| description | A fuel pressure relief system for a dual fuel engine including at least one gaseous fuel admission valve positioned between a gaseous fuel inlet region and an air intake region is provided. The system includes a first pressure sensor positioned in the gaseous fuel inlet region and a second pressure sensor positioned in the air intake region. An electronic controller is connected to the first pressure sensor and the second pressure sensor. A gaseous fuel vent path extends between the gaseous fuel inlet region and a portion of an air intake path of the engine. A vent valve is positioned along the gaseous fuel vent path and is connected to the electronic controller for control thereby. When the differential pressure across the gaseous fuel admission valve exceeds a predetermined level the fuel vent valve is opened to relieve the pressure. |
