Patent number: 8850799Abstract: Based on a fuel supplying amount in accordance with an engine operating condition, a discharge amount of a predetermined fuel component contained in exhaust gas to be discharge per unit time is estimated, and integrated by an accumulation amount of the fuel component accumulated in an exhaust purification element. Furthermore, according to an exhaust gas temperature that flows into the element, an amount of the fuel component to be removed from the element per unit time is estimated, and the amount is subtracted from the accumulation amount. When the accumulation amount is equal to or greater than a predetermined value, a determination is made that a timing to forcefully remove the fuel component accumulated in the element has arrived. Then, an alarming lamp is lightened, and a forceful removing processing is performed by raising a temperature of the exhaust gas above a temperature at which the fuel component is removed.Type: GrantFiled: October 5, 2012Date of Patent: October 7, 2014Assignee: UD Trucks CorporationInventors: Masakazu Yano, Tomofumi Nakashima, Tomoyuki Takeda, Takafumi Amano

Patent number: 8790219Abstract: In order to maintain a high NOx purification rate of a NOx reduction catalytic converter even in the case in which an NOx emission amount from an engine changes suddenly, in an exhaust emission purifying apparatus for an engine that reduces and purifies NOx in exhaust gas using ammonia generated from an injection-supplied urea aqueous solution, after engine starting, when an exhaust temperature exceeds a predetermined temperature T (step S1), an amount of urea aqueous solution corresponding to an actual engine operating state is injection-supplied (steps S3 to S5). On the other hand, at a change of the transmission speed ratio based on a driver's shift operation, an engine operating state after the change of the transmission speed ratio is predicted (steps S2, S6), and an amount of urea aqueous solution corresponding to the predicted engine operating state is injection-supplied before the change of the transmission speed ratio is completed (steps S7, S8).Type: GrantFiled: June 17, 2011Date of Patent: July 29, 2014Assignee: UD Trucks CorporationInventors: Masakazu Yano, Kiminobu Hirata, Nobuhiko Masaki
