Dziubenko A. Improvement of Vehicle's Fuel-Saving and Ecological Indexes on Basis of Ignition System Parameters Optimization

The thesis deals with the grounding and development of adaptive tuning method of ignition control system depending on vehicle's operation conditions. The theoretical generalization and the new task decision concerning the im-provement of vehicle's fuel-saving and ecological factors are presented in the given work. The task is settled by means of adaptive tuning of ignition control system for a particular mode of vehicle's operation on the basis of parameters optimization of ignition operation system according to the complex criterion. A new method for ignition system spark discharge parameters operation is developed. The theoretical and practical researches of ignition system spark discharge influence on engine's working process, according to the results of which the concept of multivariate ignition operation is offered, are developed. The mathematical model of management object that allows to obtain IS optimal parameters depending on the complex criterion which is determined by the vehicle's operation mode is developed. The IS adaptive tuning method for particular vehicle's traction mode is developed, and the expediency of its application is experimentally proved.
