Title:
【発明の名称】内燃機関のブローバイガス還流装置
Document Type and Number:
Japanese Patent JP2582267
Kind Code:
B2
Abstract:
In a blow-bye gas return device of an internal combustion engine having a blow-bye gas return passage for conducting blow-bye gas from the engine into an integrally combined structure of a fuel injection body and a throttle body, the blow-bye gas return passage has a blow-bye gas discharge orifice which opens toward the upstream side of an air intake passage formed within the injection body around a fuel injector. The discharge orifice is located upstream of the injection port of the injector and on the opposite side of an air flow sensor, whereby the blow-bye gas discharge orifice is free from the injection fuel from the injection port and the air flow sensor is free from oil mist discharged from the blow-bye gas discharge orifice. Further, the blow-bye gas discharge orifice is located at a position where the dynamic pressure is low, whereby the flow resistance is low.
