A lot of research is being carried out to reduce the environmental pollution resulting from compression ignition engines. For this, various gaseous fuels are being explored as fuel additives in compression ignition engines. The purpose of this research work is to investigate rarely explored Brown's gas (oxyhydrogen gas) in CI engines to reduce environmental pollution. Brown's gas was produced by electrolysis of distilled water with potassium hydroxide as a catalyst. A common rail direct injection CI engine was used for the present investigation. Detail combustion, performance, and emission analyses were carried out, which is scarcely reported in oxyhydrogen gas fuel investigations in compression ignition engines. Oxyhydrogen was injected at varying flow rates of 200 ml/min, 400 ml/min, 600 ml/min, and 800 ml/min in the intake manifold of the CI engine equipped with an electronically controlled common rail direct injector. The peak pressure and maximum heat release rate increased with the increasing concentration of oxyhydrogen gas. The comparison was made between conventional diesel combustion and oxyhydrogen gas addition of 800 ml/min at 75% load. The reduction in CO and HC emissions was about 37.5% and 17.94% respectively. CO and NOx emissions increased by 9.37% and 7.41% respectively. Very low smoke emission of 0.01 to 0.02% was recorded at 800 ml/min oxyhydrogen gas flow rate. Thus, it can be concluded that oxyhydrogen gas provides promising benefits in terms of better combustion and low emissions. However, it is recommended to carry out further research to incorporate the use of this additive in actual automobile applications.
为减少压燃式发动机造成的环境污染，人们正在开展大量研究。为此，正在探索各种气体燃料作为压燃式发动机的燃料添加剂。本研究工作的目的是研究在压燃式发动机中鲜少被探索的布朗气体（氢氧气体），以减少环境污染。布朗气体是通过以氢氧化钾为催化剂对蒸馏水进行电解产生的。本研究使用了一台共轨直喷式压燃式发动机。进行了详细的燃烧、性能和排放分析，这在压燃式发动机氢氧气体燃料研究中鲜有报道。在配备电子控制共轨直喷器的压燃式发动机的进气歧管中，以200毫升/分钟、400毫升/分钟、600毫升/分钟和800毫升/分钟的不同流速注入氢氧气体。峰值压力和最大热释放率随着氢氧气体浓度的增加而增加。在75%负荷下，对传统柴油燃烧和添加800毫升/分钟氢氧气体的情况进行了比较。一氧化碳和碳氢化合物排放分别减少了约37.5%和17.94%。一氧化碳和氮氧化物排放分别增加了9.37%和7.41%。在800毫升/分钟的氢氧气体流速下，记录到的烟雾排放极低，为0.01%至0.02%。因此，可以得出结论，氢氧气体在更好的燃烧和低排放方面具有可观的益处。然而，建议开展进一步研究，以便在实际汽车应用中使用这种添加剂。
