Chii chinonzi Automotive turbocharger control
Maitiro ekudzora mota ye turbocharger anonyanya kuitwa nemagetsi anodzorwa ne exhaust gas turbocharger pressure control system . Sisitimu iyi ine pressure relief solenoid valve, pneumatic actuator, bypass valve uye supercharger. Kudzora system booster pressure kunoitika kuburikidza nekuvhura nekuvhara bypass valve: kana bypass valve yavharwa, inenge yese exhaust gas inoyerera nepa booster, uye booster pressure inowedzerwa; Kana bypass valve yavhurwa, chikamu che exhaust gas chinoburitswa zvakananga kuburikidza ne bypass channel, uye booster pressure inodzikira .
Kuvhurwa nekuvharwa kwevharuvhu ye-bypass kunoitwa neECU (Electronic control Unit) kuburikidza nekudzora vharuvhu ye-pressure relief solenoid uye pneumatic actuator . ECU inodzora kumanikidzwa kwekuwedzera zvichienderana nekumanikidzwa kwe-incase manifold, uye vharuvhu ye-bypass inovhurwa nekukurumidza uye mutoro mukuru kudzivirira mutoro wakawandisa weinjini nekupisa nekukurumidza. Pamusoro pezvo, mamwe mamodheru anoshandisawo closed-loop control system, kuburikidza ne-position sensor kuti ipe mhinduro chaiyo kuECU, kugadzirisa zvichienderana nekutsauka, kuti itonge torque yeinjini nemazvo.
Nheyo yekushanda kweturbocharger ndeyekufambisa turbine nepamhepo inobuda muinjini, wobva wadzvanya mweya unopinda kuti uvandudze huwandu hwemhepo, nokudaro zvichivandudza kushanda zvakanaka kwekupisa uye simba rekubuda. Turbocharger inoshandisa inertia impulse yemhepo inobuda muinjini kusunda turbine mukamuri returbine, inotyaira coaxial impeller kuti idzvanyirire mhepo mu cylinder, inowedzera kumanikidzwa uye huwandu hwemhepo, uye nokudaro inowedzera simba rekubuda kweinjini.
Mabasa makuru e turbochargers dzemotokari anosanganisira zvinhu zvinotevera:
Wedzera simba reinjini ne torque: Ma turbocharger anowedzera huwandu hwemhepo inopinda mu cylinder, zvichiita kuti injini ikwanise kuisa mafuta akawanda panguva imwe chete, nokudaro zvichiwedzera simba reinjini ne torque. Kazhinji, ma turbocharger anogona kuwedzera simba guru reinjini ne 20% kusvika 40%, uye torque yepamusoro ne 30% kusvika 50%.
Deredza kushandiswa kwemafuta uye kuburitswa kwemhepo: MaTurbocharger anoderedza kushandiswa kwemafuta uye kuburitswa kwemhepo nekuvandudza kushanda zvakanaka kweinjini uye kuvandudza kushanda zvakanaka kwekupisa. Kunyanya, turbocharger inogona kuderedza kushandiswa kwemafuta einjini ne5% kusvika 10%, uye kuburitswa kwemagasi ane njodzi akadai seCO, HC uye NOx kunoderedzwawo saizvozvo.
Kushandiswa kwemafuta kwakagadziridzwa: Injini dzine ma turbocharger dzinopisa zviri nani, dzichichengetedza 3% kusvika 5% yemafuta. Pamusoro pezvo, ma turbocharger anovandudza hunhu hweinjini uye hunhu hwemhinduro dzenguva pfupi kuti mafuta ashandiswe zvakanaka.
Kuvandudza kuchinjika kweinjini uye kuvimbika kwayo: Turbocharger inogona kugadzira injini pakukwirira kwakasiyana, tembiricha nemamiriro ekutakura zvinhu zvakasiyana kuti irambe ichishanda zvakanaka uye yakagadzikana, kudzivirira simba reinjini risinganyanyi kushanda, kugogodza, kupisa zvakanyanya nezvimwe zvinetso. Panguva imwe chete, turbochargers inogonawo kuwedzera hupenyu hweinjini uye kuderedza mwero wekukundikana kwayo.
Basa rekugadzirisa plateau: munzvimbo yeplateau, nekuda kwemhepo isina simba, mashandiro einjini dzakajairika achakanganiswa uye simba richadzikira. Turbocharger inogona kutsiva kurasikirwa kwesimba kunokonzerwa nemhepo isina simba nekuwedzera huwandu hweinopinda.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa painzvimbo! (or) Ndiyo nzvimbo!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
