Driving cycle economy, emissions and photo-chemical reactivity using alcohol fuels and gasoline
An oxidation catalyst-equipped vehicle and several 3-way-catalyst (TWC)-equipped vehicles were modified to operate on gasoline or alcohol fuels. Unburned hydrocarbon emissions were generally lowest when methanol fuel was used. The amount of NOx were reduced an average of greater than 50% by using alcohol fuels in contrast to gasoline. Photochemical reactivity comparisons of unburned fuel emissions were made by calculation and in a 100-ft3 smog chamber. Synthetic stoichiometric methanol exhaust was less photochemically reactive than gasoline exhaust for the 8.5:1 compression ratio engine conditions. The exhaust from the stoichiometric TWC - equipped vehicles was extremely low in calculated and experimental reactivities for both methanol and gasoline fuels.
