摘要： In an internal combustion engine equipped with a pair of intake ports for each cylinder and capable of controlling a quantity of air entering the engine by controlling an intake valve open timing and an intake valve closure timing of each of a pair of intake valves located in the respective intake ports, a two-intake-valve operating mode is used in a high-load, high-speed operating range, whereas a one-intake-valve operating mode is used in predetermined low- and mid-load, low- and mid-speed operating ranges to create a great gas flow within the cylinder. A fuel injector is located in a first one of the intake ports to allow air flow through the first intake port over all operating ranges. An electronic engine control unit switches a compensating mode for an injection amount of fuel injected by the injector, based on changes in a quantity of wall fuel mass flow adhered onto the inner wall surface of the intake port during transient operating conditions, from one of a first compensating mode which is preprogrammed to be suitable for the one-intake-valve operating mode and a second compensating mode which is preprogrammed to be suitable for the two-intake-valve operating mode to the other.

摘要： A control system for a variable displacement internal combustion engine determines effective flow cross sectional area as a predetermined function of a cross sectional area given against a throttle position. The effective flow cross sectional area is used to determine a volumetric airflow ratio. A control unit is connected with cylinder operator means for deactivating and reactivating at least some of engine cylinders and varying strokes in a cycle. The control unit modifies the predetermined function in response to the number of cylinders being activated and the number of strokes in a current cycle.

摘要： To achieve an intermediate lock state in a short period when an engine is stopped and improve the accuracy of confirmation of the intermediate lock state, an engine valve timing control apparatus includes a variable valve timing mechanism configured to vary engine valve timing, and an intermediate lock mechanism configured to restrict relative rotation positions of a first and a second rotor of the valve timing mechanism at an intermediate lock position for starting the engine. Upon detection of an engine stop request, the valve timing mechanism and the intermediate lock mechanism are driven and controlled for establishing an intermediate lock state. When a predetermined period from detection of the engine stop request has expired without detecting the intermediate lock state within the predetermined period, an engine stopping process is executed. Even after the engine stopping process has been executed, monitoring of the intermediate lock state is continued.
