Claims (1)

Способ получения индикаторной диаграммы поршневого двигателя косвенным путем как функции угла поворота коленчатого вала, включающий запись и выделение давления газов в цилиндре как удельных сил на стержне шатуна, отличающийся тем, что вместо датчика положения коленчатого вала в измерительную схему дополнительно введен блок анализа положения верхней мертвой точки, выход которого соединен со входом в компьютер с целью определения положения верхней мертвой точки и последующего использования ее в качестве аргумента в тригонометрических функциях выделения давления газов в цилиндре при анализе сил в кривошипно-шатунном механизме как функции угла поворота коленчатого вала.A method of obtaining an indicator diagram of a piston engine in an indirect way as a function of the angle of rotation of the crankshaft, including recording and isolating the gas pressure in the cylinder as specific forces on the connecting rod rod, characterized in that instead of the crankshaft position sensor, a top dead center analysis unit is additionally introduced into the measuring circuit whose output is connected to the input to the computer in order to determine the position of the top dead center and then use it as an argument in trigonometrically functions evolution of gas pressure in the cylinder in the analysis of forces in the crank mechanism as a function of crank angle.
