Abstract
The present paper is a result of complex theoretical and experimental research made in time (at the Automotive Department of the Technical University of Cluj-Napoca) with the purpose of highlighting the quality of fuels in Romania. The physical and chemical properties are studied along with the soot deposits on the quartz liner and piston of a single cylinder research engine from AVL, and also the soot formation during an engine cycle.
