Patent number: 11131230Abstract: There is provided an exhaust treatment device for a diesel engine capable of accurately estimating an amount of ash deposition. In the exhaust treatment device, an ash deposition estimation device estimates an amount of ash deposition on a DPF after ending of regenerating treatment for the DPF, based on data regarding differential pressure and exhaust flow rate stored in a memory device over a period immediately before the end of regeneration, the period ranging from the end point of regenerating treatment for the DPF to a point in time going back a predetermined duration. An electronic control device preferably makes an alarm device issue an alarm, upon arrival of an estimated value of ash deposition at a predetermined alarm request value.Type: GrantFiled: June 5, 2019Date of Patent: September 28, 2021Assignee: KUBOTA CORPORATIONInventors: Katsushi Inoue, Masanori Fujiwara, Hiroaki Okano

Patent number: 10619546Abstract: There is provided an exhaust treatment device for a diesel engine that can prevent unnecessary alarm for ash deposition from being issued. In the exhaust treatment device, a timer measures integrated time of a state of non-regenerative operation which ranges from an end of DPF regeneration to a next time point where the differential pressure reaches a regeneration request value. A counter acquires the short interval count if the integrated time is a short interval shorter than a predetermined decision time. An alarm device issues an alarm if the consecutive short interval count reaches a predetermined plural necessary count for alarm. A short interval count having been already acquired is preferably reset to 0 if the integrated time of the state of non-regenerative operation is a long interval, not shorter than a predetermined decision time, before the short interval count reaches the predetermined necessary count for alarm.Type: GrantFiled: April 23, 2019Date of Patent: April 14, 2020Assignee: KUBOTA CorporationInventors: Katsushi Inoue, Koichi Funaki, Masanori Fujiwara, Tamotsu Kuno, Kentaro Kita, Yuki Yoshita

Patent number: 9458753Abstract: The present invention provides a diesel engine capable of preventing a PM accumulation amount from increasing excessively. If DOC inlet exhaust gas temperature (“IEGT”) does not reach a predetermined value T0, a control unit carries out air intake amount feedback control (“AIAFC”), and a target value of intake throttling is set to a predetermined air intake amount. If the DPF regenerating processing is not started even if elapsed time reaches a predetermined value t after AIAFC is started in a state where the DOC IEGT does not reach the predetermined value T0, the control unit changes AIAFC to exhaust gas temperature feedback control (“EGTFC”). In EGTFC, the control unit changes a target value of intake throttling to a predetermined DOC IEGT T0. If application of a load exceeding a predetermined amount is detected before the DOC IEGT reaches the predetermined value T0, the control unit returns EGTFC to AIAFC.Type: GrantFiled: September 5, 2014Date of Patent: October 4, 2016Assignee: KUBOTA CorporationInventors: Kentarou Kita, Tamotsu Kuno, Katsushi Inoue, Yuuji Takemura, Yuuki Ishii, Yusuke Komemushi, Tomoya Hasegawa
