摘要： The present invention has its object to provide a control apparatus for an internal combustion engine including a variable valve operating mechanism which is capable of accurately and effectively identifying an abnormality-occurring cylinder during operation while preventing the deterioration of a catalyst. A fuel injection valve 26 which is capable of injecting fuel for each cylinder is provided. Variable valve operating mechanisms 18 and 20 which is capable of halting the operation of the intake and exhaust valves in the closed state for each cylinder are provided. An abnormality evaluation index value is acquired during the operation of the internal combustion engine 10 and, based on the abnormality evaluation index value, an abnormality which has occurred in at least one cylinder in the internal combustion engine is detected. When the abnormality is detected, a cylinder halting to perform the halting of fuel supply and the halting of the valve operation in the closed state is executed with a first partial cylinder made up of at least two cylinders as the target. After the cylinder halting, with the cylinder to be halted being changed, a cylinder halting is executed with a second partial cylinder made up of at least one cylinder as the target. Based on the change in the abnormality evaluation index value associated with the changing of the cylinder to be halted, the abnormality-occurring cylinder is identified.

摘要： An object of the present invention is to provide an abnormality detection device that is used with an internal combustion engine having a valve drive mechanism capable of halting the drive of at least one of an intake valve and an exhaust valve, and able to detect the abnormalities of a valve drive halt function. The internal combustion engine includes a knock sensor capable of sensing the seating sound of the intake valve and/or the exhaust valve. An ECU detects whether a control signal given to the valve drive mechanism is a valve drive signal or a valve halt signal. In accordance with the result of detection by the ECU and the presence of the seating sound in an output of the knock sensor, the abnormality detection device judges whether or not the valve drive mechanism is abnormal.

摘要： Two types of cells (first cells (12) and second cells (14)) are used to constitute a honeycomb structure. The first cells (12) and second cells (14) differ in the catalyst supporting position. The first cells (12) and second cells (14) are alternately arranged. The catalyst supporting position of the second cells (14) is shifted in the direction of the downstream side of the flow of an air-fuel mixture from the catalyst supporting position of the first cells (12) so that when an exothermic reaction occurs on the second cell side of a partition wall (10) for separating a first cell (12) from a second cell (14), an endothermic reaction occurs on the opposing first cell side of the partition wall (10).

摘要： When, for example, a predetermined operating condition such as a fuel cut operating condition is satisfied (time-point tfc), an air-fuel ratio imbalance among cylinder determining apparatus sequentially stops a fuel injection for each of cylinders in accordance with a firing (ignition) order, and changes intake valves and exhaust valves of the cylinder whose fuel injection is stopped from a valve operating state to a valve resting state. Consequently, after a time-point at which an exhaust gas (final gas) is discharged from a cylinder into an exhaust passage (the exhaust gas being generated from a fuel injected lastly for that cylinder), no new gas is discharged from that cylinder. Accordingly, when a predetermined time elapses (time-point tp), an upstream-side air-fuel ratio abyfs obtained based on an output value of an upstream air-fuel ratio sensor disposed in the exhaust passage becomes a value corresponding to an air-fuel ratio of the final gas. The determining apparatus obtains that value as data relating to an air-fuel ratio of the cylinder which discharged the final gas, and determines whether or not an air-fuel ratio imbalance is occurring based on the data relating to the air-fuel ratio of each of the cylinders.

摘要： A gas detection device includes: an element portion (40); a voltage applying unit (81) configured to apply a voltage (step-up, maintaining voltage constant at a voltage higher than the decomposition start voltage of sulfur oxides, step-down) across a first electrode (41a) and a second electrode (41b) on surfaces of a solid electrolyte (41s); a current detecting unit (91) configured to detect an output current flowing between the first electrode (41a) and the second electrode (41b); and a measurement control unit (20). The measurement control unit (20) acquires a parameter which has a correlation with a degree of change of the output current increasing as a concentration of sulfur oxides in an exhaust gas increases based on the output current during the voltage step-down, and performs determination of whether the concentration of sulfur oxides in the exhaust gas is equal to or higher than a predetermined value or detection of the concentration of sulfur oxides in the exhaust gas based on the acquired parameter.
