  • Apparatus for detecting deterioration of NOx selective reduction catalyst
    Patent number: 9594065
    Abstract: Apparatus for detecting deterioration of an NOx selective reduction catalyst in an exhaust passage of an internal combustion engine with improved accuracy, includes an NOx purification rate calculation unit for calculating the NOx purification rate in the NOx selective reduction catalyst based on the NOx concentration in the exhaust gas flowing into and out of the NOx selective reduction catalyst. A determination as to whether the NOx selective reduction catalyst is deteriorated is made based on the NOx purification rate at a time when the temperature of the NOx selective reduction catalyst is equal to or higher than a temperature (Tc0) at which the NOx purification rate will start to decrease with a rise in the temperature of the NOx selective reduction catalyst if the degree of deterioration of the NOx selective reduction catalyst is at the upper limit of an allowable range.

    Publication number: 20170041488
    Abstract: An information processing apparatus is configured in the following manner. When a client is connected to a server, the client transmits all of setting information that the client handles as a synchronization target to the server. The server returns an error response to prohibit synchronization in response to transmission of a setting item that the server does not handle as the synchronization target among the setting information transmitted from the client. After that, the client apparatus does not notify the server of a content of an update with respect to the setting information of the setting item to which the error response is returned when the client is connected to the server.
