Development And Research of Gas Engine Multi-Communicated Model with Delay

Abstract

This article presents the simulation model of a gas engine designed to determine the optimal tuning parameters. The modern market requires the increase of engine power and a simultaneous decrease of fuel consumption [21; 19; 8]. The third important parameter is environmental friendliness [19; 8]. Thanks to computer modeling of the internal combustion engine, these parameters can be balanced [8; 1; 28]. The article presents the mathematical model of a gas-fueled engine, as well as the computer model implemented in the MATLab environment. The simulation results were compared with the parameters of a real engine after the bench test. The object of the study was the KAMAZ 82060 gas engine with the
capacity of 260 horsepower. The stand provided the version of the initial data. These are: effective power, fuel consumption per hour, temperature and pressure of the fresh charge at the inlet and the gas temperature in front of the turbine. The simulation result showed the simulation model deviations of no more than 12%. Thus, we can conclude that the developed computer model of the KAMAZ 82060 engine is quite accurate. In other words, we can conclude that this developed model of the KAMAZ 82060 engine can be used for other
studies, or for reconfiguring the engine by changing the design parameters of the selected engine in the computer model.
