音型エンジン発電機の排気ダクト構造。 The soundproof case that houses the engine and the generator driven by the engine is made of a steel plate with sound absorbing material attached to it, and outside air is taken into the soundproof case through the intake port, and a muffler is housed in the hot air inside the soundproof case. In the exhaust duct structure of a soundproof engine generator having a radiator fan for discharging the air from the exhaust port to the outside through the exhaust duct, a box-shaped partition member that covers the exhaust port of the radiator is housed in the exhaust duct. At the same time, the inside of the partition member is a first exhaust duct, the outside of the partition member is a second exhaust duct, and the first exhaust duct and the second exhaust duct are communicated with the lower end of the partition member and the lower part of the side wall. A vent is opened, a muffler is housed in the second exhaust duct below the partition member, and an exhaust port is formed in the soundproof case above the partition member to communicate the second exhaust duct with the outside. The exhaust duct structure of a soundproof engine generator is characterized by:
