FIELD: anti-icing devices.
SUBSTANCE: present invention relates to an anti-icing device for outlet branch pipe PCV (forced vent crankcase) of intake manifold. Anti-icing device of outlet branch pipe PCV includes first guide device (51) and second guide device (52), which are formed near PCV outlet branch pipe (42) inside inlet tube (20) of inlet manifold (1) and are intended to prevent direct contact between external air and PCV-gases, thereby preventing condensation and freezing of PCV-gases. First guiding device and the second guiding device also serve to improve the capabilities of the inlet header as to distribution of flow due to improvement of fluidity of external air.
EFFECT: reduced icing of PCV discharge branch pipe.
