Title: Catalyst deterioration diagnosis device for engine
Inventor: ISHIHARA KOJI
IPC: F01N11/00
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To accurately diagnose deterioration in NOx absorbing performance by diagnosing deterioration of NOx absorbing performance from correlation between responsive delay of change from lean to rich across NOx absorbing catalyst and a NOx absorbed quantity up to the change to be rich. SOLUTION: At judging realization of a lean combustion condition, a NOx absorbing quantity detecting means B estimatedly computes the NOx absorbed quantity of NOx absorbing catalyst from the operating condition of an engine. An air-fuel ratio increasing means C inverts the air-fuel ratio from lean to rich, when the estimatedly computed NOx absorbed quantity reaches the saturated quantity, and a fuel injection quantity is corrected to increase for performing separation and reduction of the absorbed NOx. Hereat a delay time measuring means D measures a time since the exhaust air-fuel ratio before the catalyst is detected to be inverted to rich by an oxygen sensor on the upper stream side, until delayed inversion to rich after the catalyst is detected by an oxygen sensor on the down stream side.  A catalyst deterioration detecting means E judges deterioration of NOx absorbing performance, when delay of a time corresponding to the estimated NOx absorbed quantity is not in the measured delay time.

If the judgment is NO, which of cooling, heating and dehumidifying modes the operation mode information at the time of stopping is judged by using a memory means 2 for storing the information at the time of stopping. For example, if the mode at the time of stopping is the cooling, when a detected room temperature of a room temperature sensor 4 is in a lower temperature area than a lower temperature side set temperature, the heating mode is selected, or when it is in a higher temperature area than a high temperature side set temperature, the cooling mode is selected.

Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To connect smoothly recovered parts from an error compensation frame by storing amplitude coefficient data of a final block of one frame and comparing the data with an amplitude coefficient of a first block of a frame succeeding to a frame where errors take place to set a required amplitude. SOLUTION: A (fn+1)-th frame of a compressed audio stream is received in an audio stream AFLM(fn+1) input step. An error detection code EDC 110 or the like is used to detect presence of an error and the result is stored in a way that the frame numbers of erroneous frames are recognized. Whether or not a (fn)-th frame has been an erroneous frame is confirmed in the AFLM (fn) error confirmation step. In the case that the frame has no error, an amplitude is reproduced based on data EXP 113 relating to amplitude data from information included in the AFLM(fn) in the AFLM(fn) amplitude data reproduction step. Then a sample value RECON-SAMP s reproduced based on the reproduced amplitude and a MANT 114 included in the AFLM(fn). A final block ABLK(5) in the (fn)-th frame is stored.
