Determination of Pollutant Emissions Characteristics of General Electric CF6-6 and CF6-50 Model Engines
Abstract
The average levels and the variability of emissions were determined for newly manufactured General Electric CF6-6 and CF6-50 model engines. Emissions of carbon monoxide, hydrocarbons, oxides of nitrogen, and smoke were measured on a total of twenty-five engines. Emissions were measured from two separate sampling sysems, one sampling in the FAA diamond pattern, and the other in the EPA cruciform pattern. Only small differences in emissions were found between the two sampling patterns. Typical variability in CF6 production engine emissions was found to be somewhat less than had been previously reported for other types of large, turbofan engines. The effect of differences in fuel types, and in idle conditions (hot or cold) on emission levels were also determined.
