Uwoyela nenjini kuqala ebusika
Ubusika yisikhathi esinzima kakhulu sonyaka ezinjini zezimoto, ezibhekana nenani elikhulu lemithwalo eyengeziwe. Iresiphi yezinkinga ezinjalo ngamafutha alungile, okuvumela injini ukuthi isebenze kalula futhi ikhulule umnikazi wemoto yokucindezeleka nezindleko ezingadingekile.
Ukusetshenziswa kukaphethiloli okukhulu kakhulu nokulayisha ezingxenyeni zenjini kwenzeka uma iqaliswa, ikakhulukazi uma siqala injini ekuseni ebusika, emazingeni okushisa aphansi. Yilapho uhlelo lokugcoba kufanele lunikeze ngokushesha amafutha ezingxenyeni ezibandayo ezihambayo eziphumule isikhathi eside, ukunciphisa ukungqubuzana okubangelwayo ngokushesha ngangokunokwenzeka futhi zinikeze ukuthambisa okwanele, ukuvimbela ukuguga. Uma kucatshangelwa ukuthi injini yemoto evamile kunezingxenye ezingamakhulu amaningana zokusebenza futhi ukusebenza kwazo zonke kudinga ukugcotshwa okufanele, umuntu angacabanga ukuthi lo msebenzi ubaluleke kangakanani kulo lonke uhlelo lwamafutha kanye namafutha ngokwawo.
Ukuvikelwa kwe-friction
Enye yezinkinga ezibalulekile ezihlobene nokusebenza kahle kwenjini ebusika i-viscosity kawoyela (ibanga le-SAE viscosity). Ngakolunye uhlangothi, uwoyela "owuketshezi" noma "oluketshezi", lapho ipompo ikwazi ukuyithatha ngokushesha ku-sump futhi isakaze kuwo wonke uhlelo, ngakolunye uhlangothi, i-viscosity ephansi kakhulu inciphisa ukuvikela kwayo ukungqubuzana. Kufanele futhi kukhunjulwe ukuthi njengoba izinga lokushisa enjini likhuphuka, i-viscosity yamafutha izokwehla, futhi lokhu kuzothinta ukushuba kwamafutha "ifilimu" esakazwa phezu kwemishini. Ngakho-ke, isihluthulelo sempumelelo siwukuthola "incazelo yegolide" yomkhiqizi kawoyela, okuqinisekisa ukugcotshwa okusheshayo kwenjini ngesikhathi sokuqalisa kokuqala kanye nokusebenza kwayo isikhathi eside ngokuvikelwa kwamafutha okufanele.

I-viscosity yamafutha
Ukumakwa kwebanga le-viscosity kusinika ulwazi mayelana nezimo zokusebenza zamafutha. Ukunquma imingcele yasebusika yamafutha kuvumela ukuqhathanisa izakhiwo zokushisa eziphansi. Lokhu kusho ukuthi uwoyela "0W" uzohlinzeka ngemingcele efanayo yokugeleza kwamafutha ku -40o C kawoyela "5W" ngo - 35o C, namafutha "10W" - - 30o C i "15W" kuya - 25o C. Kubalulekile futhi uma sisebenzisa amafutha amaminerali, uwoyela wokwenziwa, noma umkhiqizo owenziwe ngabo bobabili lobu buchwepheshe.
Ngaphezu kokukhethwa okulungile kwamafutha kanye nokushintshwa kwayo kwe-cyclic, kufanelekile ukukhumbula imithetho embalwa eyisisekelo yokunakekelwa kwansuku zonke kwenjini yemoto. Gwema ukuma isikhathi eside ngemva kokuqalisa injini, okuvame ukuba njalo, ikakhulukazi ekuseni kuneqhwa lapho ushiya imoto ihleli imizuzu embalwa. Lona umkhuba ojwayelekile wokufakwa ngaphakathi kwemoto.
kanye namafasitela aqeda uqhwishi anomoya.
Okubaluleke ngokufanayo ukushintshwa kwamafutha ngesikhathi kanye nesihlungi, ngokuhambisana nezincomo zomenzi, nokuqapha okuhlelekile kwezinga lawo. Lokhu kuqinisekisa ukusebenza okude nokungenazinkinga kwenjini, kungakhathaliseki ukuthi yisiphi isikhathi sonyaka kanye nezimo zezulu ezikhona.
