Alcohol as a fuel for farm and construction equipment
Work in three areas dealing with the utilization of ethanol as fuel for farm and construction diesels is summarized. The first part is a review of what is known about the retrofitting of diesels for use of ethanol and the combustion problems involved. The second part is a discussion of the work that has been done under the contract on the performance of a single-cylinder, open-chamber diesel using solutions and emulsions of diesel fuel with ethanol. Data taken include performance, emissions and cylinder pressure-time for diesel fuel with zero to forty percent ethanol by volume. Analysis of the data includes calculation of heat release rates using a single zone model. The third part is a discussion of work done retrofitting a multicylinder turbocharged farm tractor diesel to use ethanol by fumigation. Three methods of ethanol introduction are discussed; spraying ethanol upstream and downstream of the compressor and prevaporization of the ethanol. Data on performance and emissions are given for the last two methods. A three zone heat release model is described and results from the model are given. A correlation of the ignition delay using prevaporized ethanol fumigation data is also given. Comparisons are made between fumigation in DI and IDI engines.
