在柴油中添加20%的生物柴油,通过试验研究了掺混后的燃料对装甲车辆柴油机动力输出和排放的影响。结果表明:添加20%的生物柴油对各转速下最大输出扭矩影响不大,最大降幅小于2%;常用转速下(1400r/min)全负荷范围内降低碳烟的效果较好,可降低23%～100%;同时,HC排放量可降低11%～70%,CO排放量可降低33%;外特性工况下,在中、高转速时亦可降低碳烟排放22%～46%,但NOx排放有一定程度升高,部分工况下升高10%左右。 Adding 20% ​​biodiesel to diesel oil, the effect of blended fuel on power output and emissions of armored vehicle diesel engines was studied through experiments. The results showed that adding 20% ​​biodiesel had little effect on the maximum output torque at each speed and the maximum decrease was less than 2%. The effect of reducing soot was better at the full load range of 1400r / min, ~ 100%. At the same time, HC emissions can be reduced by 11% -70% and CO emissions by 33%. Under external conditions, soot emissions can be reduced by 22% -46% at medium and high speed, NOx emissions have increased to some extent, some conditions increased by about 10%.
