Chii chinonzi Automotive turbocharger control
Iyo yekudzora meshini yemotokari turbocharger inonyanya kuzivikanwa nemagetsi inodzorwa epoust gasi turbocharger pressure control system. Iyo sisitimu inoumbwa nepressure relief solenoid valve, pneumatic actuator, bypass valve uye supercharger. Kudzora kwehurongwa booster kudzvanywa kunoitwa kuburikidza nekuvhura uye kuvhara kwevhavhavhavhavha: kana iyo bypass valve yakavharwa, inenge yese gasi rekuburitsa rinoyerera nepakati pe booster, uye iyo booster pressure inowedzera; Kana iyo bypass valve yakavhurwa, chikamu cheiyo gasi rekuburitsa chinoburitswa zvakananga kuburikidza ne bypass chiteshi, uye iyo booster pressure inoderedzwa.
Kuvhura nekuvhara kwevhavhavhavha yekupfuura kunowanikwa neECU (Electronic control Unit) kuburikidza nekutonga kweiyo pressure relief solenoid valve uye pneumatic actuator. Iyo ECU inodzora kumanikidza kwekuwedzera zvinoenderana nekudzvanywa kweiyo manifold, uye iyo bypass valve inovhurwa nekumhanya kukuru uye mutoro wakakura kudzivirira yakawandisa michina uye yekupisa kweinjini pakumhanya kukuru. Pamusoro pezvo, mamwe mamodheru anoshandisawo yakavharwa-loop control system, kuburikidza neiyo chinzvimbo sensor kudyisa iwo chaiwo ekuuraya mhedzisiro kuECU, gadzirisa zvinoenderana nekutsauka, kunyatso kudzora injini torque .
Nheyo yekushanda ye turbocharger ndeyekutyaira turbine kuburikidza nemhepo yekuburitsa gasi inoburitswa neinjini, uye wobva wadzvanya mweya wekupinda kuti uvandudze density yemhepo, nekudaro kuvandudza kugona kwekupisa uye kubuda simba. Turbocharger inoshandisa inertia impulse ye epoust gasi inoburitswa neinjini kusundira turbine mukamuri returbine, inotyaira coaxial impeller kumanikidza mweya mucylinder, inowedzera kudzvanywa uye kuwanda kwemhepo, uye nekudaro inowedzera simba rekubuda reinjini.
Iwo makuru mabasa emotokari turbocharger anosanganisira zvinotevera zvinhu:
Wedzera simba reinjini uye torque : Turbocharger inowedzera huwandu hwemhepo inopinda mucylinder, zvichiita kuti injini ibaye mafuta akawanda panzvimbo imwe chete, nekudaro inowedzera simba reinjini uye torque. Kazhinji, maturbocharger anogona kuwedzera simba guru reinjini ne20% kusvika 40%, uye torque yakakura ne30% kusvika 50%.
Deredza mashandisirwo emafuta uye kuburitsa huturu : Turbocharger inoderedza kushandiswa kwemafuta uye kuburitsa nekugonesa kupisa kweinjini uye nekuvandudza kugona kwekupisa. Kunyanya, iyo turbocharger inogona kuderedza kushandiswa kwemafuta einjini ne5% kusvika 10%, uye kubuda kwemagasi anokuvadza akadai seCO, HC uye NOx zvakare kwakaderedzwa saizvozvo.
Kuvandudzwa kwehupfumi hwemafuta : Injini dzine turbocharger dzinopisa zviri nani, kuchengetedza 3% kusvika 5% yemafuta. Uye zvakare, turbocharger inokwidziridza injini yekufananidza maitiro uye yenguva pfupi yekupindura maitiro ekuvandudza hupfumi hwemafuta.
Gadzirisa kuchinjika kweinjini uye kuvimbika : Turbocharger inogona kuita injini munzvimbo dzakasiyana, tembiricha uye mamiriro emutoro kuchengetedza kuita kuri nani uye kugadzikana, kudzivirira injini isina simba, kugogodza, kupisa uye mamwe matambudziko. Panguva imwecheteyo, ma turbocharger anogona zvakare kuwedzera hupenyu hweinjini uye kuderedza mwero wekutadza.
Plateau compensation function : munzvimbo yebani, nekuda kwemhepo yakatetepa, kushanda kweinjini dzakajairwa kuchakanganiswa uye simba richadzikiswa. Iyo turbocharger inogona kunyatso gadzirisa kurasikirwa kwesimba kunokonzerwa nemhepo yakatetepa nekuwedzera kuwanda kwekudya.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pathiri saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
