for a running equipment, which prevents from running in the direction opposed to the driver's intention when reversing the engine is failed although a driver executes a reverse process of reversing the rotative direction of the engine. The rotative direction of the internal combustion engine is detected so as to generate a rotative direction detection signal, and a reverse failure signal is generated when the rotative direction of the engine detected by these detection signals does not correspond to the rotative direction of the engine commanded by a reverse command. When the reverse failure signal is generated, fuel supply to the engine is stopped, and the engine is extinguished so as to stop the rotation.

摘要： A rotational direction change-over control method capable of reversing a rotational direction of an internal combustion engine without discharging unburnt gas. When a reverse command is generated, feed of fuel to the engine is interrupted to reduce a rotational speed of the engine to a set level. An ignition position of the engine is advanced to an excessively advanced position during a reduction in rotational speed to the set level. When the rotational speed is reduced to the set level, feed of fuel is restarted to reverse a rotational speed of the engine. When judgment that the rotational speed is successfully reversed is made, the ignition position is transferred to a position near a top dead center, to thereby maintain rotation of the engine in a direction reversed.

摘要： 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.
