Abstract
When switching from regular diesel fuel (sulfur free) to paraffinic
hydrotreated vegetable oil (HVO), the changes in fuel chemistry and
physical properties will affect emission characteristics in a very
positive way. The effects also depend on the technology,
after-treatment and sophistication of the engine. To determine the real
effects in the case of city buses, 17 typical buses, representing
emission classes from Euro II to EEV, were measured with HVO, regular
diesel and several blended fuels. The average reduction was 10% for
nitrogen oxides (NOx) and 30% for particulate matter (PM).
Also some engine tests were performed to demonstrate the potential for
additional performance benefits when fuel injection timing was optimized
for HVO.
