• Biodiesel manufactured from canola oil was blended with the diesel and used as fuel in diesel vehicles. The project aims to test the emissions of diesel engines using blends of 100%, 80%, 60%, 40%, 20% biodiesel and 100% petroleum diesel, and characterise the particulate matter emissions, particularly health-related polycyclic aromatic hydrocarbons, and gaseous emissions. Both gaseous and particulate polycyclic aromatic hydrocarbons are collected separately by filter media and XAD sorbent tube. A real time dust monitor (Dustrak) was also used to monitoring the continuous dust emissions during the entire testing cycle. The common gaseous pollutants including NOx, HC, CO and CO<SUB>2</SUB> were analysed via on-line data analyser. The ECE(Euro 2) drive cycle was used for all the emission tests. Based on the results of four replicate tests of each blend, it was found that the particle concentration has been reduced up to 33% when the engine burns the 100% diesel, compare to burn the 100 petroleum diesel. A general trend of reduction of particle emission was found when the percentages of biodiesel in the fuel blends were increased. A correction factor of 6 was applied for real time particulate emissions of 100% biodiesel, and a correction factor of 3 was applied to emissions of 100% petroleum diesel. The discrepancy between Dustrak and gravimetric method was likely due to the fact that the Dustrak monitor was calibrated using a light brown coloured dust, but the diesel and biodiesel emissions were black. Limited reductions of about 10% were found at the emissions of NOx, HC and CO when burning biodiesel. In the case of CO<SUB>2</SUB>, the emissions of biodiesel and diesel were at similar levels. 18 EPA priority PAHs have been targeted, only 6 species of PAHs were detected in gaseous phase from the samples. A 50% reduction of total gaseous PAHs were observed when using 100% biodiesel rather than diesel. The overall levels of PAHs in particulate form were much lower than the gaseous PAHs. 9 individual PAHs were detected in particulate phase. Only a marginal reduction of 10% was found when burning biodiesel, instead of diesel. The individual particulate PAH levels in all blends did not display a clear trend of reduction. The information obtained is useful to understand the emissions and its environmental impacts of the biodiesel made from vegetable oil.
