Kungenzeka yini ukuqeda imfucuza kawoyela injini ngokuyishintsha

Cishe wonke umnikazi wemoto uyesaba futhi ethuke kakhulu lapho izinga likawoyela emotweni lehla. Phela, lokhu kubonisa ukungasebenzi kahle kwenjini kanye nokulungiswa okuzayo. Ngakho-ke, umshayeli udinga ukuqapha izinga ukuze agweme izindleko eziphezulu.

Ingabe izinga likawoyela wenjini lihlala lehla ngenxa yentuthu?

Ukushiswa wukushiswa kwamafutha enjinini. Kodwa "ingakwazi ukushiya" injini hhayi kuphela ngesikhathi somlilo, kodwa ngenxa yezizathu eziningi:

1. Uwoyela ungavuza ngaphansi kwesembozo sevalvu lapho ukrufulwe kabi noma i-gasket yonakalisiwe. Ukubona le nkinga akunzima, udinga ukubheka ngaphansi kwe-hood.
2. I-crankshaft oil seal nayo ingaba yimbangela yokuvuza kwe-lubricant. Ukubona le nkinga, ungabheka indawo lapho imoto yayikhona futhi uma kukhona i-puddle yamafutha, khona-ke kungenzeka ukuthi lokhu kuyisici samafutha. Lena inkinga evamile. Kungenzeka ngenxa yamafutha amabi noma ukuguga kwe-oil seal ngokwayo.
3. Lapho beshintsha isihlungi sikawoyela, bangakhohlwa ukufaka ishingamu yokuvala, noma bangaqinisi ngokuphelele isihlungi ngokwaso. Kungase futhi kubangele ukuvuza. Hlola ukuthi isihlungi sisonte kanjani, kanye nekhwalithi yerabha ukuze ivalwe.
4. Esinye isizathu esilula kungaba ama-valve stem seal (abuye abe ama-valve seal). Zenziwe ngenjoloba ekwazi ukumelana nokushisa, kodwa ihlala irabha, futhi ngenxa yokushisa okuphezulu, izigqoko ziqala ukubukeka njengepulasitiki, engenzi umsebenzi wayo futhi i-lubricant iqala "ukushiya".

Ingabe ukutubeka kukawoyela kuncike kuwo ngokwawo

Oh impela. Uwoyela okhethwe ngokungalungile ungase ungafinyeleli izindinganiso zale njini futhi kungase kubangele ukutubeka.

Imaphi amapharamitha kawoyela athinta imfucuza

Ziningi izici ezibangela inani lamafutha asha enjinini:

• Ukuhwamuka ngokwendlela ye-Noack. Le ndlela ibonisa ukuthambekela kwe-lubricant ukuhwamuka noma ukushiswa. Uma le nkomba iphansi, (ekhonjiswe ku-%), iba ngcono (iyancipha kancane). Izithambisi ezisezingeni eliphezulu kufanele zibe namaphesenti angaphansi kuka-14 kule nkomba.
• Uhlobo lwamafutha esisekelo. Kusukela esigabeni esidlule, unganquma ukuthi "isisekelo" sasisihle kangakanani ngesikhathi sokukhiqiza. Lapho inombolo kaNoack iphansi, “isisekelo” sasiba ngcono.
• I-Viscosity. Lapho i-viscosity iphezulu, inkomba ye-Noack iyancipha. Kungakho, ukuze unciphise imfucuza, ungashintshela kuwoyela we-viscous ngaphezulu. Isibonelo, ugcwalisa uwoyela we-10W-40 futhi ngokukhathala okuningi, ungashintshela ku-15W-40 noma ku-20W-40. Kuye kwafakazelwa ukuthi umehluko phakathi kwemfucuza ye-10W-40 ne-15W-40 cishe amayunithi angu-3.5. Ngisho nomehluko onjalo obonakala umncane ungathinta ukusetshenziswa.
• I-HTHS. Imele ukuthi "High Temperature High Shea", uma ihunyushwa, izoba "High Temperature - Big Shift". Inani lale nkomba linesibopho se-viscosity yamafutha. Izimoto ezintsha zisebenzisa amafutha anenkomba yaleli nani engaphansi kuka-3,5 MPa * s. Uma lolu hlobo lwe-lubricant luthululelwa emotweni yasebekhulile, khona-ke lokhu kuzoholela ekunciphiseni kwefilimu yokuzivikela kumasilinda kanye nokuguquguquka okukhulu, ngenxa yalokho, ukwanda kwemfucuza.

Imaphi amafutha anciphisa ukusetshenziswa hhayi ngenxa yemfucuza

Umthamo we-lubricant ovuthayo ungancishiswa ngosizo lwezithako. Kunenani elikhulu labo. “Zifiphalisa” imihuzuko kusilinda, ngaleyo ndlela zinciphise udoti.

Indlela yokukhetha amafutha angapheli

Ukuze ungabalali kahle, ungasebenzisa izindlela ezimbili:

1. Buka izibuyekezo. Ungaya esizeni ukuze udayise izinto zokugcoba futhi ubone ukubuyekezwa kwenketho ngayinye oyithakaselayo. Ungaphinde uye ezinkundleni ezehlukene lapho bedingida khona izinto zokugcoba izinjini, maningi.
2. Zihlolele wena. Le ndlela ifanele abantu abathanda ukuzifaka engozini noma abangakholwa ukubuyekezwa. Uma unje, khona-ke leli bhizinisi lingakwazi ukudonsa isikhathi eside, ngoba udinga ukuthenga amafutha, ugcwalise, uqhube amakhilomitha ayizinkulungwane ezingu-8-10, bese uhlola izinga layo nezinye izici.

Uwoyela ujwayele ukusha ngisho nasenjinini entsha. Uma izinga lehla, udinga ukuhlola isivalo sikawoyela we-crankshaft, isembozo sevalvu, izigxivizo ze-valve stem kanye nezindlu zokuhlunga uwoyela ukuthi azivuzi yini. Futhi, ngaphambi kokuthenga amafutha, kufanele uthole ukuthi yimaphi amafutha afanele injini yakho.

Ukuze unciphise ukutubeka, ungashintshela ku-lubricant enkulu. Futhi uma amafutha "eshiya" amalitha amakhilomitha ayizinkulungwane ezingu-1-2, khona-ke kuphela ukulungiswa okukhulu kuzosiza. Inhlanhla emgwaqeni futhi ubuke imoto yakho!
