Abstract
The working fluid circuit of the present invention includes an exhaust gas passage through which exhaust gas under pressure flows from the internal combustion engine, a charge air passage, and a turbocharger. An exhaust gas recirculation passage extends between the exhaust gas passage and the charge air passage, but bypasses the turbocharger and provides a path for recirculating a predetermined amount of exhaust gas into the charge air passage in such a way that the exhaust gas and the charge air are mixed together. An intake passage provides intake air to the internal combustion engine. A single charge air cooler is operatively interconnected to and provides fluid communication between the charge air passage and the intake passage and acts to cool the mixed charge air and the recirculated exhaust gas prior to induction into the internal combustion engine through the intake passage.
