Takumi Nitrogen Oxide Sensor

Kodi NOx Sensor ndi chiyani?

The NOx sensor ndi gawo la NOx kuchepetsa aftertreatment system yomwe imagwiritsidwa ntchito m'magalimoto a dizilo okhala ndi urea based SCR systems. Sensa yomwe ili kumtunda kwa chothandizira cha SCR imayesa mwachindunji kuchuluka kwa mpweya wa NOx wa injini, yomwe imathandiza kudziwa kuchuluka kwa jakisoni wa urea. Sensa ya NOx kumunsi kwa chothandizira cha SCR imagwiritsidwa ntchito poyang'anira ntchito ya chothandizira. Muyezo wolondola wa NOx ukufunika kwambiri kuti utsatire malamulo okhwima a NOx otulutsa mpweya. Sensor ya NOx imathanso kuyeza ndende ya O2, ngati sensa yamafuta ambiri.

Kodi sensor ya NOx idagwira ntchito bwanji?

Sensa ya NOx imatsimikizira kuchuluka kwa NOx mu mpweya wotulutsa mpweya poyesa kusiyana kwa mpweya wa okosijeni mkati ndi kunja kwa chipinda chofalikira. Pamene ndende ya NOx mu mpweya wotulutsa mpweya ukuwonjezeka, mpweya wa okosijeni m'chipinda choyatsirana udzatsika moyenerera, zomwe zimapangitsa kuti mphamvu yamagetsi isinthe. Chizindikiro chamagetsichi chidzatumizidwa ku galimoto yoyendetsa galimoto (ECU), ndipo ECU idzasintha momwe injini ikuyaka moto potengera ndemanga kuchokera ku sensa kuti muchepetse mpweya wa NOx.

Mitundu ya NOx Sensor

Mitundu iwiri yodziwika bwino ya masensa a nitrogen oxide ndi mutu wathyathyathya wa pini zisanu ndi mitu yayikulu-pini inayi.

Lathyathyathya mutu pini asanu zimagwiritsa ntchito Jiefang, Shaanxi Automobile, Weichai, Xichai ndi zitsanzo zina. Ma pini asanuwa ndi amagetsi, mzere wapansi, CAN high line, CAN low line ndi mzere wosankha maadiresi.

Square head four-pin nitrogen oxide imagwiritsidwa ntchito makamaka pamagalimoto atsopano a Cummins. Zikhomo zinayi zimatanthauzidwa ngati magetsi, mzere wapansi, CAN high line ndi CAN low line.

Zizindikiro za NOX Sensor yoyipa?

>HKugwiritsa Ntchito Mafuta Owonjezera.

Ngati sensor ayi'ECU ikugwira ntchito bwino't kupeza mayankho aliwonse okhudza momwe ma gasi otayira alili, kotero pamenepo'Palibe njira yoti kompyuta idziwe kapena kupanga mafuta oyenera osakaniza kapena chiŵerengero cha mpweya ndi mafuta. Izi zimakakamiza ECU kuganiza moyipa kwambiri ndikuyendetsa mafuta osakaniza kuti atsimikizire kuti ali ndi mphamvu zambiri m'malo ovuta.

> Osakhazikika osagwira ntchito.

Apanso, popeza ECU ilibe njira yodziwira chiyani'Kupitilira ndi injini, iyenera kuganiza moyipa kwambiri. Majekeseni amafuta opangidwa kuti azitha kuyenda mosalekeza ku injini amafa ndi njala komanso/kapena mafunde, zomwe sizingakhale zabwino kwa galimoto yanu pakapita nthawi.

>Kuwala kwa Engine Chenjezo

Mwina yodziwika kwambiri panobe, koma yomwe anthu ambiri amanyalanyaza. Ngakhale sensor yokhayo si't atakwera mkati mwa injini bay, kulephera kulikonse kwa sensa ya NOx kumayambitsa kuwala kwa injini. Iwo'si njira yopanda zipolopolo yopezera zolakwika ndi zovuta za sensor ya NOx, koma imapanga chithunzi chomveka bwino cha zomwe galimoto yanu'kukumana. Kusanthula manambala olakwika pambuyo pa cheke injini kuwala nthawi zambiri kumawulula ngati inu'ndikuchitanso ndi sensor yosweka ya NOx nthawi yomweyo.

Kuti mudziwe zambiri za masensa a Nox, chonde titumizireni pa [imelo ndiotetezedwa].
