特徴とする内燃機関のブローバイガス還元装置。 In a blow-by gas return device for an internal combustion engine, the blow-by gas is returned to the intake passage from a pair of cam chambers in which an intake valve train mechanism and an exhaust valve train mechanism are arranged independently. a first oil separator disposed with its lower part communicating with the upper part of the communicating passage; and an upper part of at least one of the cam chambers or a first oil separator of the communicating passage that communicates the cam chambers with each other. A second oil separator whose lower part is connected in communication with the upper part of the part separated from the oil separator mounting part, and the upper part of the first oil separator and the intake passage downstream of the throttle valve are controlled by blow-by gas. a blow-by gas recirculation passage communicating through a valve; and the first
and a gas passage that communicates and connects each upper part of the second oil separator with an intake passage upstream of the throttle valve.
