SCANIA DT12 02 470 Euro 3 engineEmission measurements for VTI and COST 346

Anders Hedbom

Ulf Hammarström (Editor)

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 48A-2005, constitutes a documentation of exhaust emission measurments for one turbo compound engine, SCANIA DT12 02 470 Euro 3. In the COST 346 project AVL MTC has performed exhaust emission measurments on three engines.

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.

Figure 61 (Measurments have been made with the fan in fixed position but with a correction of the dynamometer simulating fan at max slip. In order to check the representativity of this correction three types of fuel consumption measurments, the first three types of dots, have been performed. Data points, black, describing the power demand of the fan is also included (from the manufacturer. The error in the correction, the dynamometer settings, is expressed of the difference in fuel consumption between yellow and blue data points. The difference between violet and and yellow data points expresses the extra fuel for the fan in fixed position.)
