- An object of the paper is a novel method of effective heat release coefficient appointing during combustion process of the based on the real indicator diagram. The process quality of the heat release during process of combustion is evaluated by value of the effective heat release coefficient. Accepted assumptions at appointing effective coefficient of heat release refer to acceptable that thermodynamical parameters of the working charge according to points of the real indicator diagram and the computational diagram are such the same, the maximum pressure of real working cycle of the engine is equal to the pressure of the computational cycle, work of the working charge performed in period from point of closing of the inlet valve to point of the beginning of the exhaust process are for both considered working cycles equal, heat values of the carried to the real and computational cycle are such the same. The method of appointing of the self-ignition delay period is presented in the paper, using to this end intersection point of two graphs of temperature course of the working charge prepared for the first phase of combustion process. Other methods appointing characteristics is suggested in paper basing on the real indicator diagram. The graphic illustration of the preparing method of characteristics of the relative quantity of the heat release during combustion process is illustrated in paper.
