Ho Utloisisa Likarolo ho Mekhoa ea EFI
Indasteri ea likoloi ea sejoale-joale e bile le tsoelo-pele e kholo lilemong tse mashome tse fetileng, 'me e 'ngoe ea lintlafatso tsa bohlokoa ka ho fetisisa e bile ho hlaha ha litsamaiso tsa Electronic Fuel Injection (EFI). Litsamaiso tsena li fetotse tsela eo lienjene li sebetsang ka eona, li fana ka ts'ebetso e ntlafetseng, li fokolitse mosi o tsoang moeeng, le motsoako o ntlafalitsoeng haholoanyane oa mafura ho tloha moeeng. Ho ananela le ho utloisisa boqhetseke bo ka morao ho litsamaiso tsa EFI, ho bohlokoa ho hlahloba likarolo tsa tsona tsa mantlha le karolo eo e 'ngoe le e 'ngoe e e bapalang ho netefatseng ts'ebetso e se nang sekoli ea enjene.
1. Yuniti ea Taolo ea Enjene (ECU)
Bohareng ba sistimi e 'ngoe le e 'ngoe ea EFI ho na le Yuniti ea Taolo ea Enjene (ECU). Hangata e bitsoang boko ba enjene, ECU e laola ts'ebetso ea ho kenya le liparamente tse fapaneng tsa enjene ho ntlafatsa ts'ebetso le bokgabane. E amohela tlhahiso ho tsoa ho li-sensor tse ngata ho pholletsa le enjene, e sebetsana le data e sebelisa li-algorithms tsa eona tse hlophisitsoeng esale pele, ebe e romela litaelo ho li-injector tsa mafura le li-actuator tse ling. Ha e le hantle, ECU e ikarabella bakeng sa ho fumana palo e nepahetseng ea mafura le nako ea ho kenya ho latela maemo a nako ea sebele.
Mesebetsi ea Bohlokoa:
– Ho beha leihlo di-sensor tsa enjene ho bokella tlhahisoleseding.
– Ho bala motsoako o motle oa mafura le nako ea ho hotetsa.
– Ho laola di-injector tsa mafura ho fana ka palo e nepahetseng ya mafura.
– Ho lokisa diparamitha ho latela di-input tsa mokhanni le maemo a tikoloho.
2. Li-Injector tsa Mafura
Li-injector tsa mafura ke likarolo tse ikarabellang ka ho toba bakeng sa ho kenya mafura ka phapusing ea ho tuka. Li sebetsa ka ho fafatsa moholi o monyane oa mafura tlas'a khatello e phahameng, ho netefatsa kabo e lekanang le ho tuka ka botlalo. Li-injector tsa sejoale-joale li etselitsoe ho nepahala, ka bokhoni ba ho fana ka atomization ea mafura khatellong e phahameng haholo, ka linako tse ling e fetang 2000 psi.
Features bohlokoa:
– Ho nepahala ho hoholo ho laola bongata ba mafura a kentsweng.
– Karabelo e potlakileng litaelong tse tsoang ho ECU.
– Bokhoni ba ho sebetsa tlas'a khatello e phahameng le ho mamella maemo a feteletseng a enjene.
3. Pompo ea Mafura le Taolo ea Khatello ea Mafura
Pompo ea mafura e bapala karolo ea bohlokoa ho netefatseng hore li-injector li lula li fana ka mafura. Hangata e fumaneha ka har'a tanka ea mafura 'me e ikarabella bakeng sa ho isa mafura ho li-injector ka khatello e phahameng. E sebetsa hammoho le pompo ea mafura ke molaoli oa khatello ea mafura, ea bolokang khatello e sa khaotseng seporong sa mafura, a netefatsa hore li-injector li fumana mafura ka khatello e nepahetseng e hlokahalang bakeng sa ho etsa hore atomization e sebetse hantle.
Litšobotsi tsa bohlokoa:
– Phano e tsitsitseng ya peterole kgatellong e phahameng.
– Ho tšepahala ho qoba tlala ea mafura, haholo-holo tlas'a meroalo e mengata ea enjene.
– Bokhoni ba ho boloka khatello e tsitsitseng ho sa tsotelehe litlhoko tse fapaneng tsa enjene.
4. Sensor ea Phallo ea Moea o Monyenyane (MAF) le Sensor ea Khatello e sa Fetoheng (MAP)
Sensor ea Mass Air Flow le sensor ea Manifold Absolute Pressure li bohlokoa bakeng sa litekanyo tse nepahetseng tsa moea. Sensor ea MAF e lekanya bongata ba moea o kenang enjeneng, e leng se thusang ECU ho fumana bongata bo hlokahalang ba mafura bakeng sa karolelano e ntle ea moea le mafura. Sensor ea MAP, ka lehlakoreng le leng, e lekanya khatello e ka har'a manifold, e fana ka lintlha tse ling mabapi le mojaro oa enjene.
Bohlokoa le Ts'ebetso:
– Sensor ea MAF e netefatsa tekanyo e nepahetseng ea moea bakeng sa taolo ea karolelano ea mafura.
– Sensor ea MAP e fana ka lintlha tsa bohlokoa mabapi le mojaro oa enjene le khatello ea sepakapaka.
– Li-sensor ka bobeli li kenya letsoho ho lekanyeng ka nepo ha enjene, e leng se lebisang ts'ebetsong le katlehong e ntle.
5. Li-sensor tsa Oksijene (Li-sensor tsa O2)
Li-sensor tsa oksijene, tseo hangata li beoang tsamaisong ea mosi, li lekanya bongata ba oksijene likhaseng tsa mosi. Tlhahisoleseling ena e thusa ECU ho fetola mokhoa oa ho kenya mafura ho boloka motsoako o motle oa moea le mafura, ho netefatsa hore enjene e sebetsa ka katleho kamoo ho ka khonehang ha e ntse e hlahisa mesi e fokolang. Likoloi tsa sejoale-joale hangata li na le li-sensor tse peli kapa ho feta tsa oksijene - e 'ngoe pele ho sesebelisoa sa ho fetola motlakase le e 'ngoe kamora - ho beha leihlo le ho laola mesi e tsoang ka katleho haholoanyane.
Mesebetsi:
– Ho beha leihlo likhase tse ntšang mosi ho fana ka maikutlo a hore na ho lokisoa motsoako oa mafura le moea joang.
– Ho thusa ho fihlella le ho boloka ho tuka ha stoichiometric.
– Ho fokotsa mesi e kotsi ka ho netefatsa ho tuka hantle.
6. Sensor ea Boemo ba Throttle (TPS)
Sensor ea Boemo ba Throttle e bohlokoa bakeng sa ho beha leihlo boemo ba valve ea throttle. E fana ka data ea nako ea sebele ho ECU mabapi le hore na throttle e bulehile hakae, e leng se lekanang ka ho toba le tlhoko ea motlakase ea mokhanni. Lintlha tsena, hammoho le tse tsoang ho li-sensor tse ling, li thusa ECU ho fumana hore na peterole e nepahetseng e ka kenngoa neng kapa neng.
mesebetsi:
– Ho fana ka maikutlo a hang-hang ho ECU mabapi le tlhoko ea motlakase ea mokhanni.
– Ho thusa tsamaisong e nepahetseng ea mafura le ho a isa ka phanong.
– Ho fokotsa ho lieha le ho netefatsa taolo ea throttle e arabelang.
7. Sensor ea Mocheso oa Moea o Kenang (IAT)
Sensor ea Mocheso oa Moea o Kenang e bapala karolo ea bohlokoa ho thuseng ECU ho utloisisa mocheso oa moea o kenang enjeneng. Boima ba moea boa fetoha ho latela mocheso, 'me ECU e sebelisa tlhahisoleseling ena ho fetola nako le bongata ba ho kenngoa ha mafura bakeng sa ho chesa hantle.
Bohlokoa:
– Ho thusa ho baleng ka nepo tekanyo ea moea le mafura.
– Ho thusa enjene ho ikamahanya le maemo a mocheso a fapaneng.
– Ho kenya letsoho tshebetsong e sebetsang hantle ya enjene, haholoholo maemong a feteletseng.
8. Sensor ea Mocheso o Pholisang (CTS)
Sensor ea Mocheso o Pholileng e fana ka tlhahisoleseling ea bohlokoa mabapi le mocheso oa hona joale oa enjene. Ha enjene e ntse e futhumala, litlhoko tsa eona tsa mafura le nako lia fetoha, 'me CTS e lumella ECU ho etsa liphetoho tse hlokahalang ho boloka ts'ebetso le bokhoni bo botle.
Senotlolo Lintlha:
– Ho beha leihlo mocheso oa enjene bakeng sa liphetoho tsa ts'ebetso.
– Ho thusa maemong a qalang ka mokhoa o bataletseng bakeng sa taolo e ntlafetseng ya mafura.
– Ho netefatsa tšireletso ea ho chesa haholo ka ho beha leihlo mocheso ka nako ea sebele.
fihlela qeto e
Mekhoa ea ho kenya mafura ka elektroniki e emela tsoelo-pele e ikhethang theknolojing ea likoloi, e kopanyang boenjiniere bo nepahetseng le lisebelisoa tsa elektroniki tse rarahaneng. Ho utloisisa likarolo tsa litsamaiso tsa EFI ho fana ka leseli la hore na lienjene tsa sejoale-joale li fihlella katleho e phahameng joang, li fokotsa mosi o tsoang ka har'a motlakase le ts'ebetso e phahameng. Karolo ka 'ngoe, ho tloha ho ECU ho ea ho li-sensor, e bapala karolo ea bohlokoa, e sebetsa ka kutloano ho fana ka motsoako o motle oa mafura le moea tlas'a maemo ohle a ho khanna.
Bakeng sa motho ea ratang likoloi kapa mong'a koloi ea ratang ho tseba, kananelo ea litsamaiso tsa EFI ha e khothalletse feela kutloisiso e kholoanyane ea likoloi tsa bona empa hape e totobatsa tsoelo-pele e makatsang boenjiniere ba likoloi e tsoelang pele ho bopa bokamoso ba lipalangoang.
