Ukuvuza kukawoyela kwe-turbocharger imodi yokwehluleka engaholela ekwehleni kokusebenza, ukusetshenziswa kukawoyela, nokungahambisani nokukhishwa kwemikhiqizo.Ukuqanjwa kabusha kwakamuva kokuvalwa kukawoyela kuka-Cummins kunciphisa lezi zingozi ngokuthuthukiswa kohlelo lokuvala oluqine kakhudlwana oluncoma ezinye izinto ezintsha ezihamba phambili ezenzelwe ama-turbocharger e-Holset®.

Ubuchwepheshe bokucacisa kabusha uwoyela obuvela ku-Cummins Turbo Technologies (CTT) bubungaza izinyanga eziyisishiyagalolunye butholakala ukuze bamakethe.Ubuchwepheshe boguquko, okwamanje obusetshenziswa kwilungelo lobunikazi lamazwe ngamazwe, bufanele izicelo kuzo zonke izimakethe ezisemgwaqeni omkhulu nangaphandle komgwaqo omkhulu.

Yethulwa ngoSepthemba 2019 engqungqutheleni yama-24 ye-Supercharging eDresden ephepheni elimhlophe elithi, “Ukuthuthukiswa Kophawu Oluthuthukisiwe Lwe-Turbocharger Dynamic Seal,” lobu buchwepheshe bathuthukiswa ngokucwaninga nokuthuthukiswa kwe-Cummins (R&D) futhi baphayona nguMatthew Purdey, umholi weqembu ku-Subsystems Engineering e-. I-CTT.

Ucwaningo luqhamuke ekuphenduleni kumakhasimende afuna izinjini ezincane ezinamandla amakhulu, kanye nekhabhoni ephansi.Ngenxa yalokhu, uCummins ubelokhu ezinikele ngokuqhubekayo ekuletheni okuhle kumakhasimende ngokuqhubeka ehlola izindlela ezintsha zokuthuthukisa ukusebenza kwe-turbocharger nangokucabangela intuthuko ethinta ukuqina, kanye nokusebenza kanye nezinzuzo zokukhishwa kwegesi.Lobu buchwepheshe obusha buthuthukisa futhi amandla okuvala uwoyela ukuze kunikeze izinzuzo eziningi kumakhasimende.

 Yiziphi izinzuzo zobuchwepheshe obusha bokuvala uwoyela?

Ubuchwepheshe obusha bokufaka uphawu be-Holset® turbocharger buvumela i-turbo phansi isivinini, ukwehlisa, ukuvimbela ukuvuza kwamafutha ezinhlelweni zezigaba ezimbili futhi inika amandla ukuncishiswa kwe-CO2 ne-NOx kobunye ubuchwepheshe.Ubuchwepheshe buphinde buye bathuthukisa ukuphathwa kwe-thermal nokuthembeka kwe-turbocharger.Ngaphezu kwalokho, ngenxa yokuqina kwayo, kuthinte kahle imvamisa yokugcinwa kwenjini ye-diesel.

Ezinye izici ezibalulekile nazo zacatshangelwa lapho ubuchwepheshe bokuvalwa busezigabeni zocwaningo nentuthuko.Lokhu kufaka phakathi ukuvumela ukwenziwa kahle kwe-compressor stage diffuser kanye nedrayivu yokuhlanganisa eduze phakathi kokwelashwa kwangemuva ne-turbocharger, ukuhlanganiswa osekuvele kungaphansi kwe-R&D ebalulekile evela ku-Cummins futhi kwakha ingxenye ebalulekile yomqondo Wesistimu Edidiyelwe.

Yiluphi ulwazi u-Cummins analo ngalolu hlobo locwaningo?

I-Cummins ineminyaka engaphezu kwengu-60 yokuhlangenwe nakho kokuthuthukisa ama-turbocharger e-Holset futhi isebenzisa izindawo zokuhlola zasendlini ukwenza ukuhlola okuqinile nokuhlaziya okuphindaphindiwe emikhiqizweni emisha nobuchwepheshe.

“I-Multi-Phase Computational Fluid Dynamics (CFD) yasetshenziswa ukumodela ukuziphatha kukawoyela ohlelweni lwezimpawu.Lokhu kuholele ekuqondeni okujule kakhulu kokusebenzelana kukawoyela/igesi kanye nefiziksi edlalwayo.Lokhu kuqonda okujulile kube nomthelela ekuthuthukisweni kwedizayini ukuze kulethwe ubuchwepheshe obusha bokuvala ngokusebenza okungenakuqhathaniswa, "kusho u-Matt Franklin, uMqondisi - Ukuphathwa Komkhiqizo & Nokumaketha.Ngenxa yalolu hlobo lokuhlola oluqinile, umkhiqizo wokugcina udlule ikhono lokuvala ngokuphindwe kahlanu kunamaphrojekthi ahlosiwe.

Iluphi olunye ucwaningo okufanele amakhasimende alindele ukulibona ku-Cummins Turbo Technologies?

Ukutshalwa kwezimali okuqhubekayo ocwaningweni nasekuthuthukisweni kobuchwepheshe be-diesel turbo kuyaqhubeka futhi kukhombisa ukuzibophezela kukaCummins ekuletheni izixazululo ezihamba phambili embonini zikadizili kuyo yonke imakethe esemgwaqweni onguthelawayeka nangaphandle komgwaqo omkhulu.

Ukuze uthole ulwazi olwengeziwe mayelana nokuthuthukiswa kobuchwepheshe be-Holset, joyina i-Cummins Turbo Technologies newsletter njalo ngekota.
