ABSTRACT:
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.
