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 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： A fuel injection control system for an internal combustion engine comprises an ECU which calculates a direct supply ratio and a carry-off ratio, and detects a predetermined operating condition of the engine in which an increased amount of fuel is to be supplied to the engine. When the predetermined operating condition is detected, a plurality of fuel injection amounts to be sequentially injected by at least one fuel injection valve are calculated based on operating conditions of the engine, the direct supply ratio and the carry-off ratio. Then, an amount of fuel adhering to the intake system of the engine is calculated based on the total sum of the calculated plurality of fuel injection amounts, as well as on the calculated direct supply ratio and the calculated carry-off ratio. At least one of the calculated plurality of fuel injection amounts is corrected based on the calculated amount of fuel adhering to the intake system. Then, at least one fuel injection valve is controlled to sequentially carry out a plurality of fuel injections in one operating cycle of the engine, based on the calculated plurality of fuel injection amounts including the at least one thereof corrected.

摘要： An air-fuel ratio control system for an internal combustion engine calculates an amount of fuel to be supplied to the engine in response to the rotational speed of the engine and a parameter indicative of load on the engine, and an amount of fuel injected into an intake passage and adhering to the inner surface of the intake passage, based upon a direct supply ratio and a carry-off ratio. A feedback correction value is set to such a value that an air-fuel ratio in exhaust gases from the engine becomes equal to a desired value, and the amount of fuel calculated as above is corrected by the direct supply ratio, the carry-off ratio, and the feedback correction value set as above. A control speed at which the feedback correction value is corrected is set based upon at least one of the direct supply ratio and the carry-off ratio.
