ABSTRACT:
An exhaust recirculation system includes a power source including at least one cylinder outputting exhaust gas and a particulate reducing device fluidly connected to at least one exhaust duct of the power source. The particulate reducing device is configured to reduce an amount of particulates in the exhaust gas. The exhaust recirculation system also includes a recirculation compressor configured to receive and compress at least a portion of the exhaust gas. An intake duct of the at least one cylinder of the power source is fluidly connected to the recirculation compressor to receive the compressed reduced-particulate exhaust gas.
