Abstract
An internal combustion engine with at least one control element for variation of the flow cross-section of a charge exchange passage, which control element is automatically adjustable in accordance with the engine mode by means of an actuating member and a connecting element. In order to permit automatic adjustment of the control element in dependence of engine speed and load in a simple manner, the internal combustion engine be flexibly supported in a frame, and that the actuating member of the control element be supported via the connecting element on at least one pivot fixed in the frame, such that the control element can adjust itself with increasing torque, due to the relative movement between engine and frame resulting from the torque of the combustion engine, thereby increasing the flow cross-section of the charge exchange passage while varying the beginning of the charge changing process.
