Abstract: An engine system for a machine is disclosed. The engine system may have an intake manifold configured to direct air into a donor cylinder and a non-donor cylinder of an engine. The engine system may also have a first exhaust manifold configured to direct exhaust from the non-donor cylinder to the atmosphere. The engine system may also have a second exhaust manifold configured to receive exhaust from the donor cylinder. The engine system may further have a control valve configured to selectively direct a first amount of exhaust from the second exhaust manifold to the intake manifold. In addition, the engine system may have an orifice configured to allow a second amount of exhaust to flow from the second exhaust manifold to the first exhaust manifold.

Abstract: An engine system is disclosed for use with an engine having at least a first cylinder and a second cylinder. The engine system may have a first exhaust manifold fluidly connected to the first cylinder, a second exhaust manifold fluidly connected to the second cylinder, and a recirculation passage extending from the first exhaust manifold to at least one of the first and second cylinders. The engine system may also have a restricted orifice connecting the first exhaust manifold to the second exhaust manifold, a pressure relief passage extending from the first exhaust manifold, and a valve disposed within the pressure relief passage and movable to selectively reduce a back pressure of the first exhaust manifold.
