摘要： An exhaust gas recirculation (EGR) system for a turbo-charged internal combustion engine is provided. The EGR system includes a recirculation conduit for recirculating a volume of exhaust gas from the exhaust manifold to the intake manifold; a cooling air conduit for transporting a flow of cooling air; and a gas-to-air heat exchanger disposed in operative association with the recirculation conduit and the cooling air conduit and adapted for cooling the volume of recirculated exhaust gas in the recirculation conduit. The cooling air passing through the gas-to air heat exchanger can be diverted from the pressurized intake air, cooled (ATAAC) air, or even fresh ambient air obtained from a source external to said engine and which optionally may be forcibly directed through the heat exchanger via a blower. The disclosed embodiments disclose EGR systems where the exhaust gases are driven from the exhaust manifold to the intake manifold through different techniques including peak clipping EGR systems, venturi based EGR systems, pumped EGR systems or piston pumped EGR systems.

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 method and system for the control of the fuel injection timing in an internal combustion engine using a low cetane quality fuel such as an aqueous fuel emulsion is provided. The disclosed system includes a compression ignition engine adapted to receive a prescribed supply of an aqueous fuel emulsion. The prescribed supply of fuel is preferably determined by an fuel system control unit as a function of one or more engine operating parameters. The disclosed system also includes an exhaust sensor located proximate the engine exhaust so as to detect the presence and level of selected exhaust products, such as carbon monoxide, in the engine exhaust. The level of carbon monoxide or other such exhaust product, as measured by the sensor, is input to the engine control unit where it is processed together with various other engine operating parameters to produce a prescribed fuel injection timing signal which operatively controls the fuel injection timing.
