1. An intake manifold, comprising:
a first inlet structured to receive pressurized intake air from a turbocharger;
a second inlet structured to receive exhaust gas recirculation gas from an exhaust gas recirculation system;
a third inlet structured to receive fuel from a fuel line;
a plurality of outlets structured to be fluidly coupled to an engine; and
an intake manifold passage extending between each of the first, second, and third inlets, and the plurality of outlets, the intake manifold passage 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.
