    Abstract: An engine output control system includes an engine ECU having a fundamental ignition timing map, a fundamental fuel injection quantity map, a target throttle angle determination unit for determining a target throttle angle of an exhaust control valve, an exhaust control valve diagnosis unit for diagnosing operation of the exhaust control valve, an ignition timing map to be used during an abnormality for determining fundamental ignition timing when the exhaust control valve operates abnormally, and an abnormal fuel injection thinning-out table for determining a reduced rate of fuel injection when the exhaust control valve has been diagnosed as abnormal. The exhaust control valve driving unit supplies a driving current to an actuator in such a manner that the target throttle angle notified by the engine ECU coincides with actual valve throttle angle. The system is capable of obtaining sufficient traveling performance even when an exhaust control valve has is operating abnormally.

    Abstract: The invention relates to an internal combustion engine with at least one control element (6, 14) for variation of the flow cross-section of a charge exchange passage, which control element (6, 14) is automatically adjustable in accordance with the engine mode by means of an actuating member (8) and a connecting element (9). In order to permit automatic adjustment of the control element (6, 14) in dependence of engine speed and load in a simple manner, it is proposed that the internal combustion engine be flexibly supported in a frame (1), and that the actuating member (8) of the control element (6, 14) be supported via the connecting element (9) on at least one pivot (10) fixed in the frame (1), such that the control element (6, 14) can adjust itself with increasing torque, due to the relative movement between engine (2) and frame (1) 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.
