Abstract

An engine system includes a first cylinder group, a second cylinder group, an inlet manifold coupled to the first cylinder group and the second cylinder group, an inlet passage coupled to the inlet manifold to provide inlet air to the inlet manifold, a first exhaust manifold coupled to the first cylinder group, a second exhaust manifold coupled to the second cylinder group, and a mixer pipe positioned within the second exhaust manifold and/or the intake passage to mix exhaust gas recirculation (EGR) gases exhausted by the second cylinder group that are delivered through the second exhaust manifold with inlet air. The mixer pipe forms an inlet end that is coupled to the second exhaust manifold and an outlet end that is located upstream of the cylinders in the first cylinder group and the cylinders in the second cylinder group.
