Chii chinonzi mota chopper?
Chishandiso chemotokari chinoshandura simba, chinowanzoreva chishandiso chechikamu muhurongwa hwenguva yemagetsi (VVT), chinhu chakakosha muhurongwa hwechitima chevharuvhu yeinjini. Chinoshandiswa kugadzirisa nguva yekuvhurwa nekuvhara kwemavharuvhu ekupinda kana ekubuda simba kuti injini ishande zvakanaka, ichengetedze mafuta, uye huwandu hwemhepo inobuda pasi pemamiriro akasiyana-siyana ekushanda.
Basa rayo guru nderekushandura kona yechikamu pakati pe camshaft ne crankshaft zvichienderana nemamiriro ezvinhu chaiwo akadai sekumhanya kweinjini, mutoro, uye tembiricha, nokudaro zvichiita kuti nguva yevharuvhu irambe ichichinja. Injini dzine nguva yakatarwa yevharuvhu hadzigone kuyera torque yekukurumidza uye simba rekukurumidza, nepo phase shifter, kuburikidza nekugadzirisa kwakangwara, inobvumira injini kuwana kugona kwakanakisa kwekupinda nekubuda kwemhepo mumamiriro akasiyana-siyana.
Tsananguro pfupi yekushanda kwenheyo
Chishandiso che phase chinowanzoiswa kumberi kwe camshaft uye chakabatana ne timing chain kana pulley. Chimiro chayo chikuru chine rotor yakabatana zvakasimba ne camshaft uye stator yakabatana ne timing pulley. Makomba emafuta akavharirwa anoumbwa pakati pe rotor ne stator.
Hydraulic phase shifter (inotonga): Oiri yeinjini, iri pasi pekumanikidzwa kwepombi yemafuta, inoendeswa zvakananga kukamuri repamberi kana retard rechikamu che phase shifter kuburikidza nevharuvhu yekudzora mafuta (OCV valve). Nekudzora kumanikidzwa kwemafuta, rotor inotenderera zvichienzaniswa ne stator, nokudaro ichichinja chikamu che camshaft. Semuenzaniso, kupa mafuta kukamuri repamberi kunogona kuita kuti vharuvhu ivhurike nekukurumidza kuti iwedzere torque yakaderera; kupa mafuta kukamuri reretard kunogona kunonotsa kuvhurwa kwevharuvhu kuti iwedzere simba rekukurumidza.
Chinochinja-chinja chemagetsi (tekinoroji inobuda): Semuenzaniso, chinochinja-chinja chemagetsi chakagadzirwa neLuK chinoshandisa chimiro chemakanika chinofambiswa nemota chine mativi matatu, chinobatanidza zvakananga camshaft, pulley, uye mota. Nekudzora kumhanya kwemota nemazvo, kutenderera pakati pe camshaft nepulley kunowanikwa, nokudaro kuchigadzirisa nguva yevharuvhu. Chimiro ichi hachina chekuita nekumanikidzwa kwemafuta einjini, chine kumhanya kwekupindura nekukurumidza, chakarurama pakudzora, uye hachikanganisike nekusimba kwemafuta einjini pakupisa kwakaderera.
Zvakanakira zvikuru
• Wedzera simba rinobuda: Gadzirisa kona inopindirana nevharuvhu pakumhanya kwakanyanya kweinjini, wedzera huwandu hweinopinda, uye wedzera simba reinjini.
• Kuvandudza kushandiswa kwemafuta: Kuzadzisa Miller cycle effect nekunonotsa kuvharwa kwevharuvhu yekudyara kana paine mitoro yakaderera, zvichideredza kurasikirwa kwekupomba.
• Kuderedza utsi: Kupisa zvakakwana kunoderedza kugadzirwa kwemagasi anokuvadza (akadai seCO, NOx, uye HC).
• Kuvandudza kuchinjika: Kunyanya chinoshandiswa nemagetsi, chinogona kuchinjika zvakanyanya kuchinjika nekupisa kweinjini uye mamiriro ekushanda.
Kusanzwisisana kwakajairika kutsanangurwa
• Phase shifter ≠ phase sensor: Phase shifter ndiyo actuator, ine basa re "kugadzirisa"; nepo phase sensor (yakadai se camshaft position sensor) iriyo sensing mechanism, ine basa re "kutarisa" nzvimbo chaiyo ye camshaft uye kudzorera chiratidzo kuinjini control unit (ECU) kuti igadzire closed-loop control.
• Phase shifter ≠ camshaft variable phase controller: Izwi rekupedzisira iri ndiro rinoshandiswa nemakambani akaita seAudi pachirongwa chavo chekudzora system yeVVT, uye chikamu chayo chikuru che actuator iphase shifter.
Muchidimbu, mota inochinja-chinja chikamu chimwe chete pamichina yemazuva ano kuti ishande zvakanaka, yakachena, uye ine simba rakawanda. Kugadzirwa kwayo kuri kuchinja kubva pamhando yemagetsi yechinyakare kuenda kumhando yemagetsi chaiyo uye yakavimbika.
Muchikamu chemotokari, izwi rekuti "phase shifter" rinowanzo reva zvikamu zviviri zvakasiyana zvebasa, uye mabasa azvo chaiwo anoenderana nehurongwa hwazvinoshandiswa.
• VVT phase shifter (variable valve timing system): Ichi chinhu chakakosha musystem yekutonga injini. Basa rayo guru nderekugadzirisa dynamically dynamically rotating phase ye camshaft zvichienderana nemamiriro ekushanda einjini panguva chaiyo (senge kumhanya uye mutoro). Nekuchinja nguva yekuvhura nekuvhara kwemavalvu ekupinda uye/kana ekubudisa, inogona kugadzirisa intake efficiency uye combustion process mu cylinder, zvichiita kuti simba reinjini riwedzere, kuvandudza mafuta, uye kuderedza emissions. Automobile power system regulator (voltage regulator): Chikamu ichi chine basa rekutarisa nekudzora output voltage yejenareta yemotokari. Nekuda kwekuchinja kwekumhanya kweinjini, speed yejenareta inochinja-chinja, izvo zvinokonzeresa kusagadzikana output voltage. Voltage regulator inodzora magnetic current mukati mejenareta kuti ive nechokwadi chekuti output voltage inoramba yakagadzikana pamutengo wakarongwa (kazhinji inenge 14.0V). Izvi zvinodzivirira zvinobudirira michina yemagetsi iri mubhazi kubva pakuchinja-chinja kwevoltage uye ine mabasa ekudzivirira overcharge current uye kudzima reverse current (backflow) kudzivirira bhatiri nejenareta.
