Vharuvhu yeEGR (vharuvhu yekudzokorodza gasi remhepo) chigadzirwa chemechatronic chakaiswa painjini yedhiziri kudzora huwandu hwemhepo inodzokorodza gasi rinodzoserwa kuhurongwa hwekudyara.
Vharuvhu yeEGR chigadzirwa chemechatronic chakaiswa painjini yedhiziri kuti chidzore huwandu hwemhepo inobuda mumhepo inodzoserwa kuhurongwa hweinopinda. Inowanzo kuwanikwa kurudyi rwemhepo inobuda mumhepo, pedyo nedumbu remuchina we throttle, uye yakabatana nayo nechubhu pfupi yesimbi inoenda kumhepo inobuda mumhepo. Basa rayo nderekudzora huwandu hwemhepo inobuda mumhepo inopinda mumhepo inobuda mumhepo, kuitira kuti huwandu hwakati hwemhepo inobuda mumhepo inopinda mumhepo inobuda ...
Vharuvhu yeEGR yakakamurwa kuita mhando mbiri: mhando yemakanika uye mhando yekudzora yemagetsi.
Vharuvhu yeEGR inoderedza tembiricha yekamuri rinopisa nekutungamira gasi rinobuda mumoto rinobuda muinjini richienda kuinjini kuti rishande mumoto, richivandudza kushanda zvakanaka kweinjini, richivandudza nzvimbo inopisa, uye richideredza mutoro painjini, richideredza zvinobudirira kubuda kweNO compounds, richideredza kugogodza, uye richiwedzera nguva yebasa rechikamu chimwe nechimwe.
Zita rakazara rinonzi Exhaust Gas Recirculation, kureva kuti, exhaust gas recirculation [1] Sisitimu iyi inoshandiswa kuderedza kuburitswa kwenitrogen oxides (NOX) mu exhaust gas. Nitrogen neokisijeni zvinosangana nemakemikari chete kana paine tembiricha yakakwira uye mamiriro ekumanikidzwa kwakanyanya, uye tembiricha nekumanikidzwa mu exhaust chamber ye engine zvinosangana nemamiriro aya, kunyanya panguva yekumanikidzwa kukuru. Kana injini ichishanda pasi pemutoro, vharuvhu yeEGR inovhurika, ichibvumira huwandu hushoma hwe exhaust gas kupinda mu intake manifold uye mu exhaust chamber pamwe chete nemusanganiswa unobvira. Vharuvhu yeEGR inovharwa paidling, uye gasi shoma rinobuda rinodzoserwa ku engine. Gasi rinobuda mumota igesi risingabatike (risina mafuta uye oxidant) risingabatanidzwe mukupiswa mu exhaust chamber. Rinoderedza tembiricha nekumanikidzwa kwekupiswa nekunwisa chikamu chekupisa chinogadzirwa nekupiswa kuderedza kugadzirwa kwe nitrogen oxides. Huwandu hwe exhaust gas hunopinda mu exhaust chamber hunowedzera nekukurumidza kwe engine uye mutoro.
Kudzokorodza gasi rekubuda mumhepo inzira iyo chikamu chegasi rekubuda mumhepo (kana musanganiswa) chinopinzwa mumhepo yakachena (kana musanganiswa) panguva yekushanda kweinjini, uye chinodzoserwa kusirindiri kuti chidzokorodze kuti chibatanidzwe mukupisa. Basa rayo nderekuderedza kuburitswa kweNOx. NOx igesi inokuvadza zvikuru mumuviri wemunhu, iyo inonyanya kugadzirwa mumamiriro ekupisa kwakanyanya uye ane okisijeni yakawanda. Munguva yekushanda kweinjini, kana chikamu chegasi rekubuda mumhepo chikadzoserwa musirindiri nenguva yakakodzera, nekuti chikamu chikuru chegasi rekubuda mumhepo chine simba guru rekupisa, CO2, gasi rekubuda mumhepo rinogona kutora chikamu chekupisa chinogadzirwa nekupiswa uye kuribvisa musirindiri, uye rine mhedzisiro yakanaka pamusanganiswa. Kusanganiswa kwechinhu, nokudaro kuderedza tembiricha yepamusoro uye huwandu hweokisijeni mukupiswa kweinjini, nokudaro kuderedza kuumbwa kwemakemikari eNOx.
Zvisinei, kutenderera kwemhepo zvakanyanya kunokanganisa mashandiro einjini, kunyanya kana injini ichishanda nekumhanya kusingashande, kumhanya kwakaderera uye mutoro wakaderera uye injini ichishanda mukutonhora, uye kana simba reinjini richidikanwa pakuzara kwemhepo (full throttle), kutenderera kwemhepo. Gasi rekubuda mumhepo richakanganisa zvakanyanya mashandiro einjini. Nokudaro, huwandu hwegasi rekubuda mumhepo hunofanira kugadziriswa otomatiki zvichienderana nemamiriro chaiwo ekushanda kweinjini uye shanduko mumamiriro ekushanda. Maitiro ekushanda akaratidza kuti, zvichienderana nemaumbirwo akasiyana einjini, huwandu hwegasi rekubuda mumhepo hunowanzosiyana pakati pe6% ne13%.
Kuti huwandu hwemagasi ekubuda husanyanya kukanganisa mashandiro einjini, mainjini emazuva ano anodzorwa nemagetsi anoshandisawo nzira yekudzora yakavharika yekuchinja kwegasi rekubuda, uye sensor yeEGR valvu inoiswa pavharuvhu yekudzora kwegasi rekubuda (mamwe mamodheru anoshandisawo masensa ekupisa kwegasi rekubuda). kana sensor yekumanikidza), kudzora kwemhinduro yekugadziriswa kwehuwandu hwemagasi ekubuda hunoitwa. Nzvimbo yekufamba mubhizinesi. Kureba kwepasi kubva pasi kwakaderera, uye mwero wekushandiswa kwenzvimbo yemukati ndiwo wakanyanya pakati pezvigadzirwa zvakafanana, izvo zviri 19% zvakakwirira kupfuura zvezvigadzirwa zvakafanana; nzvimbo yakakura.
Yakakodzera mamiriro akasiyana-siyana, huwandu hwechikamu chepakati-chepamusoro che long-axis hunosvika 10.2m³
Muviri webhokisi wakaenzana uye mwero wekushandiswa wakakwira, nzvimbo yakakura ne15% kupfuura zvigadzirwa zvakafanana
Simba guru
Injini yedhiziri yeSAIC π2.0T ine turbo
Mafuta anoshandiswa pamakiromita zana akaderera kusvika 7.8L, simba guru i102kW, uye torque yepamusoro i330N m
Ruzha rwekusashanda runosvika padanho rehofisi re51dB chete
Sisitimu yechitima che2000bar ine kumanikidzwa kwakanyanya, inobatsira pakugadzira mafuta, inoderedza kushandiswa kwemafuta ne20% zvinobudirira
Ndiyo yega mukirasi yayo ine 6-speed automatic transmission, intelligent shifting, uye inoshandisa mafuta zvishoma ne5%
Kudzora kwakangwara
Giya rekushandisa manual re6AMT, iro rinodzorwa nepakati, rinogona kusarudza mafomu akasiyana-siyana ekutumira magiya e6MT, 6AMT, giya racho rakapfava uye rakatsetseka, uye kudzora kuri nyore uye kuri nyore.
Kugadziriswa kwakasimba uye kwemhando yepamusoro kweMIRA chassis kunoita kuti mota inzwe yakafanana neyemotokari inotakura vanhu. Tekinoroji yemhepo inogona kuvandudza kugona kwekudzivirira mugwagwa, uye kuvandudza zvakakwana muganho wekudzora uye kunyaradzwa [19]
Yakavimbika uye inogara kwenguva refu
Pepa resimbi rakarukwa rine mativi maviri, pendi inonyungudika mumvura isingakuvadzi nharaunda yeEPP, maitiro mana ekugadzirisa pendi yephosphating, electrophoresis, middle coating uye topcoat kuitira kuti isasvibiswe kwemakore gumi. (Muyero wenyika unoda makore manomwe)
【Kuchengetedzwa Kwakakwana】: Muviri unotakura mutoro une chimiro chakabatanidzwa chekeji
Maererano neEuropean safety crash design standard, nhengo huru dzemuviri dzakagadzirwa nesimbi yakasimba kwazvo, huwandu hwacho hwakakwira kusvika 50%, uye ingangoita 30% yezvigadzirwa zvakafanana.
Chizvarwa chitsva cheBosch ESP9.1 electronic stability assistance system chinosanganisira ABS, EBD, BAS, RMI, VDC, HBA, TCS nedzimwe nzira, dzinogona kutarisa mamiriro ayo chero nguva panguva yekutyaira kudzivirira kutsvedza kwemotokari kana kuzununguka panguva yekubhureka nekukona kwemuswe kuti ive nechokwadi chekuti yakachengeteka pakona.
