Patent number: 8328207Abstract: An engine generator movable on left and right wheels. The wheels are provided on a rear section of a bottom cover via an axle. A cylinder of an engine is disposed so as to incline upwards towards the direction of the axle. Inclining the cylinder lowers the center of gravity of the engine and disposes the axle positioned below the cylinder at a high position, thereby reducing the height of the engine generator. The orientation of the engine generator during travel is stabilized.Type: GrantFiled: June 24, 2009Date of Patent: December 11, 2012Assignee: Honda Motor Co., Ltd.Inventors: Tadafumi Hirose, Masanori Shin, Makoto Uchimi, Takayuki Aoki

Patent number: 8210133Abstract: Engine cooling structure directs cooling air, introduced into a case by operation of a fan, to a cylinder block of an engine and then discharges the cooling air out of the case through an outlet port along meandering flow passages. Case cooling structure directs cooling along the inner surface of the case. Further cooling flow passage directs the air to vertically-oriented heat radiating fins so that the cooling air flows upward along the fins and then is discharged through the outlet port. Metal cooling-fan cover is supported by the lower cover via mounting members, and a resin-made cover guide is fastened to the engine together with supporting portions and interposed between the fan cover and the engine.Type: GrantFiled: June 16, 2009Date of Patent: July 3, 2012Assignee: Honda Motor Co., Ltd.Inventors: Tadafumi Hirose, Hitoshi Yuki, Takayuki Aoki, Ryosuke Shibata, Hiroki Iikura, Makoto Uchimi, Masashi Kai
