Abstract:
1. An internal combustion engine comprising: a turbocharger configured to receive an exhaust gas flow from the internal combustion engine; an oxidation catalyst close coupled to the turbocharger to receive the exhaust gas flow from the turbocharger; a conduit coupled to the oxidation catalyst to receive the exhaust gas flow from the oxidation catalyst and an emission fluid flow from an injector; a mixer coupled to the conduit to receive the exhaust gas flow and the emission fluid flow from the conduit and to form a mixed exhaust gas and emission fluid flow; a particulate filter and catalytic reduction assembly close coupled to the mixer to receive the mixed exhaust gas and emission fluid flow from the mixer to form a treated exhaust gas flow; and an exhaust gas recirculation system coupled to the particulate filter and catalytic reduction assembly to receive a portion of the treated exhaust gas flow and recirculate the portion of the exhaust gas flow to be mixed with a fresh air flow for the internal combustion engine, wherein the oxidation catalyst, conduit, mixer, particulate filter and catalytic reduction assembly and exhaust gas recirculation system are each located in an engine compartment.
