<P>PROBLEM TO BE SOLVED: To provide an exhaust gas recirculation type intake device composed in a way that a recirculation port 13 for exhaust gas is open from an exhaust system at a part on the downstream side of an intake passage 10 than a throttle valve 11 and that such recirculation port is opened and closed by a recirculation control valve 15 for reducing deposit attaching on the recirculation port and the recirculation control valve caused by the oil contained in the intake gas. <P>SOLUTION: A section 10a at a position lower than the recirculation port on the intake passage is provided on the upstream side of the intake passage than the throttle valve and an oil reservoir chamber 12 is provided at such the lower section. The oil reservoir chamber and the section on the downstream side of the intake passage than the recirculation port are connected with each other through a communication passage 17. Also a stemming section 18 which is projected towards the center from the inner periphery face of the intake passage is provided on a section between the recirculation port and the throttle valve of the intake passage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
