Hydrocarbons

Aromatics are molecules that contain at least one benzene ring. The fuel aromatic content will affect combustion and the formation of particulate and polycyclic aromatic hydrocarbon (PAH) emissions. The aromatics content of diesel influences flame temperature, and therefore, NOx emissions during combustion. PAH in the fuel affect the formation of particulates and PAH emissions from a diesel engine

The SGS WWFS diesel sampling results in the United Kingdom (UK) indicated good compliance with the 8% m/m regulatory limit.
