用 S195柴油机为试验样机,采取在进气过程中吸入少量氢气的方法,通过台架试验及分析,探讨了用氢作为涡流室柴油机副燃料的可能性及其实用价值。结果表明,吸入副燃料氢能显著改善燃烧,提高发动机性能,但保证性能良好的许用吸氢量具有一定限度,并存在最佳值;用氢作副燃料时,仅需适当增大涡流室通道截面比,而无需变动燃烧系统其它参数,即可获得较好效果。 S195 diesel engine was used as a prototype for the test, a small amount of hydrogen was sucked in during the intake process, and the possibility and practical value of using hydrogen as the secondary fuel for the vortex chamber diesel engine were discussed through bench tests and analyzes. The results show that hydrogen can significantly improve combustion and improve engine performance when sucked in by fuel, but there is a certain limit to ensure good performance of hydrogen absorption, and there is an optimal value. When hydrogen is used as the auxiliary fuel, only the vortex chamber Channel cross-section ratio, without changing the combustion system other parameters, you can get better results.
