Muxuu injineerku u burburin doonaa haddii gaariga aan si sax ah loo kululayn xilliga qaboobaha? Waa maxay gaariga kulul ee ugu kulul?

Imaatinka jiilaalka, gawaarida kulul ayaa mar kale noqda mowduuc walaac laga qabo milkiilayaasha. In kasta oo tikniyoolajiyadda baabuurta casriga ah ay ka soo baxday carburetor ilaa duritaanka korantada, baahida loo qabo gawaarida kulul ayaa weli jira, laakiin muddo gaaban. Ujeedada gaariga kulul ayaa ah in loo oggolaado saliida iyo qaboojinta gudaha mashiinka si loo gaaro heerkulka ku habboon ee shaqada si loo hubiyo in qaybaha si buuxda loo duubo oo yareeyaan xirashada iyo yareeyaan xirashada.

Xilliga qaboobaha qabow, farqiga u dhexeeya qaybaha waa mid ballaaran marka matoorku bilaabmayo, taas oo fududahay in la xidho. Gaariga kulul wuxuu ka caawiyaa qaybaha kuleylka kuleylka oo ku guuleysta nadiifinta saxda ah ee ugu fiican. Tusaale ahaan, bey'ad laga jaray 10 digrii, codka matoorka ee gaariga bilaabay ayaa laga yaabaa inuu weynaado, laakiin heerkulku kor u kaco, dhawaqku si tartiib tartiib ah ayuu u soo noqon doonaa.

Marka, sidee loo kululeeyaa gaariga si macquul ah? Marka ugu horeysa, gaariga asalka ah ee deberoolka ah waa lama huraan, laakiin waqtiga gaarka ah waa in lagu hagaajiyaa iyadoo loo eegayo heerkulka. Marka heerkulku ka sarreeyo 0 darajo Celsius, gaariga asalka ah ee deberoolka asal ahaan looma baahna, waana laga eryi karaa. Marka heerkulku ku saabsan yahay laga jaro 5 digrii, waxaa lagu talinayaa in gaariga tabaabiga asalka ah 30 ilbiriqsi illaa 1 daqiiqo, ka dibna uu ku wado xawaare hoose ilaa shan daqiiqo. Marka heerkulka laga jaro 10 digrii iyo ka hooseeya, gaariga asalka ah ee dhul-bareedku waa 2 daqiiqo, ka dibna waxay gaabis tahay qiyaastii shan daqiiqo. Haddii heerkulku hooseeyo, waqtiga kuleylka waa in lagu dheereeyaa si ku habboon.

Waa in la ogaadaa in lagugula talinayo in gaariga dhul-galeenka asalka ah uu qaadanayo muddo aad u dheer, maxaa yeelay waxay u horseedi doontaa qashinka shidaalka iyo dardargelinta Karbon ee Karsoboon. Mid ka mid ah milkiiluhu wuxuu sababay caloosha inuu noqdo mid aad u wasakh ah maxaa yeelay gaariga wuu kululaaday muddo dheer, oo nalka qaladku wuu shiday markii gaariga cusubi uu wado 10,000 kiiloomitir. Sidaa darteed, gaariga kulul ee jiilaalka waa inuu ahaadaa mid dhexdhexaad ah, iyadoo loo eegayo heerkulka maxalliga ah si loo go'aamiyo dhererka gawaarida kulul, kuleylka guud ee guud ee 1-3 daqiiqo ayaa ku filan dadka badankood.

Gaariga kulul waa qeyb muhiim ah oo ka mid ah dayactirka baabuurta xilliga qaboobaha. Habka gawaarida kulul ee saxda ah ma ilaalin karo oo keliya mashiinka, laakiin sidoo kale hagaajinta amniga wadista gaariga. Mulkiileyaashu waa inay qaataan tillaabooyin baabuur oo ku habboon oo ku habboon iyadoo loo eegayo heerkulka dhabta ah iyo xaalada gaariga si loo hubiyo in gaariga uu ilaalin karo waxqabadka wanaagsan ee cimilada wanaagsan.
