FOX: an experimental and theoretical study of the chemical mechanisms linking fuel structures and toxic emissions from spark ignited engines

The chemical mechanisms linking fuel structures and toxic pollutants were studied experimentally to gain a better understanding of the formation of toxic emissions from spark ignition engines. The conclusion reached was that exhaust gas after-treatment and engine design offers better prospects than fuel formulation for emission con-trol.

Air pollution from road transport contributes to the greenhouse effect and can be detrimental to human health. The pollutants either result from fuel combustion within the engine or are initially present in the fuel. The FOX project aimed to provide experimental and theoretical information needed to understand the chemical link between fuel composition and pollutant emissions from a spark-fired engine. This information, combined with a knowledge of the physics of emission formation from motor vehicles, will contribute to a better understanding, and thus control of, the toxins released from any fuel engine system.
