Abstract
In an air-cooled type cooling system for an engine working machine assembly in which a working machine such as a generator, a compressor and the like is adapted to be driven by an internal combustion engine, there are provided an air-cooled engine, a working machine and an exhaust muffler in a machine area as well as a centrifugal cooling fan in a fan room within a casing. An exhaust air outlet passage and an exhaust air conduction passage are provided in such a manner as to come out in parallel from the periphery of the fan area. Part of the cooling air sucked into the fan area after cooling the engine and the working machine in the machine area is adapted to be discharged directly outside the casing through the exhaust air outlet passage, and the remaining part thereof is adapted to be discharged outside the casing through the exhaust air conduction passage after cooling the exhaust muffler.
