Performance comparisons of spark-ignition engine fueled with butanol/gasoline and ethanol/gasoline blends

摘要

The performance comparisons of engine fueled with butanol/gasoline and ethanol/gasoline blends were tested. It was indicated from the experimental results that, compared with pure gasoline, power and fuel economy of engine fueled with butanol/gasoline and ethanol/gasoline blends reduced slightly, while HC and CO emission reduced significantly, and NO emission increased. It can be concluded that, the performance of engine fueled with butanol/gasoline blends was better than ethanol/gasoline blends, and B20 was better than B30.
