1Transportations Contribution to California Emissions2Vehicle Emissions Depend OnHow clean is the fuelReduces engine out emissionsMaximizes efficiency of aftertreatmentHow well the fuel is combustedCombustion chamber design, fuel control, etc.How effectively the exhaust is treated33Cleaner Burning GasolineGasoline1992 Phase I Cleaner Burning GasolineEliminated lead in gasoline.RVP reduced from 9.0 to 7.8 psi.Applies during warmer weather monthsEvaporative emissions benefitRequired the addition of 10% oxygenates. 1996 Phase II Cleaner Burning GasolineSulfur levels reduced from 151 ppmw to 30 ppmwRVP reduced to 7.0 psiEvaporative emissions benefitReduced ozone precursors by 300 tons/day. Equivalent to taking 3.5 million cars off the road. 2002 Phase III Cleaner Burning GasolineProhibited use of MTBE as oxygenate - replaced by ethanolSulfur levels reduced to 15 ppmw
