Ukusebenza okuyisisekelo kwe-Engine Control Unit (ECU)

Abantu abaningi baye bezwa I-ECU yemoto. Leyo khompyutha encane ephathwa yizo zonke izimoto zesimanje, eqinisekisa ukuthi yonke into isebenza kahle kunoma yisiphi isimo. Ngenxa yalokho, ama-motor angumshini osebenza kahle kakhulu futhi avumelana nezimo ezihlukahlukene, ngaphandle kokuthi umsebenzisi akhathazeke nganoma yini.

Njengezici eziningi zemoto, ubunzima be-ECU kuyehluka kuye ngamamodeli. Nakuba okulula kunawo wonke kuphela okulawula inani likaphethiloli elijovwe emakamelweni avuthayo, abanye futhi banesibopho sokuqhubekela phambili noma ukubambezeleka kokushisa, umzuzu wokuvulwa kwe-valve, ukulawula ukuguquguquka kwe-valve. i-compressor noma i-turbo...

I-ECU iwubuchopho benjini

Ukuze ulawule zonke lezi zakhi, i-ECU kufanele yamukele ulwazi lwezingxenye ezihlukahlukene zenjini kanye nezinsiza zayo. Kubo kukhona inzwa yokugeleza komoya, kusukela esikhundleni sika i-accelerator, lokho kwengcindezi ye i-turboenye ye umfutho wamafutha kanye nezinga lokushisa, the i-crankshaft, njll. Uma noma iyiphi ibona noma yiliphi inani elingavamile, i-ECU ihlelelwe ukuba ibe khona Yenza ngokufanele.

Isibonelo, uma inzwa ye-crankshaft ithola ukuthi injini iphenduka ngaphansi kokuguquguquka okuncane. Ngiqonde ukuthi lizocwila. I-ECU inganikeza umyalo wokujova uphethiloli owengeziwe ukuze ikukhiphe kuleso simo futhi imelane nokuma. Kulezi zimo, kungase futhi kubambezele isikhathi sokuthungela, kuhlehlise inhlansi ye- amapulaki. Lokhu kugwema ubungozi bokugwazwa izinduku zokuxhuma.

Uma i-ECU ithola noma yisiphi isaziso lokho Okuthile okubalulekile enjinini akusebenzi kahle.izothumela isignali ku ikhadi lamaphuzu ukuvula i- isibani sesexwayiso sephutha lenjini. Ngale ndlela, umsebenzisi uzokwazi ukuthi unenkinga futhi uzokwazi ukwenza ngokufanele ukuvimbela iphutha ukuba libe libi kakhulu. Kulezi zimo, i-ECU ingase futhi isebenze i- imodi yokuhluleka ukunciphisa ukuphuka kwengxenye. Okuthile okubonakala ekwehleni okukhulu kokusebenza.

Hlela kabusha noma ushintshe i-ECU

ukuhlela kabusha

Amanye amayunithi abonakala ngokuthi ukwazi ukulungisa ukuvumelanisa nokuziphatha kwemoto ku- izinguquko ezenziwe. Lezi zingasukela ekushintsheni i-turbo kwenye enamakhono angcono, kuya ekushintsheni kwe- i-intercooler komunye okhipha ukushisa kangcono. Zingaphinda zihlelwe kabusha ukuze bafune okwengeziwe ezingxenyeni injini yefekthri enazo.

Nokho, ukuguqulwa kwe-ECU Yinkemba esika nhlangothi zombili. Uma isethwe ngokungalungile, ukusebenza kwemoto kungase kube kubi kakhulu, kungase kungasebenzi nhlobo noma ngisho nokuphuka. Ngakho-ke uma ungcolisa i-ECU, kufanele uqiniseke kakhulu ngalokho okwenzayo. Akuyona i-elementi lapho indlela yokuzama nephutha ngokuvamile isebenza ngayo.

i-chiptuning

Kokunye ukuguqulwa kwezimoto, ukuhlela kabusha i-ECU akwanele. Yingakho abakwenzayo kuwukushintsha ngqo omunye onekhono loku-oda injini lokho abakufunayo. Lokhu kubizwa ngokuthi 'chipping' noma ukulungiswa kwe-chip yenjini esikhundleni sokuhlela kabusha. Into ebijwayele ukwenziwa kuzo zonke izimoto ngoba ama-ECU azo abengahlelwa kabusha. Okwamanje, cishe wonke ama-ECU angashintshwa ngaphakathi kwemikhawulo.
