The article presents an algorithm of diagnosing damages to the exhaust valve of the combustion engine. The process of obtaining a symptom as a difference spectrum takes into account time selection, which allows to reduce significantly the calculations necessary to obtain a measure of malfunction. As a result, we obtain a simple measure not requiring special conditions of object work and insensitive to simultaneously occurring valve clearance which is inappropriately set. Thus, we obtain a measure easy to use in diagnostics in real time.

W artykule przedstawiono algorytm diagnozowania uszkodzeń zaworu wylotowego silnika spalinowego. Proces pozyskania symptomu w postaci widma różnicowego uwzględnia selekcję czasową, co pozwala znacznie ograniczyć obliczenia niezbędne do otrzymania miary niesprawności. W efekcie otrzymujemy miarę prostą, niewrażliwą na równolegle występujący nieprawidłowo ustawiony luz zaworowy i nie wymagającą specjalnych warunków pracy obiektu. Tym samym otrzymujemy miarę łatwą do wykorzystania w diagnostyce w czasie rzeczywistym.
