Izimpawu ze-Solenoid engalungile noma enephutha ye-Valve Timing (VVT)

Izimpawu ezijwayelekile ze-solenoid ye-VVT embi zifaka ukukhanya kwe-Check Engine okuzayo, uwoyela wenjini engcolile, injini engasebenzi kahle, kanye nokonga kahle kukaphethiloli.

Ekuqaleni kuya maphakathi nawo-1960, iziqhwaga zezimoto zaseMelika uChrysler, Ford, noGeneral Motors zazibusa imigwaqo nemigwaqo emikhulu ezweni lonke. Lapho kukhishwa imoto ngayinye entsha, i-Big Three yafunda okwengeziwe mayelana nokusebenza kwenjini nendlela yokukhipha wonke amandla ehhashi aphume ezinjinini zawo ngokuzilungisa mathupha ukucaciswa kwamavalvu kanye nesikhathi sokubasa. Enye yentuthuko enkulu kwaba ukuthuthukiswa kwe-Valve Valve Timing (VVT), uhlelo olusha olwasebenzisa ubuchwepheshe be-elekthronikhi obuthuthukisiwe (okwangaleso sikhathi) ukuze bunikeze amasiginali kagesi aguquguqukayo asuka ohlelweni lokubasa nge-valve eshintshashintshayo yesikhathi solenoid. Namuhla, uhlelo lwe-VVT lungatholakala cishe kuzo zonke izimoto zokukhiqiza ezithengiswa e-US.

Umkhiqizi ngamunye wemoto unohlelo lwakhe oluhlukile lwe-VVT, kodwa iningi labo lithembele ku-valve esebenza ngokugcwele ye-solenoid valve ukuze ulawule ukugeleza kukawoyela ohlelweni lwe-VVT uma luvuliwe. Le sistimu ivamise ukwenziwa isebenze lapho injini ilayishwe kakhulu. Ezinye izibonelo zalokhu zihlanganisa lapho imoto ithwele isisindo esengeziwe, ukushayela ikhuphuka, noma lapho ukusheshisa kusheshiswa ukulawulwa kwe-throttle. Lapho i-VVT ​​solenoid icushiwe, uwoyela uqondiswa ukugcoba uchungechunge lwezikhathi ze-valve kanye nokuhlanganiswa kwegiya. Uma i-solenoid ye-VVT ihluleka noma ivinjiwe, ukuntuleka kokugcotshwa okufanele kungabangela ukuguga ngaphambi kwesikhathi noma ukwehluleka okuphelele kweketango lesikhathi negiya.

Kunezinye izinkinga eziningana ezingase zenzeke lapho i-VVT solenoid iguga noma iphuka, okungaholela ekuhlulekeni okuphelele kwenjini. Ukunciphisa amathuba okuba kwenzeke lezi zimo ezimbi, nazi izimpawu ezimbalwa eziyisixwayiso ezingase zibonise inkinga nge-VVT ​​solenoid. Nazi izimpawu ezimbalwa ze-solenoid ye-VVT egugile noma ephukile.

1. Hlola ukukhanya kwenjini kuyakhanya.

Njengoba izimoto zesimanje zilawulwa injini control unit (ECU), cishe zonke izingxenye ngabanye zilawulwa ECU. Uma ingxenye eyodwa iqala ukwehluleka, i-ECU igcina ikhodi ethile yenkinga evumela umakhenikha osebenzisa isithwebuli azi ukuthi kunenkinga. Uma ikhodi isikhiqiziwe, izobonisa umshayeli ngokukhanyisa isexwayiso mayelana nendawo ethile. Ukukhanya okuvame kakhulu okuza lapho i-VVT ​​solenoid ihluleka ukukhanya kwe-Check Engine.

Ngenxa yokuthi umkhiqizi wemoto ngamunye usebenzisa amakhodi ahlukene, kubaluleke kakhulu kumnikazi wemoto ukuthi axhumane nomakhenikha wasendaweni onesitifiketi se-ASE ukuze ahlole imoto, alande ikhodi ngethuluzi lokuxilonga elilungile, futhi anqume umthombo oqondile wenkinga. Eqinisweni, kunenqwaba yamakhodi enkinga ye-VVT solenoid yawo wonke umkhiqizi wezimoto. Uma umakhenikha esenalolu lwazi lokuqala, angaqala ukuxazulula inkinga ethile.

2. Amafutha enjini angcolile

Lokhu kuyimbangela enkulu kunophawu. I-VVT ​​solenoid isebenza kahle kakhulu lapho uwoyela wenjini uhlanzekile, ungenayo imfucumfucu, noma ulahlekelwe ukuthambisa kwawo noma i-viscosity. Lapho uwoyela wenjini ugcwala udoti, ukungcola, noma ezinye izinhlayiya zakwamanye amazwe, uvamise ukuvala indlela esuka ku-solenoid iye ochungechungeni lwe-VVT negiya. Uma uwoyela wenjini yakho ungashintshwanga ngesikhathi, ungalimaza i-VVT ​​solenoid, isekethe ye-VVT, kanye nesitimela segiya.

Ukuze ugweme lesi simo, qiniseka ukuthi ushintsha uwoyela wenjini yakho ngokulandela izincomo zomkhiqizi wemoto. Izinga likawoyela eliphansi lingadala nezinkinga nge-VVT ​​solenoid nezinye izingxenye zesistimu yesikhathi.

3. Injini engasebenzi kahle

Imvamisa, uhlelo lwe-VVT ngeke lusebenze kuze kube yilapho injini ikwi-RPM ephakeme noma ilethwa esimweni sokuthwala, njengalapho ushayela ukhuphuka. Kodwa-ke, uma i-solenoid ye-VVT inephutha, kungenzeka ukuthi izohlinzeka ngamafutha enjini engeziwe kumagiya e-VVT. Lokhu kungaholela ekungasebenzini kahle kwenjini, ikakhulukazi, ijubane lenjini lizoshintshashintsha lapho isistimu yenziwe yasebenza. Uma kungahlolisiswa ngokushesha, lokhu kungaholela ekugugeni ngaphambi kwesikhathi kwezingxenye ezengeziwe zenjini. Uma injini yakho ingazinzile ngokungenzi lutho, bona umakhenikha oqinisekisiwe ngokushesha ngangokunokwenzeka.

4. Ukunciphisa ukusetshenziswa kukaphethiloli

Inhloso yesikhathi se-valve eguquguqukayo iwukuqinisekisa ukuthi amavalvu avuleka futhi avale ngesikhathi esifanele ukuze kuthuthukiswe ukusebenza kwenjini nokunciphisa ukusetshenziswa kukaphethiloli. Lapho i-solenoid ye-VVT ihluleka, lonke uhlelo lungaba sengozini, okungabangela ukuthi ama-valve okuphuza nawokukhipha avuleke futhi avale ngesikhathi esingalungile. Njengomthetho, lokhu kuholela ekwehleni okukhulu kokusetshenziswa kukaphethiloli.

Uma ubona noma yiziphi izimpawu ezingenhla eziyisixwayiso zevalvu eshintshashintshayo ehlulekayo noma enephutha ye-solenoid valve, xhumana nomakhenikha oqinisekisiwe we-AvtoTachki ASE wangakini. Bangakwazi ukuhlola imoto yakho, bashintshe i-valve yesikhathi solenoid uma kunesidingo, futhi bagcine imoto noma iloli lakho lisebenza kahle.
