Dekarboniz\u00e1cia motora na LPG<\/h2>\n\n\n\n

Motor provozovan\u00fd na LPG netrp\u00ed na n\u011bkter\u00e9 z probl\u00e9m\u016f<\/strong>, kter\u00e9 tr\u00e1p\u00ed sou\u010dasn\u00e9 agreg\u00e1ty s p\u0159\u00edm\u00fdm vysokotlak\u00fdm vst\u0159ikov\u00e1n\u00edm. Jedn\u00edm z t\u011bch nejz\u00e1sadn\u011bj\u0161\u00edch je ni\u017e\u0161\u00ed tvorba karbonu<\/a>. Pro\u010d tomu tak je? LPG toti\u017e nem\u00e1 probl\u00e9m s nedokonal\u00fdm spalov\u00e1n\u00edm<\/strong>, nav\u00edc k tomu doch\u00e1z\u00ed p\u0159i vy\u0161\u0161\u00edch teplot\u00e1ch ne\u017e u benz\u00ednu.<\/p>\n\n\n\n

Jen\u017ee \u010dasto vstupuje do hry p\u0159\u00edvst\u0159ik benz\u00ednu<\/strong>, co\u017e je zp\u016fsob, jak ochr\u00e1nit sedla ventil\u016f i ventily samotn\u00e9. LPG je toti\u017e such\u00e9, nema\u017ee a ventily pak maj\u00ed tendence se opalovat, co\u017e je prov\u00e1zeno postupnou ztr\u00e1tou komprese<\/strong>. Proto se n\u011bkdy pou\u017e\u00edv\u00e1 p\u0159\u00edvst\u0159ik benz\u00ednu, kter\u00fd d\u00e1vkuje zhruba 1-3 litry tohoto paliva na sto kilometr\u016f<\/strong>. V\u011bt\u0161inou se jenom zkr\u00e1t\u00ed vst\u0159ikovac\u00ed \u010das t\u0159eba na 1 ms a aby neprob\u00edhal p\u0159\u00edvst\u0159ik po\u0159\u00e1d, spou\u0161t\u00ed se jenom nad ur\u010ditou hranici ot\u00e1\u010dek motoru. Jen\u017ee jakmile do procesu vstupuje benz\u00edn<\/strong>, hroz\u00ed i mo\u017enost tvorby karbonu<\/strong>, kter\u00e1 rozhodn\u011b nen\u00ed nere\u00e1ln\u00e1. Proto nen\u00ed od v\u011bci u takov\u00e9ho motoru dekarbonizaci jednou za \u010das prov\u00e9st<\/a>.

Dekarbonizace CNG motoru<\/h2>\n\n\n\n

Motor spaluj\u00edc\u00ed CNG funguje podobn\u011b jako motor na LPG<\/strong>. CNG v\u0161ak vy\u017eaduje trochu specifi\u010dt\u011bj\u0161\u00ed p\u0159\u00edstup<\/strong>, jeho mont\u00e1\u017e nen\u00ed jen tak. Pracuje se s o \u0159\u00e1d vy\u0161\u0161\u00edmi tlaky, co\u017e se prom\u00edt\u00e1 do ceny p\u0159estavby. \u010c\u00e1stka dosahuje obvykle zhruba dvojn\u00e1sobku p\u0159estavby na LPG. Dal\u0161\u00ed \u00fapravy vy\u017eaduje i motor, co\u017e je d\u016fvod, pro\u010d tov\u00e1rn\u00ed auta s pohonem na CNG<\/strong> m\u00edvaj\u00ed obvykle agreg\u00e1t vych\u00e1zej\u00edc\u00ed ze z\u00e1\u017eehov\u00e9ho<\/strong><\/a>, p\u0159esto lehce odli\u0161n\u00fd. M\u011bn\u00ed se hlava v\u00e1lce, va\u010dky, turbo, ale i katalyz\u00e1tor. Samostatnou kapitolou jsou p\u00edsty<\/strong>, kter\u00e9 automobilky \u010dasto vol\u00ed kovan\u00e9 nam\u00edsto obvykl\u00fdch lit\u00fdch. CNG je such\u00fd plyn, tak\u017ee je t\u0159eba tomu p\u0159izp\u016fsobit i ventily<\/strong>.<\/p>\n\n\n\n

Jestli m\u00e1 CNG n\u011bjakou v\u00fdhodu, pak jednozna\u010dn\u011b fakt, \u017ee karbon se v motoru nem\u00e1 z \u010deho vytv\u00e1\u0159et, plyn toti\u017e sho\u0159\u00ed prakticky dokonale<\/strong>, co\u017e je i d\u016fvodem, pro\u010d CNG neprodukuje zdaleka tolik emis\u00ed<\/strong>, jako pohon konven\u010dn\u00edmi palivy. Nen\u00ed tu ani p\u0159\u00edvst\u0159ik, tak\u017ee usazenin se tvo\u0159\u00ed minimum. Vod\u00edkov\u00e1 dekarbonizace<\/a> je zde sp\u00ed\u0161e prevenc\u00ed.<\/p>\n","protected":false},"excerpt":{"rendered":"
