  • Patent number: 10890088
    Abstract: An intake manifold 10 includes: a surge tank 11 that is connected on an upstream side thereof to a throttle valve 13; multiple branch pipes 12 that are arranged side by side in a longitudinal direction of the surge tank 11 and respectively connected to cylinders; and a PCV chamber 15 that is provided upstream of a central part in the longitudinal direction of the surge tank 11. The intake manifold includes: a blowby gas introduction port 16g that is designed to introduce blowby gas into the PCV chamber 15; and a blowby gas exhaust port 16f that is designed to discharge the blowby gas from the PCV chamber 15 into the surge tank 11, and the blowby gas exhaust port 16f is located at a position higher than the blowby gas introduction port 16g.

  • Patent number: 10830193
    Abstract: An intake manifold 10 includes: a blowby gas introduction port 16g that is configured to introduce blowby gas into a PCV chamber 15; a blowby gas exhaust port 16f that is configured to discharge the blowby gas from the PCV chamber 15 into a surge tank 11; and a drain hole 17c that is configured to discharge water contained in the blowby gas, from the PCV chamber 15 into the surge tank 11. A bottom wall 17d of the surge tank 11 includes protruding parts 17e, 17f that protrude upward, the blowby gas exhaust port 16f is located upstream of the most upstream side protruding part 17e located on the most upstream side, and the drain hole 17c is located downstream of the most upstream side protruding part.

  • Patent number: 7661405
    Abstract: Provided is a throttle valve device for an internal combustion engine which is favorably protected from icing, and enables a favorable control of the intake flow rate by avoiding an abrupt increase in the flow rate particularly in a small opening angle range. An upstream recess (21) and a downstream recess (22) are formed in a lower part of the throttle bore (11) of the throttle valve device. Moisture that may deposit on the inner wall of the throttle bore is allowed to be drained to the recesses. A cross sectional area of one of the recesses over which the lower edge of the throttle valve member sweeps as the throttle valve member (30) opens from the fully closed position is smaller than that of the other recess so that an abrupt change in the intake flow rate can be avoided in a small opening angle region.
