摘要： An exhaust gas purification system is equipped with a burner in an exhaust passage upstream of an exhaust gas purification apparatus and having a burner combustion chamber in which flame is produced. When the temperature of the exhaust gas purification apparatus is raised, the burner produces flame that extends from the interior of the burner combustion chamber to the interior of the exhaust passage when the flow rate of the exhaust gas is not higher than a predetermined flow rate, and the burner causes the size of the flame to be smaller than when it is determined that the flow rate of the exhaust gas is not higher than the predetermined flow rate or to produce flame only in the interior of the burner combustion chamber when it is determined that the flow rate of exhaust gas is higher than the predetermined flow rate.

摘要： 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.

摘要： An exhaust purification catalyst (11) for purifying NOx under a lean air-fuel ratio is arranged in exhaust passage of an internal combustion engine. As a catalyst carrier (50) of this exhaust purification catalyst (11), alumina, which has base points on the carrier surface, is used. The surface of the alumina is made to carry platinum (51) dispersed on it without forming a layer of a NOx absorbent able to absorb NOx. The air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (11) is temporarily switched from lean to rich before the entire surface of the platinum (51) suffers from oxygen poisoning.

摘要： The present invention is a vehicle body conveying apparatus in which a vehicle body (20) conveyed by a shuttle conveyor (32) is then conveyed in the order of an inclining belt conveyor (1) and a slat conveyor (21). A miniconveyor (26) is disposed between the inclining belt conveyor (1) and the slat conveyor (21) in such a relation that a rear end of the miniconveyor (26) overlaps a delivery side of the inclining belt conveyor (1), and the front end overlaps a receiving side of the slat conveyor (21) so as to ensure smooth transfer of the vehicle body (20) between them. Further, the inclining belt conveyor (1) is inclined by an elevating mechanism (8) to separate the vehicle body (20) from the shuttle conveyor (32).

摘要： An exhaust gas purification system for an internal combustion engine is provided with a filter including a selective catalytic reduction NOx catalyst carried thereon. Further, a post-catalyst is provided for an exhaust gas passage disposed on a downstream side from the filter. The post-catalyst has an oxidizing function, and the post-catalyst has such a function that the production of N2 based on the oxidation of ammonia is facilitated in a predetermined first temperature area. A filter regeneration process execution unit is programmed to control the temperature of the post-catalyst to be in the first temperature area while adjusting the temperature of the filter to be in a predetermined second temperature area lower than a filter regeneration temperature during a certain period of time.
