ABSTRACT
The paper discusses the measurement methods of methane hydrocarbons, non-methane hydrocarbons and total hydrocarbons
set forth in the European emission regulations pertaining to M and N vehicle types and their engines. A model
for the determining of the concentration of the said hydrocarbons and mathematical formulas have been derived. The
concentration of the hydrocarbons determined as per the standards and the actual hydrocarbon concentration have been
compared. Based on the above, changes have been proposed in the methodology set forth in the regulations.
