Abstract

An engine generator apparatus controls the air-fuel ratio in response to the stable output of an oxygen sensor. When a system protectordetects a disorder in a power network, it outputs failure signal. A connection relayis opened in response to the failure signal to release connection of a generator to the power network to release load. When the failure signal is not detected, a load determination sectionurges a proportional valve controllerand the controllerdrives a valvecorresponding to the oxygen density to perform a control of the air-fuel ratio. The load determination sectiondetermines that the load is released by the failure signal to send a notification of no load to the controller. The controllerstops the control of the air-fuel ratio based on the oxygen density in response to this notification.
