A combustor utilizing concepts of swirling flow and orifices in order to optimize mixing rates was developed for application in low-emissions automotive gas turbine engines. Low emissions were obtained at one operating condition with a fixed-geometry configuration. Addition of a variable opening in the dome of the combustor provided low emissions over the expected operating range for an automotive gas turbine engine. Emissions of NOx obtained on a simulated Federal driving cycle were near the Federal statutory limit, and emissions of CO and HC were considerably lower.
