Summary:

Over the past decade significant research and developmentactivities have been invested in alternative fuels in order toreduce our dependency on fossil fuel sources and reduce CO₂ andlocal emissions from traffic. One result of these R&D effortsis paraffinic diesel fuels, which can be used with existing vehiclefleets and infrastructures. Paraffinic diesels also have otherbenefits compared to conventional diesels, for example, a very highcetane number and the lack of sulfur and aromatic compounds. Thesecharacteristics are beneficial in terms of exhaust gas emissions,something which has been demonstrated in numerous studies.The objective of this study was to develop low-emissioncombustion technologies for paraffinic renewable diesel in acompression ignition engine, and to study the possible benefits ofoxygenated paraffinic diesel. Hydrotreated vegetable oil (HVO),which is a commercial example of paraffinic, renewable diesel, wasused with and without oxygenate in comparison with conventionaldiesel. Exhaust emissions were measured in three steady stateconditions. The adjusted engine parameters, such as inlet valveclosure and injection timing, injection pressure and amount ofexhaust gas recirculation (EGR) were optimized for HVO. The resultsdemonstrate that significant reductions of particulate matter(48-61%), polyaromatic hydrocarbon (75-87%) and NOx(31-54%) emissions can be achieved simultaneously by using HVO withadjusted engine parameters
