FIXED POSITIVE DISPLACEMENT EGR SYSTEM

摘要

A fixed positive displacement exhaust gas recirculation (EGR) system includes an intake manifold in fluid communication with a fresh intake air source, an exhaust manifold, and an engine having at least one EGR cylinder and at least one non-EGR cylinder. The at least one EGR cylinder is in fixed fluid communication with the intake manifold such that substantially all of the exhaust gas flows from the at least one EGR cylinder to the intake manifold, and the at least one non-EGR cylinder is in communication with the exhaust manifold such that exhaust gas flows from the at least one non-EGR cylinder into the exhaust manifold.

1. A fixed positive displacement exhaust gas recirculation (EGR) system, comprising:
(a) an intake manifold in fluid communication with a fresh intake air source; (b) an exhaust manifold; and (c) an engine having at least one EGR cylinder and at least one non-EGR cylinder, wherein the at least one EGR cylinder is in fixed fluid communication with the intake manifold such that substantially all the exhaust gas from the at least one EGR cylinder flows to the intake manifold, and wherein the at least one non-EGR cylinder is in fluid communication with the exhaust manifold such that the exhaust gas flows from the at least one non-EGR cylinder into the exhaust manifold.
