In terms of trade policy, intensive production of biofuels will help to curb agricultural overproduction and, thus, reduce The advantage of the Audi concept is that the engine can be run on subsidy levels. fuel with any concentration of up to 85  ethanol with no notice able diff erences in drivability or performance. Objectives for the development of the 2.0l TFSI ß exible fuel engine are To use an existing basic engine; 2.0l TFSI fl exible fuel engine designed to run on ethanol is based on the existing 2.0l TFSI engine with AVS and start stop technology. From the start, the customer does not notice any drawbacks in terms of driving comfort or driving pleasure. An engine running on bioethanol should start reliably at low ambient temperatures without any need for pre heating, which is usually the case with competitor products today. The favourable properties of the bioethanol will be utilised to optimise engine effi ciency at all operating points. 439 002 Learning objectives of this Self Study Programme are What does the term bioethanol mean What modifications does the 2.0l TFSI fl exible f
