Patent number: 10865680Abstract: A reduction in measurement accuracy of a concentration sensor is minimized. An exhaust gas purifying device of a work machine includes a reduction catalyst that is placed in an exhaust flow passage of an exhaust gas of an engine and uses a reducing agent to reduce and purify nitrogen oxides in the exhaust gas, and a reducing agent injector to inject the reducing agent into the exhaust flow passage. The exhaust gas purifying device of a work machine includes: a storage unit that stores the reducing agent; a concentration sensor that has a sensing part placed within the storage unit to detect a concentration of the reducing agent; an air-bubble removal device that injects the reducing agent toward the sensing part; and a reducing agent pump that supplies the reducing agent in the storage unit to the air-bubble removal device.Type: GrantFiled: October 28, 2016Date of Patent: December 15, 2020Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Gen Yasuda, Takenori Hiroki, Ryou Takaichi, Hisashi Tago, Hironori Itou
