柴油轿车燃用不同替代燃料的排放特性研究

Study on Emission Characteristic of Diesel Car Fueled with Different Alternative Fuels

对某款满足国Ⅳ排放要求的柴油轿车分别燃用国Ⅱ柴油、体积混合比分别为10%的国Ⅱ柴油-生物柴油(B10)和国Ⅱ柴油-天然气制油混合燃料(G10),以及沪Ⅳ柴油的排放特性进行了试验研究。结果表明,与国Ⅱ柴油比较,燃用B10的柴油轿车CO、PM和CO2排放降低,NOx和HC+NOx排放略有增加;燃用G10的柴油轿车CO、NOx、HC+NOx、PM和CO2排放降低;燃用沪Ⅳ柴油的柴油轿车CO、NOx、HC+NOx和PM排放降低,CO2排放与国Ⅱ柴油相当。

The emissions characteristics of a diesel car meeting the China national IV emission standard fueled separately with China II diesel, biodiesel with volume ratio of 10% （called B10）, which is the mixture of China II diesel and biodiesel, gas to liquid （GTL） blended in China II diesel （called G10）, and Shanghai IV diesel are tested and researched. The results show that compared with China II diesel, CO, PM and CO2 emissions of B10 fueled diesel car are reduced, whereas the NOx and HC＋NOx emissions increase slightly; CO, NO,, I-IC＋NOx, PM and CO2 emissions of G10 fueled diesel car are reduced; emissions of CO,NOx, HC ＋ NOx and PM of diesel car fueled by Shanghai IV diesel is reduced, and CO2 emission is comparable with that of China II diesel.
