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.
