本文就CH4-水蒸气以及正庚烷或正十二烷-水蒸气的催化重整反应对燃料与空气预混气的着大影响进行了几种不同工况的实验研究，并与纯燃料气（CH4气、正庚烷或正十二烷蒸气）和空气的预混气的着火进行对比．实验结果表明，在催化剂的作用下，烃类燃料气和水蒸气能在200～500℃的较低温度下进行重整反应，产生部分H2和CO。少量H2的存在大大降低了预混气的着火温度。若将这种催化剂用于柴油机汽缸壁，则可望使柴油机中的乳化油在汽缸壁上生成部分H2，因此可能在掺水量加大的条件下，仍然能实现汽缸中的正常燃烧，这不仅使乳化油在柴油机中的应用成为可能，而且将显著地改善柴油机的排放性能和节能效果．
In this paper, experimental studies on the large influence of CH4-water vapor and the catalytic reforming of n-heptane or n-dodecane-water vapor on the premixing of fuel and air were carried out and compared with pure fuel gas (CH4 gas, n-heptane or n-dodecane vapor) and air premixed gas. The experimental results show that under the action of catalyst, the hydrocarbon fuel gas and water vapor can undergo reforming reaction at lower temperature of 200-500 ℃ to produce partial H2 and CO. The presence of a small amount of H2 greatly reduces the ignition temperature of the premix gas. If this catalyst is used on the cylinder wall of a diesel engine, it is expected that the emulsified oil in the diesel engine will generate part of H2 on the cylinder wall, so that it is possible to achieve normal combustion in the cylinder even when the amount of water is increased, not only The use of emulsified oil in diesel engines is made possible, and the emission performance and energy saving of diesel engines will be significantly improved.
