Abstract

The influence of high cetane number fuel blended with methanol on the combustion characteristics of diesel engine is studied. Fuels of high cetane number with different cetane number were compounded by FT diesel fuel and methanol. Bench tests were performed on 186F diesel engine. The cylinder pressure and heat release rate of different high cetane number fuels were measured. The change law of ignition delay period and the combustion duration of different methanol blending ratio under and loads were analyzed. The results show that under the rated condition, with the decrease of the mixed fuel cetane number, the maximum combustion pressure and peak value of heat release rate increase, and the corresponding crank angle is delayed. When the cetane number of the fuel reduces from 75 to 64 under constant load, the ignition delay period increases and the combustion duration reduces. The changes of the ignition delay period and combustion duration vary most obviously under 25% load, ranging from 2.8°CA to 6.1°CA, respectively. With the same high cetane number fuel, as the load increases, the ignition delay period shortens and the combustion duration increases.
