摘要： Muffler connected to the exhaust-discharging end of an engine is positioned above the engine adjacent a fuel tank. Heat blocking cover covers top and side portions of the muffler, and a fan cover, generally in the shape of a cylinder and extending close to the engine, covers an electric-power generator. Cooling fan device is provided in a cooling-air inlet portion of the fan cover for introducing cooling air from the outside to the electric-power generator covered with the fan cover. Engine-cooling air passage having a cooling-air inlet portion that faces a cooling-air outlet portion of the fan cover is provided to cool an outer surface of the engine by the cooling air flowing out through the cooling-air outlet portion of the fan cover. The engine-cooling air passage is branched upward to provide a separate muffler-cooling air passage extending between the muffler and the heat blocking cover above the engine. Thus, the cooling air introduced from the outside is allowed to cool both the engine and the muffler after having cooled the electric-power generator. With such arrangements, the engine, generator and muffler can be cooled with enhanced efficiency in a very simple manner.

摘要： An engine generator is disclosed in which an engine drives a generator and causes a cooling fan to rotate to cool the generator. The generator includes an intake duct having an intake port provided in a lower portion thereof and oriented downward. Moisture-containing outside air sucked through the intake port impinges on a barrier plate disposed in the intake duct. The barrier plate is located above the intake port and faces the intake port. The moisture adheres to the barrier plate in the form of water droplets, which then fall toward the intake port after having separated from the outside air.

摘要： An engine generator comprises a fan cover made of die-cast aluminum alloy, and a power control unit including an aluminum base sheet. The base sheet has a power control circuit formed thereon. The fan cover includes a mounting portion to be attached to the power control unit. When the power control unit is attached to the fan cover, a surface of the aluminum base sheet comes into intimate contact with an outer surface of the mounting portion. Heat generated at the unit is transmitted to the fan cover, and then released from the fan cover serving as a heat releasing member.

摘要： An engine operated working machine includes an engine and a working machine to be driven by the engine surrounded by a soundproof case. An exhaust compartment housing a muffler is formed in the soundproof case. An exhaust pipe connected with the muffler is bent in a direction so as to direct exhaust gas discharged therefrom away from an exhaust air opening of the exhaust compartment and has an opening positioned apart from the exhaust air opening. Cooling air forced into the exhaust compartment flows around the muffler and the exhaust pipe to cool them. Exhaust gas discharged from the exhaust pipe into the exhaust compartment is mixed with the cooling air to change a discharging direction thereof and is then discharged outside of the soundproof case through the exhaust air opening.
