5.3. Exhaust emissions
Fig. 6, shows the NOx emissions for bio-diesel A and B. NOx emissions using bio-diesel A shows a decreasing trend with increasing blend ratio, while emissions using bio-diesel B increases with increasing blend ratio, i.e. NOx emissions can increase or decrease depending on a number of factors such as bio-diesel type, engine type and test procedure used. Fig. 7, shows the percentage change in NOx emissions per blend ratio for the bio-diesels with the US EPA results. The US EPA reports a 10% increase in NOxemissions for B100 when compared to diesel, while bio-diesel A shows a 14% reduction and bio-diesel B shows a 17% increase.
