Madzi amtundu wa SCR. Timatsatira miyezo ya chilengedwe
Zamkatimu
SCR imatchedwa kusankha chifukwa idapangidwa kuti ichepetse ma oxide owopsa a nayitrogeni mumipweya yotulutsa mpweya kuchokera ku injini za dizilo. Njirayi ndi yothandiza kwambiri, koma yankho la urea limakhala zowonjezera zowonjezera.
Momwe dongosololi limagwirira ntchito
Urea kudzera mu nozzle imalowa mu mpweya wotulutsa mpweya pambuyo pa utsi wochuluka kupita ku chothandizira. Madziwo amadzutsa kuwonongeka kwa ma nitrogen oxides m'madzi ndi nayitrogeni - zinthu zachilengedwe zomwe zimapezeka m'nyama zakuthengo.
Zofunikira za New Environment Commission ku European Union zikukakamiza opanga magalimoto kuti aziwongolera momwe magalimoto amayendera ndikuyika ma SCR pamagalimoto okhala ndi injini za dizilo.
Zathupi zathupi komanso mankhwala
Madzi a SCR Adblue system, amakhala ndi yankho lamadzi ndi urea:
- Madzi a demineralized - 67,5% yankho;
- Urea - 32,5% yankho.
Adblue ili mu pulasitiki yake kapena thanki yachitsulo, makamaka pafupi ndi thanki yamafuta. Tankiyo ili ndi kapu yabuluu pakhosi la filler, ili ndi zolemba zofanana za Adblue. Makosi odzaza urea ndi akasinja amafuta amakhala ndi ma diameter osiyanasiyana kuti athetse kuthekera kolakwika pakuwonjezera mafuta.
Kuzizira kwa urea ndi -11 ° C, thanki ya urea ili ndi chowotcha chake. Komanso, injini ikayimitsidwa, mpope munjira yosinthira imapopera reagent kubwerera mu thanki. Pambuyo pa kuzizira, urea wosungunuka amakhalabe ndi ntchito yake ndipo ndi yoyenera kugwiritsidwa ntchito.
Kuthamanga kwa madzi ndi zofunikira zogwirira ntchito
Avereji yamadzimadzi ogwira ntchito pa SCR ndi pafupifupi 4% yamafuta a dizilo pamagalimoto okwera, ndipo pafupifupi 6% pagalimoto.
Dongosolo lowunikira pagalimoto lagalimoto limawongolera magawo ambiri a yankho la urea:
- mlingo mu dongosolo.
- Kutentha kwa urea.
- Kuthamanga kwa njira ya urea.
- Mlingo wa jakisoni wamadzimadzi.
Chigawo chowongolera chimachenjeza dalaivala powunikira nyali yosagwira ntchito pa dashboard kuti yankho likugwiritsidwa ntchito mwachangu komanso tanki ilibe kanthu. Dalaivala ali ndi udindo wowonjezera reagent paulendo. Ngati zidziwitso za dongosolo zimanyalanyazidwa, mphamvu ya injini imachepetsedwa kuchokera ku 25% mpaka 40% mpaka reagent itadzazidwa. Chida chamagulu chikuwonetsa chowerengera cha mileage ndipo kuchuluka kwa injini kumayambira; mukakhazikitsanso kauntala, sikungatheke kuyambitsa injini yamagalimoto.
Ndikofunikira kudzaza madzi amtundu wa SCR kuchokera kwa opanga odalirika a urea: BASF, YARA, AMI, Gazpromneft, Alaska. Kudzaza thanki ndi madzi kapena zakumwa zina kulepheretsa mpweya wotulutsa mpweya.
