Patent number: 11953116Abstract: A valve body has an inflow passage for a working fluid, an outflow passage for the working fluid, and a pressure relief passage, which connects the inflow passage and the outflow passage by bypassing a normally close valve seat. A pressure relief valve is located in the pressure relief passage. The pressure relief valve closes the pressure relief passage, if a pressure of the working fluid in the outflow passage is lower than, is equal to, and is higher by a pressure difference less than a predetermined relief pressure than a pressure of the working fluid in the inflow passage. The pressure relief valve opens the pressure relief passage, if the pressure of the working fluid in the outflow passage is higher by a pressure difference equal to or higher than the relief pressure than a pressure of the working fluid in the inflow passage.Type: GrantFiled: September 8, 2022Date of Patent: April 9, 2024Assignee: HAMANAKODENSO CO., LTD.Inventors: Fumiaki Kaneko, Masashi Sugano, Yutaka Sato, Masahiro Hisada

Publication number: 20240068422Abstract: An upstream integrated value is an integrated value of a difference obtained by subtracting an upstream gas temperature at a starting point in time of integration from the upstream gas temperature after starting of the internal combustion engine. A downstream integrated value is an integrated value of a difference obtained by subtracting a downstream gas temperature at the starting point in time of the integration from the downstream gas temperature after the starting of the internal combustion engine. An anomaly diagnosing process obtains an anomaly determination result indicating that the exhaust purification device is in a removed state when a deviation between the upstream integrated value and the downstream integrated value is smaller than a reference level. The determination threshold is higher than a dew point.Type: ApplicationFiled: July 21, 2023Publication date: February 29, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yusuke JOH, Tomoyuki TSUJI, Yuki IKEJIRI, Masashi HAKARIYA, Makoto YAMAZAKI, Yoshikazu ASAMI, Hisao KIYONO, Tatsuaki ARISAWA, Yoshifumi MATSUDA, Tsubasa SUGANO
