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.
