PM emissions results
Figure
7
shows that with increasing amount of biodiesel in the blend, NO
x
emissions present a noticeable increase. The CNG vehicle has lower NO
x
emissions
than the diesels.
The results for PM are given in Fig.
8
. PM emissions have decreased with increasing
amount of methyl ester in the blend. The most notable decrease was demonstrated
during the Dump process. The CNG vehicle did not emit PM emissions. Fossil fuel
combustion is the main source of global CO
2
levels. Figure

shows the CO
2
emissions
in g/s of the vehicle when operated under the driving cycle. It can be observed
