Abstract: An internal combustion engine has a plurality of cylinders, and each cylinder has at least one first and one second exhaust port with associated respective first and second exhaust valves. At least one first and one second exhaust manifold are flow-connected to the respective first and second exhaust ports. A turbo unit for supercharging the charge air delivered to the cylinders comprises at least one first and one second exhaust gas turbine respectively flow connected to the first and the second exhaust manifolds. An exhaust gas chamber flow-connects the first and the second exhaust manifolds upstream of the exhaust gas turbines. The first and second exhaust valves can be deactivated/activated during operation. A throttle valve in the exhaust gas chamber may assume a closed position in order to separate the first and the second exhaust manifolds. A method of operating includes opening and closing different valves at different engine speeds.

Abstract: A multicylinder internal combustion engine with an exhaust-driven turbocompressor and with a divided exhaust gas flow has at least two exhaust valves (2,3) and one intake valve per cylinder. A first exhaust valve (2) is connected to a first exhaust manifold which leads to the turbine of the compressor, while a second exhaust valve (3) is connected to a second exhaust manifold which opens downstream of the turbine. The charging pressure in the engine can be regulated by virtue of the opening periods of the exhaust valves (2,3) being varied in relation to one another in order to adapt the flow through the exhaust turbine to a value which provides the desired charging pressure in the engine. By opening the second exhaust valve (3) increasingly earlier, an increasingly lower charging pressure can be achieved.

Abstract: A multicylinder internal combustion engine with an exhaust-driven turbocompressor and with a divided exhaust flow has at least two exhaust valves and one intake valve per cylinder. A first exhaust valve is connected to a first exhaust manifold which leads to the turbine of the compressor, while a second exhaust valve is connected to a second exhaust manifold which opens downstream of the turbine. In the top dead center position of the piston, the second exhaust valve and the intake valve are open at the same time for a period. The synchronization between these valves is such that the length of the period during which they are open together increases with the engine speed when the engine is driven at high load. In this way, the possibilities are improved of the engine providing good torque over a wide engine speed range.
