摘要：A piston-pumped EGR system for an internal combustion engine includes firstand second stationary regenerators. Alternating flow through the first and second
stationary regenerators is controlled by a regenerator directional flow control valve influid communication with at least one check valve disposed between the regeneratordirectional flow control valve and an exhaust manifold of the engine. Flow through thestationary recuperators is controlled so that exhaust gas and cooling bleed flow arealternatingly directed through the stationary recuperators whereby heat is removedfrom the recirculated exhaust gas prior to reintroduction into an intake manifold and oneof the stationary regenerators is cooled by bleed air, which is subsequently dischargedinto the exhaust manifold of the engine.
