Patent number: 10724420Abstract: An exhaust device for an engine is disposed beneath a loading platform at a position rearwardly of a seat of a utility vehicle. A plurality of exhaust pipes extend rearwardly from a front surface of an engine main body by way of one lateral side of the engine main body. The plurality of the exhaust pipes are collected by a single collecting tube. An exhaust conduit extends from the collecting tube in a direction rearwardly of the engine. A muffler is disposed in a rear portion of the vehicle and fluid connected with a downstream end of the exhaust conduit. The exhaust pipes, the collecting tube and the exhaust conduit are covered by a covering. The covering is fitted to the exhaust pipes and the exhaust conduit to thereby suppress a heat conduction from the exhaust pipes, the collecting tube and the exhaust conduit.Type: GrantFiled: November 13, 2018Date of Patent: July 28, 2020Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Makoto Momosaki, Jun Takagi, Koutarou Hanabusa

Patent number: 8006488Abstract: An exhaust system for a motorcycle provided with a multicylinder engine, includes an exhaust aggregating member for unifying a pair of exhaust passages, through which an exhaust gas exhausted from the engine is transported to a muffler, so as to form a single exhaust passage therein. The single exhaust passage is connected to the muffler without being merged with another exhaust passage. The exhaust system also includes an exhaust control valve incorporated into the exhaust aggregating member and capable of changing sectional area of the single exhaust passage formed in the exhaust aggregating member.Type: GrantFiled: September 7, 2004Date of Patent: August 30, 2011Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Makoto Momosaki, Hisatoyo Arima

Patent number: 7713494Abstract: Disclosed is an exhaust purification device in which an entire length of an outer cylinder of a catalyst can be used effectively for exhaust purification and it is possible to prevent heat in fixing of the catalyst to an exhaust pipe from affecting a connection portion between the outer cylinder and catalyst main bodies. A catalyst includes an outer cylinder and a plurality of catalyst main bodies provided in the outer cylinder in a state of being spaced each other in a direction of an axial center of the outer cylinder. An outer face of the outer cylinder positioned between the catalyst main bodies is a fixed face to be fixed to an inside of the exhaust pipe.Type: GrantFiled: September 11, 2006Date of Patent: May 11, 2010Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Satoaki Ichi, Makoto Momosaki

Patent number: 6764277Abstract: A fan guard 18 of an outdoor unit comprises an outer frame, a plurality of radiating ribs 27, and a plurality of annular ribs 28. The outer frame is disposed around the outer circumference of a lid member that is an air conditioner discharge port. The plurality of radiating ribs 27 are formed such that they radiate in the outer radial direction from the vicinity of the center of the outer frame 26 to the outer frame 26, and are curved in the rotational direction of a ventilation fan. The plurality of annular ribs 28 are integral with the radiating ribs 27, are concentrically disposed at a predetermined spacing in the radial direction around the center of the rotational axis of the ventilation fan, and are formed such that at least those in an outer circumference are slanted toward the outer radial direction to follow the flow of the air blown from the ventilation fan.Type: GrantFiled: October 8, 2002Date of Patent: July 20, 2004Assignee: Daikin Industries, Ltd.Inventors: Koji Somahara, Toshihiko Takayama, Makoto Momosaki
