Petrol engine workflow model for researching unconventional engines

Abstract

The work lies with the study of petrol engines of an unconventional design with improved fuel and economic characteristics developed at the Automobile and Road Institute of Donetsk National Technical University for several decades. It describes the obtained mathematical model of the working process of a petrol piston engine to study the operation of engines. The authors used analytical methods of differential calculus to obtain a mathematical model. They solved the obtained equations using numerical methods and Simulink algorithms. Implementation required the development of a model that has sufficient speed to complete the tasks. The paper presents some modelling results, which makes it possible to judge the correctness of the obtained model. The implemented approach makes it possible to use this model in multi-domain modelling of the engine as a whole. The use of such a model opens up broad prospects for optimizing engine parameters, both its mechanical elements and the parameters of the working process. In addition, it becomes possible to develop and debug a control system for a petrol internal combustion engine using simulation in a Simulink environment.

Research of the efficiency of using the Miller cycle of an internal combustion engine

“…Анализ работ по данной теме [9][10][11] показал, что использование цикла Миллера с укороченным впуском в сочетании с увеличением степени сжатия и давления на впуске за счет использования наддува позволяет достичь высоких технико-экономических показателей.…”
