Title:
EGR DEVICE AND ENGINE DEVICE WITH SAME
Document Type and Number:
WIPO Patent Application WO/2010/090069
Kind Code:
A1
Abstract:
An EGR device (91) for recirculating, as an EGR gas, a part of the exhaust gas, which is discharged from an exhaust manifold (71), to an intake manifold (73) is adapted so that the EGR device (91) can be used in common among different models of various working vehicles. In the EGR device (91), the intake manifold (73) and an intake throttle member (146) for introducing fresh air are connected through a relay conduit (145). The exit side of a recirculation conduit (148) extending from the exhaust manifold (71) is connected to the relay conduit (145). The relay conduit (145) is provided so that the direction thereof can be changed in multiple directions about the inlet section (73a) of the intake manifold (73). Thus, the direction of an intake system on the upstream side of the intake manifold (73) can be selected and changed without changing the structure of the relay conduit (145).
