Özet

In this experimental work, the variations of cylinder pressure and exhaust emissions using ethanol diesel fuel mixtures with different blends and compression ratios in a diesel engine are reported. Experiments are carried out using an ASTM-CFR monocylinder test engine, operated at constant engine speed and without loading. Comparison of the results with standard Eurodiesel fuel combustion experiments indicate that NOx, soot, and CO emissions decrease, whereas CO2 emissions increase with increaseed ethanol concentration. An increase in the compression ratio results in a decrease in NOx and CO2 emissions and an increase in CO and soot emissions.
