An air intake apparatus for an internal combustion engine, the air intake apparatus includes: an air intake apparatus main body portion introducing air into a cylinder; a port portion provided integrally with a downstream side end portion of the air intake apparatus main body portion and inserted into an air intake port in a cylinder head; an air intake passage formed inside the air intake apparatus main body portion and the port portion, and through which an air-fuel mixture containing air and fuel flows; an injector provided in the air intake apparatus main body portion and introducing the fuel into the air intake passage; and a heater heating the fuel introduced by the injector. The injector is disposed at a position where the fuel is capable of being injected into the heater.

Air intake apparatus for internal combustion engine

A blowby gas treatment device is configured to discharge blowby gas inside an internal combustion engine to an intake passage inside an intake manifold. The blowby gas treatment device includes a blowby gas passage, a flow control valve, a communication hole, and a lid. The blowby gas passage includes an engine gas passage and an intake manifold gas passage. The communication hole is provided in the intake manifold. The communication hole is configured to connect outside of the intake manifold and a part of the intake manifold gas passage on a downstream side of the flow control valve in a gas flow direction. The communication hole opens the intake manifold gas passage to the atmosphere. A lid is configured to open and close the communication hole.

Blowby gas treatment device, intake manifold and internal combustion engine

An intake manifold capable of discharging oil or water in a liquid reservoir in a stable manner includes an introduction section for introducing air to a combustion chamber of an engine, a liquid reservoir provided under the introduction section for retaining a liquid medium, a differential pressure tank including a first chamber, a second chamber, and a differential pressure valve for regulating flow from the second chamber to the first chamber, a return passage for allowing the liquid medium accumulated in the liquid reservoir to return to the first chamber from the liquid reservoir when the pressure in the second chamber is higher than the pressure in the first chamber, and an exhaust passage for discharging the liquid medium having flown into the second chamber from the first chamber to the instruction section when the pressure in the second chamber is lower than the pressure in the first chamber.
