Adaptacyjna korekcja mapy paliwa i mapy zapłonu silnika wyczynowego

W artykule przedstawiono konstrukcje oraz sposób działania, programowalnego sterownika silnika spalinowego z zapłonem iskrowym, opracowanego na potrzeby tuningu samochodów sportowych. Opisano sposób sprzęgania komputera z systemem docelowym, algorytm jego pracy oraz struktury wykorzystywanych danych. Przedstawiono modyfikacje wprowadzone do ostatniej, czwartej wersji sterownika, dotyczące sposobu adaptacyjnego korygowania map: paliwa i zapłonu.

An engine of a race car is exposed to permanent modifications. As a result of realised modifications, the engine's parameters are still changing. A correct control of the supply of such engine needs many corrections of the single parameters and sometimes also of the algorithms used. The structure and functioning of the programmable controller for combustion engines with spark ignition, designed for the tanned sports cars there is presented in the paper. The method of connection of the computer with the target system has been presented in the first part. The second part has been dedicated to data structures and the working algorithms of the controller. The newest version of the computer presented in the paper seems to be a solution that meets all requirements concerning controllers used in race car engines. The enormous advantage of the solution is its universality, obtained thanks to the possibility of defining of main parameters within target system software, the most important being: the number and the layout of cylinders, construction of the pulse wheel and the structure of fuel and ignition systems. The user can chose different algorithms, concerning for instance the way of control of the injectors. The algorithms can be chosen according to the equipment of a given car as well as the user's preferences.
