【 摘 要 】

The article presents results of tests regarding the injection and fuel combustion process in PERKINS 11004C-44 engine working in line with external speed characteristics and fuelled with natural and plant fuels and the impact on the indexes of non-repeatability of fuel pressure and combustion processes. The analysis of the test results allowed for identifying the differences in the injection and combustion processes in the engine fuelled with the different fuels. The use of fuels with different physical & chemical properties in diesel engines requires high precision measurements of the diagnostic in order to establish the existing differences in the processes of injection and combustion engines running on these fuels. The comparative analysis points indicate similarity in character of changes as regards the non-repeatability indexes of the fast-changing magnitudes for engine powered mineral fuels and plant. Compliance with more and more stringent standards regarding toxic contents in exhaust gases forces modern users of diesel, selfignition engines to have quick and accurate methods for assessing the technical condition of the engine, in particular the combustion process and the technical condition of the injection unit based on indexes of non-repeatability of maximum fuel and combustion pressures.
