Imephu kanye ne-e-injection, ubude bempilo obuntathu

Umshini wokugcwalisa i-carburizing, usebenza kanjani?

Isilinganiso

Ukunemba komthamo kungamandla omjovo nokuthi yini ewuhlukanisa ne-carburetor. Ngempela, kuthatha cishe amagremu angu-14,5 omoya ukushisa igremu elilodwa likaphethiloli, ngoba ngokungafani nophethiloli we-diesel, injini kaphethiloli isebenza ngokucebile njalo. Lokhu kusho ukuthi lapho ukugeleza komoya kwanda noma kuncipha, ukugeleza kukaphethiloli kufanele kushintshwe. Uma kungenjalo, izimo zokuvutha azifinyelelwanga futhi i-spark plug ngeke iwuthungele ingxube. Ngaphezu kwalokho, ukuze umlilo uphelele, okunciphisa ukukhishwa kwezinto ezingcolile, kuyadingeka ukuthi uhlale useduze kakhulu nengxenye esiyibonisile. Lokhu kuyiqiniso nakakhulu ekwelashweni kwe-catalytic, okusebenza kuphela ebangeni elincane kakhulu lokunotha, okungenakwenzeka ukugcinwa nge-carburetor, ngaphandle kwalokho kungasebenzi. Zonke lezi zizathu zichaza ukunyamalala kwe-carburetor ngokuthanda umjovo.

Vula noma uvale iluphu?

Ukuveza isilinganiso sobuningi bomoya / uphethiloli akujabulisi neze, kodwa uma sicabanga ukuthi sinegesi, ngakolunye uhlangothi, uketshezi, ngakolunye, nalokho esikusho ngevolumu, khona-ke sithola ukuthi sidinga amalitha ayi-10 omoya ukuze shisa ilitha likaphethiloli! Ekuphileni kwansuku zonke, lokhu kuchaza ukubaluleka kwesisefo somoya esihlanzekile, esibona kalula amalitha ayi-000 omoya edlula kuso ukuze ishise ithangi eligcwele! Kodwa ukuminyana komoya akushintshi. Kuyahlukahluka lapho kushisa noma kubanda, kunomswakama noma komile, noma lapho usendaweni ephakeme noma olwandle. Ukuze kuhlangatshezwane nalo mehluko, kusetshenziswa izinzwa eziguqula ulwazi lube amasignali kagesi asukela ku-100 kuye ku-000 volts. Lokhu kuthinta izinga lokushisa lomoya, kodwa futhi nezinga lokushisa elipholile, umfutho womkhathi, noma ebhokisini lomoya, njll. Izinzwa zibuye zenzelwe ukuxhumana nezidingo zomshayeli, aziveza ngesibambo se-accelerator. Le ndima idluliselwe ku-TPS edumile "(i-Throttle Position Sensor" noma inzwa ye-butterfly position ka-Moliere).

Ngempela, imijovo eminingi namuhla isebenza ngokwesu le-"α / N", α iyi-engeli yokuvula uvemvane futhi N ijubane lenjini. Ngakho, kuzo zonke izimo, ikhompyutha iba nenkumbulo yenani likaphethiloli okufanele iyijove. Yile nkumbulo ebizwa ngokuthi imephu noma ukwenza imephu. Lapho ikhompuyutha inamandla kakhulu, amaphuzu amaningi enawo ekudwebeni futhi ikwazi ukuzivumelanisa kahle nezimo ezihlukahlukene (ingcindezi, ukushintshashintsha kwezinga lokushisa, njll.). Ngempela, akukho neyodwa, kodwa amamephu abhalisa isikhathi somjovo ngokuhambisana nemingcele ye-α / N yokushisa kwenjini X, izinga lokushisa lomoya Y nokucindezela Z. Ngaso sonke isikhathi lapho ipharamitha ishintshwa, ukuqhathanisa okusha noma okungenani ukulungiswa kufanele kushintshwe. emisiwe.

Ngaphansi kokugadwa.

Ukuqinisekisa ukugcwala kwe-carburation okuhle kakhulu futhi ngaphakathi kwebanga elihambisana nokusebenza kwe-catalyst, ama-lambda probes akala izinga le-oxygen kugesi ephumayo. Uma kunomoya-mpilo omningi, kusho ukuthi ingxube incane kakhulu, futhi empeleni umshini wokubala kufanele ucebise ingxube. Uma umoya-mpilo ungasekho, ingxube inothe kakhulu futhi isibali siphelile. Lolu hlelo lokulawula ngemva kokugijima lubizwa ngokuthi "iluphu evaliwe". Ezinjinini (zemoto) ezingcoliswe kakhulu, sihlola ngisho nokusebenza okulungile kwe-catalyst sisebenzisa i-lambda probe endaweni yokungena kanye nenye endaweni yokuphuma, uhlobo lweluphu kuluphu. Kodwa ngaphansi kwezimo ezithile, ulwazi mayelana ne-probe alusetshenziswa. Ngakho-ke, kubanda, lapho i-catalyst ingakasebenzi futhi ingxube kufanele inothiswe ukuze kunxephezele ukufiphala kukaphethiloli ezindongeni ezibandayo zenjini, siyakhululwa kuma-lambda probe. Imizamo iyenziwa njengengxenye yezindinganiso zokulawula ukungcola ukuze kuncishiswe lesi sikhathi soshintsho ngisho nokushisisa ama-probe ngokumelana nogesi okwakhelwe ngaphakathi ukuze ziphendule ngokushesha futhi zinganciphisi. Kodwa lapho ushayela ngemithwalo ephezulu (amagesi aluhlaza) lapho ufaka khona "i-loop evulekile", ukhohlwe ngama-probes we-lambda. Ngempela, ngaphansi kwalezi zimo, ezingaphezu kokulawulwa kokuhlolwa okujwayelekile, kokubili ukusebenza nokugcinwa kwenjini kuyafunwa. Eqinisweni, isilinganiso somoya / sikaphethiloli asisekho i-14,5 / 1, kodwa sehla siye cishe ku-13/1. Siyazicebisa ukuze siwine amahhashi siphinde sipholise injini ngoba siyazi ukuthi izingxube ezimbi ziyashisisa izinjini futhi zibe sengozini yokuzilimaza. Ngakho-ke uma ushayela ngokushesha, udla kakhulu, kodwa futhi ungcolisa kakhulu ngokubuka kwekhwalithi.

Ama-injection kanye nama-mechanics

Ukuze konke kusebenze, akwanele ukuba nezinzwa kanye ne-calculator ... Kudinga futhi uphethiloli! Okungcono kunalokho, udinga uphethiloli onomfutho. Ngakho-ke, injini yomjovo ithola iphampu kaphethiloli kagesi, ngokuvamile ehlala ethangini, enesistimu yokulinganisa. Unikeza ama-injection amafutha. Aqukethe inaliti (inaliti) ezungezwe ikhoyili kagesi. Njengoba umshini wokubala uphakela ikhoyili, inaliti iphakanyiswa yizibuthe, ikhiphe uphethiloli ocindezelweyo, ofuthwa ezinhlobonhlobo. Ngempela, emabhayisikili ethu sisebenzisa umjovo "ongaqondile" ku-multifold noma ebhokisini lomoya. Imoto isebenzisa umjovo "oqondile", lapho uphethiloli ujova ngengcindezi ephezulu endaweni evuthayo. Lokhu kunciphisa ukusetshenziswa kukaphethiloli, kodwa noma iyiphi indondo ine-drawback yayo, umjovo oqondile uphumelela ukukhipha izinhlayiya ezinhle enjinini kaphethiloli. Ngokusemandleni ethu, asiqhubeke nomjovo wethu omuhle ongaqondile. Ngaphezu kwalokho, isistimu ingathuthukiswa, njengoba kuboniswe esihlokweni sethu sakamuva esithi VALIWE ON ...

Okungcono kodwa kunzima

Imijovo, izinzwa, amayunithi okulawula, iphampu yegesi, ama-probe, imijovo yenza izithuthuthu zethu zibize kakhulu futhi zibe nzima. Kodwa futhi kusivulela amathuba amaningi. Ngaphezu kwalokho, sikhuluma ngemijovo, kodwa phawula ukuthi konke lokhu kubuye kuhlanganiswe nokuthungela, inqubekelaphambili yayo futhi iyahlukahluka kuye ngokuthi isibonisi esihlotshaniswa nomjovo.

Ukusebenza kwezithuthuthu kuyanda, ukusetshenziswa kuyehla. Akusekho ukulungisa, amabhayisikili angasekeli intaba, njll. Kusukela manje kuqhubeke konke kulawulwa ngokuzenzakalelayo, ngaphandle kokungenelela komshayeli wendiza noma umakhenikha. Lokhu kuyinto enhle, umuntu angase athi, ngoba awukwazi ukuthinta lutho, noma cishe noma yini, ngaphandle kwemishini ye-elekthronikhi eyanele. Kodwa ngaphezu kwakho konke, umjovo usivulela iminyango emisha, ikakhulukazi ukufika kokulawula ukudonsa. Ukumodela amandla enjini manje kuwumdlalo wengane. Buza abashayeli abangodokotela abajwayelekile ukuthi bacabangani futhi uma becabanga ukuthi "bekungcono ngaphambilini" !!
