Patent number: 9297287Abstract: An exhaust gas control apparatus includes a control device controlling a urea addition valve for adding urea from an upstream side of a NOx reduction catalyst. The control device obtains an ammonia adsorption amount distribution through the NOx reduction catalyst. When an ammonia adsorption amount in a predetermined part on a downstream side equals or exceeds a predetermined threshold, the control device controls the urea addition valve to stop the urea supply or reduce the amount thereof. The urea addition valve is controlled based on an adsorption amount distribution obtained from a model on which the catalyst is divided into cells such that an ammonia adsorption amount in a first cell positioned furthest upstream equals or exceeds a predetermined threshold close to a saturation adsorption amount and an ammonia adsorption amount in a second cell positioned downstream of the first cell reaches a predetermined target value smaller than the threshold.Type: GrantFiled: September 21, 2011Date of Patent: March 29, 2016Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, DENSO CORPORATION, KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Shinya Hirota, Shunsuke Toshioka, Akira Mikami, Koichiro Fukuda, Sakutaro Hoshi, Takashi Endo, Ryoichi Hibino, Matsuei Ueda, Akihiko Asano, Takafumi Yamauchi, Akira Shichi, Makoto Koike, Masatoshi Maruyama, Masakazu Sakata
