Kungenzeka yini ukugcwalisa uwoyela 5w40 esikhundleni 5w30?
Okuqukethwe
Omunye wemibuzo ethandwa kakhulu phakathi kwabashayeli ukushintshwa kwamafutha ezimoto. Ezithangamini eziningi, ungathola imibuzo ejwayelekile njengokuthi: "kungenzeka yini ukugcwalisa uwoyela we-5w40 esikhundleni sika-5w30?", "Ingabe kungenzeka ukuxuba amanzi amaminerali nama-synthetics noma ama-semi-synthetics?" njalo njalo. Sesivele siphendule eminingi yale mibuzo kuwebhusayithi yethu i-Vodi.su, futhi sahlaziya ngokuningiliziwe izici zokumaka i-SAE yamafutha emoto. Kulesi sihloko sizozama ukuthola ukuthi ukusetshenziswa 5w40 esikhundleni 5w30 kuvunyelwe.
Amafutha enjini 5w40 no-5w30: umehluko nezici
Ifomethi ethi YwX, lapho u-“y” kanye “x” kuyizinombolo ezithile, kufanele ikhonjiswe emathini enjini noma kawoyela wokuhambisa. Lena inkomba ye-viscosity ye-SAE (Society of Automobile Engineers). Izinhlamvu ezikuyo zinencazelo elandelayo:
- uhlamvu lwesiLatini u-W luyisifinyezo sesiNgisi sasebusika - ubusika, okungukuthi, uphethiloli nezinto zokugcoba, lapho sibona khona le ncwadi, zingasebenza emazingeni okushisa angaphansi kwe-zero;
- idijithi yokuqala - kuzo zombili izimo "5" - ikhombisa ubuncane bokushisa lapho uwoyela uhlinzeka khona ngokuncibilika kwe-crankshaft futhi ungampontshwa ngohlelo lukaphethiloli ngaphandle kokushisisa okwengeziwe, kuphethiloli ongu-5W0 nezinto zokugcoba lesi sibalo sisuka ku--35 ° C ( ukudonsa) kanye -25 °C (ukujika);
- amadijithi okugcina (ama-40 nama-30) akhombisa ubuncane bezinga lokushisa nokugcinwa koketshezi oluningi.
Ngakho-ke, njengoba akunzima ukuqagela, ngokusho kwesigaba se-SAE, amafutha enjini aseduze nomunye nomunye futhi umehluko phakathi kwabo uncane. Siklelisa ukucaca ngendlela yohlu:
- 5w30 - igcina i-viscosity emazingeni okushisa aphakathi nendawo ebangeni ukusuka ku-minus 25 kuya ku-25 degrees;
- 5w40 - yakhelwe uhla olubanzi ukusuka ku-minus 25 kuya ku-35-40 degrees.
Qaphela ukuthi umkhawulo wokushisa ongaphezulu awubalulekile njengalowo ophansi, njengoba izinga lokushisa likawoyela osebenzayo enjini likhuphukela kuma-degree angu-150 nangaphezulu. Okungukuthi, uma unamafutha e-Mannol, Castrol noma e-Mobil 5w30 egcwele, lokhu akusho ukuthi ngesikhathi sohambo oluya eSochi, lapho izinga lokushisa likhuphuka ngaphezu kwama-30-40 degrees ehlobo, kufanele lishintshwe ngokushesha. Uma uhlala njalo esimweni sezulu esishisayo, udinga ukukhetha amafutha nama-lubricant anenombolo yesibili ephakeme.
Futhi omunye umehluko obalulekile phakathi kwalezi zinhlobo ezimbili zokugcoba umehluko we-viscosity. Ukwakheka kwe-5w40 kubukeka kakhulu. Ngakho-ke, ukuqala imoto emazingeni okushisa aphansi kulula kakhulu uma uwoyela we-viscous ugcwele - kulokhu, 5w30.
Ngakho-ke kungenzeka yini ukuthulula i-5w30 esikhundleni se-5w40?
Njenganoma yimuphi omunye umbuzo mayelana nokusebenza kwezimoto, kunezimpendulo eziningi futhi "kodwa" ngaphezulu. Isibonelo, uma kunesimo esibucayi, ukuxuba izinhlobo ezahlukene zamafutha kanye nezinto zokugcoba kuyamukeleka, kodwa ngemva kwalokho kungase kudingeke ukuthi uyikhiphe ngokuphelele injini. Ngakho-ke, ukuze unikeze izincomo zochwepheshe kakhulu, kuyadingeka ukuhlaziya isimo sobuchwepheshe bemoto, imiyalelo yomkhiqizi, nezimo zokusebenza.
Sibala izimo lapho ukushintshela kuwoyela nge-viscosity index ephezulu akunakwenzeka kuphela, kodwa kwesinye isikhathi kuyadingeka:
- ngesikhathi sokusebenza isikhathi eside kwemoto ezindaweni ezinesimo sezulu esishisayo;
- ngokugijima ku-odometer yamakhilomitha angaphezu kwezinkulungwane eziyi-100;
- ngokuncipha kokucindezela enjinini;
- ngemuva kokulungiswa kwenjini;
- njengendlela yokuguquguquka ukuze isetshenziswe isikhathi esifushane
Ngempela, ngemva kokudlula amakhilomitha ayizinkulungwane eziyi-100, izikhala phakathi kwama-piston nezindonga ze-cylinder zanda. Ngenxa yalokhu, kukhona ukugcwala kwe-lubricant nophethiloli, ukwehla kwamandla nokucindezelwa. Amafutha e-viscous amaningi kanye nezinto zokugcoba zakha ifilimu yokuqina okukhulayo ezindongeni ukuze kuncishiswe izikhala. Ngokuvumelana nalokho, ngokushintsha kusuka ku-5w30 kuya ku-5w40, ngaleyo ndlela uthuthukisa ukusebenza okuguquguqukayo futhi wandise impilo yeyunithi yamandla. Qaphela ukuthi endaweni kawoyela ebukekayo kakhulu, kusetshenziswa umzamo owengeziwe ukuze u-crankshaft, ngakho izinga lokusetshenziswa kukaphethiloli cishe ngeke lehle kakhulu.
Izimo lapho ukuguquka kusuka ku-5w30 kuya ku-5w40 kungafuneki kakhulu:
- emiyalweni, umenzi wenqabela ukusetshenziswa kwezinye izinhlobo zamafutha kanye nezinto zokugcoba;
- imoto entsha muva nje evela e-salon ngaphansi kwewaranti;
- ukwehla kwezinga lokushisa lomoya.
Okunye okuyingozi kakhulu enjinini yisimo sokuxuba izinto zokugcoba ezinoketshezi oluhlukene. Amafutha awagcini nje ngokugcoba izindawo ezingaphezulu, kodwa futhi asusa ukushisa ngokweqile. Uma sihlanganisa imikhiqizo emibili nge-fluidity ehlukene kanye nama-viscosity coefficients, injini izoshisa ngokweqile. Le nkinga ifaneleka kakhulu kumayunithi wamandla wesimanje anembe kakhulu. Futhi uma esiteshini senkonzo unikezwa ukuthi ugcwalise 5w30 esikhundleni sika-5w40, okugqugquzela lokhu ngokuntuleka kohlobo oludingekayo lokugcoba endaweni yokugcina impahla, akufanele uvume, ngoba ngemva kokukhwabanisa okunjalo ukuchithwa kokushisa kuzoba kubi kakhulu, okungukuthi egcwele inqwaba yezinkinga ezihlobene.
okutholakele
Ngokusekelwe kukho konke okungenhla, siphetha ngokuthi ukushintshela kolunye uhlobo lukaphethiloli kanye nezinto zokugcoba kungenzeka kuphela ngemva kocwaningo oluningiliziwe lwezimpawu zeyunithi yamandla kanye nezidingo zomenzi. Kunconywa ukuthi ugweme ukuxuba amafutha avela kubakhiqizi abahlukene nasezisekelweni ezahlukene - ama-synthetics, ama-semi-synthetics. Ushintsho olunjalo luyingozi ezimotweni ezintsha. Uma i-mileage inkulu, kuyadingeka ukubonisana nochwepheshe.
