Abstract
Fumigation, inline mixing, chemically stabilized emulsions and cetane improvers were evaluated as a means of using ethanol in diesel engines. Two turbocharged six-cylinder engines of identical bore and stroke were used, differing in combustion chamber type.
Three alcohol proofs were evaluated: 200, 190, and 160. Alcohol was added at the following concentrations: 10, 25, and 50% except in the case of the cetane-improved alcohol. In the latter case a commercial ignition improver for diesel fuel, DII-3, was added to neat alcohol in the proportions of 10, 15, and 20%.
Generally, the emissions of CO, total hydrocarbons, and oxides of nitrogen reflected the trends observed in the thermal efficiencies. At light loads, CO and HC emissions were higher than baseline, decreasing to near baseline levels at heavy loads accompanied with higher NOx.
