D-CAT (Advanced Diesel Fuel Treatment Technology)
D-CAT sawv cev rau Diesel Clean Advanced Technology.
Nws yog ib qho txheej txheem uas txo qis cov pa phem hauv cov pa nkev. Hauv plawv ntawm cov thev naus laus zis no yog DPNR lub tshuab lim roj diesel, uas tsis muaj kev saib xyuas dawb thiab, ntxiv rau cov hmoov av, tseem tuaj yeem txo TSIS tso tawm.x. Lub kaw lus tau maj mam tsim thiab tam sim no nyob rau hauv pem hauv ntej ntawm kev kho cov pa pa. Rau qhov zoo dua cov lim dej rov ua dua tshiab, ib qho tshwj xeeb diesel injector tau ntxiv uas tso cov roj diesel ncaj qha rau hauv cov yeeb nkab tso rau ntawm qhov taw tes ua ntej nws nkag mus rau hauv lub turbine. Tsis tas li ntawd, cov txheej txheem rov tsim dua qub tau ua haujlwm zoo li qub, uas yog, yog tias chav tswj hwm txiav txim siab, raws li lub teeb liab los ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, tias DPNR lim yog tag nrho, cov roj diesel raug txhaj, uas tom qab ntawd nce qhov kub hauv lub lim thiab hlawv nws cov ntsiab lus - regeneration. Txhawm rau txo cov nitrogen oxides NOx yog DPNR lim ntxiv nrog cov pa oxidation catalyst.
