Waa maxay darajada naaftada loo isticmaalo kuleyliyaha baarkinka xilliga qaboobaha?

Chai Nuan, oo sidoo kale loo yaqaan kuleyliyaha baarkinka, wuxuu u isticmaalaa naaftada shidaal ahaan inuu ku kululeeyo hawada isagoo gubaya naaftada, isagoo gaarey ujeeddadii lagu afuufi lahaa hawo diiran iyo inuu qoyo qolka darawalka.Qaybaha ugu muhiimsan ee saliidda Chai Nuan waa alkanes, cycloalkanes, ama hydrocarbons caraf udgoon oo ka kooban 9 ilaa 18 atamka kaarboon.Haddaba waa maxay darajada naaftada loo isticmaalo kuleyliyaha baarkinka xilliga qaboobaha?
1. Marka la isticmaalayo kululeeyaha baarkinka xilliga qaboobaha, fiiro gaar ah waa in la siiyo doorashada ee saliidda engine iyo doorashada ee fasalka viscosity ku habboon.15W-40 waxaa loo isticmaali karaa laga bilaabo -9.5 darajo ilaa 50 darajo;
2. Isticmaalka kuleyliyaha baarkinka xilliga qaboobaha sidoo kale waxay u baahan tahay doorashada shidaalka naaftada, iyo darajo ku habboon (barafka qaboojinta) waa in la doortaa.No. 5 naaftada ayaa ku habboon in la isticmaalo marka heerkulku ka sarreeyo 8 ℃;Naaftada No. 0 waxay ku habboon tahay isticmaalka heerkulka u dhexeeya 8 ℃ ilaa 4 ℃;- No. 10 naaftada ayaa ku habboon in lagu isticmaalo heerkulka u dhexeeya 4 ℃ ilaa -5 ℃;- No. 20 naaftada ayaa ku habboon in lagu isticmaalo heerkulka u dhexeeya -5 ℃ ilaa -14 ℃;Si looga fogaado wax-ku-soo-ururinta jiilaalka oo saamayn kara isticmaalka, waxa lagu talinayaa in lagu daro shidaal naafto ah oo heerkiisu hooseeyo, sida -20 ama -35 shidaalka naaftada.Badeecooyinka saliidda ayaa dhamaantood lagu sifeeyaa habaynta saliida ceyriinka ah, iyadoo lagu darayo octane kala duwan iyo kiimiko lagu daro inta lagu jiro habka dhalaalidda.
3. Markaad isticmaasho kuleyliyaha baarkinka xilliga qaboobaha, waxaa muhiim ah in la rakibo kuleyliyaha jaakada biyaha si loo hagaajiyo waxqabadka bilowga qabow ee engine iyo awoodda culeyska, iyo sidoo kale si loo hagaajiyo qiiqa inta lagu jiro xaaladaha qabow.
