Yini ekuwoyela wenjini yesikhathi? Lesi isizathu sangempela senkathazo.

Abantu abake baba nenkinga nge-timing chain stretch cishe bezwe noma bafunde ndawana thize ukuthi kuhlobene nokushintsha uwoyela wenjini. Uma beqonda oomakhenikha, bayazi ukuthi akukhona ukugcoba iketango ngokwalo. Pho kungani?

Ngaphambili, uchungechunge lwezikhathi lwaluqine kangangokuthi kwakungenakwenzeka ukushintshwa. Okungcono kakhulu, lapho ulungisa injini eyinhloko. Namuhla kuwumklamo ohluke ngokuphelele. Ezinjinini zanamuhla, amaketanga made kakhulu futhi anwebeka phakathi kwamagiya amaningana.. Ngaphezu kwalokho, zikude kakhulu komunye nomunye, ngoba ama-camshafts atholakala ku-fuselage, i.e. eduze kwe-crankshaft, kakade umlando.

Konke lokhu kusho ukuthi iketanga kufanele liqiniswe kahle hhayi kuphela kuma-sprockets, kodwa futhi phakathi kwawo. Le ndima yenziwa yizinhlobo ezimbili zezinto - okuthiwa yiziqondiso kanye nama-tensioners. Ama-skid azinzisa iketango futhi aliqinise ezindaweni lapho kushuba khona phakathi kwamasondo., kanye nama-tensioner (ngokuvamile i-tensioner eyodwa - ephawulwe ngomcibisholo obomvu esithombeni) iqinisa lonke iketango endaweni eyodwa ngesinye sezicathulo (esithombeni i-tensioner icindezela ku-slide).

I-timing chain tensioner iyingxenye ye-hydraulic elula. (uma kuwumshini, ungafundi ngokuqhubekayo, isihloko sikhuluma ngama-hydraulic). Isebenza ngokugcwele ngokuzenzakalelayo ngokusekelwe ekucindezelweni kwamafutha okukhiqizwa ohlelweni. Lapho ingcindezi iphakeme, i-voltage inkulu, iphansi, iyancipha. Iketango kufanele liqine kakhulu, isibonelo, lapho umthwalo enjini ukhula, kanye nalapho iketango noma ezinye izakhi ziguga. I-tensioner ibe isinxephezela ngokuguga ezingxenyeni zesikhathi. Kukhona okubanjwayo okukodwa - isebenza ngawo lowo mafutha athambisa injini.

I-tensioner idinga uwoyela omuhle.

Amafutha enjini angena ku-tensioner ngesikhathi sesigaba sokuqala sokusebenza, ngemva kokuqala injini, anogqinsi futhi abandayo. Ayikabi nalo izinga lokushisa elilungile okwamanje, ngakho-ke ayigelezi futhi. Ngemva kwesikhashana, lapho ifudumala, yenza umsebenzi wayo ngamaphesenti angu-100. Kodwa-ke, ngokusetshenziswa kukawoyela kanye nokungcoliswa, isikhathi phakathi kokuqala nokusebenza kahle kwamafutha, futhi yingakho i-tensioner, iyanda. Iyakhula nakakhulu uma uthela amafutha e-viscous kakhulu enjinini. Noma uyishintsha ngokungavamile.

Safika enhliziyweni yenkinga. I-tensioner engalungile Lokhu akwenzi nje kuphela ukuthi iketango likhululeke kakhulu emaminithini noma imizuzu yokuqala yokusebenza, kodwa futhi lapho amafutha "aminyene" noma engcolile, i-tensioner ayiphenduli kahle. Ngenxa yalokho, uchungechunge lwesikhathi oluqiniswe ngokungalungile lubhubhisa izakhi ezisebenzisanayo (izilayidi, amagiya). Kubi kakhulu amafutha angcolile angase angafinyeleli ku-tensioner engcolile kakade futhi lena ngeke isebenze nhlobo (shintsha i-voltage). Uma kukhuphuka ukugqokwa kwezinto zokukhwelana, kudlala kakhulu, iketango liguga kakhulu size sifike lapho uzwa khona ...

isikrini seketango

Akunakwenzeka ukuhlola isimo se-timing chain drive nganoma iyiphi indlela engahlaseli ngaphandle kokudiliza yonke indlu nokuhlola izingxenye zayo. Ngokuphambene nokubukeka, lokhu kuyinkinga enkulu, kodwa okuningi ngalokho kamuva. Okubaluleke nakakhulu ukuthi umsindo ovela ku-timing case, ongahlali uthathwa umakhenikha, ingasaphathwa eyokuthenga imoto esetshenzisiwe, kuwuphawu lokuguga ku-timing chain drive. Awukho umsindo, ngaphandle kweketango lesikhathi elixegayo. Ukushesha kokuphendula komsebenzisi, izindleko ezingaba khona ziyancipha. Ezinjinini eziningi, kwanele ukufaka esikhundleni se-tensioner kanye neketanga, kwezinye isethi ephelele yezihlibhi, kanti okwesithathu, kulawo agugile kakhulu, amagiya asadinga ukushintshwa. Kuba kubi kakhulu uma inamagiya ane-variable valve timing. Lokhu vele kusho izindleko ezinkulungwaneni ze-PLN zezingxenye ezisele.

Kukhulu kakhulu lokhu ngokuvamile izinjini zochungechunge lwezikhathi ziyizinjini ezinhle. Nokho, akunakwenzeka ukuhlola le ndawo ngaphandle kokubamba umakhenikha kanye neshabhu. Isibonelo i-Audi, BMW noma udizili wakwaMercedes onamandla amakhulu. Uma yonke into ijwayelekile, khona-ke ihluleka kancane, inamandla futhi iyonga. Nokho, ngemva kokuthenga imoto ngeketanga eseluliwe, kodwa, ngokwesibonelo, hhayi okwamanje umsindo, kungase kuvele ukuthi ukuze ujabulele zonke izinzuzo injini enjalo diesel, udinga ukusebenzisa PLN 3000-10000 ibhande lesikhathi. esikhundleni. .
