STUDY THE EFFECT OF BLENDING KEROSENE WITH DIESEL FUEL ON THE PERFORMANCE AND EMISSIONS OF DIESEL ENGINE

An Experiment al study wa s conducted to enaluate 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 running at fixed speed with different loads (torques). Two levels of b lend 10% and 20% of kerosene blending by volum e with diesel fuel were named K10 and K20 respectively, while pure diesel was considered as a base line and named D . The tr eatments include engine speed that was running at constant speed 1500 rpm , with th ree le vels of load (torque) 2, 6 and 10 N.m and three types of fuels D, K10 and K20 . Performance parameters that were studi ed involve b rake specific fuel consumption, brake thermal efficiency and exhaust temperature . Furthermore, the exhaust emissions were analyzed to find the effect of selected blends on nitrogen oxides (NOx) and carbon dioxide (CO 2 ).emissions. Results showed that the bsfc has been reduced by 14.1 % and 20.1% when engine fueled with K10 and K20 respectively at low load compared with pure di esel. Exhaust gas temperature, BTE, CO 2 and NO x concentration have been increased when engine fueled with K10 and K20 instead of diesel fuel(D).These results indicted the possibility of using blending kerosene (by 10% and 20% by volume )with diesel fuel wi thout any modification in the engine
