Abstract
Official abstract text for this publication.
An exhaust gas recirculation system according to the present invention includes an EGR passage for introducing a part of exhaust gas emitted from an engine to an intake passage, the EGR passage communicating at one end thereof with the intake passage whereas at the other end thereof with an exhaust passage, an EGR control valve for controlling the flow rate of the exhaust gas flowing therein, the EGR control valve being disposed at one end of the EGR passage, an on-off valve for opening or closing the EGR passage, the on-off valve being disposed at the other end of the EGR passage, and a heat exchanger for cooling the exhaust gas introduced to the EGR passage, the heat exchanger) being disposed nearer the other end of the EGR passage than the on-off valve.
First claim
Opening claim text (preview).
The invention claimed is: 1. An exhaust gas recirculation system comprising: an EGR passage for introducing a part of exhaust gas to be emitted from an internal combustion engine to an intake passage, the EGR passage communicating at one end thereof with the intake passage whereas at the other end thereof with an exhaust passage; an EGR control valve for controlling the flow rate of the exhaust gas flowing in the EGR passage, the EGR control valve being disposed at one end of th…
