From page 68... ... Near-idle VOC emissions scaling allows us to decouple changes in the VOC composition of the exhaust from the variability in the absolute VOC EIs exerted by engine power and ambient temperature. The near-linear relationships observed in Figure A02-1 and the overall agreement between the ethene normalized EIs found here with that reported elsewhere, strongly suggests that the VOC composition is relatively insensitive to engine condition or fuel composition, at least over the limited range of engines studied and fuel compositions.
