    Abstract: A method for responding to detection of an open fault condition in a gaseous fuel admission valve (30) for providing a flow of gaseous fuel to affected combustion cylinder (14) of an engine (12), the engine (12) including at least one other gaseous fuel admission valve (30) for providing a flow of gaseous fuel to at least one other combustion cylinder (14), a gaseous fuel shut off valve (38) for controlling gaseous fuel flow from a source of gaseous fuel to a gaseous fuel manifold (32) in communication with the gaseous fuel admission valve (30), and apparatus for causing ignition of a mixture of the gaseous fuel and air in each combustion cylinder (14). The present method involves the steps of closing the gaseous fuel shut off valve (38); disabling the ignition of the mixture of gaseous fuel and air in the affected combustion cylinder (14); and continuing operation of the at least one other gaseous fuel admission valve (30) to allow flow of remaining gaseous fuel in the gaseous fuel manifold (32) through the at least one other gaseous fuel admission valve (30) into the at least out other combustion cylinder (14) of the engine (12) where the gaseous fuel can be combusted. In the instance of an engine (12) operating in a dual fuel mode, at a suitable point, operation can be shifted to a liquid fuel mode. In the instance of an engine (12) that operates solely on gaseous fuel, once the gaseous fuel remaining in the gaseous fuel manifold (32) is exhausted, the engine (12) will come to rest.
