    摘要: An internal combustion engine includes first and second fuel injection valves, a valve actuating device and an ECU. The ECU sets a distribution ratio of the first fuel injection valve to 100% when an accumulation amount Spfi is larger than a predetermined value Xpfi in a predetermined case. The predetermined case is a case where the valve actuating device closes the exhaust valve on an advance side with respect to an exhaust top dead center and a state where a minus overlap is formed between the intake valve and the exhaust valve is established and a case where the distribution ratio of the second fuel injection valve is set to 100%.

    摘要: Provided is a control apparatus for an internal combustion engine which can successfully determine whether or not a failure concerning a stopping operation of an exhaust valve has occurred, without the need of providing a dedicated sensor for the failure determination. An intake variable valve operating apparatus (62) and an exhaust variable valve operating apparatus (64) are included that have valve stop mechanisms capable of switching each operational state of an intake valve (58) and an exhaust valve (60) between a valve operating state and a valve closed/stopped state. It is determined whether or not a failure concerning a stopping operation of the exhaust valve (60) from the valve operating state to the valve closed/stopped state has occurred, on the basis of the magnitude of the negative torque of when an execution request that is accompanied by a valve stop request to switch each operational state of the intake valve (58) and the exhaust valve (60) from the valve operating state to the valve closed/stopped state has been issued, in a case in which it is determined that a failure concerning the stopping operation of the intake valve (58) has not occurred.

    摘要: An engine control system for a vehicle includes a pressure determination module, an adjustment determination module, a target determination module, and a pump control module. The pressure determination module determines a first pressure for a hydraulic fluid provided to fully flexible intake and exhaust valve actuators of an engine. The adjustment determination module determines a pressure adjustment for the first pressure based on a pressure within a cylinder. The target determination module determines a target pressure for the hydraulic fluid based on the first pressure and the pressure adjustment. Based on the target pressure, the pump control module controls a hydraulic fluid pump for an opening timing of an exhaust valve of the cylinder.

    摘要: An object is to provide a control device and control method for a compressed self-ignition type internal combustion engine, which can reduce torque variation due to misfire when the air-fuel ratio varies during compressed self-ignition type combustion, and thereby effectively use the potential for reducing fuel consumption. As the combustion mode, a spark-ignition type combustion mode by use of an ignition plug and a compressed self-ignition type combustion mode which utilizes a pressure increase in a combustion chamber in association with upward movement of piston are selectively set depending on an operational state of the engine, and when the air-fuel ratio in the compressed self-ignition type combustion mode is rich, a regional upper limit of the compressed self-ignition type combustion region is changed toward the lower engine torque side, and when the air-fuel ratio is lean, the regional upper limit is changed toward the higher engine torque side.

    摘要: In one example, a method is described for an engine with a hydraulically actuated phaser for adjusting cam timing. The phaser is controlled by a hydraulic spool valve, for example, having a de-energized position that results in hydraulic force urging the phaser to a base timing. When it is desired to operate the cam timing at base timing, rather then leave the spool valve in a de-energized position that can generate leakage, the spool valve is adjusted to near a null position to reduce the hydraulic pressure drop across the cam journal and thus reduce oil leakage. In this way, it is possible to maintain base timing, while also reducing leakage.
