Abstract
Described is an engine with a camshaft having a single cam profile, a gas intake manifold, and an exhaust gas rebreather system for receiving an exhaust gas from the engine. The exhaust gas rebreather system includes a main exhaust gas outlet configured to receive the exhaust gas. An exhaust gas rebreather line of the exhaust gas rebreather system returns a portion of the exhaust gas in the main exhaust gas outlet to the gas intake manifold. A variable nozzle turbocharger having one or more variable nozzle vanes is in fluid connection with the main exhaust gas outlet. The exhaust rebreather system further includes an exhaust gas recirculation valve and a back pressure valve. The exhaust gas recirculation valve is disposed in the exhaust gas rebreather line and in fluid connection with the main exhaust gas outlet, and the back pressure valve downstream of the variable nozzle turbocharger.
