Abstract
POSTUPAK I UREDJAJ ZA ISPITIVANJE ZAPTIVKI I LOCIRANJE BILO KAKVOG PROPUŠTANJA U USISNO ISPUSNOM SISTEMU MOTORA SA UNUTRAŠNJIM SAGOREVANJEM SA UBRIZGAVANJEM GORIVA ZA MOTORNA VOZILA, pronalazak se odnosi na postupak i uredjaj za ispitivanje zaptivki i lociranje bilo kakvog propuštanja u usisno ispusnom sistemu (A) motora sa unutrašnjim sagorevanjem sa ubrizgavanjem goriva za motorna vozila. Ispitivanje se izvodi puštanjem komprimovanog vazduha u usisnu cev (C) motora pri prvoj regulisanoj vrednosti pritiska, detektovanjem vrednosti pritiska uzvodno u odnosu na usisnu cev, (C) ispušanjem komprimovanog vazduha iz usisne cevi (C) i detektovanjem ispusnog pritiska. Ispusni pritisak se uporedjuje sa napajanim pritiskom i, ako je prethodni ispod ranije odredjene vrednosti, pritisak napojnog vazduha se poveća, tako da se identifikuje mesto propuštanja. Uredjaj obuhvata izvor komprimovanog vazduha (4), ulaznu cev (1) za povezivanje izvora komprimovanog vazduha (4) sa usisnom cevi (C) ispusnog sistema (A) i izlaznu cev (2). Pored toga, uredjaj obuhvata i regulator pritiska (5), prvi indikator pritiska (7) koji je povezan sa ulaznom cevi (1) i drugi indikator pritiska (9) koji je povezan sa izlaznom cevi (2).
