Exhaust Emissions from a Diesel Passenger Car Fuelled with a Diesel Fuel-Butanol Blend 2011-28-0017

The influence of oxygenated diesel fuel containing n-butanol on a passenger car exhaust emissions was tested over the NEDC transient cycle. The tests showed that a diesel fuel/butanol blend, containing 10% of n-butanol, caused a significant decrease in PM and smoke emissions, had no effect on NOx and CO₂ emissions and brought about higher CO and HC emissions. The most favorable result from the butanol application as diesel fuel component is that it produces desirable changes in PM/NOx trade-off.
