3 Preface VTI has on commission of VINNOVA and the Swedish Road Administration (SRA) participated in COST 346: Emissions and fuel consumption from heavy duty vehicles. In this commission VTI has engaged AVL MTC Motortestcenter AB. The research efforts at AVL MTC have been executed by Anders Hedbom. This report, VTI notat 52A-25, constitutes a documentation of exhaust emission measurements for one engine, SCANIA DC12 1 Euro 3. In the COST 346 project AVL MTC has performed exhaust emission measurements on three engines in total. Project leader at VTI has been Ulf Hammarström. Contact persons: Carl Naumburg at VINNOVA and Håkan Johansson at SRA. Gunilla Sjöberg, VTI, has performed the final revision of this document. Linköping, December 25 Ulf Hammarström VTI notat 52A-25
