Abstract

An engine system having donor cylinders and non-donor cylinders is disclosed. The engine system may have a first intake manifold configured to distribute air into the non-donor cylinders, and a second intake manifold separate from the first intake manifold and configured to distribute air into the donor cylinders. The engine system may also have a first exhaust manifold configured to discharge exhaust from the non-donor cylinders to the atmosphere, and a second exhaust manifold separate from the first exhaust manifold and configured to recirculate exhaust from the donor cylinders to the first intake manifold. The engine system may further have an orifice configured to regulate a flow rate of air flowing into the second intake manifold, a blower configured to regulate a flow rate of exhaust that is recirculated from the donor cylinders to the first intake manifold, and a controller configured to selectively control at least one of the orifice and the blower in response to a desired exhaust gas recirculation operating condition.
