Volatile hydrocarbons in exhaust from alkylate-based petrol
Artikel i vetenskaplig tidskrift, 1993

The non-methane hydrocarbon composition was studied for emissions from new alkylate-based fuels marketed for applications of special concern to human health and the environment. Proportions of 27 selected C2-C8 hydrocarbons were determined in moped exhaust for an alkylate-based fuel and a conventional reformate-based fuel. Samples were taken on an adsorbent cartridge behind the moped during driving, and were analyzed by thermal desorption and gas chromatography on an alumina column. About 90% of the hydrocarbons emitted from the two-stroke moped engine were unburnt fuel hydrocarbons.
