Sensor ea boemo ba throttleKe likarolo tsa bohlokoa lienjineng tsa sejoale-joale tsa likoloi, tse fanang ka tlhaiso-leseling e bohlokoa mabapi le boemo ba throttle ho Yuniti ea Taolo ea Enjine (ECU).Li-Sensors tsa Boemo ba Throttle, Mesebetsi ea Tsona, Mefuta, Melao-motheo ea Ts'ebetso, Likopo le Liphephetso.TPS e bapala karolo ea bohlokoa ho boloka ts'ebetso ea enjine, ho ntlafatsa ts'ebetso ea mafura le ho fokotsa likhase.Ha theknoloji ea likoloi e ntse e tsoela pele, TPS e ntse e le eona ntho ea bohlokoa molemong oa ho ntlafatsa ts'ebetso ea likoloi le ho boloka tikoloho.

Throttle Position Sensors (TPS) ke karolo ea bohlokoa ea litsamaiso tsa ente ea mafura tsa elektroniki tse sebelisoang lienjineng tse ngata tsa sejoale-joale tse tukang ka hare.E hlokomela boemo ba poleiti ea throttle mme e fetisetsa tlhahisoleseding ena ho Engine Control Unit (ECU).ECU e sebelisa lintlha tsa TPS ho bala motsoako o nepahetseng oa mafura a moea, nako ea ho khantša le moroalo oa enjene, ho netefatsa ts'ebetso e ntle ka ho fetisisa ea enjene tlas'a maemo a fapaneng a ho khanna.Ho na le mefuta e 'meli e meholo ea li-sensor tsa boemo ba throttle: potentiometric le e sa amaneng.

TPS e ka khonehang e na le ntho e hanyetsang le letsoho la ho hlakola le hokahaneng le throttle shaft, ha letlapa la throttle le buloa kapa le koetsoe, letsoho la wiper le tsamaea hammoho le ntho e hanyetsang, ho fetola khanyetso le ho hlahisa tekano le letšoao la motlakase oa boemo ba throttle.Joale motlakase ona oa analoge o romeloa ho ECU bakeng sa ho sebetsa.TPS e sa amaneng le batho, e tsejoang hape e le Hall Effect TPS, e sebelisa molao-motheo oa Hall Effect ho lekanya boemo ba throttle.E na le makenete e hoketsoeng ho throttle shaft le sensor ea Hall effect.

Ha makenete e ntse e potoloha le throttle shaft, e hlahisa matla a khoheli, a bonoang ke sensor ea Hall effect, a hlahisa lets'oao la motlakase.Ha ho bapisoa le TPS ea potentiometric, TPS e sa amaneng le eona e fana ka ts'epo e phahameng le ho tšoarella hobane ha ho na likarolo tsa mochini tse amanang ka kotloloho le throttle shaft.Molao-motheo oa ts'ebetso oa TPS ke ho fetola motsamao oa mochini oa valve ea throttle hore e be pontšo ea motlakase eo sesebelisoa sa taolo ea elektronike se ka se bonang.

Ha throttle plate e ntse e potoloha, letsoho la "wiper" holim'a potentiometer TPS le tsamaea haufi le mokhoa oa ho hanyetsa, ho fetola phallo ea motlakase, 'me ha throttle e koetsoe, khanyetso e ka holimo ho eona, e fella ka pontšo e tlaase ea motlakase.Ha throttle e bula, khanyetso ea fokotseha, e leng se etsang hore lets'oao la motlakase le phahame ka ho lekana.Setsi sa taolo ea elektroniki se fetolela lets'oao lena la motlakase ho tseba boemo ba throttle le ho lokisa liparamente tsa enjine ka nepo.Ho TPS e sa amaneng, makenete e potolohang e hlahisa matla a khoheli a fetohang, a bonoang ke sensor ea Hall-effect.

Sena se hlahisa lets'oao la phallo ea motlakase le tsamaellanang le boemo ba valve ea throttle, ha ho buloa poleiti ea throttle, matla a matla a khoheli a bonoang ke phetoho ea sensor ea holo, karolo ea taolo ea elektroniki e sebetsa lets'oao lena ho laola ts'ebetso ea enjene.Li-sensor tsa boemo ba Throttle li fumaneha ka har'a lienjineri tse fapaneng tse tukang ka hare, ho kenyeletsoa likoloi, lithuthuthu, liketsoana le likoloi tse ling.Ke likarolo tsa bohlokoa tsa sistimi ea ente ea mafura ea elektroniki le sistimi ea taolo ea elektroniki, e nolofalletsang taolo e nepahetseng ea ts'ebetso ea enjene le mesi.

Motsoako oa li-sensor tsa boemo ba throttle o tlisa melemo e mengata ho litsamaiso tsa sejoale-joale tsa likoloi.Sensor ea boemo ba throttle e nolofalletsa karolo ea taolo ea elektronike ho ntlafatsa motsoako oa mafura a moea le nako ea ho khantša bakeng sa maemo a fapaneng a ho khanna ka ho fana ka lintlha tse nepahetseng tsa boemo ba throttle, kahoo ka katleho Ho thusa ho ntlafatsa tshebetso ea enjene.Ka ho laola hantle karo-karolelano ea mafura a moea, TPS e thusa ho ntlafatsa ts'ebetso ea mafura, e bakang tšebeliso e tlase ea mafura le mesi.

Bohareng ba ts'ebetso ea eona, sensor ea boemo ba throttle e lemoha boemo ba poleiti ea throttle, e bulang kapa e koalang ha mokhanni a hatella pedal ea khase, ho laola boholo ba moea o kenang ka makhetlo a mangata a enjene.Sensor ea boemo ba throttle e kentsoeng 'meleng oa throttle kapa e khomaretsoeng ho throttle shaft e latela hantle motsamao oa throttle blade ebe e e fetolela ho letšoao la motlakase, hangata motlakase kapa boleng ba ho hanyetsa.Joale letšoao lena le romelloa ho ECU, e sebelisang data ho etsa liphetoho tsa nako ea sebele ho li-parameter tsa enjene.

E 'ngoe ea mesebetsi ea bohlokoa ea TPS ke ho thusa ECU ho tseba hore na enjene e kae.Ka ho hokahanya boemo ba throttle le likarolo tse ling tsa enjene joalo ka lebelo la enjine (RPM) le khatello e matla ea ho kenella (MAP), ECU e ka bala mojaro oa enjene ka nepo.Lintlha tsa palo ea enjine li bohlokoa ho fumana nako e hlokahalang ea ente ea mafura, nako ea ho tima le likarolo tse ling tse amanang le ts'ebetso.Tlhahisoleseding ena e nolofalletsa karolo ea taolo ea elektronike ho ntlafatsa motsoako oa mafura a moea.

Likoloing tsa sejoale-joale tse nang le Electronic Throttle Control (ETC), TPS e thusa ho tsamaisa puisano lipakeng tsa mokhanni oa pedal pedal le motsamao oa enjene.Ka mokhoa o tloaelehileng oa throttle, pedal ea khase e kopantsoe ka mochine ho pedal ea khase ka mohala.Leha ho le joalo, tsamaisong ea ETC, valve ea throttle e laoloa ka elektronike ke ECU ho latela lintlha tsa TPS.Theknoloji ena e fana ka ho nepahala le karabelo e kholoanyane, e matlafatsa boiphihlelo ba ho khanna ka kakaretso le polokeho.

Karolo e 'ngoe ea bohlokoa ea TPS ke karolo ea eona tlhahlobong ea enjene, yuniti ea taolo ea elektroniki e lula e lekola lets'oao la TPS le ho le bapisa le lipalo tse ling tsa sensor ea enjine.Phapang leha e le efe kapa phoso e teng ho data ea TPS e baka khoutu ea bothata ba ho hlahloba (DTC) mme e khantša leseli la "check engine" phanele ea lisebelisoa.Sena se thusa mechini ho tseba mathata a ka bang teng mabapi le sistimi ea throttle kapa likarolo tse ling tsa enjine bakeng sa tokiso le tokiso ka nako.
