装置。In a blowby gas return device that returns blowby gas from a crank chamber of a turbocharged engine to an engine intake air filter via a blowby gas return tube, the blowby gas is returned to the air filter via a main chamber housing a filter element and a throttle hole. Forms a communicating subchamber,
The blow-by gas return tube is made as long as possible, and connected to the sub-chamber of the air filter through a throttle hole, and is exposed to the atmosphere through a check valve and a filter opened on the sub-chamber side of the sub-chamber. An atmospheric air intake port that opens is provided, and when the internal pressure in the pre-chamber drops below a predetermined pressure due to an increase in suction negative pressure of the turbocharger, a check valve opens to suck in atmospheric air, thereby preventing the suction of blow-by gas more than necessary. A blow-by gas reduction device for a turbocharged engine, characterized in that the blow-by gas is restricted.
