摘要： A method for adjusting a fuel control system of an engine capable of operating in both a first mode during which only a first fuel is delivered to the engine and a second mode during which both the first fuel and a second fuel are delivered to the engine includes operating the engine in the first mode during which a governor output value (X.sub.M1) is established and stored in memory. The engine is then operated in the second mode during which a governor output value (X.sub.M2) is established. The governor output value (X.sub.M2) is compared with the stored governor output value (X.sub.M1) and a stored second fuel energy content value is adjusted based upon the comparison. The actual energy content of the second fuel can also be directly calculated.

摘要： 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.

摘要： A direct injected gas engine system is made more suitable for use with a fuel of natural gas by a fuel control system providing variable gas pressure control to reduce gas pressure compared to that applied at full load, and extend fuel pulse duration for light loads as compared to fuel pulse duration at light loads if applied at the full load gas pressure. The light load fuel pulse duration can now be extended to be at least as long as the ignition delay period of the engine. A variable gas pressure regulator under the control of the engine's electronic control module provides the desired gas pressure control. Engine speed and load parameters are used to monitor engine conditions and provide signals to the electronic control module, which may use them to set the appropriate pressure in a map mode. The apparatus and method of operation improves efficiency and lowers emissions at light loads.
