Recently, a proposal for the renewal of the legislation for the emissions of powered two-wheelers was published and will come into force from 2014 onwards if the legislation is approved by European Council and Parliament. One of the aims of the proposal is to reduce the possibilities of tampering of mopeds. The Dutch Ministry of Infrastructure and Environment needs more information on the effects of tampering on emissions of powered two-wheelers, to influence the European Commission in order to establish good legislation that reduces emissions in the real world. To evaluate the effects of tampering on emissions of mopeds, a measurement program was set up. In this program emission tests were performed on standard and tampered mopeds and the effects of tampering on the emissions and the fuel consumption were analysed. (Author/publisher)
