| Popis: | There is a global interest in the use of alternative fuels due to environmental concerns such as greenhouse emission, ozone depletion, air pollution. Also, the limited petroleum reserves invite the alternate solution for diesel engines. Several researchers have proposed various types of solutions. One among them is the use of different gaseous fuels with pilot diesel fuel. An experimental work has been done to find the performance of high-capacity diesel engine which uses diesel fuel with the variation of hydrogen and rice-husk-derived producer gas. The results of engine test with producer gas and hydrogen on brake thermal efficiency and emissions such as unburnt hydrocarbon, carbon monoxide, and NOx are presented. Beyond 30% load, the brake thermal efficiency of dual-fuel operation is improved. Maximum efficiency of 38–43% is achieved with mixture of 10% PG and varying hydrogen from 5 to 25% and similarly for mixture of 40% PG and varying hydrogen gives the maximum efficiency of 43–48% at 60% load condition. It is found that specific energy consumption increases with the increase in PG and hydrogen flow through inlet of engine. The maximum fuel substitution has been found at 80% load with 10% PG and 25% hydrogen mixture. At higher loads, volumetric efficiency has been better as the oxygen or air intake would be more, but at mixture of 40% PG and 25% hydrogen, the volumetric efficiency reaches a level of 27% as there is sufficient amount of PG and hydrogen, but minimum intake of air took place. The higher CO and HC emission levels were recorded for increased producer gas content due to the CO content. Nox emissions were maximum at higher loads due to the presence of nitrogen in air as well as fuel. Overall smooth running of engine is found in all cases. One major finding of the experiment is that the mixture of PG and hydrogen is an alternative fuel with good efficiency. |
