The presentation culminates in a selection and rating chart for alternative fuels based upon different goals that may be required for future markets.本报告针对各种替代燃料在未来发动机上的应用潜力进行讨论。由于 CO2 排放法规、石油资源自主性和能源效率的不同，各国对于替代燃料的选择亦会 不同。比如，美国在过去几年中不断增加

13、对乙醇代用燃料的使用，希望藉此降 低对石油的需求。这一举措虽然成功地满足了这一目标，但用于汽车工业的乙 醇燃油成本却远远高于石油。由此导致的结果是，为降低石油消耗，人们不得 不接受能源效率低下的事实。美国西南研究院开发的用于乙醇或其它混合燃料 的冷却 EGR 技术，不但可以有效减少对石油燃料的使用，同时也能很好地满足 乙醇或其它动力车辆的燃油经济性和工况范围要求。替代燃料(如天然气、乙 醇、甲醇)的使用将可能成为实现 CO2 排放法规的更有效途径；为此，本报告 增加了对替代燃料降低 CO2 排放潜力的分析，以及各种替代燃料的燃效和成本 方面的内容。报告中的高潮部分还根据未来市场的不同需求目标，

14、给出了各种 替代燃料的选择评价图。2、低排高效的天然气发动机技术Natural Gas Engine Technology for Low Emissions and High EfficiencyMr. Timothy J CallahanThis presentation will discuss technology for natural gas engines that enable them to achieve low emission while maintaining high efficiency.

As emission regulations have beco

17、me increasingly restrictive, diesel engine emission levels are approaching those of natural gas engines. However, the diesel engines require expensive aftertreatment and engine combustion strategies that lead to higher specific fuel consumption. With the appropriate technologies, the performance and

18、 emissions of gas engines can exceed the diesel engine or otheralternatively fuelled engines.在美国（和其它地区）一些环境空气质量恶劣的地区，重型天然气发动机 已被广泛应用于汽车运输业。随着排放法规的日益严格，柴油机的排放水平逐 渐接近天然气发动机。但是，柴油机需要用到昂贵的后处理装置，且各种燃烧 策略的运用直接导致燃油耗增加。如果能够采用适当的技术，气体发动机的性 能和排放完全可以超越柴油机或其它替代燃料发动机。In addition to low emissions, natural gas can

19、 also be used as a petroleum fuel substitute or extender as in the case of dual fuel engines. Two dual fuel engine scenarios are common. The first scenario is a dedicated dual fuel engine in which a small diesel pilot injection is used to ignite the natural gas air charge and the ratio of pilot ener

20、gy to natural gas energy is about 1:100. In the second scenario, full diesel engine capability is retained and natural gas is used to replace the equivalent diesel energy. That is as natural gas is added to the combustion mixture, the equivalent energy of diesel fuel is removed. In this case the per

21、centage of natural gas substitution ranges from 15-85 percent.除排放低外，天然气可以替代石油燃料，或作为双燃料发动机的混合添加 物。现有两种双燃料发动机比较普遍。第一种是专门的双燃料发动机，只预喷 少量的柴油用于引燃天然气，预喷的柴油与天然气的能量比约为1:100。第二种双燃料发动机则保留了全部的柴油机性能，但用天然气替代具有等效能量的柴 油。即，将天然气添加到燃烧混合物的同时，释放具有等效能量的柴油。这种 情况下天然气对柴油的替代比率在 15-85%Technologies discussed include the igniti
