Increasing RME contents in Diesel fuels has an adverse impact for engine combustion chamber deposits formation as well on fuel injection system components. In the article discussed issues concerning with Cetane number determination of Diesel fuels about increased RME contents. Described troubles caused by difficulties in keeping stable engine running during making Cetane number determination by using of engine test bed. The influence of these issues for repeatability of obtained results has been also examined. Presented great own experience in the assessing the usefulness of engine test bed type Waukesha CFR for biofuels Cetane number determination. Comparison of repeatability obtained results Cetane numbers depending on the quantity of RME contained in Diesel fuel has been also performed. View of CFR test bed for Cetane number determination according to ASTM D 613 and picture engine's combustion chamber for the determination of Waukesha CFR Cetane number and piston assembly, view of injector hole pintle nozzle coking field of CFR engine for Cetane number determination, carbon deposit on piston crown and piston skirt, comparison of spraying stream fuel distribution through injector of CFR Waukesha test engine after biofuels determinations with standard distribution according to ASTM D 613, results of CN are presented in the paper.
