Abstract:
A method for responding to detection of an open fault condition in a gaseous fuel admission valve for providing a flow of gaseous fuel to an affected combustion cylinder of an engine, the engine including at least one other gaseous fuel admission valve for providing a flow of gaseous fuel to at least one other combustion cylinder, a gaseous fuel shut off valve for controlling gaseous fuel flow from a source of gaseous fuel to a gaseous fuel manifold in communication with the gaseous fuel admission valves, and means for igniting a mixture of the gaseous fuel and air in each said combustion cylinder, the method comprising the steps of:(a) closing the gaseous fuel shut off valve; and(b) disabling the means for igniting the mixture of gaseous fuel and air in the affected combustion cylinderonly, while operating the at least one other gaseous fuel admission valve for allowing flow of remaining gaseous fuel in the gaseous fuel manifold through the at least one other gaseous fuel admission valve to the at least one other combustion cylinder of the engine.
