Abstract
The present disclosure refers to a gas fuel admission system for a gas fired engine. A gas pressure regulating unit includes a gas pressure regulating unit inlet and a gas pressure regulating unit outlet. The gas pressure regulating unit is configured to receive gas and to discharge the gas at an injection pressure. An engine gas inlet is configured to direct gas into the at least one combustion chamber. A gas admission valve is configured to admit the gas having an injection pressure at a predetermined time for a predetermined duration into the engine gas inlet. A gas pressure relief device is fluidly connected to the gas conduit and it is configured to relieve overpressure of the gas in the gas supply conduit, if a pressure differential between the injection gas pressure and the intake air pressure is above a predetermined threshold. A specific engine control module is configured to control the gas admission valve in response to inputs from various sensing devices.
