8 Impact of Fuels on Light-Duty t Diesel Vehicles Diesel Fuel Characteristic i Pre Euro Euro 1 Euro 2 Euro 3 Euro 4 Euro 5 a Comments Sulfur SO 2, PM If oxidation catalyst is If filter, 50 ppm used, SO 3, SO 2, PM maximum, ppm better If NO X adsorber used requires near zero sulfur (<10 ppm) With low S, use lubricity additives. Cetane Lower CO, HC, benzene, 1,3 butadiene, formaldehyde & acetaldehyde Higher white smoke with low cetane fuels. Density PM, HC, CO, formaldehyde, acetaldehyde & benzene, NO X Volatility NO X, HC, PM, CO (T95 from 370 to C) Polyaromatics NOX, PM, formaldehyde & acetaldehyde but HC, benzene & CO Some studies show that X,, y y, total aromatics are important for emissions in a manner similar to polyaromatics Source: ADB and CAI-Asia

9 Impact of Fuels on Heavy-Duty Diesel Vehicles Diesel Fuel Characteristic i Pre Euro Euro 1 Euro 2 Euro 3 Euro 4 Euro 5 a Comments Sulfur SO 2, PM If oxidation catalyst is If filter, 50 ppm used, SO 3, SO 2, PM maximum, ppm better If NO X adsorber used requires near zero sulfur (<10 ppm) With low S, use lubricity additives. Cetane Lower CO, HC, benzene, 1,3 butadiene, formaldehyde & acetaldehyde Higher white smoke with low cetane fuels. Density HC, CO, NO X Volatility Slightly lower NO X, but HC Too large a fraction of (T95 from 370 to fuel that does not C) volatilize at C increases smoke and PM. Polyaromatics NOX, PM, HC Some studies show that total aromatics are important for emissions in a manner similar to polyaromatics Source: ADB and CAI-Asia

10 Impact of Gasoline Composition on Emissions from Light- Duty Vehicles Gasoline No Catalyst Euro 1 Euro 2 Euro 3 Euro 4 Euro 5 b Comments Lead Pb, HC CO, HC, NO X all increase dramatically as catalyst destroyed Sulfur SO HC, NO all increase ~15 20% Onboard diagnostic light may come 2 CO, X cease (50 to 450 ppm) SO 2 and SO 3 increase on incorrectly Olefins Increased 1,3 butadiene, increased HC reactivity, and NO X, small increases in HC for Euro 3 and cleaner Potential deposit buildup Aromatics Increasedbenzeneinexhaust exhaust Deposits on intakevalves and combustion chamber tend to increase Benzene Distillation Characteristics T50, T90 potential increases in HC, NO X HC, NO X, CO HC, NO X, CO Increased benzene exhaust and evaporative emissions Probably HC HC RVP Increased evaporative HC Emissions Most critical parameter for Asian countries because of high ambient temperatures Deposit control Potential lhc, NO i Helpto reducedeposits X emissions benefits deposits on fuel additives injectors, carburetors, intake valves, combustion chamber Source: ADB and CAI-Asia

But government should leapfrog to Euro-IV and V as soon as possible HCV LCV PC MC three MC two 12
