汽油机掺烧代用燃料时的动力性研究

对汽油机掺烧代用为燃料，其动力性会受到影响的问题进行了理论分析，说明影响动力性能的几个参数，得到了一个可以反应混合燃料混合气热值变化情况的参数。在进行了汽油机少量掺氢燃烧的试验得出的结果表明，在低速时有功率损失，随着发动机转速的提高，功率损失减少，额定工况功率有所提高，与理论分析结果比较吻合。

Dynamic Performance of The Gasoline Engine Using a Blend Fuel of Gasoline and Alternative Fuel

Dynamic performance would be influenced when blend fuel (gasoline and one of alternative fuels) is used in a spark ignition engine. Some theoretical analysis was made on this subject. The author analyzed the factors that effect the dynamic performance, and a parameter was found at same time, which could explain the calorific value of the blend fuel-air mixture. Beside, some experiments were made on an engine fueled with gasoline and little hydrogen. The results show that there is power loss in lower speed. The loss becomes small and small as the speed is getting high, and the power output is some high than that of original in the specified condition at last. This was identical with the theoretical analysis.
