ABSTRACT:
An engine generator apparatus controls the air-fuel ratio in response to the stable output of an oxygen sensor. When a system protector138detects a disorder in a power network, it outputs failure signal. A connection relay135is 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 section41urges a proportional valve controller40and the controller40drives a valve35corresponding to the oxygen density to perform a control of the air-fuel ratio. The load determination section41determines that the load is released by the failure signal to send a notification of no load to the controller40. The controller40stops the control of the air-fuel ratio based on the oxygen density in response to this notification.
