Konke odinga ukukwazi mayelana motor oil

Amafutha enjini yethu ayiwoyela. Okusho ukuthi, into ebekwe phakathi kwezingxenye ezimbili ezihambayo yenza ifilimu evimbela ukuthintana kwazo. Ngale ndlela, ivumela ukunyakaza kwabo ngaphandle kokugqokwa ukungqubuzana. I amafutha emoto zenzelwe ukwenza lo msebenzi amazinga okushisa aphezulu nezingcindezi ngaphandle kokululaza.

Nokho, amafutha awanawo umsebenzi wokuvimbela ukuguga nokugqwala. Iphinde ihlanze futhi ifakwe efrijini izingcezu, ngaphezu kokusebenza njenge i-sealant phakathi kwama-piston nama-liners, esiza ukuvimbela ukuvuza kokucindezela. Ngakho-ke, kubalulekile ukusebenzisa uhlobo olufanele lwe-lubricant, ukugwema izinkinga ekusebenzeni kwenjini.

Kungani kudliwa uwoyela?

Kujwayelekile ukuthi kusetshenziswe uwoyela ngesikhathi sokusebenziseka kwenjini. Lokhu kungenxa yokuthi igcoba izingxenye ezibucayi kakhulu, njengama-piston noma ama-valve. Okusho ukuthi iyiphi ingxenye etholakala eduze kakhulu noma ngaphakathi kwegumbi elivuthayo. Ifilimu yokugcoba engenayo ishiswa ekushiseni uphethiloli, futhi uma lokhu kwenzeka ngokweqile, i- intuthu yemoto yethu izoba nombala oluhlaza okwesibhakabhaka.

Izimoto zivame ukudla amafutha amaningi uma sebekhulile. Ngokuhamba kwesikhathi, ukucaciswa kwezingxenye kuba kukhulu okubangela izindleko ezengeziwe zokugcoba. Ibuye idliwe njalo amafutha amaningi uma injini ivuselelwa. Njengoba injini iphenduka ngokushesha, iba nokuqhuma okwengeziwe, okubangela ukushiswa kwamafutha kuleyo naleyo.

Kungani amafutha eba mnyama?

Umbala omnyama wamafutha ayibonisi ukuthi isesimweni esibi. Ukuhlanza izitho zangaphakathi zenjini kungomunye wemisebenzi ye-lubricant. Enqubweni yokuvutha kwenjini, umsizi, i-lacquer nokunye ukungcola. Amafutha aqoqa lokhu kungcola futhi ashintshe umbala. Nokho, inokubekezela okukhulu. Uma ingashintshiwe ngesikhathi esiboniswe umenzi, amafutha azolahlekelwa ukusebenza kahle ngenxa yokungcola okuningi ekumisweni. Kufanele futhi kukhunjulwe ukuthi izinjini zikadizili zenza uwoyela ube mnyama ngaphezu kwezinjini zikaphethroli.

Zisho ukuthini izinombolo zikawoyela?

Kungenzeka ukuthi ubonile ukuthi emafutheni emoto kuhlala kukhona a ikhodi, njenge: 5W40, 10W40, 5W30… Lezi zinombolo zibhekisela ku i-viscosity yamafutha ashisayo nabandayo. Uma inani liphakeme, amafutha e-viscous kakhulu, futhi inombolo ephansi, izoba noketshezi oluningi.

El inombolo yokuqala Kubonisa i-viscosity yamafutha uma kubanda. Ngakho-ke, uma sizoyiqala imoto emazingeni okushisa aphansi kakhulu, kuzoba ngcono ukuba nenombolo encane efana ne-5W. I inombolo yesibili inquma i-viscosity yamafutha ku-100º, cishe izinga lokushisa elivame ukusebenza kulo. I-W ehlukanisa zombili izibalo isho 'ubusika' ngesiNgisi futhi ibhekisela kweyokuqala kuphela.

I-viscosity efanelekile kakhulu leyo enconywe umenzi wemoto. Ngokuya ngomklamo wenjini kanye nezindawo ezivunyelwe izingxenye zayo, izodinga uhlobo olulodwa lwamafutha noma olunye. Nakuba ingahluka kancane kuye ngezimo zezulu kanye nokusetshenziswa okuzonikezwa yona. Futhi ama-viscosity angaxutshwa esimweni esiphuthumayo, njengokugcwalisa okuvamile lapho izinga likawoyela liphansi. Kodwa i-viscosity ewumphumela ngeke ibe yinto enhle.

Amaminerali noma uwoyela we-synthetic motor

Amafutha amaminerali nawokwenziwa ahluke ngokuyinhloko ku indlela yokuthola. Amaminerali atholakala ku-distillation kawoyela ongahluziwe, kuyilapho ama-synthetics enziwa ngezinye izinqubo zamakhemikhali ezenziwa efektri, nakuba zisebenzisa izingxenye ezithathwe ku-petroleum. Ngokuqondene neyakhe izakhiwo:

• Ukuqina: Njengomthetho ojwayelekile, amafutha okwenziwa ahlala isikhathi eside kunamafutha amaminerali. Cishe kabili.
• Intengo: amafutha omsuka wamaminerali ashibhile kunamafutha okwenziwa ngoba inqubo yokuyithola ilula.
• Ukuhambisana Kwenjini: Amafutha amaminerali avame ukusetshenziswa ezinjinini ezindala (kuze kufike ekuqaleni kwawo-90). Ama-synthetics asetshenziswa ezinjini zesimanje.
• Ukuhlukahluka kokusetshenziswa: amafutha okwenziwa agcina izakhiwo zawo ebangeni lokushisa eliphakeme. Okusho ukuthi, basebenza kangcono kokubili kushisa noma kubanda. Amaminerali anezinhlobonhlobo zamazinga okushisa aphansi afanele ukusebenza kwawo.

Wonke amafutha asemakethe (injini kaphethiloli noma idizili, amaminerali noma okokwenziwa) zingaxutshwa nomunye. I-drawback kuphela ukuthi ukwenza kanjalo kwehlisa ikhwalithi yabangcono kokubili. Ngakho-ke kufanele uyishintshe uma kufika isikhathi saleyo ehlala isikhathi eside.

Ukushintsha nini uwoyela

Isikhathi sokushintsha uwoyela kunqunywe futhi ngumenzi. Inikezwa ngokusekelwe kumapharamitha amabili: imayela kanye nesikhathi sokusetshenziswa. Ekushayeleni kwasemadolobheni, ngokuqala nokuma njalo, kungase kube kuhle ukunciphisa isikhathi phakathi kwezinguquko zamafutha.

Kunoma yikuphi, kuwumkhuba omuhle ukubonisana ku-workshop ukuthi yiziphi izinhlobo zamafutha esingazisebenzisa. Uma isikhathi esiphakathi kokushintsha kwamafutha siside, kufanele futhi simiselele isihlungi (isithombe ngenhla). Uma kungenjalo, singashintsha isihlungi njalo ngezinguquko ezimbili zikawoyela. Nakuba kulezi zimo kuyanconywa futhi landela imiyalelo yomkhiqizo.
