    摘要： An internal combustion engine includes a combustion air supply; an exhaust manifold; and an induction venturi. The induction venturi includes a combustion air inlet connected and in communication with the combustion air supply, an exhaust gas inlet connected and in communication with the exhaust manifold, and an outlet. A venturi section terminates at a venturi throat and is in communication with the combustion air inlet. An expansion section is positioned between and in communication with the venturi section and the outlet. At least one induction port terminates adjacent the venturi throat and within the expansion section.

    摘要： An internal combustion engine including at least one cylinder head defining a plurality of combustion cylinders. Each combustion cylinder has a displacement volume. An exhaust manifold is fluidly connected to each cylinder for transporting exhaust gas therefrom. An intake manifold provides combustion air to each cylinder. A turbocharger is driven by exhaust gas from the exhaust manifold and provides charged combustion air to the intake manifold. A mixing vessel has at least two inlets, at least one outlet and a mixing chamber. One of the inlets is fluidly connected with the exhaust manifold and an other of the inlets is fluidly connected with the turbocharger. The one inlet and the other inlet are connected with the mixing vessel in a parallel manner. The mixing chamber has a volume which is dependent upon a plurality of the displacement volumes.

    摘要： An outwardly opening valve system for an engine includes an engine having a hollow piston cylinder in fluid communication with a gas passageway via an opening. The engine also has a piston bore that opens to the hollow piston cylinder. A portion of the opening includes an outward valve seat positioned adjacent the gas passageway. An outward valve member with a valve face is positioned substantially in the gas passageway. The valve member is moveable between a closed position in which the valve face is against the valve seat closing the opening and an open position in which the valve face is away from the valve seat. An intensifier piston is positioned to reciprocate in the piston bore and has one end contacting gas within the hollow piston cylinder. Finally, a coupling linkage interconnects the intensifier piston to the outward valve member so that the valve member is held closed during combustion by exploiting combustion pressure within the hollow piston cylinder.

    摘要： An internal combustion engine, particularly suitable for use in a work machine, is provided with an exhaust manifold, a turbocharger, and a bypass venturi assembly. The turbocharger includes a turbine and a compressor, with the turbine having a variable geometry inlet coupled with the exhaust manifold, and the compressor having an outlet. The bypass venturi assembly includes a housing having an outlet, a combustion air inlet and an exhaust gas inlet. The combustion air inlet is coupled with the compressor outlet. The exhaust gas inlet is coupled with the exhaust manifold. A center piece is positioned within the housing and is in communication with the combustion air inlet. The center piece defines a combustion air bypass section therein. A combustion air bypass valve is positioned in association with the combustion air bypass section. The exhaust gas valve is positioned in association with the exhaust gas inlet. The variable geometry inlet of the turbine allows the pressure ratio of the compressed combustion air to be varied, thereby improving the mixing efficiency of the exhaust gas with the combustion air.
