The very short time available for the injection, combined with the poor penetration and mixing of the gas jet with the surrounding air, caused the serious problems with combustion initiation. One of the solutions to facilitate the ignition seems to be the use of a small ignition prechamber. The ignition takes place within the prechamber and the hot, chemically active combustion gases saturate the gaseous fuel jet that enters the main chamber where the mixing and combustion processes are continued. The results of the investigations aimed at obtaining an efficient and repetitive ignition of the gaseous fuel jet are presented. Various versions of the combustion chamber were investigated. The investigations were supported by the results of numerical calculations of the injection and mixing processes. We concluded that this type of combustion system has the potential to overcome the difficulties in achieving the repetitive ignition of the gaseous fuel jet"},{"@xml:lang":"sl","#text":"V prispevku so predstavljene analize sistema za dovajanje goriva pri motorjih z notranjem zgorevanjem in neposrednim vbrizgavanjem plinskega goriva. Kratki primerni časi za vbrizgavanje plinskega goriva ter slabo prodiranje goriva in mešanje le-tega z okoliškim zrakom pomenijo velike probleme pri pravilnem vžigu in nadzorovanem zgorevanju mešanice. Ena izmed rešitev za olajšanje vziga je uporaba manjše vzigalne predkomore. Vžig mešanice se tako začne že v predkomori, vroči in kemično dejavni zgorevalni plini pa nato pripomorejo k razbitju curka goriva v glavni zgorevalni komori, kjer poteka nadaljnje zgorevanje. Predstavljeni so rezultati raziskav vpliva oblike zgorevalnih komor pri uporabi neposrednega vbrizgavanja plinskega goriva na učinkovitost in ponovljivost vziga. Raziskave so podprte z rezultati numeričnih simulacij postopka vbrizgavanja in mešanja plinskega goriva. Prikazano je, da lahko s predlaganim sistemom obidemo tezave pri doseganju ponovljivega vžiga pri motorjih z neposrednim vbrizgavanjam plinskega goriva"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-KCCBQ6LS","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-KCCBQ6LS"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-KCCBQ6LS/a65adb2c-91e6-45f3-b988-949a883b62b8/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-KCCBQ6LS/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-KCCBQ6LS"}}}}
