Overview
1. Collection of recent information and relevant knowledge on technical and enviromental effects of the use of high ethanol content gasolines in vehicles operated in the Czech Republic with regard to periodic vehicle technical inspections.
2. Determination of the influence of bioethanol concentration on standard measured vehicle emission parametres.
3. Search of a method of identification of the use of high ethanol content fuel in vehicles which are not approved for such fuelling.
4. Determination of the influence of the use of fuels with variable ethanol content on emission measurement results and on the parametres derived from the emission measurements carried out upon technical inspections.
