Output power control / control system for an internal combustion engine

Output power control / control system for an internal combustion engine (10), an electric throttle control apparatus (1, 8, 9, 12) for electrically controlling / regulating a throttle valve (2), the one of the engine (10) to be supplied to intake air controls / regulates, as well as an accelerator (18), wherein the output control / control system includes: a Unsteuerbarkeitsbestimmungsmittel (12) for determining whether the electric throttle control apparatus (1, 8, 9, 12) is in a state or not, in which it is not for controlling the throttle valve (2) in a position; an excitation interrupting means (12) for interrupting the energization of the electric throttle control apparatus (1, 8, 9, 12) when it is determined by the Unsteuerbarkeitsbestimmungsmittel (12), that the electric throttle control apparatus (1, 8, 9, 12) is in the state in which it is not for controlling the throttle valve (2) in a position; a default opening holding means (4) for holding a throttle opening (AP) of the throttle valve (2) on a standard open degree, when it is determined that the electric throttle control apparatus (1, 8, 9, 12) is not for controlling the throttle valve (2) is capable of ; a rotational speed detecting means (15) for detecting a rotational speed (NE) of the engine (10); a load detecting means (16) for detecting the load (PBA) on the machine (10); Load a Basiszundzeitpunktberechnungsmittel (12) for calculating a basic ignition timing (Θmap) according to the from the rotational speed detecting means (15) detected rotational speed (NE) and from the load detecting means (16) detected (PBA) on the machine (10); and an accelerator pedal operation amount detection means (17) for detecting an operation amount of the accelerator pedal (18); marked by a Zundzeitpunktbestimmungsmittel (12) for determining the ignition timing (Θig) of the machine (10) by correcting the basic ignition timing (Θmap) according to the detected operation amount of the accelerator pedal (18) when it is determined that the electric throttle control apparatus (1, 8, 9, 12 ) is in a state in which it is not (for the control of the throttle valve 2) in a position ...
