摘要： Provided is a control apparatus for an internal combustion engine that can favorably achieve compatibility between suppressing deterioration of a catalyst and suppressing progression of rich poisoning thereof when the internal combustion engine has a configuration that performs valve stopping control during a fuel-cut operation. Variable valve operating apparatuses are provided having valve stop mechanisms that can respectively change an operating state of an intake valve and an exhaust valve between a valve operating state and a closed-valve stopped state. When an integrated fuel injection amount is equal to or greater than a predetermined value β when executing a fuel-cut operation, it is determined that rich poisoning of an upstream catalyst is in a progressed state. In that case, valve stopping control of the intake and exhaust valves is prohibited to thereby supply oxygen to the upstream catalyst.

摘要： An engine includes an intake variable valve mechanism and an exhaust variable valve mechanism. An ECU causes all intake valves in all cylinders to stop in a closed state by means of intake variable valve mechanism when performing a fuel-cut operation, including when the engine is stopped. The ECU causes at least one exhaust valve in all cylinders to stop in an open state by means of exhaust variable valve mechanism. When executing a fuel-cut operation, needless compression can be avoided by stopping the exhaust valves in an open state, while protecting a catalyst from deterioration caused by contact with intake air by stopping the intake valves in a closed state. The amount of oil consumption of the engine, and electric power consumption, vibrations and a tendency for spontaneous ignition to occur at cranking time can be improved.

摘要： There is provided a control apparatus for an internal combustion engine, which can favorably reduce a load necessary for cranking at the time of the next start, while preventing the fresh air inflow to a catalyst at the time of the stop of the internal combustion engine. A valve stop command is issued to an electrically-driven actuator so that the operational states of intake and exhaust valves becomes a valve closed/stopped state when fuel supply is stopped in response to an establishment of a predetermined stop condition of the internal combustion engine. Then, to return the operational states of the intake and exhaust valves to a valve operating state after the completion of the stopping operation of the internal combustion engine, a valve return command is issued to the actuator, and a crankshaft is rotationally driven by a predetermined angle required to return the operational states of the intake and exhaust valves to the valve operating state.
