Imoto eyiChery EASTAR B11 enebanga elingu-80000 km, ifakwe umshini ozishintshayo kanye nohlobo lwenjini yakwaMitsubishi 4g63. Umsebenzisi ubike ukuthi injini yemoto iyazamazama ngemuva kokuyiqala, futhi imoto ebandayo ibucayi. Umnikazi wemoto uphinde wabika ukuthi kuyabonakala uma kulindelwe irobhothi (okungukuthi, uma imoto ishisa, injini inyakaza kakhulu ingenzi lutho).
Ukuhlaziywa kwamaphutha: enjinini yemoto elawulwa nge-elekthronikhi, izimbangela zejubane lokungenzi lutho elingazinzile ziyinkimbinkimbi kakhulu, kodwa amaphutha avamile esivinini sokungenzi lutho angahlaziywa futhi axilongwe kusukela kulezi zici ezilandelayo:
1. Ukwehluleka komshini
(1) Isitimela se-valve.
Izimbangela ezivamile zamaphutha yilezi: ① isikhathi esingalungile se-valve, njengokungaqondani kahle kwezimpawu zesikhathi lapho kufakwa ibhande lesikhathi se-valve, okuholela ekushiseni okungavamile kwesilinda ngasinye. ② Izingxenye zokudlulisa ama-valve zigugile kakhulu. Uma ikhamera eyodwa (noma ngaphezulu) igqokwe ngendlela engavamile, ukudonsa nokukhipha umoya olawulwa amavalvu ahambisanayo akulingani, okuholela ekuqhumeni kwamandla omlilo angalingani wesilinda ngalinye. ③ Ukuhlanganiswa kwe-valve akusebenzi ngokujwayelekile. Uma uphawu lwe-valve lungaqinile, ukucindezela kokucindezela kwesilinda ngasinye akuhambelani, futhi ngisho nesilinganiso sokucindezela isilinda siyashintshwa ngenxa yokubekwa kwekhabhoni okujulile ekhanda le-valve.
(2) I-cylinder block kanye ne-crank rod yokuxhuma indlela.
① Ukuvunyelwa okufanayo phakathi kwe-cylinder liner ne-piston kukhulu kakhulu, "izindawo ezintathu ezicacile" zeringi ye-piston azijwayelekile noma azinwebekanga, futhi "ukufanisa" kweringi ye-piston kuyenzeka. Ngenxa yalokho, ukucindezela kokucindezela kwe-cylinder ngayinye kuyinto engavamile. ② I-carbon deposition ejulile ekamelweni lokushisa. ③ Ibhalansi eguquguqukayo ye-crankshaft yenjini, i-flywheel kanye ne-crankshaft pulley ayifanelekile.
(3) Ezinye izizathu. Isibonelo, iphedi yonyawo lwenjini iphukile noma ilimele.
2. Ukuhluleka kwesistimu yokungenisa umoya
Izimo ezivamile ezidala amaphutha zihlanganisa:
(1) Ukuvuza kwama-valve amaningi noma ama-valve ahlukahlukene, njengokuvuza komoya kwe-gasket eningi edonsayo, ukuxegiswa noma ukugqabuka kwepulaki yepayipi levacuum, njll., ukuze umoya okungafanele ungene ungene kusilinda, uguqule ukuhlangana kwengxube, futhi kuholela ekushisweni kwenjini okungavamile; Lapho indawo yokuvuza komoya ithinta kuphela amasilinda ngamanye, injini izozamazama ngamandla, okunomthelela osobala esivinini esibandayo sokungenzi lutho.
(2) Ukusebenzisa kabi ngokweqile kuma-throttle namachweba okungenisa. Owokuqala wenza i-throttle valve ibhajwe futhi ivaleke ngokuxekethile, kuyilapho eyakamuva izoshintsha isigaba sokuthatha, esizothinta ukulawulwa nokukalwa komoya ongenisayo futhi kubangele isivinini esingazinzile sokungenzi lutho.
3. Amaphutha ajwayelekile abangwa amaphutha esistimu yokuphakelwa kukaphethiloli ahlanganisa:
(1) Umfutho kawoyela wesistimu awujwayelekile. Uma ingcindezi iphansi, inani lamafutha elijovwe kumjovo lincane, futhi ikhwalithi ye-atomization iba yimbi kakhulu, okwenza ingxube ku-cylinder ibe mncane; Uma ukucindezela kuphezulu kakhulu, ingxube izobe icebile kakhulu, okuzokwenza ukuvutha ku-cylinder kungazinzi.
(2) Umjovo kaphethiloli ngokwawo unephutha, njengokuthi imbobo yomlomo ivalekile, ivalve yenaliti ibanjiwe noma ishiswa ikhoyili ye-solenoid.
(3) Isignali yokulawula i-fuel injector ayijwayelekile. Uma isijojo sikaphethiloli sesilinda singase sibe nokungaphumeleli kokujikeleza, inani lomjovo kaphethiloli lomjovo kaphethiloli wale silinda lizongqubuzana nelamanye amasilinda.
4. Ukuhluleka kwesistimu yokuthungela
Izimo ezivamile ezidala amaphutha zihlanganisa:
(1) Ukwehluleka kwe-spark plug nocingo olunamandla kagesi kuholela ekwehleni noma ekulahlekelweni kwamandla enhlansi. Uma igebe le-spark plug lingalungile, intambo ene-voltage ephezulu ivuza ugesi, noma ngisho nenani lekhalori le-spark plug alifanelekile, ukusha kwesilinda nakho kuzoba okungavamile.
(2) Ukwehluleka kwemojula yokuthungela kanye nekhoyili yokuthungela kuzodala ukungasebenzi kahle komlilo noma ukuncipha kwamandla enhlansi enamandla amakhulu.
(3) Iphutha le-engeli yokubasa kusengaphambili.
5. Amaphutha ajwayelekile abangwa amaphutha esistimu yokulawula i-elekthronikhi yenjini ahlanganisa:
(1) Uma imojula yokulawula injini ye-electronic (ECU) kanye namasignali ahlukahlukene okokufaka ehluleka, isibonelo, isignali yesivinini se-crankshaft yenjini kanye nesiginali yesikhungo esifile se-cylinder top ingekho, i-ECU izoyeka ukukhipha isignali yokuthungela kumojula yokuthungela, futhi isilinda sizovutha kabi.
(2) Ukwehluleka kwesistimu yokulawula isivinini engenzi lutho, okufana ne-idle stepper motor (noma i-idle solenoid valve) ebambekile noma engasebenzi, kanye nokusebenza okungavamile kokuzifundela.
Thuthukisa izinyathelo:
1. Ukuqinisekiswa kokuqala kokwehluleka kwemoto
Ngemuva kokuxhumana nemoto enephutha, umnikazi waziswa ngophenyo ukuthi imoto ibidlidliza ngesivinini esingenzi lutho ngemuva kokuyiqala; Ngabheka i-spark plug ngathola ukuthi kune-carbon deposit ku-spark plug. Ngemva kokufaka i-spark plug, ngezwa sengathi i-jitter incishisiwe, kodwa iphutha lisekhona.
Ngemuva kokuqala injini esizeni, kutholakala ukuthi imoto iyagxuma ngokusobala, futhi iphutha likhona: ngemuva kokuqala okubandayo, akukho nkinga esigabeni sokungenzi lutho. Ngemva kokuphela kokungenzi lutho, imoto igxumagxuma kukhebhu; Lapho izinga lokushisa lamanzi livamile, imvamisa yokuthuthumela iyancipha. Kuzwakala ngesandla epayipini le-exhaust ukuthi i-exhaust ayilingani ngezikhathi ezithile, "nokusha kweposi" kufana nokuqhuma okuncane kanye ne-exhaust engalingani.
Ukwengeza, sifunde engxoxweni ukuthi imoto yomnikazi isetshenziselwa ukuhamba nokuphuma emsebenzini, nekhilomitha elingu-15 ~ 20km isikhathi ngasinye, futhi akuvamile ukuthi ihambe ngesivinini esikhulu. Uma kulindelwe ukuthi irobhothi lime, kuwumkhuba ukunyathela ibhuleki, isibambo se-shift asiphinde sibuyele egiyeni elithi “n”.
2. Thola iphutha kusukela kokulula kuye kwangaphandle, bese uhlonza iphutha kusukela kokulula kuye kwangaphandle.
(1) Hlola izikhwebu ezine (izizipho) zokuhlanganisa injini, futhi uthole ukuthi kukhona umkhondo wokuthintana okuncane phakathi kwephedi yerabha yento ekhweza kwesokudla kanye nomzimba. Khulisa ukucaciswa ngokungeza amashimu kuzikulufu ezifakwayo, qala imoto ukuze ihlolwe, futhi uzwe sengathi i-jitter ngaphakathi kwekhebhu incishisiwe. Ngemuva kokuhlolwa kokuqala kabusha, i-jitter isabonakala ngemuva kokuphela kokungenzi lutho okuphezulu. Kuhlanganiswe nomkhuba wokukhipha amandla angalingani, kubonakala ukuthi isizathu esiyinhloko akusona ukumiswa, kodwa umsebenzi ongalingani wenjini.
(2) Hlola uhlelo lokulawula ngogesi ngethuluzi lokuxilonga. Ayikho ikhodi yephutha ngesivinini esingenzi lutho; Ukuhlolwa kokugeleza kwedatha kungokulandelayo: ukungena komoya kumayelana ne-11 ~ 13kg / h, ububanzi be-pulse umjovo kaphethiloli ngu-2.6 ~ 3.1ms, 3.1 ~ 3.6ms ngemva kokuvulwa kwesimo somoya, futhi izinga lokushisa lamanzi lingu-82 ℃. Kubonisa ukuthi i-ECU yenjini kanye nesistimu yokulawula i-elekthronikhi yenjini ngokuyisisekelo kujwayelekile.
(3) Hlola uhlelo lokuthungela. Kutholakala ukuthi ulayini we-high-voltage we-cylinder 4 wonakalisiwe futhi ukuvuza kukagesi. Shintshanisa umugqa wamandla kagesi aphezulu wale silinda. Qala injini futhi iphutha alithuthukisiwe kakhulu ngaphansi kwejubane elingenzi lutho. Njengoba umnikazi engashintshile i-spark plug isikhathi eside, iphutha elibangelwa i-spark plug lingazitshwa.
(4) Hlola uhlelo lokuhlinzeka ngophethiloli. Xhuma igeji yokuhlola umfutho wesondlo kumjikelezo kawoyela wesistimu yokunikeza uphethiloli ngesixhumi se-tee. Ngemuva kokuqala injini, ukusheshisa futhi umfutho kawoyela omkhulu ungafinyelela ku-3.5bar. Ngemuva kwehora elingu-1, ukucindezela kwegeji kusahlala ku-2.5bar, okubonisa ukuthi uhlelo lokuhlinzeka ngophethiloli lujwayelekile. Ngesikhathi sokuhlukaniswa nokuhlolwa komjovo kaphethiloli, kutholakala ukuthi i-fuel injector ye-cylinder 2 inesimo esifanayo sokudonsa uwoyela, njengoba kuboniswe kuMfanekiso 1. Faka esikhundleni umjovo we-fuel onephutha we-cylinder 2. Qala injini futhi iphutha lisamile. ayikwazi ukuqedwa.
