Abstract
⺠We performed optical measurements in a GDI engine for two wheels vehicles. ⺠We investigated two injection pressures in two engine condition using two fuels, gasoline and pure ethanol. ⺠Gasoline spray was more sensible to changes in injection pressure than ethanol's. ⺠At low speed and load ethanol combustion showed faster burning rates and so higher peak pressures than gasoline. ⺠Ethanol combustion shows less diffusive flames than gasoline, associated with lower levels of soot.
