Mosebetsi oa sensor ea khatello ea ho kena ha koloi
Mesebetsi ea mantlha ea sensor ea khatello ea moea ea likoloi e kenyelletsa lintlha tse latelang:
Fana ka letshwao la mojaro wa enjene: Sensor ya kgatello ya ho kenella e fa ECU (Yuniti ya taolo ya enjene) letshwao la mojaro wa enjene ka ho lekanya phetoho ya kgatello ho manifold ya ho kenella. Matshwao ana a thusa ECU ho laola bophara ba pulse ya enjene le ho buleha ha throttle ka nepo ho ntlafatsa tshebetso ya enjene le ho boloka mafura.
Taolo ea ho kenngoa ha mafura le nako ea ho hotetsa: Li-sensor li fetola liphetoho tsa khatello ho intake manifold hore e be matšoao a motlakase bakeng sa ECU ho lokisa ente ea mafura le nako ea ho hotetsa Angle. Ha mojaro oa enjene o eketseha, khatello ho intake manifold ea fokotseha, lets'oao la tlhahiso ea sensor lea eketseha, 'me ECU e eketsa bongata ba ente ea mafura le ho liehisa Angle ea pele ea ho hotetsa. Ho seng joalo, ente ea mafura e tla fokotseha 'me ho hotetsa ho tla ba ho tsoetseng pele .
Fetola nako ea ho buloa ha valve ea ho kenella le ente ea mafura: Enjeneng e nang le sistimi ea taolo ea li-valve tsa elektroniki, sensor ea khatello ea ho kenella e lemoha phetoho ea khatello phaepheng ea ho kenella 'me e bala ka nepo bophahamo ba moea ka har'a silindara e' ngoe le e 'ngoe ho lokisa nako ea ho buloa ha valve ea ho kenella le bophahamo ba ente ea mafura. Sena se thusa ho ntlafatsa bokhoni le tlhahiso ea matla ea enjene.
Sireletsa enjene: Sensor ea khatello ea ho kena e ka boela ea lemoha maemo a sa tloaelehang a ts'ebetso ea enjene, joalo ka liphetoho tse sa tloaelehang tsa khatello, 'me ea romela matšoao tsamaisong ea taolo ho sireletsa enjene. Sena se thusa ho thibela tšenyo ea enjene ka lebaka la ho jara boima ba 'mele kapa mathata a mang.
Molao-motheo oa ho sebetsa: Sensor ea khatello ea ho kenella hangata e hokahantsoe le intake manifold ka tube ea vacuum 'me e utloa phetoho ea vacuum ho intake manifold. Ha lebelo la enjene le mojaro li fetoha, khatello ho intake manifold e tla fetoha, 'me khanyetso e ka hare ho sensor le eona e tla fetoha ka ho loketseng, kahoo e ntša lets'oao la motlakase. Letšoao lena le amoheloa ke ECU 'me le sebelisoa ho fetola ente ea mafura le nako ea ho hotetsa .
Tšusumetso ea phoso: Haeba sensor ea khatello ea ho kena e senyehile, e ka lebisa lebelong le sa tsitsang la ho se sebetse, ho potlaka ho fokolang, bothata ba ho qala, tšebeliso e eketsehileng ea mafura le mathata a mang a koloi. Ka nako e ts'oanang, lebone la phoso ea enjene le tla bonesoa, 'me khoutu ea phoso e tsamaellanang le eona e tla bolokoa.
Ka hona, tlhahlobo le tlhokomelo ea kamehla ea sensor ea khatello ea ho kena ke ea bohlokoa ho netefatsa ts'ebetso e tloaelehileng ea koloi.
Sensor ea Khatello e sa Feleng ea Manifold (MAP) ke karolo ea bohlokoa enjeneng ea likoloi e hlahlobang liphetoho tsa khatello ho intake manifold mme e fetola liphetoho tsena hore e be matšoao a motlakase bakeng sa taolo e nepahetseng ke yuniti ea taolo ea elektroniki ea enjene (ECU). Sensor ea khatello ea intake e hokahantsoe le intake manifold ka tube ea vacuum 'me e ka utloa phetoho ea vacuum ho intake manifold. Ka lebelo le mojaro o fapaneng oa enjene, khanyetso ka hare ho sensor e tla fetoha, e tla fetoloa lets'oao la motlakase bakeng sa ECU ho lokisa bongata ba ente ea mafura le nako ea ho hotetsa .
Molao-motheo oa ho sebetsa
Molao-motheo oa ts'ebetso oa sensor ea khatello ea ho kenella o ipapisitse le phetoho ea khanyetso e bakoang ke phetoho ea khatello. Nka sensor ea khatello ea mofuta oa varistor e le mohlala, karolo ea eona ea mantlha ke diaphragm ea silicon e entsoeng ka phello ea piezoresistive ea semiconductor. Ha khatello ea intake manifold e sebetsa holim'a diaphragm ea silicon, diaphragm e tla fetoha sebopeho, e leng se fellang ka phetoho boleng ba eona ba khanyetso. Phetoho ena e fetoloa lets'oao la motlakase, le ntseng le holisoa ebe le fetisetsoa ho ECU. Ho ipapisitsoe le motlakase oa lets'oao o amohetsoeng, ECU e laola ente ea motheo ea mafura ka nepo ho lumellana le litlhoko tse fapaneng tsa ho khanna .
Mefuta le lits'ebetso
Ho na le mefuta e mengata ea li-sensor tsa khatello ea ho kena, tse tloaelehileng ke semiconductor varistor , vacuum bellows le capacitive . Har'a tsona, semiconductor varistor e sebelisoa haholo tsamaisong ea ente ea mofuta oa D ka lebaka la melemo ea eona ea karabelo e potlakileng, ho nepahala ho hoholo, boholo bo bonyenyane le ho kenngoa ho tenyetsehang. Sensor ea capacitive e sebelisa diaphragm ho etsa karolo e utloang khatello e nang le boleng ba capacitance bo fetohang, 'me e fetola phetoho ea khatello hore e be lets'oao la motlakase ka ho lekanya potoloho.
Tlhokomelo le tlhahlobo ea liphoso
Tlhahlobo ea phoso ea sensor ea khatello ea ho kena hangata e kenyelletsa ho hlahloba hore na lets'oao la eona la tlhahiso le ka har'a moeli o tloaelehileng. Haeba lets'oao la tlhahiso ea sensor le sa tloaeleha, ts'ebetso ea enjene e ka 'na ea fokotseha kapa ea se tsitse. Nakong ea tlhokomelo, hlahloba nako le nako khokahano le ho koaloa ha sensor ho netefatsa hore e sebetsa hantle.
Haeba o batla ho tseba ho eketsehileng, tsoela pele ho bala lihlooho tse ling sebakeng sena sa marang-rang!
Ka kopo re letsetse haeba o hloka dihlahiswa tse jwalo.
