摘要： A first aspect of the present disclosure includes a power source for use with selective catalytic reduction systems for exhaust-gas purification. The power source may comprise a first cylinder group with a first air-intake passage and a first exhaust passage, and a second cylinder group with a second air-intake passage and a second exhaust passage. The power source may further include a first forced-induction system in fluid communication with the first air-intake passage, and a second forced-induction system in fluid communication with the second air-intake passage. A catalyst may be disposed downstream of the fuel-supply device to convert at least a portion of the exhaust stream in the first exhaust passage into ammonia.

摘要： A method of directing flow of exhaust gas includes directing a first portion of the flow through a first flow path and directing a second portion of the flow through a second flow path. A temperature of at least a portion of the flow in the first flow path is increased, and the flow in the first flow path is sent through a filter. The first and second portions of the flow downstream of the filter to are combined form a combined flow. The combined flow is maintained within a predetermined range of temperatures, and the combined flow is directed to a catalyst.

摘要： 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.

摘要： A power source is provided for use with selective catalytic reduction systems for exhaust-gas purification. The power source has a first cylinder group fluidly connected to a first air-intake passage and a first exhaust passage, wherein the first air-intake passage is configured to provide air at a first set of characteristics. The power source also has a second cylinder group fluidly connected to a second air-intake passage and a second exhaust passage, wherein the second air-intake passage is configured to provide air at a second set of characteristics different from the first set of characteristics. An ammonia-producing catalyst may be disposed within the first exhaust passage and configured to convert at least a portion of a fluid in the first exhaust passage into ammonia. Further, a merged exhaust passage may be configured to connect the first exhaust passage and the second exhaust passage downstream of the ammonia-producing catalyst to facilitate a reaction between ammonia and NOx to at least partially remove NOx from the merged exhaust passage.
