Kravchenko S. Conversion of stationary engine GD100 to work on low-calorie gas fuels

The working process of the gas engine with pre- combustion chamber jet ignition and quality control capacity. Conversion GD100 stationary gas engine to run on low-calorie gas fuel by choosing its design and control parameters and operating parameters of the process. The fundamental position of the internal combustion engine theory. For the calculation of the thermodynamic parameters of the system used by the volume balance method prof. N.M. Glagoleva. To calculate the heat transfer gas in the cylinder wall used the method of Newton-Richman. The basis of a mathematical model describing the combustion process on the method of prof. I.I. Vibe. The estimated equation for determining the temperature condition of the combustion chamber parts approximation of the experimental data obtained by the method of least squares using the method of experimental design with 2 factorial positional orthogonal plan. Search rational values of the parameters of the engine was carried out by the study of the parameter space I.M. Sobol and R.B. Statnikov. All computational studies implemented in software MATLAB complex. Designed and implemented software complex mathematical models intracylinder engine processes with pre- combustion chamber jet ignition quality and power control, which allows to take into account the effect of the component composition and physico-chemical properties of the low-calorie gas fuels on the workflow and performance of the engine. The complex engineering activities to ensure the rated power GD100 Engine by using low calorie gas fuels. The rational design and adjustment of the engine settings GD100 that will provide qualitative ignition and combustion of the fuel-air mixture, high technical and economic performance of the engine by using the low-calorie gas fuels. For the first time offered dependence for determining the average engine combustion chamber wall temperature GD100, taking into account the effect of the surface area of the combustion chamber, as well as the parameters of the load mode. For the first time offered generalized empirical relationships that describe the dynamics and duration of combustion is very lean fuel gas with air. For the first time defined the qualitative and quantitative impact of the type of low-calorie gas fuel on the performance of the working process of the engine GD100.The results of the thesis put into practice development activities in SE "Zavod im. Malyshev" (Kharkov), and are also used during the teaching process and research at the department of internal combustion engines NTU "KhPI". Engine building.
