Gaseous Emissions - DieselNet

In engine emission standards, hydrocarbons are commonly regulated as either total hydrocarbons (THC), or as non-methane hydrocarbons (NMHC), the latter category excluding the simplest hydrocarbon methane (CH 4) due to its different atmospheric reactivity from longer chain hydrocarbons.
