摘要
在一台安装了油焦浆燃料供给系统的R180型柴油机上,进行了燃用油焦浆的试验。测量了发动机燃用油焦浆时的转速、转矩、燃料消耗量、排气温度、HC、CO、NOx和碳烟排放量等参数,并与原机燃用0号柴油进行了对比。试验结果表明,在1 200、1 600、1 800 r/min转速下,发动机燃用油焦浆时最大输出功率比燃用柴油时分别下降了约6.2%、19%和21%,排气温度平均升高了约5.3%、19.1%和34.2%。HC排放量在1 200 r/min时比柴油低,在1 600、1 800 r/min时两者比较接近;CO排放量在3种转速下和柴油相近;NOx排放量在3种转速下比柴油低;碳烟排放量在1 200 r/min时与柴油比较接近,在1 600、1 800 r/min时比柴油高。
The new petroleum coke slurry fuel system was adopted in a R180 diesel engine,and an investigation was carried out in the modified diesel engine with fuel of petroleum coke slurry.The speed,torque,specific fuel consumption,exhaust gas temperature,and HC,CO,NOx,smoke emission concentrations of the engine with fuel of petroleum coke slurry were measured respectively,and the comparison to the engine with fuel of No.0 diesel fuel was made.The results show that under the conditions of 1200,1600,1800r/min and burning petroleum coke slurry,engine maximum power is reduced by about 6.2%,19% and 21% respectively compared with burning diesel fuel,and the average exhaust gas temperature increases by about 5.3%,19.1% and 34.2% respectively;the HC emissions reduced at 1200r/min,and are similar to the diesel fuel at 1600,1800r/min;the CO emissions are close to diesel fuel;the NOx emissions decreased;the exhaust smoke density is similar to diesel fuel at 1200r/min,and is higher than diesel fuel at 1600,1800r/min.
