Abstract
An internal combustion engine, particularly suitable for use in a work machine, is provided with a combustion air supply and an exhaust manifold. A bypass venturi assembly includes a housing having an outlet, a combustion air inlet and an exhaust gas inlet. 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. An exhaust gas valve is positioned in association with the exhaust gas inlet. A single shaft is coupled with and carries each of the combustion air bypass valve and the exhaust gas valve.
