The central position is comparatively favorable with respect to the activity in the cylinder, as well as from the technological point of view. Measurements of the flame front speed in a cylinder established that the flame does not spread symetrically with respect to the composition of the exhaust gas. Further, it was established that the change of the spark plug's position, or the addition of a second spark plug, results in a more favorable composition of the exhaust gasses without changing the characteristics of the engine. A duble outlet thyristor ignition system of high voltage with the possibility of adjusting the preignition during engine operation, was used. The results show that the central position of the spark plug is a low-priced solution which nowadays is not always acceptable"},{"@xml:lang":"sl","#text":"Svečka pri majhnih dvotaktnih motorjih leži pogosto v sredini glave motorja. Sredinska postavitev svečke je razmeroma ugodna glede na dogajanja v valju in na tehnološke rešitve. Meritve širjenja čela plamena v valju pa kažejo, da se plamen ne širi simetrično glede na lego svečke, ampak v odvisnosti od temperature in tokovnih razmer v valju. Preskusi so pokazali, da sredinska lega svečke, ni vedno upravičena, še posebej z vidika sestave izpušnih plinov. Nadalje se je pokazalo, da se s spremembo lege ene svečke ali pa z dodajanjem druge svečke lahko doseže ugodnejša sestava plinov v izpuhu, ne da bi se pri tem spremenile druge značilnosti motorja. Pri preskusih je bil uporabljen tiristorski vžigalni sistem z dvojnim izhodom visoke napetosti z možnostjo brezstopenjskega spreminjanja predvžiga med obratovanjem motorja. Rezultati meritev kažejo, da je središčna lega svečke le cenovno ugodna rešitev, kar pa v današnjem času ni več vedno sprejemljivo"}],"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-OPFDXOR1","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-OPFDXOR1"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-OPFDXOR1/62cf1e82-c321-471d-8b4e-9a638c8f36a9/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-OPFDXOR1/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-OPFDXOR1"}}}}
