Abstract

The high cetane number of the fuel used in diesel engines is extremely importantas it provides some improvements in combustion in the cylinder. Therefore, theaddition of cetane improver to diesel fuel has been highly preferred in recent years.In this study, the effects of 2-ethylhexyl nitrate (EHN) addition, a cetane improver,on compression ignition engine performance and emissions were analyzed atvarious engine loads. Four different fuels were used in the experiments as 100%diesel (D100), 99% diesel + 1% EHN (D99EHN1), 98% diesel + 2% EHN(D99EHN2) and 97% diesel + 3% EHN (D99EHN3). The results obtained fromthe experiments showed that the addition of 2-EHN positively affected the brakethermal efficiency (BTHE), hydrocarbon (HC) and carbon monoxide (CO) values,while the brake specific fuel consumption (BSFC), nitrogen oxide (NOx) andsmoke emission levels were negatively affected. With high engine load, 2-EHNsupplement marginally rises NOx emissions but significantly declines HC and COemissions. EHN addition had small impacts on BSFC. Compared to D100 fuel,the highest BTHE value was obtained by D99EHN2 fuel, with an increase of11.57% at 3000-Watt load value. With the D97EHN3 fuel, compared to diesel,HC emission decreased 60.61%, while CO emission decreased 31.25%. Theresults show that the 2-EHN cetane improver can be used successfully in a dieselengine.
