“…The model [5], based on the Grinevetsky -Masing method, is based on the idealization of the real process of heat release in diesel cylinders, where the heat supply process begins only when the piston is at top dead center at the end of the compression stroke. However, this method does not take into account at all the fact of the process of advancing the start of fuel supply to combustion chamber diesel engine using a nozzle and the ignition delay period.…”

The relevance of computer mathematical modeling, and processing of initial experimental data for follow-up assessment and analysis of the dynamics of heat release in diesel cylinders is growing every day. The main goal of our research consists in the development of a computer model defining the dynamics of heat release in diesel cylinders when it is running on fuels with different fractional composition, based on the application of the method of the Central Research Diesel Institute by analyzing the experimental data obtained in the form of an indicator diagram. The object of research is the method of processing the obtained experimental indicator diagrams. For this purpose, indicator diagrams of a 4CHN 11.0/12.5 diesel engine of the D-245.5S2 brand were obtained in the nominal mode. To implement the software module, a Java programming procedure was used, including the Java Development Kit where the writing, launching and compilation of Java code took place, the Java Runtime Environment, the Java runtime system, where the software distribution mechanism consisted of an autonomous Java virtual machine, standard Java libraries and tools for configuring it; and the Integrated Development Environment of an integrated development environment, where tools that helped launch, edit, and compile codes that provided thermal characteristics. As a result, an analysis of the available methods for determining the characteristics of the dynamics of diesel heat release was carried out, for the first time an algorithm was developed for performing calculations by the method of the Central Research Diesel Institute and a software module for calculating the characteristics of the dynamics of heat release in diesel cylinders when using fuels of various fractional composition based on experimentally obtained indicator diagrams. The use of the proposed technique and the corresponding software module for processing indicator diagrams, and subsequent analysis of the characteristics of the dynamics of heat release in diesel cylinders provides the required quality of the research results.

The urgency of mathematical simulation and electronic processing of obtained experimental data for estimating the working process increases by the day. The solution of real-world problems requires high-speed computer programs that enable us to reliably simulate complex processes occurring in engines and to simplify a considerable part of research effort. In connection with these considerations, the aim of our investigation is the improvement in the methods for estimating the nature of the working process of an internal combustion engine by applying CNIDI techniques for processing indicator diagrams by designing a hardware and software package. The package is able to present the obtained design data of heat-generation law values in a readable form of a digital model that enables us to produce their subsequent export into other software products for further research. The novelty of our work lies in developing a program for personal computers which is able to process experimental indicator diagram obtained in any form and by any technique for acquisition of heat-generation values. The main purposes of our investigation are the analysis of existing CNIDI techniques of processing indicator diagrams, the algorithm design of computer software operation and the verification of data obtained by programmed methods with design data. We found that applying the technique of processing experimental indicator diagrams is one of the methods most reliably describing the processes occurring in diesel cylinders. We analyzed the theoretical basics of a fuel combustion process by using experimental indicator diagrams, examined taking into account imprecision of source data, and validated ways of updating the data. We upgraded the computer program aimed at the methods of heat-generation data calculation under combustion according to specified diagrams. The use of introduced CNIDI techniques and the appropriate program of indicator diagram analysis provide the required quality of results in investigating the influence of various factors on fuel combustion process in an engine.
