Abstract
The effect of diesel fuel sulphur content and cetane number on regulated emissions was investigated in a Euro III diesel passenger car. Experimental results indicated that fuel sulphur level had a significant impact on all regulated emission, especially on PM. Testing fuels of different ignition qualities showed that HC and CO emissions of high cetane number fuels were significantly lower than emissions of a low cetane number fuel. We also observed a little decrease in NOx emissions with an increase in the cetane number.

In the whole NEDC test the lowest NOx emission was obtained for the fuel with cetane number (CN) = 63, for other fuels the NOx emission was by 3-4% higher and the recorded values were similar
In the Extra Urban Drive Cycle (EUDC) phase definitely the highest PM emission was obtained for fuel with the CN = 55, whereas for other fuels of both higher and lower cetane numbers the PM emission was by about 15% lower
