ABSTRACT:
An internal combustion engine is fueled with a controlled mixture of natural gas and air which mixture is regulated by a regulator responsive to an electronic controller. In the event of a system failure with the electronic controller shutting down, a backup regulator automatically bypasses the normal regulator to provide temporary operation with a predetermined acceptable constant gas mixture.
