摘要： 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.

摘要： A duct member is disposed around outer peripheries of an engine and an engine-driven generator to define a continuous cooling-air passage between the duct member and the outer peripheries. A cooling fan is disposed in the cooling-air passage to generate a flow of cooling air from one end of the cooling-air passage to the other end during operation of the engine. An intake box is connected to one end of the cooling-air passage and has an air-intake port. A muffler box is connected to the other end of the cooling-air passage, has an air-discharge port, and accommodates an exhaust muffler of the engine. A sound-insulating housing is connected between the intake box and the muffler box to surround the duct member in order to insulate sound emitted from the duct member.

摘要： 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.
