摘要: Various methods and systems are provided for reducing cylinder-to-cylinder variation in exhaust gas recirculation. In one embodiment, a system 300 comprises a first cylinder group 303 of an engine having a first number of cylinders, a second cylinder group 304 of the engine having a second number of cylinders that is not an integer multiple of the first number of cylinders, and an exhaust system 320 coupled to the first cylinder group 303 and the second cylinder group 304. In at least one mode of operation, the exhaust system has exhaust ports of the first cylinder group fluidly coupled to an intake of the engine and exhaust ports of the second cylinder group fluidly decoupled from the intake.
