Claims

[Scope of utility model registration request]

In a soundproof engine working machine in which an engine and a working machine driven by the engine are arranged side by side in the direction of the rotation axis and housed in a soundproof case, the bottom of the soundproof case is ventilated at both ends in the direction of the rotation axis. The ventilation space is divided into an engine side and a work machine side, and the work machine is provided with a fan for cooling the work machine, and the engine is provided with a fan for cooling the engine. A fan cover covering a fan for cooling the work equipment is connected to a duct that covers the cylinder part of the engine and the exhaust muffler and opens to the outside of the soundproof case at the end thereof, and the duct is connected to the cooling exhaust air by the fan for cooling the work equipment. a main air intake port into the soundproof case is formed on the work machine side at the bottom of the soundproof case so that the winds merge;
Furthermore, the fan cover is communicated with an oil pan cooling air passage provided along an oil pan portion of the engine, and the oil pan cooling air passage is opened to a ventilation space on the engine side at the bottom of the soundproof case. Features: Soundproof engine working machine.
