  1. INFLUENZA DEL PARAMETRO “ltrip “ SULLA STIMA DELLE EMISIONI

  2. ltrip influenza le emissioni a freddoEcold = b*N*M * ehot *(ecold/ehot –1) • Ecold = Emissioni a freddo • b = frazionedella percorrenza condotta con il motore freddo o con il catalizzatore operante al di sotto della temperatura di “light-off”. • ehot =Fattore di emissione a caldo • eCOLD/HOT=Over-emission ratios per l’inquinante specifico

  3. b=0,6474-0,02545*ltrip-(0.00974-0.000385*ltrip)*ta8 km<ltrip<15 kmltrip influenza anche le emissioni evaporative.
