AIR INTAKE DEVICE FOR ENGINE

An air intake passage (bypass passage that bypasses a supercharger) 25 for an engine is connected to an EGR passage 6. The EGR passage comprises an enlarged portion 95, in which the cross-sectional area of the passage is enlarged, and which reduces the flow rate of an EGR gas before a connection por...

Beschreibung
Zusammenfassung:	An air intake passage (bypass passage that bypasses a supercharger) 25 for an engine is connected to an EGR passage 6. The EGR passage comprises an enlarged portion 95, in which the cross-sectional area of the passage is enlarged, and which reduces the flow rate of an EGR gas before a connection port 69 to the intake passage 25 so as to suppress the EGR gas flowing into the intake passage 25 fromhaving an uneven flow distribution in the connection port 69. 使EGR通路(6)与发动机的进气通路(绕过增压器的旁通通路)(25)连接。所述EGR通路在与进气通路(25)之间的连接口(69)的近前具有通路截面积扩大了的扩大部(95)，所述扩大部(95)使EGR气体的流速降低，以抑制流入进气通路(25)的EGR气体在连接口(69)处产生偏流。
