Icho chikonzero ndechekuti maitiro aya haaitike pamasimba emagetsi einjini yemukati yemoto, kana kumhanya kwayo kuchikwira. Izvo zvinongoshanda zvakaderera nepakati nepakati rpm (mune mayuniti epeturu) kana idle uye yakaderera rpm (mune kesi yedhiziri injini).

Nekudaro, chinangwa cheESGR system kudzora huturu hwekuzadza. Nekuda kweizvi, mota ine mikana yakawanda yekukwana muchimiro chemamiriro ezvakatipoteredza. Inoshandiswa pane chero yazvino injini yemukati yemoto, zvisinei nekuti ipeturu kana dhiziri. Chete caatat ndeyekuti iyo system haina kuenderana nemamwe mayuniti akave akavezwa ne turbocharger.

General mashandiro emitemo yeiyo chiutsi gasi kudzokorodza system

Kunyangwe nhasi paine marudzi akati wandei ehurongwa umo kubatana kweiyo yakawanda chiutsi kune iyo inopinda kuburikidza neyepneumatic vharafu kunoitika, ivo vane yakajairika musimboti wekushanda.

Iyo vharafu haigare yakavhurika. Kana injini inotonhora ikatanga, ichimhanya isina basa, uyezve painosvika pakakwirira crankshaft kumhanya, throttle inofanira kuramba yakavharwa. Mune mamwe maitiro, iyo sisitimu ichashanda, uye kamuri yekupisa yega yega silinda-pisitoni boka rinogashira hushoma hwemafuta emagetsi zvigadzirwa.

Kana chishandiso chikaita nekumhanyisa kweinjini kana mukuita kwekusvika tembiricha yayo yekushandisa (nezve izvo zvazvinofanira kuva, verenga pano), iyo unit ichave isina kugadzikana. Kubudirira kukuru kwevhavha yeEGR kunowanikwa chete kana injini ichimhanya padhuze nepakati nepakati rpm. Mune mamwe maitiro, kusungwa kwe nitrogen oxides yakanyanya kuderera.

Kana injini ichidziya, kupisa tembiricha mumakamuri hakusi kwakanyanya zvekuti huwandu hwakawanda hwe nitrous oxides hunoumbwa, uye hushoma hwekupera haudiwe kudzoka kumasirinda. Izvi zvinoitikawo pakumhanya kwakaderera. Kana injini ikasvika pakumhanya kwazvo, inofanira kukudziridza simba rakakura. Kana iyo vharuvhu ikakwidziridzwa, inongopindira, nekudaro, mune ino modhi, sisitimu ichave iri mune isingashande nyika.

Zvisinei nemhando yemasisitimu, chinhu chakakosha mavari iguruva rinovharira mukana wekubuda kwemagasi ekushandisa mukutora. Sezvo tembiricha yakakwira yerwizi rwizi inotora huwandu hwakawanda kupfuura iyo yakatonhorera analogue, gasi rekudzimisa rinoda kutonhodzwa kuitira kuti mwenje weHTS usaderere. Kune izvi, kune imwezve inotonhorera kana intercooler inosangana neinjini kutonhora system. Iyo dunhu mune yega yega mota modhi inogona kunge yakasiyana, asi ichave iine radiator iyo inogadzikisa maitiro ekuchengetedza yakakwana tembiricha yekushandisa.

Kana ari injini dzedhiziri, vharuvhu iri yakavhurika paXX. Iyo vharuvhu iri mune yekudyira system inokwevera iyo yekuzadza gasi mukati memasirinda. Mune ino modhi, injini inogamuchira ingangoita makumi mashanu muzana yemweya wekudzimisa (zvine chekuita nemhepo yakachena). Sezvo kumhanya kuri kuwedzera, iyo damper actuator inofamba zvishoma nezvishoma ichienda kunzvimbo yakavharwa. Izvi ndizvo chaizvo zvinoshanda dhiziri.
