EU Normal operating conditions background section 6.1.2.4 of - PDF document

EU Normal operating conditions background • section 6.1.2.4 of Directive 2001/27/EC contains provisions on test conditions under which the engine must meet the emissions standards • These provisions are subject to review by the Commission. • The temperature / altitude distribution in the EU has been analysed through a collaboration between ACEA and the Aristoteles University in Tessalonniki to further evaluate the EURO3 current provisions concerning those normal operating conditions. File name MVEG 11 November 2002 1 EU Normal operating conditions selected criterion • Normal Operating Conditions consist of – minimum ambient temperature – maximum ambient temperature – maximum altitude. • The selection criterion for applying normal operating conditions was selected so that more than 90% of the vehicle kilometres within the EU would be driven within the 3 given conditions File name MVEG 11 November 2002 2 1

EU Normal operating conditions source of information • All the EU 15 countries have been divided into administrative regions accordingto the Nomenclature of Territorial Units for Statistics (NUTS) In order to take into account the differences between North and South, the Scandinavian countries and Spain have been further divided. • Altitude : http://www.calle.com/world/index.html. • Temperature: http://www.weatherbase.com • Annual vehicle kilometres driven by each HDV class are taken from TRENDS for reference year 1995 File name MVEG 11 November 2002 3 EU Normal operating conditions distribution analysis EU veh.km / temperature / altitude distribution 30,0% 25,0% v e h . k m f r e q u e n c y 20,0% 15,0% 10,0% < 5,0% 1 0 0 m 4 0 0 0,0% - 5 0 0 > m altitude 8 0 0 m temperature File name chart developped on data originating from LAT (Greece) MVEG 11 November 2002 4 2
