Summary:

This paper provides information on measurements and measurement techniques for particulate and unburnt hydrocarbon emissions from diesel engines.A dilution mini-tunnel was used to characterize the effects of the dilution ratio and sample temperature on the total particulate mass and soluble organic fraction(SOF) constituents. Increasing the sample temperature resulted in changes in the polynuclear aromatic hydrocarbon(PAH) constituents in SOF. The SOF was isolated by column chromatography, and the PAH fraction was determined by high performance liquid chromatography(HPLC). Column chromatography with silicagel, an octadecylsilan-bonded column, and keeping at high temperatures improved the analytical efficiency of HPLC. The gaseous hydrocarbon in raw exhaust was analysed by GC with FID. The temperature of the sample glass syringe affected measurements of high boiling point hydrocarbon constituents
