Abstract
Przedstawione rozwiązanie umożliwia elektroniczne sterowanie ciśnieniem doładowania powietrza podczas pracy silnika w trybie dwupaliwowym, w sposób wykluczający powstawanie spalania stukowego. Korzystnym skutkiem proponowanego rozwiązania patentowanego jest całkowite uniezależnienie się od mechanicznego sterowania otwarciem zaworu upustowego spalin/układem zmiennej geometrii oraz dostosowywaniem ciśnienia w kolektorze dolotowym w zależności od obciążenia silnia oraz uzyskiwanego stopnia wymiany paliwa podstawowego na gazowe. Układ regulacji ciśnienia doładowania w silnikach dwupaliwowych, charakteryzuje się tym, że zawiera elektronicznie sterowany siłownik (1), który połączony jest z jarzmem zaworu wastegate/zmiennej geometrii zespołu (7) turbosprężarki (8). Siłownik połączony jest ze sterownikiem układu zasilania CNG. Sterownik układu gazowego otrzymuje sygnały od czujników ciśnienia powietrza (3) i temperatury powietrza (5) w kolektorze dolotowym silnika oraz od czujnika spalania stukowego (4).
