This research, published in the journal Separation and Purification Technology , shows that ozone can be used to remove not only SO x but also NO x from fossil fuel combustion exhaust streams. In this study, to improve absorption performance of SO 2 and NO 2 , we added ozone in exhaust gas. Osaka et al. Osaka et al.

Evaporative emissions are measured in a “SHED” (Sealed Housing for Evaporative Determination) test, which is a drive-in chamber built for the purpose of testing the fuel emissions of a vehicle that are not related to engine exhaust. It is also a tamper-proof solution.

NO x is a precursor for both ground level ozone and secondary PM 2.5 Manufacturers continue to optimize diesel emission controls, such as DOC, DPF and SCR, in order to promote uniform catalyst coating, improve NO x conversion efficiency, reduce back pressure on the engine, and reduce thermal mass.

The chemistry of a fuel impacts the emissions from an engine, with the most obvious example being unburned or partially burned fuel which is a major component of engine exhaust. Engine-out exhaust contains typically 1?3% via the unburned or partially burned fuel which is a major component of engine exhaust. —Hubbard et al.
