通过柴油发动机台架实验和行车实验，分析了不同工况下自制纳米WS2车用机油添加剂在柴油发动机中的应用效果。结果表明，在FC2000柴油发动机台架上应用时，纳米WS2车用机油添加剂在不同转速和不同负载下均能在一定程度上降低发动机油耗率，减少发动机尾气中NOx含量和颗粒物含量，并且当发动机转速为1700r／min，负载为70N?m时，节油率最高为9．95％，颗粒物减排率最高为49．3％，而当发动机处于低速、高速、低载和高载等工况时，NOx减排率较高，最高达到36％；在柴油机大客车上应用时，纳米WS2车用机油添加剂使其耗油量下降约14．4％，并能在一定程度上降低发动机的运行噪声，使发动机的有害气体（NOx）排放减少34．8％～51％。综合表明纳米WS2车用机油添加剂具有良好的节能减排效果。 Diesel engine bench test and road test were done to analyze the application effects of self-made nanometer WS2 motor oil additive on diesel engine under different working condition. Results show that,when applied on FC2000 diesel engine bench, nanometer WS2 motor oil additive can reduce engine＇ s fuel consumption to some extent under different rotate speeds or different loads, especially when the engine＇ s rotate speed is 1 700r/min and the load is 70N ? m, nanometer WS2 motor oil additive has the highest fuel saving ratio that is 9.95% and the highest PM emissions reduction ratio that is 49.3% ,and when the engine works under low speed, high speed, low load or high load, the NOx emissions reduction ratio nanometer WS2 motor oil additive is higher, best of which is 36% ,when applied on diesel engine bus, nanometer WS2 motor oil additive can decrease fuel consumption by about 14.4%, lower the engine＇ s working noise to some extent, and reduce the NOx emission by 34.8% - 51%. All above indicate that nanometer WS2 motor oil additive has excellent energy conservation ＆ emission reduction effects.
