Patent number: 8307636Abstract: To suppress clogging of an injection nozzle that supplies fuel to an exhaust passage of an engine, a controller executes intermittent addition of fuel from the injection nozzle. In executing the intermittent addition, the controller calculates a particulate discharge amount within the exhaust passage based on the engine operation state, and multiplies the exhaust gas temperature by the intake air rate to calculate the exhaust energy. Then, based on the particulate discharge amount and the exhaust energy, the controller calculates the amount of fuel to be added.Type: GrantFiled: October 20, 2008Date of Patent: November 13, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventor: Yasuhiro Matsunaga
