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： Machine assemblies often include driving and driven members such an engine associated with a driven load. These members typically include rotatable shafts (16, 18) interconnected by a flexible coupling element (20). System torsionals in such a machine often cause the shafts (16, 18) to be out of phase with one another. When this occurs, excessive energy is transferred to the coupling element (20). The subject apparatus (22) includes a device (24) for detecting and measuring rotational phase differences between driving and driven rotatable shafts (16, 18). The measured phase differences are compared with a reference phase difference level and an error signal is produced in response to the measured phase difference exceeding the reference level.
