    Abstract

    These measurements were part of the project “Increasing the energy efficiency of heavy-duty vehicles with technical and user specific measures”. The purpose of these measurements was to clarify the effect of lubrication oil on the fuel consumption of heavy-duty diesel engines. Measurements were done with 13 different oils at VTT Processes facilities in summer 2003. Oils were supplied by Fortum Oil & Gas Oy and HKL. Volvo bus engine mounted to engine dynamometer was used as a test engine. The measurement procedure included 8 different engine load points selected from the ESC –test cycle. The average specific fuel consumption was calculated over the load points and the results with this engine show that it is possible to gain some 2-2,5 % lower fuel consumption by selecting a right kind of lubrication oil.
