    摘要： A torsional vibration damper assembly having stable torsional vibration damping characteristics is provided. The damper assembly comprises an input element, an output element, a damper hub operatively connected to the output element and having a plurality of circumferentially spaced, radial hub arms, a drive plate operatively connected to the input element and having a plurality of circumferentially spaced windows, a plurality of compression springs extending between circumferentially opposed edges of the windows and the hub arms, and a ring member rotatable relative to the input and output elements and surrounding the compression springs for restricting radially outward bending of the compression springs. Since the ring member is not urged against its surrounding constituent parts of the damper assembly when it is subjected to a centrifugal force of itself and a centrifugal force of the compression springs, the damper assembly can provide stable torsional vibration damping characteristics.

    摘要： A reduction in the accuracy of a failure determination of a filter due to a reduction in the detection accuracy of a PM sensor is suppressed. In order to achieve this, provision is made for a filter that is arranged in an exhaust passage of an internal combustion engine for trapping particulate matter contained in an exhaust gas, an NOx selective reduction catalyst that is arranged at the downstream side of the filter and reduces NOx by means of a reducing agent which is supplied thereto, a supply device that supplies the reducing agent to the NOx selective reduction catalyst from the upstream side of the NOx selective reduction catalyst, a PM sensor that detects an amount of the particulate matter in the exhaust gas at the downstream side of the NOx selective reduction catalyst, and a prohibition part that prohibits the use of a detected value of the PM sensor in cases where the reducing agent supplied from said supply device passes through the NOx selective reduction catalyst.

    摘要： An object of the invention is to prevent a situation in which failure diagnosis for an exhaust system component in an internal combustion engine cannot be completed from continuing for an unduly long period of time. A warm-up system for an exhaust system of an internal combustion engine according to the invention includes a warm-up control performing unit that performs warm-up control for warming up an exhaust system component upon start-up of the internal combustion engine and a failure diagnosis performing unit that performs failure diagnosis for the exhaust system component after the completion of warm-up of the exhaust system component. If a situation in which the operation of the internal combustion engine is stopped after the start of operation of the internal combustion engine before the completion of the failure diagnosis for the exhaust system component performed by the failure diagnosis performing unit has been repeated for a predetermined period of time, the warm-up control performing unit changes the warm-up control performed upon start-up of the internal combustion engine after the predetermined period of time has elapsed to a control that can raise the temperature of the exhaust system component more quickly than the warm-up control performed during the aforementioned predetermined period.

    摘要： An object of the present invention is to provide a technology that enables detection of a fault of a PM trapper with improved accuracy. In the present invention, a pressure sensor 20 that measures a differential pressure across a PM trapper 11 is provided, and a fault of a PM trapper is determined based on an amount of change in the differential pressure across the PM trapper 11 between two different operation states of an internal combustion engine 1 in which the ambient temperature around the pressure sensor 20 falls within a specific temperature range. Since variations in the offset error of the differential pressure sensor 20 caused by changes in the ambient temperature around the differential pressure sensor 20 is made small, the amount of change in the differential pressure across the PM trapper 11 can be measured more accurately, and a fault of the PM trapper 11 can be detected with improved accuracy.
