Özet
In this study, the effect of cottonseed oil methyl ester addition in eurodiesel fuel on the combustion, performance, and exhaust emissions of a direct injection single-cylinder diesel engine was investigated. Experiments were carried out at constant engine speed (1500 rpm) at different engine loads.The cottonseed oilmethyl ester blends obtained by mixing 10%, 20%, and 50% of the cottonseed oil methyl ester with eurodiesel fuel (called PYME10, PYME20 and PYME50 respectively) and eurodiesel fuel(PYME0) were usedin the experiments.The obtained fuels were tested in a single-cylinder, four-stroke, air-cooled diesel engine loadable with electric dynamometer, and the results were compared to the reference eurodiesel. The results showed that the ignition delay of the cottonseed oil methyl ester mixtures was longer than the eurodiesel. The maximum cylinder pressure is higher for all engine loads than for the eurodiesel. The heat release rate of cottonseed oil methyl ester mixtures is higher than the eurodiesel. Eurodiesel has the lowest specific fuel consumption and highest thermal efficiency compared to cottonseed oil methyl ester mixtures for all engine loads. PYME10, PYME20 and PYME50 mixtures follow eurodiesel respectively. It has been observed that cottonseed oil methyl ester addition causes a slight increase in NOx emissions while causing a decrease in smoke and CO emissions, HC emissions were observed to low values.
