| Abstract | ||
| Several Experiments have been done to evaluate the effect of blending kerosene (by different volume) with diesel fuel on the performance and emissions of a single cylinder 4-stroke air cooled DI diesel engine connected with a hydraulic dynamometer which is used to load the engine that running at fixed speed with different loads (torques). Two levels of blend 10% and 20% of kerosene blending by volume with diesel fuel were named KD10 and KD20 respectively, while pure diesel was considered as a baseline and named D. The engine speed was running at constant speed 1500 rpm.the treatments include three levels of load (torque) 2, 6 and 10 N.m and three types of fuels D, KD10 and KD20. Performance parameters that were studied involve brake specific fuel consumption (bsfc), brake thermal efficiency (BTE), brake specific energy consumption (bsec), Exhaust Gas Temperature (EGT) and sound level. Furthermore, the exhaust emissions were analyzed to find the effect of selected blends on Carbon Dioxide (CO2) and Nitrogen Oxides (NOx). The results showed the possibility of using KD10 in diesel engine instead of diesel fuel D without any modification done on the engine as there is no significant difference registered in bsfc, BTE and bsec at full load, while using KD10, KD20 recorded a decrease in CO2 emissions by 8.8% and 27.3% respectively compared to fuel D at high loads also they recorded an increase in NOx emissions by 16.6% and 31.2% respectively compared with using diesel fuel . The results showed that using KD10, KD20 instead of fuel D showed an increase in EGT and sound level for all ranges of selected torques | ||
