Direct injected gas engine with variable gas pressure control apparatus and method of operation

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