摘要： A controlling apparatus for an engine includes a purge path connected to a sealing-type fuel tank and an intake system of an engine and is configured to allow purge gas containing evaporated fuel from the fuel tank to flow therethrough. A purge valve placed in the purge path is configured to adjust a flow rate of the purge gas. A calculation unit calculates a degree of opening of the purge valve based on a target introduction ratio of the purge gas, and a controlling unit controls the purge valve so as to establish the degree of opening calculated by the calculation unit. The calculation unit corrects, in high-pressure purge performed when a pressure in the fuel tank increases exceeding a predetermined pressure, the degree of opening using a tank pressure flow velocity correction coefficient K2 corresponding to an upstream pressure of the purge valve.

摘要： A fuel injection control apparatus is included in an internal combustion engine including an intake passage injection valve and a cylinder injection valve and being capable of switching between an MPI mode and a DI+MPI mode based on an operating state of the engine. The fuel injection control apparatus includes an injection amount control unit including a direct-combustion-rate calculation unit calculating a DI direct combustion rate that is the rate of that portion of the amount of DI injection which corresponds to a fuel combusted instead of adhering to inside of the cylinder, and a cylinder vaporization rate calculation unit calculating a cylinder vaporization rate that is the rate of the amount of that portion of the fuel adhering to the inside of the cylinder which vaporizes. The injection amount calculation unit controls fuel injection based at least on the DI direct combustion rate and the cylinder vaporization rate. When the engine is switched between the MPI mode and the DI+MPI mode, the injection amount calculation unit corrects the DI direct combustion rate or the cylinder vaporization rate to set the amount of fuel injection to a value different from a value set in a case where the fuel injection modes are maintained.

摘要： The control apparatus for an engine includes: a first controller that sets a valve-opening timing of an intake valve of the engine in response to an amount of intake air; and a second controller that sets an injection start time of a fuel injector of the engine in response to the amount of intake air. In a case where the amount of intake air is within a first range being equal to or more than a predetermined value, the first controller advances the valve-opening timing as compared with a case where the amount of intake air is equal to the predetermined value, and the second controller delays the injection start time as compared with a case where the amount of intake air is within a second range being less than the predetermined value.
