近年来，利用金属胺配合物储存氨的研究日益受到关注。本文分析了一种以金属胺配合物为氨燃料的内燃机燃料系统。在同样的背景下，研究了氨/氢混合物作为硅发动机燃料的使用。将氨气和氢气引入cfr发动机进气歧管。进行了不同过量空气比和不同氨氢比的一系列实验。结果表明，氢含量为10%的燃料混合物在效率和功率方面表现最好。与汽油的比较表明，由于压缩比可能更高，效率和功率都有所提高。系统分析表明，利用余热可以覆盖大部分必要的热量。建议采用经处理后的SCR作为废气来降低高NO(x)排放。(C) 2010 Elsevier Ltd.版权所有。
In recent years there has been increasing focus on using metal ammine complexes for ammonia storage. In this paper a fuel system for ammonia fuelled internal combustion engines using metal ammine complexes as ammonia storage is analyzed. The use of ammonia/hydrogen mixtures as an SI-engine fuel is investigated in the same context. Ammonia and hydrogen were introduced into the intake manifold of a CFR-engine. Series of experiments with varying excess air ratio and different ammonia to hydrogen ratios was conducted. This showed that a fuel mixture with 10 vol.% hydrogen performs best with respect to efficiency and power. A comparison with gasoline was made, which showed efficiencies and power increased due to the possibility of a higher compression ratio. The system analysis showed that it is possible to cover a major part of the necessary heat using the exhaust heat. It is proposed to reduce the high NO(x) emissions using SCR as exhaust after treatment. (C) 2010 Elsevier Ltd. All rights reserved.
