    摘要： A control system for an internal combustion engine having a plurality of cylinders each having at least one intake valve, at least one exhaust valve, and a crankshaft. The control system has an electromagnetic driving section which electromagnetically causes opening and closing of at least one of the at least one intake valve and the at least one exhaust valve. A crank angle sensor generates a crank angle signal whenever the crankshaft rotates through a predetermined angle, and a cylinder position sensor generates a cylinder-discriminating signal indicative of a predetermined crank angle of a particular cylinder of a plurality of the cylinders. A piston position sensor detects an operating state or position of the piston of each of the plurality of the cylinders, based on the generated crank angle signal and the generated cylinder-discriminating signal. A CPU starts opening of the at least one of the at least one intake valve and the at least one exhaust valve, based on the detected operating state of the piston.

    摘要： An electromagnetically driven valve control system for an internal combustion engine having at least one intake valve and at least one exhaust valve, and a starter for starting cranking of the engine. A CPU controls an energization time/timing control circuit section to electromagnetically drive at least one of the at least one intake valve and the at least one exhaust valve. The CPU detects a starting signal indicative of starting of the cranking of the engine, and a timer measures a time period elapsed after the starting signal is detected. An inhibiting time period is set, over which the operation of the starter means is inhibited, and the at least one of the at least one intake valve and the at least one exhaust valve is driven in a valve closing direction when the starting signal is detected. The operation of the starter is permitted when the time period elapsed after the starting signal is detected exceeds the inhibiting time period.

    摘要： A fuel injection control apparatus and method for an internal combustion engine are provided for appropriately calculating fuel injection times for an in-cylinder fuel injection valve and a port fuel injection valve, thereby accurately controlling the amounts of fuel supplied to the internal combustion engine from the in-cylinder fuel injection valve and the port fuel injection valve, respectively. The fuel injection control apparatus calculates an in-cylinder fuel injection amount which should be injected by the in-cylinder fuel injection valve, and calculates an in-cylinder fuel injection time which is a valve opening time of the in-cylinder fuel injection valve in accordance with the calculated in-cylinder fuel injection amount and an acquired cylinder internal pressure. The fuel injection control apparatus further calculates a port fuel injection amount which should be injected by the port fuel injection valve, and calculates a port fuel injection time which is a valve opening time of the port fuel injection valve in accordance with the calculated port fuel injection amount and a detected pressure within an intake system.

    摘要： A control system for an internal combustion engine, which can determine just enough amounts of demanded combustion fuel and auxiliary fuel during execution of auxiliary fuel supply, for improvement of fuel economy and drivability and the emission-reducing capability of a catalyst. The control system carries out auxiliary fuel supply for a cylinder during a predetermined time period within the expansion and exhaust strokes, to control the catalyst to a predetermined state for its emission-reducing capability. The control system calculates a whole demanded fuel amount to make oxygen concentration in exhaust gases equal to a predetermined value for controlling the catalyst to the state during auxiliary fuel supply, determines the amount of demanded combustion fuel to be supplied to obtain engine output, and determines the auxiliary fuel amount based on the difference between the whole demanded fuel amount and the demanded combustion fuel amount.
