发明名称 Internal combustion engine
摘要 An internal combustion engine has at least one cylinder group including a plurality of cylinders and at least one exhaust turbocharger, each cylinder including a plurality of outlet valves for exhaust gas, each outlet valve being assigned an outlet duct which opens into an exhaust manifold and via which the respective exhaust gas, after flowing through the respective outlet valve and outlet duct, can be guided in the direction of an exhaust turbocharger, and first outlet ducts of the cylinders being contoured in the manner of nozzles, and second outlet ducts of the cylinders being contoured in the manner of diffusers.

主权项 1. An internal combustion engine comprising: a plurality of cylinders in at least one cylinder group; and at least one exhaust turbocharger receiving exhaust gas from the internal combustion engine; wherein each of the plurality of said cylinders in the at least one cylinder group comprise a first outlet valve and a second outlet valve for exhaust gas to be discharged; wherein the first outlet valve is assigned a first outlet duct extending outside of one of the cylinders of the plurality of said cylinders that receives exhaust gas from the first outlet valve and opens into a first exhaust pipe which opens into a first common exhaust manifold and is guided in a direction toward to a turbine of the at least one exhaust turbocharger; wherein the first outlet duct of said each of the plurality of the cylinders in the at least one cylinder group is contoured in the manner of a nozzle; wherein the second outlet valve is assigned a second outlet duct extending outside of one of the cylinders of the plurality of said cylinders that receives exhaust gas from the second outlet valve and opens into a second exhaust pipe which opens into a second common exhaust manifold and is guided in a direction toward to the turbine of the at least one exhaust turbocharger; and wherein the second outlet duct of said each of the plurality of the cylinders in the at least one cylinder group is contoured in the manner of a diffuser.
