Ina cikin tsararraki da suka sami damar shaida, a cikin shekaru goma da suka gabata, jinkirin mutuwar injinan bugun jini 2 akan babura. Na tuna cewa matsalar da aka nuna ga injunan da suka yi amfani da wannan zagaye na konewa yana da alaka da konewar mai a cikin iska / man fetur, wanda ya haifar da "manyan" allurai na gurbataccen iska. Saboda haka, irin wannan matsalar da aka nuna a halin yanzu ga injin Diesel.
Kamar yadda lamarin yake a yanzu a injinan dizal, a wancan lokacin masana'antun da dama a duniya sun yanke shawarar kawo karshen injunan bugun bugun jini. Duk da haɓaka rashin sha'awar samfuran samfuran a cikin injunan bugun jini 2, gaskiyar ita ce masu amfani sun ci gaba da daraja waɗannan injunan.

Kada ku taɓa yin fare akan injiniyoyi - shawara ce (...)
Duk da haka injinan bugun bugun jini 2 sun kusan bace. A gasar babu alamar su… amma sun dawo! Godiya ga bincike da haɓaka fasahar allura, KTM, ɗaya daga cikin manyan samfuran babur na Turai, ya sami nasarar farfado da injunan bugun jini 2 a cikin babura na Enduro. Idan kuna sha'awar batun, zaku iya ziyartar wannan rukunin yanar gizon, a nan an yi bayanin duka, domin wannan gabatarwa ce kawai don magana game da injin Diesel ...
Komawa kan jigon injunan diesel, kwanan nan an gabatar da fasahohi guda biyu waɗanda za su iya canza yanayin al'amura da kuma jinkirta mutuwar waɗannan injunan, kamar yadda ya faru da injunan bugun jini 2. Mu hadu dasu?
1. ACCT (Amonia Creation and Conversion Technology)
Daga Jami'ar Loughborough ta zo ACCT (Amonia Creation and Conversion Technology). A aikace, wannan tsarin ne wanda ke aiki a matsayin "tarkon" wanda ke lalata sanannun ƙwayoyin NOx, wanda, fiye da ƙazanta, suna da illa ga lafiyar ɗan adam.
Kamar yadda kuka sani, injinan dizal na baya-bayan nan waɗanda ke biyan kuɗin Euro 6 suna sanye da tsarin rage yawan kuzari (SCR) waɗanda ke amfani da ruwan AdBlue don canza NOx zuwa iskar gas mara lahani. Babban bidi'a na ACCT shine maye gurbin AdBlue, tare da wani fili mai inganci.
Farfesa Graham Hargrave, Jami'ar LoughboroughMuna sane da matsalar dizal a farkon sanyi. Wannan shi ne inda Diesels ya fi ƙazanta. (...) Tsarin mu yana guje wa wannan gurbataccen yanayi a cikin yanayi na ainihi.
To menene matsalar AdBlue? Babban matsala tare da AdBlue shine cewa yana aiki ne kawai a yanayin zafi mai yawa - wato, lokacin da injin yana "zafi". Akasin haka, ACCT na iya canza iskar gas mai guba zuwa iskar da ba ta da lahani a cikin tazarar zafi mai faɗi. Yayin da yake da tasiri har zuwa -60º Celsius, wannan sabon sinadari yana aiki kowane lokaci. Wani abu da zai taimaka (mai yawa!) Injin Diesel lokacin da aka karɓi sabon ma'auni na WLTP - wanda zaku iya ganowa anan - kuma wanda zai gwada injunan a ƙarƙashin ainihin yanayin amfani.
2. CPC Speedstart
Tsarin na biyu ya fito ne daga Ostiriya kuma an ƙirƙira shi ta Controlled Power Technologies (CPT). Ana kiransa Speedstar kuma yana ci gaba aƙalla shekaru 15.
Kamar yadda kuke gani daga hotuna, Speedstar yayi kama da mai canzawa – ga wanda bai san me ake kira alternator ba, wani bangare ne da ke canza makamashin motsin injin zuwa wutar lantarki ta bel. Matsalolin masu canzawa shine suna haifar da inertia a cikin aikin injunan konewa don haka suna kara rage karfin makamashi - wanda bisa ga dabi'a ya riga ya ragu sosai. Shawarar CPT ita ce Speedstar ta maye gurbin na'urori na al'ada.
Ka'idar aiki ta Speedstar abu ne mai sauƙi. Lokacin da injin ba ya cikin nauyi, yana aiki azaman janareta na wuta (kamar masu canza sheka), yana cin gajiyar motsin injin don samar da wutar lantarki har zuwa 13kW. Lokacin da aka yi lodi, Speedstar ya daina aiki a matsayin janareta na makamashi kuma ya fara aiki a matsayin injiniyan taimako ga injin konewa, yana ba da wutar lantarki har zuwa 7kW.
Godiya ga wannan taimakon (duka a cikin ajiya da isar da makamashi) Speedstar yana sarrafa rage fitar da NOx har zuwa 9% da amfani har zuwa 4.5% - wannan a cikin injin diesel na 3.0 V6. Speedstar na iya aiki tare da tsarin lantarki na 12, 14 da 48V.
Don kwantar da hankali, wannan tsarin yana amfani da da'ira mai sanyaya kamar injin. Wani fa'idar wannan tsarin shi ne, ana iya daidaita shi da injinan mai. Don haka albishir ne kawai.
Da gaske ne Diesels za su ƙare?
Kada ku taɓa yin fare akan injiniyoyi - shawara ce. Waɗannan mutanen suna da ikon sa mu hadiye, ta hanyar abubuwan da suka ƙirƙira, gaskiya da yawa waɗanda muke tunanin ba za su iya fahimta ba. Wataƙila muna fuskantar ɗayan waɗannan shari'o'in tare da sanarwar, tabbatacciyar mutuwar injunan Diesel. Ko kuma ba a tabbata ba... lokaci ne kawai zai nuna.
Ee, taken wannan labarin ya kasance nuni ne ga shahararriyar muhawarar tsakanin Álvaro Cunhal da Mário Soares - mutane biyu a tarihinmu waɗanda ba sa buƙatar gabatarwa.
