Ukwehla kokusebenza - lokhu kungabonisani?

Uma uhamba ngemuva kwesondo, cishe ulindele ukuthi imoto yakho isebenze kahle - phela ukushayela okushelelayo kuncike ekufikeni emsebenzini ngesikhathi nokuba neholide eliyimpumelelo. Awekho ama-jerks, ukunyuka kancane kwejubane lenjini kanye nokushoda kwejubane akufuneki. Nokho, uma ukusebenza kwenjini kwehla, esinye sezimbangela eziyisikhombisa ezivame kakhulu ngokuvamile sisengozini. Sebelapha!

Uzofundani kulokhu okuthunyelwe?

• • Yini engabangela ukwehla ekusebenzeni kwenjini?
  • Okufanele ukubheke lapho injini ikhombisa ukungasebenzi kahle

Ngikhuluma nje

Ukwehla kwamandla enjini kuvame ukubonakaliswa yizijezi kuyunithi yokushayela, ukwanda kokungenzi lutho, ukwanda kokusetshenziswa kukaphethiloli kanye nokuqala kanzima kwemoto. Esimeni esibucayi, ibhayisikili lingase lingene esimweni esiphuthumayo noma lihlale ngokuphelele. Amaphutha avamile athinta ukusebenza kokushayela ahlanganisa iphampu kaphethiloli, ama-injection, inzwa yezinga lokushisa elipholile, inzwa ye-throttle position, imitha yobuningi bomoya, noma isikhathi esimile nesiqaphi sokuxhuma isihlungi sikaphethiloli. Ukushisa ngokweqile idrayivu kungaba yingozi ikakhulukazi esikhwameni sakho - ikakhulukazi uma ikhanda liphuka futhi lidinga ukushintshwa.

Kungaba yini izizathu zokwehla kwamandla enjini?

Ukugqokwa kwephampu yamafutha

Iphampu yamafutha ohlelweni lomjovo inikezela ngophethiloli ukusuka ethangini ukuya enjinini. Kanye nokugqoka okubalulekile uyeka ukusebenza ngaphansi kwengcindezi ephezulu, okuholela ngokuqondile ekunciphiseni kwamandla eyunithi yokushayela. Isizathu singase singalali nje kuphela ekugqokeni kwayo ngokweqile, kodwa futhi nokungcoliswa ukungcola nokugqwala, noma ngisho nokufaka i-refueling okuvamile ngaphansi kwe-¼ yevolumu yethangi.

Ama-injection avaliwe nesihlungi sikaphethiloli

Ama-injector anesibopho sokuhlinzeka ngophethiloli ngengcindezi efanele ekamelweni elivuthayo. Ukuze zisebenze ngempumelelo, kufanele zikhululeke, kanjalo ungakhohlwa ukufaka esikhundleni isihlungi sikaphethiloli ngesikhathi - kuye ngezincomo zomenzi wemoto kanye nekhwalithi yalesi sici sohlelo, isikhawu sisuka kumakhilomitha ayi-15 kuye kwangama-50 ayizinkulungwane. Ekuqaleni, njengoba ukonakala kwenjini kwanda, ukusebenza kwehla kancane. Ekugcineni, isihlungi esivalekile singakwenza ungakwazi ukuqhubeka nokushayela, futhi ungase unqume ukucela usizo lomgwaqo.

Ukungasebenzi kahle kwenzwa yokushisa

Lolu hlobo lwenzwa ludlulisa ulwazi mayelana nezinga lokushisa elipholile kusilawuli, ukuze ingxube ye-fuel-air yakheke ngezilinganiso ezifanele. Ngaphambi kokuba injini igcine ifudumala, ikhompyutha ikhetha umthamo omkhulu kaphethiloli maqondana nomoya, futhi ngemva kokufudumala, iyawehlisa. Ukungasebenzi kahle okungenzeka kuvame ukuvela ngenxa yesifunda esifushane kumtshina., futhi phakathi kwezimpawu eziqinisekisa lokhu, umuntu angabona ukwanda kokusetshenziswa kukaphethiloli, ubunzima bokuqala kanye nokwanda kwejubane elingenalutho.

Ukungasebenzi kahle kwe-Throttle Position sensor

Inzwa ye-throttle position izwa izinguquko ekuphambukeni kwe-throttle futhi idlulisele noma yiluphi ulwazi olunjalo kukhompuyutha eqapha ukusebenza kwenjini. Lokhu kuvumela isilinganiso esifanele sikaphethiloli ukuthi sikhethwe enanini lomoya odlula enjinini. Phakathi kwezizathu zokuhluleka kwenzwa kugqama ukulimala komshini, ukuthintana kabi kusixhumi sepulaki namasekethe amafushane angaphakathi ngenxa yomswakama le ngxenye noma ukuthintana kwayo namafutha. Uma kwenzeka ukusebenza okungalungile komtshina, kuvela ubunzima ngokuqala, ukwanda kokusetshenziswa kukaphethiloli, kanye nokuntuleka kwamandla kanye nama-jerks weyunithi yokushayela ngemuva kokwengeza igesi.

Ukungasebenzi kahle kwemitha yokugeleza komoya

I-flow meter ihlinzeka ikhompuyutha ngolwazi ngesisindo somoya owuthathayo ukuze ibale inani elifanele likaphethiloli okufanele lijovwe enjinini ngokuya ngesilinganiso esifanele sikaphethiloli nomoya. Ngenxa yalokho, injini isebenza kahle, inciphisa ukukhishwa kwezinto eziyingozi emvelweni, futhi ukuvutha kwayo kuhlangabezana nezindinganiso ezishiwo umenzi. Ngokuvamile ukwehluleka kwenzeka ngenxa yezixhumi zikagesi ezinephutha noma ukulimala kwezakhi zokulinganisa.... Ngenxa yalokho, ukukhiqizwa kwegesi ye-exhaust kuya ngokuya kukhuphuka ukusetshenziswa kukaphethiloli, isibani sesexwayiso senjini kudeshibhodi siyakhanya futhi injini iqala esimweni esiphuthumayo noma icime ngokuphelele.

Ukungasebenzi kahle kwedivayisi yokuqapha i-engeli yokuhola emile

Isikhathi sokuthungela ukuchezuka kwe-crankshaft phakathi nesikhathi lapho i-spark ivela ku-spark plug bese i-piston yenjini ifika enkabeni ephezulu efile. Ibizwa kanjalo iphuzu lapho i-piston isondela khona ekhanda le-cylinder futhi ngangokunokwenzeka ukusuka ku-crankshaft... Uma idivayisi elawula lokhu kumiswa isuswa (ngenxa yokuthi ithola amasiginali ayiphutha endaweni ye-camshaft noma izinzwa zokugoqa), iqala ukuvimba ukusebenza kwenjini ngamandla aphelele.

Ukushisa ngokweqile kwedrayivu

Uma izinga lokushisa leyunithi yokushayela liphezulu kakhulu futhi amandla ayo ehla, kufanelekile futhi ukubhekisisa isimo sayo. uhlelo lokupholisa lwepayipi elimele, ifeni noma iphampu... Noma yikuphi ukukhubazeka kuzo kungaholela ekuguqulweni kwezingxenye eziyinhloko zenjini (kuhlanganise nokuqhekeka kwekhanda) kanye nokulungiswa okwengeziwe okubizayo.

Njengoba ubona, ukusebenza kwenjini okwehlisa isithunzi akufanele kunganakwa ngoba kulula ukubhebhethekisa izinkinga, okungaholela ekwenyukeni okukhulu kwezindleko zokuyilungisa. Ngokushesha nje lapho uqaphela ukuthi amandla okushayela ehla, yisa imoto esikhungweni sesevisi - ke uzovimbela ukuhluleka okwengeziwe. Futhi uma kuziwa ekushintsheni izingxenye eziyinhloko zedrayivu, hlola amanani abo kuwebhusayithi ye-avtotachki.com - lapha ikhwalithi ihambisana nezintengo ezikhangayo!

Futhi hlola:

Ingabe kufanele ushayele injini yakho?

Hlola injini noma ukukhanya kwenjini. Kuthiwani uma livutha?

Ukungasebenzi kahle kwezinjini zikaphethiloli. Yini evame ukwehluleka e "uphethiloli izimoto"?
