Abstract

Oxygenated fuels have been found to reduce particulate matter (PM) from compression-ignition (diesel) engines while improving or maintaining acceptable levels of other regulated emissions (NOx, hydrocarbon (HC) and CO). To gain further insight on the effect of oxygenates on diesel engine PM emissions, Accelerator MS was used to investigate the relative contribution to soot from the ethanol and diesel fractions of blended fuels. A trend towards PM emissions was observed with high levels of oxygenate. Homogenous cosolvent blends were more effective in reducing PM emissions compared to emulsified blends. NOx emissions from ethanol-in-diesel blends were 22-27% lower than that of the baseline diesel and did not show large variation across the different blends. Emissions of HC and CO increased but remained low as is typical with diesel engine combustion.
