Diesel cav muaj nyob rau hauv ntau lub tsheb loj, xws li tsheb thauj khoom thiab tsheb npav. Nrog ntev-ntau thiab ntau fueled efficiency tshaj roj hlawv cav cov cav no muaj zog. Uas yog ib feem ntawm vim li cas cov cav diesel tau ua haujlwm txav khoom thiab tib neeg. Thaum lub cav diesel yog lub cev muaj zog, cov cav kuj tseem tso pa tawm thiab cov pa uas ua rau peb cov huab cua tsis zoo thiab peb txoj kev noj qab haus huv. Txhawm rau tiv thaiv qhov teeb meem no, peb tuaj yeem siv a diesel roj injector. Kab lus no yuav hais txog yuav ua li cas cov tshuaj no ua haujlwm thiab tso cai rau koj kom txuag tau roj thiab ua pa kom huv.
Thaum lub tshuab hluav taws xob tau tsim kom muaj zog, lawv tuaj yeem hlawv roj ntau, tshwj xeeb tshaj yog nyob rau hauv cov khoom hnyav. Muaj lub tshuab hluav taws xob tso kua hluav taws xob tuaj yeem txhim kho lub cav roj siv tau zoo vim nws tso cai rau cov kua dej tshwj xeeb, hu ua diesel tso kua dej, nkag mus rau hauv cov pa tawm. Cov kua muaj cov dej ntshiab huv thiab ib yam khoom tshwm sim hu ua urea. Lub tshuab hluav taws xob tso hluav taws xob, ib zaug txhaj rau hauv qhov tso pa tawm, tuaj rau hauv kev sib cuag nrog nitric oxides (NOx) uas yog tsim los ntawm lub cav - NOx yog cov pa phem uas feem ntau yuav tsum tau kho. Qhov kev sib cuam tshuam no pab hloov NOx rau hauv tsis muaj nitrogen thiab dej. Qhov no yog qhov tseem ceeb vim nws ua rau lub cav ua haujlwm tau zoo dua, ua haujlwm tib yam thaum siv roj tsawg. Qhov no txhais tau hais tias nws pab koj txuag tau ntau yam ntawm koj cov nqi roj thaum tseem pab txo qis qhov cuam tshuam rau ib puag ncig.
Cov pa luam yeeb thiab cov pa tawm los ntawm lub tshuab hluav taws xob diesel tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv thiab ib puag ncig. Cov pa phem tshaj plaws uas tawm los ntawm lub tshuab diesel yog nitrogen oxide (NOx). Cov pa roj no ua rau huab cua muaj kuab paug thiab ua pa nyuaj rau tib neeg. DFI injectors & NOx REDUCTION txheej txheem nrog DEF & SCR: Siv tau tam sim, diesel cav injector twj tso kua miss yog rov ntxuav cov huab cua, rhuav tshem NOx rau hauv tsis muaj nitrogen thiab dej. Diesel tso kua dej injectors txo cov emissions pom, ua kom peb ib puag ncig muaj kuab paug tsawg thiab peb cov txiaj ntsig tau muaj kev tiv thaiv ntau dua. Txhua tus tau txais txiaj ntsig los ntawm huab cua huv - pab cov neeg nyob ze ntawm txoj kev tsis khoom lossis ua haujlwm hauv cov tshuab hluav taws xob siv hluav taws xob.
Yog li ntawd, koj xav kom tswj koj lub tshuab hluav taws xob tso kua dej kom zoo, kom koj lub cav diesel ua haujlwm zoo. Qhov ntawd txhais tau tias Saib xyuas cov kua dej thiab sab saum toj ntawm cov kua dej thaum nws qis. Los ntawm kev saib xyuas cov kua dej no, koj tuaj yeem ntes cov teeb meem uas tuaj yeem cuam tshuam nrog lub cav ua haujlwm li cas. Thiab koj yuav tsum tsis txhob ntxiv lwm cov kua rau lub diesel tso kua dej injector xws li Yog tias sib xyaw, lawv yuav ua rau muaj kev puas tsuaj loj thiab kho loj. Tsis tas li ntawd, nrog rau kev saib xyuas cov dej, nco ntsoov hu rau lub tshuab hluav taws xob tso kua hluav taws xob ua haujlwm tsis tu ncua rau nws kom nws ua haujlwm tau zoo tshaj plaws. Peb pab neeg ntawm Derun Mechanical nyob ntawm no los xyuas kom meej tias koj lub tshuab hluav taws xob tso kua hluav taws xob tau saib xyuas kom koj lub cav khiav zoo thiab ua haujlwm tau zoo.
Tau ntau xyoo lawm, lub tshuab hluav taws xob diesel tau siv ntau lub tsheb tab sis lawv tau txais txiaj ntsig tom qab qee xyoo vim nws lub zog zoo heev thiab kev siv roj. Tab sis, raws li cov cav tov diesel tau nce, yog li muaj kev nruj ntawm cov pa phem los tiv thaiv cov pa phem uas tsim tawm. Diesel tso kua dej (DEF) yog txhaj rau hauv cov kwj deg ntawm niaj hnub diesel xyaw los pab ua kom tau raws li cov cai nruj heev. Qhov no ua rau muaj kev siv dav dav ntawm cov tshuab hluav taws xob tso kua dej hauv ntau lub tsheb thauj neeg tam sim no, pab ua kom huab cua peb ua pa huv thiab noj qab haus huv rau peb txhua tus.
Nrog diesel tso kua dej injectors, qhov loj me tseem ceeb ntawm kev ua haujlwm. Xaiv qhov zoo tshaj plaws rau koj hom tsheb thiab kev tsav tsheb yog qhov tseem ceeb. Muaj cov twj tso kua mis uas hnyav hnyav tshaj rau cov tsheb loj, thiab cov tshuaj txhaj tshuaj uas siv tau rau cov tsheb me xws li tsheb thiab vans. Nws tseem yog ib qho tseem ceeb uas yuav tau xaiv ib lub injector uas haum rau hom diesel tso kua dej uas koj yuav siv. Kev sib xyaw ntawm cov kua roj diesel tuaj yeem cuam tshuam rau ib puag ncig txawv. Cov neeg ua haujlwm paub txog ntawm Derun Mechanical muaj peev xwm nrhiav tau txoj cai diesel tso kua dej injector rau koj lub tsheb kom ntseeg tau tias kev ua haujlwm zoo ntawm cov khoom siv tsheb thiab txo qis emissions.
