Sensor ea khatello ea phapang ea koloi ke eng?
Sensor ea khatello e fapaneng ke karolo e nepahetseng ea elektroniki e sebelisetsoang ho lekanya phapang ea khatello lipakeng tsa maemo a mabeli a fapaneng. Ke e 'ngoe ea likarolo tsa bohlokoa tsa ho lemoha likoloing tsa sejoale-joale. Ha e lekanye khatello e felletseng empa e shebane le ho lemoha phapang ea khatello (ΔP = P1 - P2) lipakeng tsa lintlha tse peli tse kang "kou ea ho kenella le kou ea ho ntša mosi" kapa "holimo le tlase", 'me e fetola phapang ena ea khatello hore e be lets'oao la motlakase, leo ebe le fetisetsoang ho yuniti ea taolo ea enjene (ECU) kapa litsamaisong tse ling tsa taolo tse ka har'a sekepe ho fihlela taolo e nepahetseng ea ts'ebetso.
Mesebetsi ea Motheo le Maemo a Ts'ebeliso
Sensor ea khatello e fapaneng e bapala karolo ea "mothapo oa khatello" lits'ebetsong tse ngata tsa bohlokoa tsa likoloi. Ts'ebeliso ea eona ea mantlha e kenyelletsa:
Taolo ea ho ntša mosi o tsoang kantle (taolo ea ho tsosolosa DPF): Ena ke e 'ngoe ea merero ea eona ea mantlha. Sensor e kentsoe lipheletsong tse ka pele le tse ka morao tsa sefe ea likaroloana (DPF), e shebile phapang ea khatello ea mosi o tsoang kantle. Ha likhase tsa khabone li etsa hore phapang ea khatello e fete moeli, ECU e tla qala "lenaneo la ho tsosolosa", e eketsa mocheso oa mosi ho chesa likhase tsa khabone ho qoba ho koaloa, tahlehelo ea matla le ho ntša mosi.
Ntlafatso ea karolelano ea ho kenngoa ha enjene le ea moea-mafura: Litsamaisong tse ling, e sebelisoa ho lekanya phapang ea khatello pakeng tsa manifold ea ho kenngoa ha enjene ka mor'a throttle le sepakapaka kapa liphaephe tse itseng. Ha e kopantsoe le lintlha tse ling tsa sensor, e bala ka tsela e sa tobang bophahamo ba ho kenngoa ha enjene, e thusa ECU ho laola ka nepo bophahamo ba ho kenngoa ha mafura le nako ea ho hotetsa, ho ntlafatsa katleho ea ho tuka ha enjene.
Tlhokomelo ea sistimi ea mafura: Lienjineng tsa diesel tsa seporo tse nang le khatello e phahameng kapa litsamaisong tsa ente ea peterole e tobileng, e beha leihlo phapang ea khatello maemong a fapaneng a phaephe ea mafura, e fana ka maikutlo a boemo ba millisecond ho ECU, e fihlella taolo e nepahetseng ea bophahamo ba ente ea mafura (ka phoso e ka hare ho ±0.02ml), e leka-lekanya matla le tšebeliso ea mafura.
Sistimi ea ho potoloha ha khase ea mosi (EGR): E kentsoe lipheletsong tsa valve ea EGR kapa cooler ea EGR, e lekanya phapang ea khatello ho fumana hore na valve ea EGR e butsoe hakae, hore na phaephe e koetsoe kapa ea lutla, e netefatsa bophahamo bo nepahetseng ba ho potoloha ha khase ea EGR le ho fokotsa ka katleho mesi ea naetrojene oxide.
Sistimi ea taolo ea mouoane oa mafura (EVAP): E sebelisetsoa ho fumana hore na ho na le ho lutla kapa ho thibana ha liphaephe tsa sistimi ea mafura. Sistimi e baka phapang e nyane ea khatello, 'me sensor e lemoha phetoho. Haeba e sa fihlelle litebello, sistimi e ahloloa hore e na le phoso 'me leseli la phoso lea bonesoa.
Sistimi ea ho emisa moea: Ka mehlala ea maemo a holimo, e shebella phapang ea khatello lipakeng tsa mahlakore a mabeli a seponche sa moea, e sebelisana le khomphutha e ka hare ho sekepe ho lokisa mongobo metsotsoana e meng le e meng e seng mekae, e ntlafatsa haholo botsitso ba leeto la koloi litseleng tse nang le likoti.
Tlhaloso e Khutšoanyane ea Molao-motheo oa Mosebetsi
Karolo ea mantlha ea sensor ea khatello e fapaneng ke diaphragm e bonolo e arolang sensor hore e be pheletso e nang le khatello e phahameng (H) le pheletso e nang le khatello e tlase (L). Ha khatello e lekantsoeng P1 le P2 li sebelisoa lipheletsong ka bobeli, diaphragm e fetoha le phetoho e nyane ka lebaka la phapang ea khatello. Phetoho ena e bonoa 'me e fetoloa ke mokhoa oa phetoho ea ka hare (joalo ka liphetoho tsa khanyetso ho li-gauge tsa khatello, liphetoho boleng ba capacitance, kapa phello ea piezoelectric) hore e be lets'oao la motlakase, le ntseng le eketseha le ho lefshoa ke potoloho, ebe le hlahisoa e le motlakase o tloaelehileng, oa hona joale, kapa lets'oao la dijithale bakeng sa ECU ho e sebelisa.
Tšusumetso ea Liphoso
Haeba sensor ea khatello e fapaneng e senyehile kapa lets'oao le sa nepahala, ECU e tla fumana data e fosahetseng ea phapang ea khatello, e ka lebisang ho:
Lebone la phoso ea enjene lea bonesa
Torque ea enjene e lekanyelitsoe, matla aa fokotseha
Palo ea bophahamo ba ente ea mafura ha e nepahale, e fellang ka keketseho ea tšebeliso ea mafura, khaello ea matla, kapa tlhahiso ea mosi
Lenaneo la ho tsosolosa DPF ha lea tloaeleha, le ka baka ho koaleha ho hoholo ha mmele
Sistimi ea EGR e sebetsa ka mokhoa o sa tloaelehang, e amang botsitso ba tlhahiso le ho chesa
Qetellong, leha sensor ea khatello e fapaneng e le nyane ka boholo, ke karolo ea bohlokoa e netefatsang ts'ebetso, bokhoni, ho latela maemo a mosi o tsoang, le polokeho ea likoloi.
