Book Synopsis Hydrogen Fumigation on HD Diesel Engine by : Emad Monemian
Download or read book Hydrogen Fumigation on HD Diesel Engine written by Emad Monemian and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis An Experimental Investigation of Hydrogen Fumigation in a Small Direct-injection Diesel Engine During Part-load Operation by : William Enrique Marin
Download or read book An Experimental Investigation of Hydrogen Fumigation in a Small Direct-injection Diesel Engine During Part-load Operation written by William Enrique Marin and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen enrichment may offer enhanced performance of internal combustion engines. Hydrogen's high specific energy, wide flammability limits, and high flame speed are all desireable traits that can potentially enhance combustion. However, hydrogen's low energy density and its need to be produced from another energy source pose significant challenges for implementation. Hydrogen enrichment involves co-firing of hydrogen and another primary fuel. The hydrogen can be aspirated through the intake manifold via fumigation or injected at the port or cylinder with the primary fuel. The effect of hydrogen fumigation in diesel engines has been studied to some degree but is not fully understood. In this research, a single-cylinder four-stroke direct-injection diesel engine was modified for hydrogen fumigation and was instrumented to monitor combustion related performance parameters. This engine is representative of low-cost systems that are widely used in developing nations for agricultural and other low power applications. A factorial design of experiments was implemented to study the effects and interactions of hydrogen fumigation, injection timing, and diesel fuel flow rate on part-load engine performance. At relatively low energy fractions, hydrogen was found to have statistically insignificant effects on brake torque and indicated mean effective pressure, leading to modest decreases in brake thermal efficiency. Exhaust gas temperature increased with hydrogen enrichment. The coefficient of variance of indicated mean effective pressure decreased with hydrogen enrichment, and visible changes to the in-cylinder pressure trace were observed, particularly when injection timing was retarded. The results of this investigation show that for this specific configuration, hydrogen enrichment is not beneficial to the combustion process. The marginal improvements in coefficient of variance and changes of in-cylinder pressure cannot justify the decrease in thermal efficiency of the engine.
