Abstract
A control system for a spark-ignited gaseous fuel engine includes a fuel quality sensing mechanism, and a control device structured to receive data produced by the fuel quality sensing mechanism indicative of a change in energy content of a stream of gaseous fuel and air, and to vary an amount of an augmenting fuel that is injected into the stream of gaseous fuel and air based on the data. The strategy has application to low energy gaseous fuel and air mixtures such as are produced in mine ventilation.
