Abstract

The invention provides a gas leakage processing device which can prevent freezing of moisture in an air inlet channel and improves rigidity of a bending portion of the air inlet channel. The gas leakage processing device (1) comprises a breather pipe (7) which makes leaked gas of a motor (2) flow back to an air inlet pipe (3). The gas leakage processing device (1) comprises a cavity (8). The cavity (8) is arranged on the inner side of the bending portion (3A) of the air inlet pipe (3) in a protruded manner. The cavity (8) is provided with a guiding-in hole (81) used to lead one end of the breather pipe (7) in.

Description

technical field [0001] The invention relates to a gas leakage processing device. Background technique [0002] Conventionally, there is known a blow-by gas treatment device that recirculates blow-by gas of an internal combustion engine into an intake passage. The blow-by gas treatment device includes, for example, a breather tube that connects a breather chamber formed by the internal space in the cylinder head cover and communicated with the crank chamber in a breathable manner to the intake passage. This breather pipe normally introduces fresh air into the breather chamber, but at low temperatures, the moisture contained in the blow-by air flowing through the PCV (Positive Crankcase Ventilation: Positive Crankcase Ventilation) pipe freezes and closes the PCV pipe , the blow-by gas flows back and flows in, thereby causing the blow-by gas to flow back into the intake passage. [0003] However, when the breather pipe is frozen and closed in addition to the PCV pipe, the int...
