Abstract
The current investigation acmes the ascendancy of ethanol on the performance, combustion and exhaust emissions of adulterated diesel fuelled compression ignition engine. Diesel adulteration by kerosene results in an adverse effect on performances and carbon emissions of the engine, but significantly reduces oxides of nitrogen. A small amount of ethanol incorporation into the adulterated diesel avowedly improves the performance, combustion and exhaust emissions of the engine. To this end, the engine is further modified for injecting hydrogen to reveal the competency of five different strategies along with 85% diesel, 5% kerosene and 10% ethanol blended fuel in volumetric proportion. The small amount of hydrogen enrichment aids in the improvement of brake thermal efficiency (up to 3.2%), brake specific energy consumption (up to 3.1%), in-cylinder pressure, heat release rate, brake specific hydrocarbon (up to 50.1%), brake specific carbon monoxide (up to 50.5%) and brake specific particulate matter (up to 44.8%) emissions.
