Lipinskiy M. Selection and Justification of Parameters of Average Power Gas Engine with Charging and Distributed Gas Feed

The thesis deals with problems of technical, economic and environmental performance of the gas engine equipped with a medium-power gas turbine system with separate charging system and gas supply by regulating the selection and optimization of parameters that affect the workflow engine workflow. The paper presents a constructive scheme of electromagnetic gas meters; the adjustment and design parameters of the distributed gas supply are grounded. The block diagram of the fuel control system with electronic control and the algorithm of forcing the control signal current "Peak & Hold" are offered. The advanced dual-zone model for calculation of the combustion process in the gas engine using dependencies for variable index of the nature and duration of the combustion process that allows improving the accuracy of calculations is improved. The experimental research of 6ГЧН 13/14 gas engine workflow is carried out. By using the method of multi-objective optimization of parameters there were developed and built the characteristic maps for the electronic control system. A comparison of efficient, environmental and economic performance of the 6ГЧН 13/14 engine with 6ГЧ 13/14 engine without charging is fulfilled. Key words: gas engine, gas turbine charging, distributed gas supply control system, combustion process, "poor combustion", natural gas, mathematical modeling.
