Patent number: 5094212Abstract: A throttle body assembly for supplying a mixture of fuel and air to an intake port of an internal combustion engine, integrally incorporating a fuel injection valve, a fuel pump, a fuel supply passage defined in the throttle body and extending from the fuel pump to the fuel injection valve, and a fuel pressure control valve directly incorporated in the throttle body to control pressure of fuel in the fuel supply passage. Thus, there is no need to use an external tubing system for supplying and returning fuel to and from the fuel injection valve, and the throttle body assemby may be simplified in structure so as to facilitate the assembling and servicing of the throttle body assembly. Further, an electronic control unit and sensors associated with the control unit are both directly mounted on the throttle body so that wiring around the throttle body may be eliminated.Type: GrantFiled: March 28, 1990Date of Patent: March 10, 1992Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yuji Kawaguchi, Tomio Aoi, Kiyohide Nagase, Yoshio Suzuki, Yasuhiro Toyoda, Toshihiro Kameda, Hiroshi Hashimoto, Isao Murakami, Akihiro Iwasaki
