✦ Synopsis

The authors studied deposits from combustion chambers of high-pressure engines supplied with standard fuel (SO) and ecological fuel of City-Diesel type. Chemical analysis, X-ray diffractograms, Mo Èssbauer absorption and additionally Raman wavenumber measurements were made. The wearing of some engine elements was examined by the pro®lometric method. By using ecological fuel, the deposits were shown to contain four to ®ve times less iron compounds than standard fuel supply. This accounts for a smaller attrition of the combustion chamber elements, and thus longer durability of the engine.
