1. A power-generating system comprising:
- a. an internal combustion engine;
b. an electric generator that is driven by the internal combustion engine;
c. a mechanical control unit that is configured to control a RPM of the internal combustion engine;
d. a RPM-determining unit that is configured to determine the RPM of the internal combustion engine; and
e. an electronic control unit that is coupled to the RPM-determining unit and that is configured to control the RPM of the internal combustion engine, wherein the electronic control unit only controls the RPM of the internal combustion engine, thus overriding operation of the mechanical control unit, when the RPM-determining unit determines that the internal combustion engine'"'"'s RPM outside of a prescribed operating range.

Abstract
The invention relates to a generating unit driven by a combustion engine. Control of the engine speed is carried out in a known manner via a mechanical control device which controls a throttle valve in the carburetor system of the engine. In case of a failure of the mechanical control device and, consequently, in case of a change in the engine speed outside a predetermined range, an electronic control system takes over to activate a firing element of the engine and control the engine speed, independently from the mechanical control system, in such a way that the engine speed is maintained within the predetermined range.

8. A power-generating system comprising:
-
a. an internal combustion engine;
b. an electric generator that is driven by the internal combustion engine to generate electric power;
c. a mechanical control unit that is configured to control a rotational velocity of the internal combustion engine;
d. a rotational velocity sensor that is configured to determine the rotational velocity of the internal combustion engine; and
e. an electronic control unit that is coupled to the rotational velocity sensor and to the internal combustion engine, wherein the electronic control unit is operable, when the internal combustion engines rotational velocity as detected by the rotational velocity sensor is outside of a prescribed operating range, to override operation of the mechanical control unit and control the rotational velocity of the internal combustion engine. - View Dependent Claims (9, 10, 11, 12, 13)
