Estimation of Relative Contributions of On-Road Spark-Ignition and Compression-Ignition Vehicles Fujita et al ][ ][ MTBE BC = MTBEsi BCci x VMTsi VMTci where [BC] = measured black carbon concentration in µg/m3 or [nC 10 -nC 15 ] from Tenax, [MTBE] = measured MTBE concentrations in µg/m3, BCci = assumed average CI emission rate of black carbon in grams/mile or heavy HC, and MTBEsi = assumed average SI emission rate of MTBE in grams/mile. The ratio of VMT,A = VMTsi VMTci = ][ ][ MTBE BC x BCci MTBEsi Ratio of the CI and SI source contribution estimates (sce) to NO can be estimated fromA and assumed average NO emission rates for CI and SI as follows.

[CO] is proportional toCOci xVMTci +COsi xVMTsi and [NO] is proportional toNOci xVMTci +NOsi xVMT si where [CO] = measured carbon monoxide concentration in µg/m3, [NO] = measured nitric oxide concentrations in µg/m3, COciand COsi = assumed average CI and SI emission rates of CO in grams/mile, and NOciand NOsi = assumed average CI and SI emission rates of NO in grams/mile.
