    摘要: An engine exhaust silencer arrangement with a variable geometry, which is controlled by control elements in dependence of engine data. The increased exhaust noise occurring during engine operation under differing engine stroke modes is suppressed by the different geometry of the silencer arrangement.

    摘要: In an internal combustion engine with a crankshaft and an exhaust gas duct including an exhaust gas power turbine which is coupled to the crankshaft via a variable transmission, a control unit is provided for controlling the transmission ratio of the variable transmission such that the speed of the turbine is adapted to the flow speed of the exhaust gas through the turbine in such a way that the turbine is always operated in an optimal efficiency range.
