【摘要】 通过发动机缸内分析法,对发动机的典型工况燃烧特性进行了试验研究,结果表明,天然气 柴油双燃料在低速时具有比燃烧纯柴油高的指示压力,最高爆发压力大于纯柴油,最大压力升高率也具有相同的规律,且双燃料的循环变动量大于柴油;而在中、高转速下,其具有与低速情况相反的规律.更多还原

【Abstract】 A experiment method about the engine’s combustion was conducted by the in-cylinder analysis of engine in some typical speed-lord conditions. And by this method, a result was achieved that the indicating pressure, the peak pressure and the max pressure increasing ratio of dual-fuel engine are higher than diesel engine’s in low speed conditions. But on the other hand, compare with diesel engine, the cycle variation of dual-fuel engine is more obviously. And it’s indicating pressure, peak pressure and max pressure increasing ratio are lower in middle and high speed conditions.更多还原
