| Sumario: | The currently reported work was concerned with experimental and numerical evaluation of the potential to partially replace diesel with hydrogen fuel, which continues to attract attention as an alternative longer-term fuel solution. The experimental work was involved with the fumigation of hydrogen on a single cylinder HD diesel engine under two real-world driving conditions at low and mid loads. Highest practical hydrogen substitution ratios could increase indicated efficiency by up to 4.6 and 2.4% while reducing CO2 emissions by 58 and 32% at low and mid loads, respectively. Soot and CO emissions were reduced as more hydrogen was supplied, particularly at low load. The numerical study was made by using two distinct phenomenological models being run in parallel. While, an in-depth evaluation of the unique dual fuel combustion was possible, the arising errors were largely associated with lack of dual fuel burning velocity data, which will remain a key barrier to dual-fuel simulation. |
