Chii chinonzi mota neutralization system?
Zviri mukati
Mota kusagadzikana system
Izvo zvinodiwa zvezvakatipoteredza zvemotokari dzemazuva ano zviri kuramba zvichiwedzera kuomarara. Vagadziri vemotokari chete vanotevedzera Euro 5. Nekupinda musimba reEuro 6. Neutralization system. Senge inoshandura inoshandura, iyo dizeli particulate sefa uye jekiseni remafuta zvave zvakakosha zvidhinha zvemotokari. Iyo yakasarudzika catalytic inoshandura sisitimu, inonziwo selective catalytic kudzikisira, yakashandiswa kumota dzedhiziri kubvira 2004. Iyo neutralization system inoderedza huwandu hwenitrogen oxides mumagasi emhepo uye nokudaro inobvumira kutevedzana neEuro 5 uye Euro 6 emission standards. Iyo neutralization system yemotokari inoiswa pamatori, motokari uye mabhazi. Parizvino, iyo catalytic converter system inoshandiswa kune Audi, BMW, Mazda, Mercedes-Benz uye Volkswagen mota.
Chii chinonzi neutralization system inosanganisira?
Zita rehurongwa rinoratidza kuti gasi rekushandisa mushure mekurapa rinosarudza. Chete zvirimo zve nitrogen oxides zvinoderera. Nechinangwa chayo, iyo inosarudzika inodzora kudzora system ndiyo imwe nzira kune iyo yekuzadza gasi kudzokorodza system. Nechimiro, yakasarudzika catalytic neutralization system inosanganisira tangi, pombi, kamwene, uye musanganiswa wemakanika. Kudzoreredza catalyst, yemagetsi kutonga system uye kupisa system. Neutralization yenitrogen oxides inoitwa uchishandisa inoderedza mumiriri, inova 32,5% urea mhinduro. Panguva ino yevasungwa, iyo inotonhora pfungwa yemhinduro yakanyanya kukosha. Mhinduro yerea inoshandiswa musystem ine zita rekutengeserana Adblu. Iri idura rakakosha rakaiswa mumarori uye rinochengeta iyo Adblu fluid.
Chii chinogadza huwandu hwetangi
Huwandu uye huwandu hwematangi zvinoonekwa nehurongwa dhizaini uye simba reinjini. Zvichienderana nemamiriro ekushanda, iko kunwiwa kwemvura kuri 2-4% yemafuta ekushandisa. Iyo pombi inoshandiswa kupa fluid kune iyo kamwene pane yakatarisana kumanikidza. Inofambiswa nemagetsi uye inoiswa yakanangana mutangi rechishandiso. Mhando dzakasiyana dzemapombi dzinoshandiswa kutakura mudziyo, senge magiya. Iyo isina-kudzoka solenoid vharafu inosanganisirwa mumutsara wekudzimisa weiyo neutralization system. Paunodzima mota, vharainjini yeinjini inobvumira kuti urea iputirwe kubva pamutsetse kudzokera kutangi. Iyo kamwene inopinza imwe huwandu hwemvura mupombi yekuzadza. Iyo inotevera kamwene, iri mune inotungamira chubhu, iri michina chisanganiso chinokuya iyo inopwa mvura mvura madonhwe. Izvo zvinotenderera magasi ekudzimisa ekuvhengana zvirinani neurea.
Vehicle neutralization hurongwa mudziyo
Iyo pombi chubhu inopera neyekuderedza chinokonzera icho chine huchi hwechivako. Iwo ekugadzirisa madziro akaputirwa nechinhu chinomhanyisa kudzikiswa kwenitrogen oxides senge yemhangura zeolite uye vanadium pentoxide. Iyo yemagetsi yekudzvanya system setsika inosanganisira yekuisa maseru, chinodzora unit uye vanoita. Kudzora masisitimu ekushandisa anosanganisira kumanikidza kwemvura, huwandu hwemvura uye urea sensors. Nitric oxide sensor uye pedza gasi tembiricha sensor. Iyo urea yekumanikidza sensor inoongorora iko kumanikidza kunogadzirwa nepombi. Iyo urea level sensor inoongorora iyo urea nhanho mutangi. Ruzivo nezve iyo nhanho uye kudikanwa kwekutakudza iyo system inoratidzwa padheshibhodhi uye ichiperekedzwa neyekurira chiratidzo. Iyo yekushisa tembiricha inoyera kutonhora kweiyo urea
Injini kutonga
Maseru akanyorwa akaiswa mune module yekupa mvura mutangi. Iyo nitrogen oxide sensor inoona zvemukati zveiyo nitrogen oxides mune yekuzadza magasi mushure mekutendeuka kwekuchinja. Naizvozvo, inofanira kuiswa mushure mekugadzirisa kupora. Iyo yekudzimisa gasi tembiricha sensor inotanga iyo neutralization maitiro zvakananga kana iyo yekuzadza magasi inosvika 200 ° C. Iwo masaini kubva kune ekuisa maseru anotumirwa kune emagetsi control unit, inova iyo injini yekudzivirira unit. Zvinoenderana neiyo algorithm yakasimbiswa, mamwe maactuator anoshandiswa kana uchidzora yuniti yekudzora. Pombi mota, yemagetsi injector, tarisa solenoid vharafu. Zviratidzo zvinotumirwa kune iyo yekudziya control unit.
Nheyo yekushanda kwemotokari neutralization system
Mhinduro yeurea inoshandiswa mune ino sisitimu ine nzvimbo inotonhora pazasi -11 ° C uye kupisa kunodiwa pasi pemamwe mamiriro. Iyo urea yekupisa basa inoitwa neyakasiyana system, iyo inosanganisira ma sensors emvura tembiricha uye yekunze tembiricha. Kudzora unit uye kudziyisa zvinhu. Zvichienderana nemagadzirirwo ehurongwa, zvinodziisa zvinhu zvakaiswa mutangi, pombi nepombi. Mvura inopisa inotanga kana tembiricha iri pasi iri -5 ° C. Iyo yakasarudzika inosimudzira yekudzora system inoshanda seinotevera. Mvura yakabaiwa kubva mumuromo inotorwa neyekuyerera rwizi, rwakavhenganiswa uye rwuchipwa. Munharaunda yekumusoro kweyekuderedza chinokonzera, urea yakaora kuita ammonia uye carbon dioxide. Mune chinokonzeresa, ammonia inopindirana ne nitrogen oxides kuti iite isingakuvadzi nitrogen nemvura.
