Plynov\u00e9 motory Scania OC13 a OC09 predstavuj\u00fa za\u010diatok produktovej ofenz\u00edvy spolo\u010dnosti, zameranej na alternat\u00edvne paliv\u00e1 pre nov\u00fa gener\u00e1ciu n\u00e1kladn\u00fdch vozidiel. OC13 je zalo\u017een\u00fd na osved\u010den\u00fdch 13-litrov\u00fdch motoroch Scania, ide v\u0161ak o novo vyvinut\u00fd motor, ktor\u00fd funguje na plyn na b\u00e1ze Ottovho cyklu, so zapa\u013eovac\u00edmi svie\u010dkami a \u00fapln\u00fdm spa\u013eovan\u00edm.

Plynov\u00e9 motory Scania s\u00fa zalo\u017een\u00e9 na stechiometrickom spa\u013eovan\u00ed, t.j. na \u00faplne inom spa\u013eovan\u00ed paliva aj kysl\u00edka. Spa\u013eovanie je zah\u00e1jen\u00e9 pomocou zapa\u013eovac\u00edch svie\u010dok, rovnako ako pri benz\u00ednov\u00fdch motoroch, a predmie\u0161anie paliva prebieha pri vstupe do valcov.<\/p>\n

D\u00f4kladne premyslen\u00e9 n\u00e1dr\u017ee<\/h3>\n

Typ rie\u0161enia n\u00e1dr\u017e\u00ed je v\u017edy d\u00f4le\u017eit\u00fdm aspektom plynov\u00fdch motorov. N\u00e1dr\u017ee pre LNG (skvapalnen\u00fd zemn\u00fd plyn) a CNG (stla\u010den\u00fd zemn\u00fd plyn) si m\u00f4\u017eete objedna\u0165 priamo od spolo\u010dnosti Scania. LNG v\u017edy poskytuje v\u00e4\u010d\u0161\u00ed dojazd, preto\u017ee ho je mo\u017en\u00e9 do vozidla natankova\u0165 v\u00fdrazne viac.<\/p>\n

\u201eAkon\u00e1hle je v motore, nez\u00e1le\u017e\u00ed na tom, ako bol plyn uskladnen\u00fd, ale existuj\u00fa zna\u010dn\u00e9 rozdiely v dojazde, ktor\u00fd s ka\u017ed\u00fdm rie\u0161en\u00edm dosiahnete,\u201c vysvet\u013euje Fritzson. \u201eS LNG prejdete s typick\u00fdm pr\u00edvesom na rovine okolo 1 000 kilometrov. Av\u0161ak rie\u0161enie s CNG, s ktor\u00fdm obvykle zvl\u00e1dnete 400 a\u017e 500 kilometrov, je tie\u017e pre mnoho z\u00e1kazn\u00edkov viac ako dosta\u010duj\u00face. Napr\u00edklad pre t\u00fdch, ktor\u00fdch \u00falohy zah\u0155\u0148aj\u00fa region\u00e1lnu prev\u00e1dzku s ka\u017edodenn\u00fdm n\u00e1vratom na z\u00e1klad\u0148u a doplnen\u00edm paliva.

Zvl\u00e1\u0161tnym bezpe\u010dnostn\u00fdm aspektom je, \u017ee in\u017einieri spolo\u010dnosti Scania oto\u010dili ventily n\u00e1dr\u017ee smerom dozadu proti smeru jazdy. Ide o zdanlivo jednoduch\u00fd, ale dobre premyslen\u00fd detail, ktor\u00fd zni\u017euje riziko po\u0161kodenia ventilov, napr. pri ich zasiahnut\u00ed vonkaj\u0161\u00edm n\u00e1razom.<\/p>\n

Pred\u013a\u017een\u00e9 servisn\u00e9 intervaly<\/h2>\n

Plynov\u00e9 motory, ktor\u00e9 pracuj\u00fa v Ottovom cykle (s predmie\u0161avan\u00edm paliva a zapa\u013eovac\u00edmi svie\u010dkami), maj\u00fa krat\u0161ie servisn\u00e9 intervaly ne\u017e dieselov\u00e9 motory. In\u017einieri spolo\u010dnosti Scania v\u0161ak zaviedli nieko\u013eko opatren\u00ed, s ktor\u00fdch pomocou dosiahli v\u00fdrazne dlh\u0161ie servisn\u00e9 intervaly. Dnes je to typicky \u017eivotnos\u0165 svie\u010dok, ktor\u00e1 ur\u010duje limity.<\/p>\n

\u201ePri be\u017enom pou\u017e\u00edvan\u00ed sme ako pre v\u00fdmenu zapa\u013eovac\u00edch svie\u010dok, tak pre v\u00fdmenu oleja stanovili interval 45 000 kilometrov,\u201c hovor\u00ed Fritzson. \u201eIde o v\u00fdrazn\u00e9 zlep\u0161enie oproti predch\u00e1dzaj\u00facim gener\u00e1ci\u00e1m plynov\u00fdch motorov, ktor\u00fdch norm\u00e1lny servisn\u00fd interval bol 30 000 kilometrov. Pre z\u00e1kazn\u00edka to znamen\u00e1 zn\u00ed\u017eenie n\u00e1kladov na \u00fadr\u017ebu a pred\u013a\u017eenie doby prev\u00e1dzkyschopnosti vozidla.\u201c<\/p>\n
