Combustion Enhancement of Fuel Sprays by using Free Radicals Injection and Hydrogen Addition

为了研究1)热燃气喷射点火和2)加氢点火的点火和助燃效果，我们将这两种点火方法应用于悬浮在燃料蒸汽-空气混合物中的液体燃料喷雾。结果表明，本文所提出的点火方法，即使由于稀薄燃料条件、低温、低挥发分燃料等原因，在常规火花点火难以点燃的情况下，也能稳定地点燃和燃烧燃料蒸汽-空气混合物。

In order to investigate the ignition and combustion enhancement effects of 1) hot burnt gas jet ignition and 2) hydrogen addition, we applied these two ignition methods to liquid fuel sprays suspended in fuel vapor-air mixtures. As a result, it was found that the ignition methods suggested in the present work enable stable ignition and combustion of fuel vapor-air mixtures even if the mixtures are difficult to ignite by usual spark ignition due to lean fuel condition, low temperature, low volatility fuels, and so on.
