Emissions of Deuterated Tracers from Oil in Light and Heavy Duty Diesel Engine 2001-01-3531
Deuterated n-paraffins and polyaromatic compounds were added to a reference oil to elucidate its role on the emission of Soluble Organic Compound at diesel exhaust. This work carries on from previous investigations applied to fuel doping with deuterated compounds .
Both direct emissions and indirect effects, due to dilution with fuel components and combustion products are investigated. Furthermore the addition of deuterated compounds, is applied to calculate unburned percentage, to study the metabolism of lube oil component and can be applied to measure lube oil consumption.
In this paper the results obtained on a light duty and a heavy duty vehicle fuelled with a reference fuel are presented.
Particular attention was paid to total particulate and semi volatile phases.
