GPF fyuluta - ndizosiyana bwanji ndi DPF?

Zosefera za GPF zikuchulukirachulukira m'magalimoto atsopano okhala ndi injini zamafuta. Ichi ndi pafupifupi chipangizo chomwecho monga DPF, ali chimodzimodzi ntchito, koma ntchito zosiyanasiyana. Choncho, sizowona kuti GPF ndi yofanana ndi DPF. 

M'zochita, kuyambira 2018, pafupifupi wopanga aliyense amayenera kukonzekeretsa galimoto ndi injini yamafuta ndi jekeseni wamafuta mwachindunji ndi chipangizochi. Mphamvu yamtunduwu imapanga magalimoto amafuta ndi otsika mtengo kwambiri motero amatulutsa CO2 yaying'ono.  Mbali inayo ya ndalama utsi wochuluka wa zinthu zomwe zimatchedwa mwaye. Uwu ndiye mtengo womwe tiyenera kulipira pachuma cha magalimoto amakono komanso kulimbana ndi mpweya woipa.

Tinthu tating'onoting'ono ndi poizoni kwambiri komanso zowopsa kwa zamoyo, ndichifukwa chake miyezo yotulutsa ya Euro 6 ndi kupitilira apo imachepetsa zomwe zili mu mpweya wotulutsa mpweya. Kwa opanga ma automaker, njira imodzi yotsika mtengo komanso yothandiza kwambiri pamavuto ndikuyika zosefera za GPF. 

GPF imayimira dzina la Chingerezi la sefa ya petulo. Dzina lachijeremani ndi Ottopartikelfilter (OPF). Mayinawa ndi ofanana ndi DPF (Dizilo Particulate Filter kapena German Dieselpartikelfilter). Cholinga chogwiritsanso ntchito ndi chofanana - fyuluta ya tinthu tating'onoting'ono idapangidwa kuti itseke mwaye kuchokera ku mpweya wotulutsa ndikuwusonkhanitsa mkati. Fyuluta ikadzazidwa, mwaye amawotchedwa kuchokera mkati mwa fyuluta kudzera mu njira yoyenera yoyendetsera magetsi. 

Kusiyana kwakukulu pakati pa DPF ndi GPF

Ndipo apa tifika kusiyana kwakukulu, i.e. pakugwira ntchito kwa fyuluta muzochitika zenizeni. Chabwino injini za petulo zimagwira ntchito monga choncho mpweya wotulutsa mpweya uli ndi kutentha kwakukulu. Chifukwa chake, njira yowotcha mwaye yokha imatha kukhala yochepa, chifukwa. kale pakugwira ntchito bwino, mwaye amachotsedwa pang'ono pa fyuluta ya GPF. Izi sizifuna mikhalidwe yokhwima ngati momwe zimakhalira ndi DPF. Ngakhale mumzindawu, GPF ikuwotcha bwino, pokhapokha ngati nyenyezi & dongosolo loyimitsa silikugwira ntchito. 

Kusiyana kwachiwiri kuli m'kati mwa ndondomeko yomwe ili pamwambayi. Mu dizilo, imayamba ndi kupereka mafuta ochulukirapo kuposa momwe injini ingawotchere. Kuchuluka kwake kumapita ku ma cylinders kupita ku makina otulutsa mpweya, komwe kumayaka chifukwa cha kutentha kwakukulu, ndipo motero kumapanga kutentha kwakukulu mu DPF yokha. Izinso zimayaka mwaye. 

Mu injini ya petulo, kuyatsa kwa mwaye kumachitika m'njira yoti kusakaniza kwamafuta ndi mpweya kumakhala kocheperako, komwe kumapangitsa kutentha kwambiri kwa mpweya wotulutsa mpweya kuposa momwe zilili bwino. Izi zimachotsa mwaye musefa. 

Kusiyana kumeneku pakati pa otchedwa DPF ndi GPF fyuluta kusinthika ndondomeko n'kofunika kwambiri kuti pa nkhani ya injini dizilo, ndondomeko nthawi zambiri amalephera. mafuta owonjezera amalowa mu dongosolo lopaka mafuta. Mafuta a dizilo amasakanikirana ndi mafuta, amawatsitsa, amasintha kapangidwe kake osati kumangowonjezera kuchuluka kwake, komanso amawonetsa kuti injiniyo ikugwedezeka. Palibe chifukwa chowonjezera mafuta ochulukirapo ku injini yamafuta, koma ngakhale pamenepo mafuta amatuluka mwachangu kuchokera kumafuta. 

Izi zikuwonetsa kuti ma GPF sakhala ovuta kwa madalaivala kuposa ma DPF. Ndikoyenera kuwonjezera kuti mainjiniya a injini ndi makina awo opangira gasi omwe ali nawo kale zaka zopitilira 20 zosefera za dizilo ndipo izi ndi zomangamanga zovuta. Pakadali pano, kulimba kwawo, ngakhale akugwira ntchito m'malo osavomerezeka (ngakhale kuthamanga kwambiri kwa jakisoni) kuposa kale, ndikokwera kwambiri kuposa koyambirira kwa zaka za m'ma 2000. 

Vuto lingakhale chiyani?

Chowonadi chogwiritsa ntchito fyuluta ya GPF. Kuthamanga kwambiri kwa jakisoni, kusakanikirana kosasunthika komanso kusakhazikika bwino (kusakaniza kumapangika musanayambe kuyaka) kumapangitsa injini yojambulira mwachindunji kutulutsa tinthu tating'onoting'ono, mosiyana ndi injini ya jakisoni yomwe siichita. Kugwira ntchito m'mikhalidwe yotereyi kumatanthauza kuti injiniyo yokha ndi ziwalo zake zimakhudzidwa ndi kuvala kwachangu, kutentha kwakukulu, kudziwotcha kosalamulirika kwamafuta. Mwachidule, injini zamafuta zomwe zimafuna fyuluta ya GPF zimakonda "kudziwononga" chifukwa cholinga chawo chachikulu ndikutulutsa CO2 pang'ono momwe angathere. 

Ndiye bwanji osagwiritsa ntchito jakisoni wosalunjika?

Apa tikubwerera kugwero la vuto - mpweya wa CO2. Ngati palibe amene akuda nkhawa ndi kuchuluka kwa mafuta komanso kugwiritsa ntchito CO2, izi sizingakhale vuto. Tsoka ilo, pali zoletsa zomwe zimayikidwa kwa opanga magalimoto. Kuphatikiza apo, ma injini a jakisoni osalunjika sagwira ntchito bwino komanso amasinthasintha ngati ma jakisoni achindunji. Ndi kugwiritsa ntchito mafuta komweko, sangathe kupereka mawonekedwe ofanana - mphamvu yayikulu, torque pama revs otsika. Kumbali inayi, ogula sakhala ndi chidwi ndi injini zofooka komanso zopanda chuma.

Kunena mosabisa, ngati simukufuna mavuto ndi GPF ndi jakisoni mwachindunji pogula galimoto yatsopano, pitani pagalimoto yamzinda yokhala ndi unit yaying'ono kapena Mitsubishi SUV. Kugulitsa magalimoto amtunduwu kukuwonetsa momwe anthu ochepa amayesera kutero. Ngakhale zikumveka ngati zovuta, makasitomala ndi omwe ali ndi mlandu.
