在不改变6300ZC柴油机结构和参数的基础上,开发了柴油机进气管预混甲醇裂解气的实验装置系统,研究了预混微量裂解气时柴油机的燃油经济性.研究结果表明,当柴油机进气预混甲醇裂解气的质量百分比为2.5%～5.0%时,各负荷下节油率可达5%～8%,综合油耗率与综合热效率均明显提高,且随着裂解气掺烧浓度的增加,油耗呈下降趋势.

In the premise of original structure and parameters of the 6300ZC diesel engine,a test equipment system of pre-mixed on-line methanol cracked gas at the intake manifold of the engine is developed.The fuel economy when cracked gas Was micro-premixed was studied.Results show that,when the quality percentage of the premixed methanol cracked gas is between 2.5% and 5.0%,saving rate of diesel consumption can reach 5% to 8% under different load of diesel engine,integrated rate of fuel consumption and thermal efficiency are obviously improved,and fuel consumption declines with the blended concentration of the cracked gas increases.
