本文就解放牌汽车CA15发动机在燃用甲醇、汽油混合燃料M15(汽油85%、甲醇及助燃剂15%)与燃用纯汽油两种情况下,对排放性能所作的对比试验结果,作了全面而扼要的论述。试验结果表明,燃用M15与燃用汽油相比,发动机的经济性、动力性都有所改善,排放中的主要有害成分下降较多。全负荷时CO降低38%,HC降低39%;部分负荷时NO_x降低40%。排放法规外的特殊排放物质如甲醇、甲醛等有所增加,但就其绝对值而言仍是较低的。
In this paper, Jiefangbei CA15 engine in the combustion of methanol, gasoline mixed fuel M15 (85% gasoline, methanol and combustion improver 15%) and the case of pure gasoline burning two cases, the emission performance of the comparative test results, made a comprehensive The brief discussion. The test results show that, compared with the combustion of gasoline, the economy of M15 is improved, the power of the engine is improved, and the emission of the main harmful components declines more. At full load, CO is reduced by 38% and HC is reduced by 39%. NO_x is reduced by 40% at part load. Specific emissions of substances other than emission legislation such as methanol, formaldehyde and so on have increased, but in terms of their absolute value is still low.
