Данная статья освещает следующие задачи: расчёт объёма вогнутой части головки поршня, расчёт пол- ного объёма цилиндра при нахождении поршня в ВМТ (полный объём камеры сжатия), расчёт полного объёма цилиндра на начало такта сжатия и как результат расчёт степени и показателя политропы сжатия двухтактных ДВС. Точно рассчитанные вышеуказанные значения являются полезными для инженер- ных вычислений теплового баланса, теплового расчёта и расчёта безразборного метода диагностики ДВС

The present publication illuminate the tasks as follows: Piston top land inverted part volume calculation, cylinder total volume in TDC (compression chamber total volume) calculation, cylinder total volume at compression stroke beginning calculation and then as the result compression ratio & compression polytropic index calculation for two–stroke internal combustion engines (diesel engines). Precisely calculated mentioned above values are very useful for engineering calculations of the diesel engines heat–transfer, heat balance and undisassembled diagnostics
