AdBlue

AdBlue^® ndi 32,5% yamadzimadzi yothetsera urea yopangidwa kuchokera ku urea yoyera komanso madzi osakanikirana. Dzinalo lingathenso kukhala AUS 32, lomwe ndi chidule cha Urea Aqueous Solution. Ndi madzi opanda utoto wowonekera ndi fungo lokomoka la ammonia. Njira yothetsera vutoli ilibe poizoni, ilibe vuto lililonse mthupi la munthu. Siliwotchera moto ndipo sagawidwa ngati chinthu choopsa chonyamula.

AdBlue^® ndi njira yochepetsera ya NOx yofunikira kuti mugwiritse ntchito othandizira othandizira a Selective Reduction (SCR) mgalimoto za dizilo. Njirayi imayambitsidwa mu chothandizira, pomwe, mutalandira jakisoni mumagetsi otentha, urea yomwe ili mkati imasanduka kaboni dayokisaidi (CO₂ammonia (NH₃).

madzi, ofunda

urea → NKHA₂ + 2NH₃

Amoniya amathandizanso ndi nitrogen oxides (NO_X) zomwe zimachitika poyaka mafuta a dizilo. Chifukwa cha kupangika kwamankhwala, nayitrogeni wopanda vuto ndi nthunzi yamadzi imatuluka mumipweya yotulutsa utsi. Izi zimatchedwa kusankha othandizira othandizira (SCR).

NO + NO₂ + 2NH₃ → 2n₂ + 3H₂O

Popeza kutentha koyambirira kwa crystallization ndi -11 ° C, pansi pa kutentha kumeneku zowonjezera za AdBlue zimalimba. Pambuyo popukuta mobwerezabwereza, ingagwiritsidwe ntchito popanda zoletsa. Kuchuluka kwa AdBlue pa 20 C ndi 1087 - 1093 kg / m3. Kuyeza kwa AdBlue, komwe kumasungidwa mu thanki yosiyana, kumachitika m'galimoto mokhazikika molingana ndi zofunikira za unit control. Pankhani ya mulingo wa Euro 4, kuchuluka kwa AdBlue kowonjezera kumafanana ndi pafupifupi 3-4% yamafuta omwe amadyedwa, pamlingo wa Euro 5 wotulutsa kale ndi 5-7%. Ad Blue^® amachepetsa kugwiritsidwa ntchito kwa dizilo nthawi zina mpaka 7%, potero kumachepetsa pang'ono mitengo yokwera kugula magalimoto omwe amakwaniritsa zofunikira za EURO 4 ndi EURO 5.
