為了因應全球暖化加劇及石油短缺的現象日益嚴重,世界各國致力發展替代內燃機之新型能源車輛以降低溫室氣體排放及減緩石油用量。氫燃料內燃機引擎在作為汽車動力裝置方面在現今已被全世界公認為非常有潛力汽車動力。特別的是,氫燃料內燃機引擎運轉時幾乎接近零排放汙染,以及其運轉的熱效率超過一般汽油內燃機引擎、柴油內燃機引擎及液化石油氣(LPG)內燃機引擎等都已經被證實。 因此本文應用內燃機引擎運轉模擬軟體ME636,及模擬從原油生產成汽油及汽車引擎使用各種燃料運轉後排出溫室氣體分析的軟體GREET1.8。對汽油內燃機引擎、柴油內燃機引擎、液化石油氣內燃機引擎、氫直接噴射內燃機引擎以及氫內燃機引擎等五種引擎,分析此五種引擎在運轉時其個別的熱效率,以及應用GREET1.8來模擬分析目前全球都關注車輛運行所會排出的溫室氣體如一氧化碳(CO)、硫氧化物(SOX)、氮氧化物(NOX)、碳氫化合物(HC)與黑煙(smoke)等氣體來做分析探討[1~3]。
Facing the problems of the aggravating global warming effects and the shortages of fossil fuel, countries over the world have devoted in developing cars facilitated with alternative internal combustion engines. There by reducing people’s use and the amount of pollution associated with them has been the main issue. Hydrogen internal combustion engine has been accepted as potential ones as electric power generator installations. What special is that it generates electricity with nearly zero pollutions in the processes and its thermal efficiency has also proven to surpass the average gasoline、diesel and liquid petroleum engines. Therefore, this article applies the theories of the simulating software, ME636 of the internal combustion engines, analysizing the individual effective thermal efficiency of these five engines,and use simulated software GREET 1.8of all the procedures of refining crude oil into gasoline to simulated performed in the assay procedures, including CO2, SOx, NOx, HC and smoke released by vehicles.
