Abstract
A method and device is provided for regulating the air-fuel mixture provided to an engine of a stand-by electrical generator during the exercise thereof. The engine is exercised at a predetermined speed less than the normal operating speed of the engine and each cylinder receives an air-fuel mixture having an air component and a fuel component. To exercise the engine, the air component and the fuel component in the air-fuel mixture provided to the engine is reduced. In addition, the volume of the air-fuel mixture provided to each cylinder of the engine is balanced.
