Abstract
According to one implementation, a centrifugal oil mist separator includes a duct, a fan and a power transmission mechanism. The duct forms a flow path of a first exhaust gas discharged from an engine. The first exhaust gas includes oil mist. The fan is disposed inside the duct. The power transmission mechanism rotates the fan using energy of a second exhaust gas discharged from the engine. The second exhaust gas includes no oil mist.
