Amafutha ukusetshenziswa injini. izizathu eziyisithupha

Akekho ongalichaza thola umshayeli ababengeke babe exinwe anda uwoyela ukusetshenziswa. Ikakhulukazi isono uma lokhu kwenzeka ngaphezulu nge injini entsha. Sethula izizathu ezijwayeleke kakhulu okuyiwona kukhona ukusetshenziswa lamafutha e injini.

1. ingcindezi ngokweqile kule crankcase

Ukuze zonke izinjini libhekene igalelo-by. Ngenxa okusezingeni eliphezulu amagesi ingcindezi amandla omlilo kungekho ukuwa emasongweni piston futhi zibe crankcase. Uma, ngenxa ukugqoka we valve, izindandatho pistons blowby izinga idlula ejwayelekile ke motor izindlu kukhona kakhulu umfutho ophakeme, namafutha kufanele bagqugquzela uphawu. Isibonelo engokomfanekiso - kophawu valve stem ibhekene nengcindezi high load yakho iphezulu kakhulu. Lokhu kuholela yokuthi ukusetshenziswa uwoyela yenjini luyanda kakhulu.

2. inhlangano engalungile ikhanda isilinda

Uma inhlangano ayilungile izingxenye zingavela izakhi etshekile. Ngenxa yalokho, ngo-esifundeni omlilo ekamelweni akhiwa ngombiko ngeNkandla, ivimbela indlela eya wesifunda uwoyela. Kufanele sihlonishwe kuleli ukulandelana kokuqina inqubo kanye engela screwing amabhawudo ukuvimbela warping.

3. Kahle amafutha engine

Lapho usebenzisa i-amamaki okungafanele noma abampofu uwoyela ngeke ukuqinisekisa ukusebenza onokwethenjelwa injini zonke izindlela ezisebenza. Ngokwesibonelo, kwandisa injini bafake siqala abandayo, izimo zokusebenza ephezulu lokushisa, nabanye ngesikhathi. Amafutha kumelwe ilingane kahle imiyalelo nomkhiqizi umshini sika. Futhi zombili izakhiwo ukusebenza viscosity.

4. Wear futha (fuel amaphampu , umfutho ophakeme)

Ngo-25% amacala okusezingeni eliphezulu ukusetshenziswa amafutha injini kwenzeka ngenxa ukugqoka okusemgqeni umjovo futha. Igrisi futha izingxenye wenziwa nge wesifunda ohambelana motor. Uma izakhi futha umjovo ezigugile, kuyilapho pistons, amafutha angangena endaweni yokusebenza kwe-futha. Kukhona-ke ixubene udizili kanye uzothola ekamelweni amandla omlilo. Ukuze banciphise ukusetshenziswa wamafutha injini, kuyadingeka ukuthi ihlole okusemgqeni futha, ikakhulukazi diesel.

5. amasilinda etshekile

On amasilinda skew kubonisa engalingani contact patch nge izindawo ehlukile ezomile esebenza isilinda emkhonweni. Uma odongeni elingaphandle liner isilinda kukhona izindawo engalingani samanje, kuyisibonakaliso ecacile buckling. Ngenxa yalokho - emasongweni piston ayikwazi ukunikeza ezingeni ofanele uphawu, namafutha agelezela egumbini amandla omlilo. Ngaphezu kwalokho, waqinisa ku crankcase injini. Ezinye izinto okungenzeka skew zihlanganisa :. imishudo Irregular, contact ukugqwala, ungcolisa amasistimu Ukuphola, njll Sicela ulungise skew, futhi ukusetshenziswa uwoyela yenjini kuyehla kakhulu.

6. Irregular yesondlo

Ukwahluleka okuthobela nanoma enqunyiwe ngumkhiqizi we imoto wokuhlola PERIODICITY kuwo iyohlale singcoliswe uwoyela. Kusukela ngesikhatsi operation kancane kancane washisa okufakiwe iphakethe, kunobungozi ukuwohloka. Ukuze ugweme zokugwema ukuphuka, zidinga njalo uphole kuze amafutha injini.
