The analysis of indicator diagram is performed with KDAM code application depending upon piston diameter, compression ratio, pressure gain, advance angle. The dynamic analyses have been performed for in-line, V-type and opposed internal-combustion engines.</p>Dynamic researchinternal combustion enginethe display diagramДинамическое исследованиедвигатель внутреннего сгоранияиндикаторная диаграмма
