CONTROL SYSTEM AND METHOD FOR MULTI-FUEL GENERATOR ENGINE

A control system and method for a multi-fuel generator engine are mainly applied to multi-fuel generator products. The control system comprises a controller, a first signal input terminal, a second signal input terminal, a third signal input terminal, and an output terminal connected to an ignition device of a generator engine. When the third signal input terminal of the controller receives a generator engine start signal and either the first signal input terminal or the second signal input terminal receives a signal corresponding to an on state of the corresponding valve assembly, the controller controls the ignition device to ignite. According to control system and method, the controller detects signals corresponding to the states of the two fuel valve assemblies to determine whether or not fuels are normally supplied, so that operating instabilities or faults caused by synchronous supply of two fuels to the generator engine are avoided.
