    • Provided is a control apparatus for an internal combustion engine, which can determine whether or not there is a failure concerning a switching of an operational state of an intake valve, in the internal combustion engine that includes a valve stop mechanism that is capable of switching the operational state of the intake valve between a valve operating state and a valve closed/stopped state, without the need of adding a new sensor for the failure determination. An intake variable valve operating apparatus (66) is provided that includes a valve stop mechanism capable of switching the operational state of the intake valve (62) between the valve operating state and the valve closed/stopped state. A crank angle sensor (72) is provided for detecting the crank angle of the internal combustion engine (12). An intake pressure sensor (56) is provided for detecting the actual intake pressure pim. It is determined whether or not there is a failure concerning the switching of the operational state of the intake valve (62) between the valve operating state and the valve closed/stopped state by the valve stop mechanism, based on an intake pressure difference dlpm (first difference) between the actual intake pressure pim and the pseudo intake pressure pmcrt at a predetermined crank angle (for example, 60° CA after the top dead center in each cylinder).

    • A control apparatus for an internal combustion engine is provided, which is capable of suppressing deterioration of exhaust emission due to an unburned fuel contained in oil which enters a combustion chamber during valve stop control while preventing inflow of fresh air to a catalyst, at a time of valve return following return from fuel cut. Variable valve operating apparatuses having valve stop mechanisms capable of changing operation states of an intake valve and an exhaust valve between valve operation states and valve closed and stopped states are included. Valve stop control that changes the operation states of the intake valve and the exhaust valve to the valve closed and stopped states is performed, at a time of execution of the fuel cut. When a return request from the fuel cut with the valve stop control is detected, a fuel is supplied to a combustion chamber before the operation state of the exhaust valve is returned to the valve operation state. The fuel supply amount in this case is corrected in accordance with an amount of the unburned fuel contained in the oil which enters into the combustion chamber from a crank chamber side during the fuel cut with the valve stop control.
    • 提供了一种用于内燃机的控制装置,其能够抑制在停止控制期间进入燃烧室的油中包含的未燃烧燃料的废气排放的劣化,同时防止新鲜空气一次流入催化剂 从燃油切断返回后阀门返回。 包括具有能够改变阀操作状态和阀关闭和停止状态之间的进气门和排气阀的操作状态的阀停止机构的可变气门操作装置。 在执行燃料切断时,执行将进气门和排气阀的运行状态改变为阀关闭和停止状态的阀停止控制。 当检测到具有阀停止控制的燃料切断的返回请求时,在排气阀的操作状态返回到阀操作状态之前,向燃烧室供给燃料。 在这种情况下的燃料供给量根据在阀停止控制的燃料切断期间从曲轴室侧进入燃烧室的油中所含有的未燃烧燃料的量进行校正。

    • Valve stopping control is performed that changes an operating state of an intake valve and an exhaust valve to a closed-valve stopped state when executing a fuel-cut operation. A device is provided that sets an in-cylinder return-time target air-fuel ratio for an initial two return cycles when returning from a fuel-cut operation. The return-time target air-fuel ratio is set so that respective air-fuel ratios of air-fuel mixtures of fuel and air injected into the same cylinder for respective cycles during the initial return cycles each become values that fall within a combustible range, and so that even if a total amount of fuel injected into the same cylinder for the initial return cycles is supplied into the cylinder during an arbitrary single cycle, the air-fuel ratio of the air-fuel mixture of the total amount of fuel and air becomes a value that falls within the combustible range.
