dc.description.abstractNon-volatile particulate matter (nvPM) emissions from aircraft turbine engines affect local air quality and climate. Due to the steady growth of air traffic, concerns about environmental and health effects of aircraft engine nvPM emissions increase. Thus, researchers and regulators have focused on nvPM emissions mitigation strategies and improved estimates of aviation nvPM emissions. Recently, the International Civil Aviation Organization (ICAO) adopted an nvPM emission standard for aircraft turbine engines. This standard will limit nvPM mass and number emissions from the ICAO landing and take-off (LTO) cycle of new aircraft engines and will retire the current smoke number (SN) standard. SN has been historically used for estimating nvPM mass emissions. To improve the prediction of nvPM emissions of SN-certified engines, various predictive models have been developed, such as the recent SCOPE11 method based on simultaneous SN and nvPM mass and number measurements. These models enable estimating nvPM mass and number emissions from the LTO cycle using certification SN in the ICAO emissions databank. However, the certification SN may not be representative for in-service engines due to deterioration effects. In this work, we present nvPM emission characteristics of different models of widely used in-service turbofan engines. The data are based on several years of engine emissions testing in an engine test cell at SR Technics, Zurich airport. The sampling and measurement system is a reference system for nvPM measurements according to the new ICAO standard. Besides nvPM mass and number emissions, we measured particle size distributions, SN, and gaseous pollutants (CO, NOx, and HC). Our simultaneous measurements of SN and nvPM mass show very good agreement with previously established correlations. Yet, compared to estimates obtained from SN-nvPM mass correlation using SN data from emissions certification of new engines, the maximum nvPM mass emissions of in-service engines were higher by up to a factor of 3. We further evaluate the variability of nvPM emissions for individual engine types and the correlation of nvPM emissions with engine maintenance status and performance deterioration. The aim of this work is to provide improved estimates of nvPM emissions from in-service aircraft.de_CH
