摘要： Past exhaust emission control systems fail to utilize exhaust gas recirculation during all operating parameters of an engine. The present exhaust gas recirculation system reduces the emissions emitted from an engine during all operating parameters of the engine. The engine includes a cylinder, a rotatable crankshaft and a turbocharger defining a compressor section compressing a flow of intake air to a first preestablished pressure and being driven by a flow of exhaust gas having a first preestablished pressure. The exhaust gas recirculation system is comprised of a portion of the flow of exhaust gas being recirculated to the cylinder and forming a flow of recirculated exhaust gas. The flow of recirculated exhaust gas is cooled. A portion of the flow of intake air is compressed to a second preestablished pressure. The flow of recirculated exhaust gas is compressed to a second preestablished pressure being at least as great as the first preestablished pressure of the intake air. And, a quantity of the flow of recirculated exhaust gas is controlled by a valve having an open position in which intake air flows therethrough and a closed position in which the flow of intake air is blocked.

摘要： A flexible coupling device for sealably connecting together first and second tubular bodies which are subjected to pulsing pressures and to thermal expansion and contraction. The first tubular body includes a first tubular portion having a cylindrical end and a flange and the second tubular body includes a second tubular portion having a planar mounting surface. The flexible coupling device includes a guide ring disposed in telescopic relation with the cylindrical end of the first tubular body, a flexible bellows having first and second attachment ends, a first retaining ring for releasably securing the first attachment end of the flexible bellows to the flange and a second retaining ring for releasably securing the second attachment end and the guide ring to the planar mounting surface of the second tubular portion.
