Title: Egr device for engine with supercharger
Inventor: MAEKAWA MASAHIRO
IPC: F02D9/04
Filed: 2000-07-18
Abstract: PROBLEM TO BE SOLVED: To provide an ERG device for an engine with a supercharger capable of reducing a manufacturing cost by simplifying a structure, and certainly recirculating the EGR without a lowering of engine efficiency due to increasing of exhaust resistance. SOLUTION: A second exhaust manifold 14 corresponding to a second exhaust valve 11b is provided separately from a first exhaust manifold 13 corresponding to a first exhaust valve 11a, and a control valve 15 is provided on an assembling portion 14a of the second exhaust manifold 14. An upper stream side of the control valve 15 and an intake passage 6 are connected by an EGR passage 17. When exhaust side pressure exceeds intake side pressure and EGR is impossible, the control valve 15 is closed to throttle exhaust gas, and opening/closing timing of the second exhaust valve 11b is advanced, thereby increasing exhaust pressure by blowing down.  The exhaust pressure is increased by the single control valve 15, so that a manufacturing cost is reduced, and the exhaust gas with a sufficiently decelerated flow speed is throttled by the control valve 15, so that exhaust resistance is hardly increased.
