Verification of the mathematical model of an internal combustion engine using biogas fuel
An experimental study of the MeMZ-307 internal combustion engine on the use of biogas fuel for obtaining experimental indicator diagrams, determination of indicator and effective parameters of the engine is considered. Based on the analysis of the obtained data, the regularities of changing the adjusting parameters were revealed. Verification of the mathematical model of the combustion process in a biogas internal combustion engine has been performed, which makes it possible to calculate the power, economy and toxicity parameters of this engine by calculation, and also the equations for the variable combustion index and the duration of combustion have been experimentally tested in the range of changes in the indices biogas engine. Errors in the calculation of power, efficiency and toxicity with the help of the mathematical model obtained are within the limits allowed for the internal combustion engine.
