Identifying the engine mathematical model is an important step in creation or optimization of the existing engines making it possible to reduce terms and costs at all the design stages. The available literature provides no information about the mathematical model setting in the Diesel-RK software package for the two-stroke high-speed carburetor engines with the crank-chamber purge. Geometry of such an engine is measured, the process of the Diesel-RK mathematical model setting is described, results of the mathematical model identification based on the experimental data are presented, and the obtained model accuracy is indicated. Problems identified in the identification process are also described, and conclusions are drawn on the need for improvements.
