    Abstract
  • On the basis of engine performance model, the effects of performance deterioration on engine pollution emissions, such as NOx, CO, UHC and Soot, were studied, and an estimation method of total emissions in flight based on flight parameters and engine performance model was proposed.By fitting ICAO emission data, the reference emission indices of engine under ground condition were obtained, the emission indices in flight were calculated by using the reference emission model, and the total emissions in flight were calculated based on flight parameters and engine performance model.Study result shows that engine performance deterioration has great effects on the emission indices.When considering the impact of fuel flow, the performance deterioration has less impact on NOx emission, but makes the total emissions of CO, UHC and Soot increase.For a modern turbo fan engine in a middle range flight, the total emission of NOx is about 100 kg, CO about 20 kg, and both UHC and Soot less than 1 kg.Engine performance deterioration results in an increase of about 10% for the total emissions of CO, UHC and Soot, but about 2% for NOx.
