Abstract:
1. An oil collecting structure of a blow-by gas recirculation system, comprising: an oil separator that separates oil mist from a blow-by gas, and feeds the blow-by gas from which the oil mist is separated and removed to an intake system of an internal combustion engine while feeding the oil separated from the blow-by gas to an oil reservoir of the engine; a separated-oil collection passage through which the oil separated from the blow-by gas by the oil separator is fed toward the oil reservoir, said separated-oil collection passage being formed in a main body of the engine and located adjacent to an oil return passage through which an oil used for lubricating the interior of the main body of the engine flows downward; and a heat exchanging portion in which heat of the oil flowing in the oil return passage is imparted to the oil flowing in the separated-oil collection passage.
