在186F柴油机上进行了台架试验,测定了柴油机燃用十六烷值分别为46、50、55的甲醇/生物柴油的排放污染物及燃油消耗.考察了十六烷值对柴油机燃烧甲醇/生物柴油的排放污染物、经济性的影响.结果表明：在标定工况时,当甲醇/生物柴油的十六烷值为46、50、55时,NOx浓度分别为155×10-6、142×10-6、135×10-6；烟度分别为3.4、2.3、3.0；HC浓度分别为89×10-6、193×10-6、284×10-6；CO浓度分别为0.5%、0.8%、1.2%.随着甲醇/生物柴油十六烷值的增加,柴油机排放污染物中的NOx浓度和烟度降低,但HC和CO浓度增加.甲醇/生物柴油的十六烷值不能过高,否则会使柴油机排放污染物急剧增加.

The engine bench test was carried out on 186F diesel engine fuelled with methanol/biodiesel blend. The cetane number of the blend was 46, 50 and 55. The emission pollutants and fuel consumption of the engine fuelled with methanol/biodiesel was measured to investigate the effect of cetane number on pollutant and economy. Results show that, at rated condition, when the cetane number of methanol/biodiesel is 46, 50 and 55, the NOx concentration is 155×10-6, 142×10-6 and 135×10-6, smoke is 3.4, 2.3, 3.0, the HC concentration is 89×10-6, 193×10-6 and 284×10-6, and the CO concentration is 0.5%, 0.8% and 1.2%. With the increase of cetane number, the NOx concentration and smoke are reduced, but HC and CO concentrations are increased. Excessively high cetane number of methanol/biodiesel will significantly increase the pollutant concentration.
