Patent number: 9890683Abstract: It is an object to make it possible to burn and remove particulate matter without generating runaway even if the particulate matter is excessively accumulated at the time of regeneration of an exhaust gas purification device. A common rail engine and the exhaust gas purification device placed in an exhaust gas path of the engine are provided. A plurality of regeneration controls for burning and removing the particulate matter accumulated in the exhaust gas purification device can be executed. The plurality of regeneration controls include at least non-operation regeneration control for raising exhaust gas temperature by combining post injection (E) and predetermined high speed rotation speed, and recovery regeneration control which can be executed when the non-operation regeneration control fails. In the non-operation regeneration control and the recovery regeneration control, the engine is driven exclusively for burning and removing the particulate matter.Type: GrantFiled: March 26, 2014Date of Patent: February 13, 2018Assignee: Yanmar Co., Ltd.Inventors: Hideo Shiomi, Tomohiro Fukuda, Atsushi Ohta
