Continental sensor inogadzira injini dzedhiziri dzakachena
Vatyairi vanozoziva chaizvo kana mota yavo ichisangana nezvinodiwa zvekubuda.
Exhaust gasi post-kurapwa ndeye yakakosha kukosha kudzikisa zvinokuvadza kubva mumotokari.
Pamwe pamwe nekudzora kabhoni dhayokisaidhi (CO2) kuburitswa, kudzikisira zvinokuvadza nitrogen oxides ndiyo imwe yematambudziko makuru kune indasitiri yemotokari. Ndicho chikonzero muna 2011 iyo yekuGerman inogadzira matairi uye mutekinoroji kune indasitiri yemotokari, Continental, iri kushanda kugadzira Selective Catalytic Reduction (SCR) system.
Mota zhinji dzevatakuri dzedhiziri uye mota dzekutengesa dzakatogadzirwa neiyi SCR system. Mune ino tekinoroji, aqueous solution yeurea inopindirana ne nitrogen oxides muinjini yekupedza magasi, uye nekudaro inokuvadza nitrogen oxides inoshandurwa kuita isina kukuvadza nitrogen nemvura. Kubudirira kweichi chiitiko kunoenderana neyakaringana kuyerwa kweiyo urea nhanho uye kusangana. Imhaka yekukosha kwemetriki aya iyo Continental iri kuvhura sensor yakatsaurirwa kekutanga kubatsira kuwedzera kuvandudza mashandiro eSCR masisitimu uye kuyera kushanda kwawo. Iyo urea sensor inogona kuyera mhando, danho uye kudziya kweiyo urea mhinduro mutangi. Vazhinji vagadziri vemota vari kuronga kushandisa ino nyowani Continental tekinoroji mune yavo mamodheru.
"Urea sensor tekinoroji yedu inopindirana neSCR masisitimu. Iyo sensor inopa data inobatsira kunatsiridza huwandu hweiyo jekiseni urea zvinoenderana neyazvino injini mutoro. Iyi data inodiwa kuti uongorore kupera mushure mekurapa uye injini urea mazinga kuti abatsire mutyairi kuzadza AdBlue panguva yakakodzera, "anotsanangura kudaro Kallus Howe, mutungamiriri we sensors uye powertrains ku Continental. Pasi peiyo nyowani yeEuro 6 e emissions standard, mota dzedhiziri dzinofanirwa kunge dziine urea-yakajairwa SCR catalytic converter, uye kubatanidzwa kweiyo Continental sensor itsva muhurongwa kuchawedzera chivimbo chemutyairi mumabasa ekugadzirisa mushure memotokari.
Iyo yekuvandudza sensor inoshandisa supersonic masaini kuyera kuwanda kweiyo urea mumvura uye huwandu hwemafuta mutangi. Kune izvi, iyo urea sensor inogona kusunganidzwa kungave mutangi kana mupombi yuniti.
Huwandu hwemhinduro yakabaiwa inofanirwa kuverengerwa zvichibva pane ipapo injini mutoro. Kuti uverenge iyo chaiyo jekiseni huwandu, iwe unofanirwa kuziva izvo chaizvo urea zvemukati zveAdBlue mhinduro (kunaka kwayo). Zvakare, mhinduro ye urea haifanire kunge ichinyanya kutonhora. Naizvozvo, kuve nechokwadi chekugara kwakagadzirira sisitimu, zvinodikanwa kudzora tembiricha iri mutangi yeurea, kana zvichidikanwa, kumisikidza iyo yekudziya sisitimu. Chekupedzisira asi chisiri chidiki, panofanirwa kunge paine huwandu hwakaringana hweurea mutangi sezvo iyo supersonic sensor inobvumidza mwero wemvura mutangi kuyerwa kubva kunze. Haisi chete chinhu chakakosha chekudzivirira kwechando, asi zvakare inodzivirira kuora kwezvinhu zvema sensor kana zvemagetsi.
Sero rekuyera mukati meiyo sensor rine zvinhu zviviri zvepiezoceramic zvinoburitsa uye zvinogashira masuperisheni. Iyo nhanho uye mhando yemhinduro inogona kuverengerwa nekuyera iyo yekumira yekufamba nguva yemafungu epamusoro kune iyo nzvimbo yemvura uye yavo yakatwasuka velocity. Iyo sensor inoshandisa kugona kwemasimba emhando yepamusoro kufamba nekukurumidza mune mhinduro ine yepamusoro urea yezvinyorwa.
Kuti uvandudze kuyerwa kunyangwe kana mota iri mune yakamira nzvimbo, yechipiri chikamu cheyero chinopihwa kuti ipe chiratidzo chakavimbika pamatope akakwirira.
