Fuel effects on emissions from advanced diesel engines and vehicles

Report no. 2/05: To update understanding on emissions from road transport, CONCAWE is continuing to assess fuel effects on emissions from new engine/vehicle technologies as they approach the market. In this work, two advanced light-duty diesel vehicles and three heavy-duty diesel engines covering Euro 3 to Euro 5 technologies were tested on a wide range of fuels.

This report describes the results for the regulated emissions, HC, CO, NO_x and PM, as well as CO₂ and fuel consumption. The detailed particulates characterisation (size and number measurements) is covered in the companion CONCAWE report 1/05.
