Patent number: 11002231Abstract: An intake device for an internal combustion engine configures a flow passage for intake air that is drawn into combustion chambers. The intake device includes an intake manifold configuring multiple runners that respectively distribute intake air to multiple cylinders, a surge tank including a cavity that is connected to the runners and defines a convergence portion, a throttle body incorporating a throttle valve, and a connection pipe connecting the surge tank and the throttle body and configuring a curved flow passage extending between the throttle body and the surge tank. The connection pipe includes a partition plate that divides the curved flow passage into a circumferentially inner flow passage and a circumferentially outer flow passage.Type: GrantFiled: October 1, 2019Date of Patent: May 11, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tadashi Ibaragi, Kazuaki Nakayama, Ako Itoh, Ryuji Koike, Toshiyuki Kondo

Publication number: 20160001259Abstract: A material for trapping a target substance, which is capable of selectively trapping a target substance such as a sludge or a sludge precursor contained in a liquid organic compound such as an engine oil or in a gas such as a blow-by gas (combustion gas). A material for trapping a target substance, which traps a target substance contained in a liquid organic compound or a gas, the material comprising a mesoporous inorganic material having a plurality of pores.Type: ApplicationFiled: September 11, 2015Publication date: January 7, 2016Inventors: Yasuhiro OHMIYA, Mamoru TOHYAMA, Hiroshi MORITANI, Narihito TATSUDA, Kazuhisa YANO, Kenichi HARADA, Ippei FUKUTOMI, Motoichi MURAKAMI, Norio INAMI, Ryuji KOIKE

Patent number: 8783223Abstract: The present invention is provided with a configuration which makes it possible to inhibit contact between an oil (L) and a gas in an oil pan (10a) properly. The oil pan (10a) according to the present invention contains a film (S1) which covers an oil surface (F) of the oil (L) to separate the stored oil (L) and the gas above the oil (L). The film (S1) can float by receiving buoyancy in the oil (L). The film (S1) may be formed of a liquid. The film also may be configured by a film member.Type: GrantFiled: April 30, 2009Date of Patent: July 22, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yukio Koseki, Motoichi Murakami, Norio Inami, Ryuji Koike
