Patent number: 8307812Abstract: A vaporized-fuel processing device for an engine stabilizes the idling operation wherein vaporized fuel within a fuel reservoir is adsorbed to an adsorbing member of a canister. While the engine is in operation, air is sucked from an air inlet into the canister with the intake-air negative pressure produced in an intake-air passage. This air separates the vaporized fuel adsorbed to the adsorbing member of the canister. Purge gas resulting from mixing the vaporized fuel into the air is sucked from a purge-gas sucking port into the intake-air passage. A throttle valve is arranged in a throttle intake-air passage of a throttle body. An intake-air pipe is disposed intake-upstream of the throttle body and is communicated with the throttle intake-air passage. The intake-air pipe has a peripheral wall to which a purge-gas sucking pipe is detachably attached. The purge-gas sucking port is provided within the purge-gas sucking pipe.Type: GrantFiled: February 1, 2010Date of Patent: November 13, 2012Assignee: Kubota CorporationInventors: Hiroshi Inoue, Hiroyuki Tsuda, Yutaka Teruumi, Noriaki Kobayashi, Seiji Izuhara

Publication number: 20100199954Abstract: The present invention has an object to provide a vaporized-fuel processing device for an engine, capable of stabilizing the idling operation. In order to accomplish the above object, the vaporized fuel (9) within a fuel reservoir (5) is adsorbed to an adsorbing member of a canister (1). While the engine is in operation, the air (10) is sucked from an air inlet (3) into the canister (1) with the intake-air negative pressure produced in an intake-air passage (7). This air (10) separates the vaporized fuel (9) adsorbed to the adsorbing member of the canister (1). Purge gas resulting from mixing the vaporized fuel (9) into the air (10) is sucked from a purge-gas sucking port (8) into the intake-air passage (7). A throttle valve (14) is arranged in a throttle intake-air passage (13) of a throttle body (12). An intake-air pipe (15) is disposed intake-upstream of the throttle body (12) and is communicated with the throttle intake-air passage (13).Type: ApplicationFiled: February 1, 2010Publication date: August 12, 2010Applicant: KUBOTA CORPORATIONInventors: Hiroshi INOUE, Hiroyuki TSUDA, Yutaka TERUUMI, Noriaki KOBAYASHI, Seiji IZUHARA

Patent number: 7438047Abstract: The present invention concerns a multi-cylinder engine comprising a throttle body (5) in which a throttle intake-air passage (6) is provided. A throttle valve (7) is arranged in this throttle intake-air passage (6). Attached to the throttle body (5) is an injector (8), a leading end portion (9) of which is arranged opposite to an interior area of the throttle intake-air passage (6) downstream of the throttle valve (7) and is opened to provided a liquid-fuel injection hole (10). An intake-air pressure sensor (15) is attached to the throttle body (5) together with the injector (8) and an intake-air pressure introduction passage (18) has an inlet (18a) provided by opening an inner peripheral surface of the throttle intake-air passage (6) upstream of the injector (8).Type: GrantFiled: September 13, 2007Date of Patent: October 21, 2008Assignee: Kubota CorporationInventors: Takeshi Kawasaki, Yutaka Teruumi, Koji Fujimura, Hiroshi Inoue, Tetsushi Karasawa, Seiji Izuhara
