【 摘 要 】

The article presents selected results of experimental research of the compression ignition engine running on a new type of Fatty Acid Methyl Esters fuel and on a comparative standard fuel which is diesel oil. As a part of the test assessment, the waveforms and maximum values of pressure and temperature of the working medium in the combustion chamber under the same operating conditions of the engine supplied with the mentioned fuels were compared. Moreover, the phases of the combustion process were determined together with the exact determination of the share of the amount of heat released in each phase. New data is presented as analyzed and evaluated the tests results. Thus, it was established that the amount of heat released in the afterburning phase, for FAME type fuel, has reached higher values compared to standard fuel. Empirical studies were carried out in the Combustion Engines Laboratory at Institute of Vehicles, Warsaw University of Technology. For this purpose, the experimental stand equipped with a CI engine and AVL IndiSmart system that has an ability of registration of fast-changing parameters was used. An experimental setup has AVL Concerto software that was utilized for analysis.
