摘要： PROBLEM TO BE SOLVED: To enhance a stratifying degree of intake air in a combustion chamber while securing fresh air quantity.SOLUTION: An intake and exhaust device has an intake pipe 12T connected to a tumble port supplying a tumble flow to a combustion chamber and supplying intake air to the combustion chamber. The intake pipe 12T has an EGR channel 18 to which EGR gas are supplied, a fresh air channel 19 to which the intake air mainly containing fresh air is supplied, and a merging part 20 to which the EGR channel 18 is connected and the fresh air channel 19 is connected, a switching valve 24 alternatively opening and closing an EGR opening 18a and a fresh air opening 19a is arranged in the merging part 20. By this constitution, EGR gas and fresh air can be introduced from the intake pipe 12T connected to one port by the switching valve 24 by a time lag. Consequently, a fresh air quantity can be sufficiently secured from the fresh air channel 19 despite enhancing a concentration of EGR gas in the EGR channel 18 for raising stratifying degree different from a conventional embodiment using one of two ports exclusively for EGR gas.
摘要翻译：要解决的问题：在确保新鲜空气量的同时提高燃烧室内的进气分层度。解决方案：进气和排气装置具有连接到翻转端口的进气管12T，其向燃烧室供应翻转流并供应进入燃烧室的空气。进气管12T具有供给EGR气体的EGR通道18，供给主要包含新鲜空气的吸入空气的新鲜空气通路19和与EGR通道18连接的合流部20，通道19连接，在合流部20中配置有交替地开闭EGR开口18a和新鲜空气开口19a的切换阀24.通过这种结构，EGR气体和新鲜空气可以从连接到一个端口由切换阀24延迟。因此，尽管使用专门用于EGR气体的两个端口之一来增加EGR通道18中的EGR气体的浓度以增加与常规实施例不同的分层度，但可以从新鲜空气通道19充分确保新鲜空气量。

摘要： PROBLEM TO BE SOLVED: To provide a vehicle intake manifold capable of causing an engine to suck water or oil collected in a surge tank, even if a lower edge of a connection between the surge tank and an intake branch is above the lower part of the surge tank.
SOLUTION: The intake manifold 1 is provided with a communicating pipe 6 that communicates a lower portion of the surge tank 4 with an airflow separation section A (intake branch 5 side) of a bent section 34 while bypassing the intake downstream side of the surge tank 4. A differential pressure is produced between both ends of the communicating pipe 6 by airflow separation or the like caused by the flow of intake, and a fluid suction force from the surge tank 4 side to the intake branch 5 side is created inside the communicating pipe 6. In this way, water or oil in the lower portion of the surge tank 4 can be sucked up into the intake branch 5 via the communicating pipe 6 and be sucked into the engine 3.

摘要： PROBLEM TO BE SOLVED: To provide an air intake apparatus for a vehicle capable of introducing water and oil gathered in a lower part of a surge tank 31 into a cylinder of an engine.SOLUTION: When an operation state of the engine is in idling, acceleration operation and high speed operation, pushing-in force of turning to the lower side of the surge tank 31 is generated by "differential pressure between an intake branch 32 nearer to the cylinder of the engine and the surge tank 31" and "differential pressure generated by a difference in an intake flow speed between the inside of the surge tank 31 and the inside of the intake branch 32", and the water and the oil gathered in the lower part of the surge tank 31 are pushed in the intake branch 32 side of a communicating tube 11 via a discharge pipe 12. When the operation state of the engine is in deceleration operation, an opening-closing valve 13 of the communicating tube 11 is opened, and thereby, the water and the oil existing in the communicating tube 11 can be forcibly fed to the intake branch 32 by using the differential pressure generated between the intake flow upstream side and the intake flow downstream side of a throttle valve 2.

摘要： PROBLEM TO BE SOLVED: To prevent damage to a housing 3 when press-fitting a fitting ring of a resin seal 5, in a valve device preventing leakage around a rotary shaft 9 by the resin seal 5 which is made of fluorine resin as a raw material.SOLUTION: A resin seal 5 which is made of fluorine resin as a raw material is pinched by a metal bearing 19 and a step 29 of a housing 3 in an axial direction, and arranged on the upstream side of all functional components 4 around the shaft with regard to a leakage flow of exhaust gas around a rotary shaft 9. Thereby, the resin seal 5 functions as a shaft seal by coming into sliding contact with an outer peripheral surface of the rotary shaft 9. Also, even without using a fitting ring which was conventionally needed for holding the resin seal 5, the resin seal 5 can be held and brought into sliding contact with the rotary shaft 9. Therefore, press-fitting work of the fitting ring can be eliminated, and damage to the housing 3 can be prevented.
