Abstract

Przedmiotem zgłoszenia jest sposób i układ do oceny skuteczności działania filtra cząstek stałych bezinwazyjnie, który charakteryzuje się tym, że zawiera kanał pomiarowy (1) łączony z jednej strony z końcem układu wylotowego spalin badanego silnika, a z drugiej strony następuje swobodny wylot spalin z kanału pomiarowego (1). Kanał pomiarowy (1) strumienia spalin ma budowę liniową podzieloną na dolot (4), do którego kierowane są spaliny z rury wylotowej silnika, prosty odcinek, w którym dokonuje się pomiaru skuteczności działania filtra, wylot (5), i geometria kanału pomiarowego jest taka aby nastąpiła co najmniej czterokrotna zmiana kierunku przepływu strumienia spalin na całej długości kanału pomiarowego (1). Od wlotu strumienia spalin w prostym docinku kanału pomiarowego (1), jest wbudowane źródło promieniowania świetlnego (7), a z drugiej strony, w prostym odcinku jest wbudowany detektor (9) promieniowania świetlnego, w tej samej osi co źródło promieniowania światła. Układ zawiera co najmniej jeden trójosiowy czujnik przyspieszenia mierzący zwiększenia prędkości obrotowej silnika podczas pomiaru z uchwytem mocującym go do głowicy badanego silnika oraz moduł analizujący do analizy pomiarów zarejestrowanych przez detektor promieniowania świetlnego (9) i trójosiowy czujnik przyspieszenia, wyposażony w pamięć z zaimplementowanym algorytmem umożliwiającym wyliczenie czasu opóźnienia impulsu wzrostu zadymienia spalin w stosunku do impulsu wzrostu przyspieszenia kątowego silnika podczas pomiaru.The subject of the application is a method and system for non-invasively assessing the effectiveness of a particulate filter, which is characterized in that it comprises a measuring channel (1) connected on one side to the end of the exhaust system of the tested engine, and on the other side there is a free outlet of exhaust gases from the measuring channel (1). The measuring channel (1) of the exhaust stream has a linear structure divided into an inlet (4), to which exhaust gases from the exhaust pipe of the engine are directed, a straight section in which the effectiveness of the filter is measured, an outlet (5), and the geometry of the measuring channel is such that the direction of the exhaust stream flow changes at least four times over the entire length of the measuring channel (1). A light radiation source (7) is built into the inlet of the exhaust stream in the straight section of the measuring channel (1), and on the other side, a light radiation detector (9) is built into the straight section, in the same axis as the light radiation source. The system comprises at least one three-axis acceleration sensor measuring the increase in engine speed during measurement with a holder fastening it to the head of the tested engine and an analysis module for analyzing the measurements recorded by the light radiation detector (9) and the three-axis acceleration sensor, equipped with memory with an implemented algorithm enabling calculation of the delay time of the exhaust smoke increase pulse in relation to the engine angular acceleration increase pulse during measurement.
