Effects of Fuel Properties on Exhaust Emissions From Di Diesel Engines

Event: Autumn Conference
Effects of fuel properties on exhaust emissions from DI diesel engines were investigated. Test fuels, which have no interrelation among their properties, were prepared using some chemical solvents and compounds. Two engines to meet different emission regulations were selected to evaluate the difference of fuel effects on exhaust emissions. For the old model engine, it was certified quantitatively that most affective property on particulate emission was poly aromatics in the fuels and gaseous emissions were mainly affected by cetane number. However, poly aromatics and cetane number had little effect on exhaust emissions from new model engine.
