- Abstract
Disposal of hazardous waste engine oil (WEO) has become the forefront of climate change. Hence, the potential conversion of WEO is essential and also recycled through different pyrolysis techniques for better assessment. In this work, diesel-like fuel extracted from electrical pyrolysis and microwave pyrolysis was used as an alternative fuel for the CI engine. The pyrolysis oil generated by both pyrolysis processes was found to be reliable. Nevertheless, the physicochemical characteristics of both pyrolysis oil deviated from each other. The performance, combustion and emission characteristics of different pyrolysis fuel have been investigated to identify the suitable alternative fuel for CI engine. The performance characteristics at rated load revealed that the brake thermal efficiency of electrical pyrolysis oil (EPO) and microwave pyrolysis oil (MPO) was 26% and 25%, respectively, which was 0.8% and 1.5% lower than diesel due to its higher viscosity. Emission characteristic shows that unburnt hydrocarbon emission of EPO and MPO was higher than diesel by 7% and 15%, respectively. Similarly, the filter smoke number was 3% and 10% higher than diesel. NO emission of EPO and MPO was lower than diesel by 27% and 13%, respectively. Also, exergy analysis represents MPO has higher potential when compared to EPO due to higher exergy efficiency.
