Amafutha emoto - indlela yokukhetha

Ukugcwalisa ngamafutha enjini angalungile kungabangela umonakalo omkhulu kuyunithi yamandla. Ukuze ugweme izindleko eziphezulu zokulungisa, kufanelekile ukukhetha amafutha afanele.

Umthetho wokuqala nokuwukuphela kwesithupha kufanele kube ukulandela izincomo zomkhiqizi wenjini. Amayunithi kagesi esimanje ayizindlela ezenziwe kusetshenziswa ubuchwepheshe bamuva nje futhi ukwakheka kwawo ngokuya ngemingcele kuhambisana ngokuphelele. isiphetho. Ngakho-ke, uwoyela wenjini yesimanje uyisici sesakhiwo senjini ngakho-ke kufanele uhambisane nazo zonke izakhi zawo ngokwemishini, amakhemikhali nokumelana nokushisa.

Uwushintsha nini uwoyela?

Khumbula amafutha ebhokisini

Amafutha amaningi asetshenziswayo namuhla angamafutha okwenziwa, ahlinzeka ngokuvikeleka okungcono kakhulu nokupholisa izingxenye zenjini ezihambayo kunamafutha amaminerali. Futhi banamandla amakhulu okuhlakaza izinhlayiya ezivela ohlelweni lokusha, ezibanjwa kalula ngamasistimu okuhlunga.

Isici esibaluleke kakhulu nesinenzuzo uma kuqhathaniswa namafutha amaminerali i-viscosity ephansi yamafutha okwenziwa, okuvumela ukumbozwa okunembile kwamafutha ezindaweni ezingaphansi kokungqubuzana cishe kunoma yiliphi izinga lokushisa, ikakhulukazi emazingeni okushisa aphansi, lapho wonke uwoyela wenjini ushuba.

Ungahlanganisi uwoyela wokwenziwa namafutha amaminerali, futhi uma kunjalo, ne-semi-synthetic.

Futhi, ungasebenzisi amafutha okwenziwa ezinjini zezimoto ezindala ezinamamayela aphezulu, ngaphambilini ezazisetshenziswa ngamafutha amaminerali. Amafutha okwenziwa agcwele kuleli cala angabangela umonakalo omkhulu, ngoba izinto zokuhlanza nezingxenye zokuhlanza ezifakwe ekubunjweni kwazo zizoncibilikisa ukungcola okunqwabelene namadiphozithi angcolisa izingxenye zenjini. Ukwengeza, izigxivizo eziningi zenjini ezindala zenziwa ekwenziweni kwenjoloba engaklanyelwe ukusebenza ngokwenziwa kwamafutha okwenziwa. Ngakho-ke amathuba aphezulu okuvuza kukawoyela.

Okokugcina, kufanelekile futhi ukulandela umthetho wokusebenzisa amafutha avela kubakhiqizi abaziwayo nabaziwayo, nakuba intengo yabo yokuthenga ingase ibe phezulu kunabanye.

Iminyaka yokuhlangenwe nakho ihlala ikhokha ngekhwalithi yomkhiqizo, okuthi, esimweni sikawoyela wenjini, inqume ukusebenza nempilo yesevisi yenjini yemoto yethu.

Ngokwezindinganiso ezamukelwayo ze-SAE, i-viscosity kawoyela ikhonjiswa ngezinombolo ukusuka ku-0 kuye ku-60, kanti isikali samaphuzu ayi-6 "W" (ebusika) sisuka ku-0W siye ku-25W sinquma izinga lokushisa lapho i-viscosity ishintsha kakhulu kangangokuba uwoyela ujiya ufinyelele endaweni enjalo. isimo lapho iqala injini iba yinto engenakwenzeka.

Empeleni, imi kanje:

- ebangeni le-viscosity 0W, izinga lokushisa lisukela - 30 ° С ukuya - 35 ° С,

- 5W - 25 kuya - 30 ° С,

- 10W - 20 kuya - 25 ° С,

- 15W - 15°С kuya -20°С,

- 20W - 10°С kuya -15°С,

- 25 W - kusuka -10 ° C kuya ku-0 ° C.

Ingxenye yesibili yesilinganiso (isilinganiso samaphuzu angu-5, 20, 30, 40, 50 no-60) sinquma "amandla amafutha", okungukuthi, ukugcinwa kwazo zonke izakhiwo ebangeni lokushisa eliphezulu, i.e. 100°C no-150°C.

Inkomba ye-viscosity yamafutha e-synthetic motor isuka ku-0W iye ku-10W, futhi imvamisa uwoyela we-10W nawo ukhiqizwa njengama-semi-synthetic. Amafutha abhalwe ukuthi 15W nangaphezulu ngokuvamile angamafutha amaminerali.

Amafutha ezinjini zegesi

Hlola amafutha akho ngaphambi kokugibela

Zonke lezi zimpawu zingatholakala ekufakweni kwamafutha enjini ngayinye, kodwa ukuhlaziya kwabo akuphenduli umbuzo - kungenzeka yini ukuxuba amafutha, futhi uma kunjalo, yiziphi?

Yiqiniso, akukho okubi okuzokwenzeka enjini uma, ngenkathi sigcina imingcele yekhwalithi efanayo kanye nesigaba se-viscosity, sishintsha umkhiqizo - okungukuthi, umenzi. Ngemuva kokushayela inombolo enkulu yamakhilomitha, kungenzeka futhi ukusebenzisa uwoyela webanga le-viscosity ephakeme kakhulu, i.e. denser. Izovala injini kangcono, ithuthukise isimo sayo kancane, nakuba kufanele wazi ukuthi ngeke ilungise injini egugile.
