Serikova E. Improvement of diagnostics methods and prognostication of operating condition of automobile internal combustion engine

Thesis for competition of scientific degree of candidate of technical science on specialty 05.22.20 - operation and maintenance of vehicle. - Kharkiv National Automobile and Highway University, Kharkiv, 2011. The thesis is aimed at the increase of precision, efficiency, decrease of labour intensiveness of estimation methods of operating conditions of the piston-cylinder-unit and the crank gear of the internal combustion engine as well as prognostication of its residual life. In order to achieve the assigned task has been developed the adaptive method of indirect estimation of ICE operation conditions according to the parameters permitting the control in the process of engine's operation on the basis of artificial neural net application and fuzzy inference systems at data processing. At writing the thesis there has been developed an automated hardware-software complex for estimation of operating conditions and prognostication of ICE residual life. There has been produced its model sample as well as developed and adjusted the required software. There have also been developed structural schemas of the automated hardware-software complex for its further implementation as an on-board automobile device and a self-contained measuring complex.
