Le viscosity ioli nempembelelo yayo injini yesithuthi

Nayiphi na into engamanzi abe viscosity, eyona nto luphawu imisela fluidity yayo. ioli Automotive yenzelwe ukwenza iindidi ngeendidi zemisebenzi ukuze parameter nganye impembelelo yayo kumgangatho lulonke. Le viscosity weoli akukho ngaphandle.

Ingxaki lobuchule ephambili nayiphi na oyile injini - ukunqanda iimpikiswano zochuku ezishukumayo ngexesha lokusebenza injini. Ngokusesikweni, lo amandla zochuku kufuneka ibe ncinci ioli ihlala phezulu, iimpawu zayo kufuneka ahlale rhoqo phezu ebanzi uluhlu lobushushu.

Ukufezekisa le ngcamango xa efundisa, yaye udale into ethe idibana zonke iimfuno, kuba nzima kakhulu. Ukongeza, nceda wazi ukuba ngexesha intshukumo wolayisho esoloko itshintsha, yaye iqondo lobushushu oyile injini izithuthi ziya kwahluka kakhulu, kwezinye Imizuzu iya degrees 140-150.

Noko ke, iingcali njalo sisebenzela ukwenza i oyile injini, nto leyo eza kuba kufutshane kwizakhiwo zayo imiqathango efunekayo. Inzululwazi wenze kulo ndawo kakhulu linyathelo elibheka phambili, ngoko iinjini namhlanje kakhulu ngakumbi enamandla nolusebenzayo ababengaphambi zayo, yaye basebenza ixesha elide.

Le viscosity yamafutha yenye parameters ibalulekileyo. Nangona injini iyabanda okanye esebenza lisebenze kangangoko, i-oyile injini kokuqala izokhula. Kule uqhagamshelo kukho imfuneko yokuba oyile kufuneka ahlale elulwelo phantsi kwazo naziphi na iimeko, nkqu ukuba iqondo lobushushu ngaphandle kakuhle ngaphantsi zero. Le fluidity olungcono neoli, kokukhona kuya kukhusela injini ngexesha lomsebenzi.

Isalathisi se viscosity

Ukuze ubone viscosity leoli, iingcali ziye zaziswa index okhethekileyo, nto leyo ibonisa ukuxhomekeka kwe parameters eziphambili (kubandakanywa viscosity) obushushu. Ukuba uphakamile lo Isalathisi, kokukhona kungcono ioli ugcina fluidity kwayo kumaqondo obushushu aphantsi.

I oyile kufuneka phantsi kwazo zonke iimeko ahlale kumalungu injini, kodwa kwangaxeshanye ukugcina flow yayo. Ukuhlelwa oyile yenziwa kwisalathiso, njengoko yenye yeempawu ezibalulekileyo, leyo ukusa kumkhamo othile ibonisa iimpawu eziphambili.

5W index ibonisa ukuba injini esebenzisekayo maxa wambi amaqondo obushushu - degrees 35 ngaphandle preheating. Okuya kusiba phantsi ubushushu, ioli luthe uya kuba, yaye kunzima ukuba 'ubambe "injini, oku kuthetha ukuba starter akakwazi yesingxobo injini. Xa ukhetha i oyile motor ethile kufuneka sinikele ingqalelo kwimisebenzi ephambili, kodwa singalibalanga izindululo iimoto lomenzi. Kuyimfuneko ukuba bakuthathele ingqalelo kuyilo injini, iqondo imandundu, iindidi zixhaphakileyo yokusebenza, njalo-njalo.

ngendlela injini

Ukongeza, le viscosity oyile kuchaphazela ukusebenza injini, oko kukuthi unikezelo amandla. Xa injini kokwenza ezinye lwe-eneji esetyenziswa kwiimfuno zayo zangaphakathi, ngamanye oku kuthetha ukuba isithuthi ifuna amandla okoyisa imikhosi frictional evela iindawo ezahlukeneyo zoqhagamshelwano. I engcono ngakumbi ngobuchule iya kuba ioli, amandla ngaphantsi utshe kulo.

esetyenziswa ngoku amafutha Ulwahlulo, wangena ngaphezu American Society of Automotive Iinjineli. Ukuze ufumane olunye okanye kwelinye udidi, i oyile kufuneka ihlangabezane neemfuno ezithile. viscosity Kinematic of i oyile eliqingqwe 40 no-100, yaye ilinganiswa ngokugqithisela ityhubhu ekhethekileyo egosogoso - viscometer. Ngokwesiseko oku kumiselwa viscosity kanye yeoli, nto leyo esetyenziselwa ukuchonga ifomyula okhethekileyo. mvavanyo ukujonga umgangatho leoli, kwakunye usayino uhlobo ethile.
