Abstract (en)
[origin: US2018230874A1] An engine radiator cooling fluid circuit and an exhaust gas intercooler (EGI) radiator cooling fluid circuit are fluidically in parallel with one another. The engine radiator cooling fluid circuit extends from the radiator to an engine associated with a vehicle or a stationary system such as a CHP system. The EGI radiator cooling fluid circuit extends from a radiator to an EGI that cools exhaust gas as it flows through an exhaust conduit that extends from a first catalytic converter to a second catalytic converter. The radiator cooling fluid circuits can share a common radiator coil or each radiator cooling fluid circuit can be associated with a respective radiator coil in the radiator. A gas particulate filter can be coupled to the exhaust conduit or the second catalytic converter. An air-driven exhaust gas ejector (EGE) such as an engine charger compressor injects air into an inlet port in the exhaust conduit.
