- The research was divided into two stages. The first stage of work was to perform empirical research using the Perkins engine. The test stand was equipped with an exhaust gas composition analyzer, a pressure sensor enabling measurement of pressure in the engine cylinder and a crankshaft position sensor. This stage of research was realized for diesel and UCOME fuel. The second stage was a simulation test. The Zeldowicz model of thermal NO formation in compression ignition engines was used for calculations. Theoretical methods were compared with the results obtained in empirical tests. It was found that the most similar results of tests when powering the engine with UCOME fuel were obtained thanks to the GRI-MECH 3.0 (GM3) method. On the basis of this method, coefficients of the reaction rate of NO formation in an internal combustion engine, which is powered by the higher generation alternative fuel (Sikora et al. (S) method) were developed. For the calculation tests the values of the experimentally determined pressures were used. The proposed method can be used in simulation tests of a diesel engine running on FAME fuels with similar physical and chemical properties as the UCOME fuel. This will significantly reduce the costs of such tests, as some empirical tests can be eliminated by the conclusions of the simulation tests.
