Abstract: An intake manifold is provided. A first inlet is structured to receive pressurized intake air from a turbocharger. A second inlet is structured to receive exhaust gas recirculation gas from an exhaust gas recirculation system. A third inlet is structured to receive fuel from a fuel line. A plurality of outlets are structured to be fluidly coupled to an engine. An intake manifold passage extends between each of the first, second, and third inlets, and the plurality of outlets. The intake manifold passage is shaped so as to cause at least two reversals in flow direction of each of the intake air, the exhaust gas recirculation gas, and the fuel through the intake manifold passage so as to improve mixing of each of the intake air, the exhaust gas recirculation gas, and the fuel.
