Abstract
In this study, performance and exhaust emissions of a direct injection diesel engine fuelled by diesel-jojoba-butanol blends was performed. Mixtures of crude jojoba oil, diesel fuel and butanol were selected as the test fuel. The tests were made in two sections. Firstly, the measured performance and exhaust emissions of the diesel engine operating with diesel-jojoba-butanol blends over a wide range of load conditions and a constant speed of 1500 rpm are determined and compared to determine the best ratio of butanol in the blend substitution of the diesel fuel. Among the test cases, the blend with 87% diesel fuel, 5% crude jojoba oil and 8% butanol (DJ5B8) has shown the best performance with respect to the specific fuel consumption (BSFC), exhaust gas temperature (EGT) and brake thermal efficiency. Carbon monoxide (CO) and unburned hydrocarbon (HC) were lower with DJ5B8 blend while nitrogen oxides (NOx) were higher than diesel fuel operation. Secondly, emulsified DJ5B8 blend of 0%, 5%, 10%, 15% and 20% hydrogen peroxide or water by volume were used to improve the engine performance and exhaust emissions. The results showed that, in all cases, the hydrogen peroxide or water content in the emulsified fuel decreased both the NOx emissions and exhaust gas temperatures. Adding 5% hydrogen peroxide to DJ5B8 blend causes to achieve the best performance result than the other emulsified fuel ratios.
