"Uwoyela wenjini evuthayo" ubhekisela eqinisweni lokuthi uwoyela wenjini ungena ekamelweni elivuthayo lenjini futhi uhlanganyele ekushiseni kanye nengxube, okuholela ekulahlekeni kwamafutha enjini ngokushesha nokuvuza kwamafutha. Izinkinga ezivame kakhulu ezivame ukubangela injini "amafutha avuthayo" ama-valve oil seals namasongo e-piston. Ngakho-ke kuthiwani uma sehlulela ukuthi inkinga yeringi ye-piston noma inkinga yophawu lwamafutha e-valve? Ake sibheke ndawonye. Okokuqala, ake siqale siqonde imbangela yamafutha avuthayo

· Valve seal

I-valve oil seal ayicindezelwa ngokumelene nayo;

Ukuvunyelwa okukhulu phakathi komhlahlandlela we-valve nekhanda lesilinda;

Ukugqokwa kwe-valve oil seal, ukuguga ngokweqile kwesiqu se-valve kanye nomhlahlandlela we-valve;

Ukuguga kophawu lwamafutha e-valve kubangela ukuba amafutha ageleze eduze kwesiqu se-valve ukuya ekamelweni elivuthayo, okubangela ukuba amafutha ashise. ·Piston ring

Indandatho yepiston ifakwe ibheke phansi;

Indandatho yepiston ayinyakaziswanga njengoba kudingeka;

Ububanzi bangaphandle bendandatho yepiston buncane kakhulu futhi imvume phakathi kobubanzi besilinda inkulu;

Enqubweni yokugcinwa nokusetshenziswa, hlanza ngokunganaki indandatho ye-piston, i-piston kanye ne-cylinder wear;

Indandatho ye-piston inokumelana okungahambi kahle nokugqoka ngaphambi kwesikhathi, okubangela ukuba amafutha angene ekamelweni elivuthayo futhi ashise amafutha;

Ama-piston kanye nama-cylinder barrel agqokwa. Igebe phakathi kobubanzi bepiston nomgqomo wesilinda lidlula inani elishiwo. ·Ezinye izizathu

Indandatho kathayela ayifakwanga endaweni, okubangela izimpawu ze-groove kusilinda senjini;

Klweya udonga lwesilinda ngephutha ngesikhathi sokuhlanganisa;

Ukushisa okuphezulu kwenjini; (ungabheki ukuntuleka kwamafutha, ukuntuleka kwamanzi noma ukuntuleka kwamanzi)

Umphumela wokugcotshwa kwamafutha enjini mubi;

Ayifudumezi imoto, ibangele ukuguga;

Iphampu kaphethiloli ingena ekamelweni elivuthayo.
Yiziphi izindlela zokwahlulela ukushiswa kwamafutha enjini?

Kunezinhlobo ezintathu zokushiswa kukawoyela wemoto (ngokulandelana, uwoyela wenjini evuthayo emotweni ebandayo, uwoyela wenjini evuthayo uma usheshisa futhi ushisa uwoyela wenjini nganoma yisiphi isikhathi)

·Indlela yokwahlulela ye-valve oil seal burning oil burning

1) Izindlela zokwengeza nokukhulula i-throttle;

I-2) Idiphozithi ye-carbon eyingozi kanye nokuvinjelwa kwe-catalyst yezindlela ezintathu;

3) Uma i-exhaust iyintuthu eluhlaza okwesibhakabhaka, kusho ukuthi imoto isiwashisile uwoyela wenjini. Uma intuthu eluhlaza okwesibhakabhaka inyamalala ngemva kokushisa kwemoto, lolu hlobo lwamafutha enjini lungamafutha enjini apholile. (Lokhu kungenxa yokuthi uphawu lukawoyela we-valve luyaguga noma lonakele, okuholela ekuvaleni okungekuhle, futhi uwoyela ungena kusilinda usuka kuvalvu).

·Indlela Yokwahlulela Yamafutha Okushisa Endandatho Ye-Piston

1.Ngemva kwemoto eshisayo, kungakhathaliseki ukuthi ijubane elisheshayo noma inqubo ye-idling, inqobo nje uma ijubane likhuphuka ngokushesha, kuzophuma intuthu eluhlaza okwesibhakabhaka epayipini lokukhipha umoya. Lolu hlobo lokusheshisa okusheshayo lushisa amafutha. (Ukusheshisa okusheshayo kokushiswa kwamafutha ngokuyinhloko kubangelwa umphumela omubi wokuvalwa phakathi kodonga lwangaphakathi lwesilinda kanye nendandatho ye-piston, okubangela ukuba amafutha angene ekamelweni elivuthayo ngqo kusuka ku-crankcase);

2.Uma ulinganisa ukucindezela kwe-cylinder, uma kunenkinga ngendandatho ye-piston, inani lokugqoka lingahlulelwa ngedatha ye-cylinder pressure (uma ingekho kakhulu, noma inkinga ye-cylinder, ngokungeza i-ejenti yokulungisa, kufanele zilungiswe ngokuzenzakalelayo ngemva kwamakhilomitha angu-1500). ·Izindlela zokwahlulela ngezinye izizathu

Uma sekuqaliwe, kuyabonakala intuthu eluhlaza okwesibhakabhaka. Ngalesi sikhathi, uwoyela wenjini usuvele ubi kakhulu, futhi kungase kube nobungozi bokuphepha. Lolu hlobo lwamafutha lushiswa noma nini. (Injini iguge kakhulu, okuholela ekuvaleni kahle, okunikeza izimo ezivumayo zokushiswa kukawoyela. Ngalesi sikhathi, kufanele ilungiswe ngokushesha ukuze kugwenywe ukwehluleka okukhulu kanye nokulimala)
