Doosan DL08 Cav Rau DX300 Excavator

Basic Specifications

Basic Specifications:

Cav Hom: Inline, plaub-stroke, dej-cooled, turbocharged diesel cav.

Tus naj npawb ntawm cov thooj voos kheej kheej: 4 lossis 6 lub tog raj kheej (DL08 feem ntau yog hais txog 4-lub tog raj kheej series; nws 6-lub tog raj kheej version feem ntau sib haum rau lwm cov qauv, tab sis lawv muab tib lub tshuab).

Txoj Kev Noj Qab Haus Huv: Turbocharged, feem ntau nruab nrog lub tshuab hluav taws xob (cua- rau- cua txias)) txhawm rau txhim kho qhov nqus tau thiab ua haujlwm tau zoo.

Fuel Supply System: Ua haujlwm siab siab -siab ntau rail fuel injection system. Qhov no yog qhov tseem ceeb rau nws cov emissions tsawg thiab kev siv roj tsawg, ua kom muaj kev txhaj tshuaj siab heev thiab ntau yam -stage precision txhaj.

Kev tshem tawm thiab lub zog:

Qhov kev hloov ntawm plaub - lub tog raj kheej cav yog feem ntau nyob ib ncig ntawm 4.0 litres.

Lub hwj chim tso zis npog ntau yam, feem ntau ntawm 80 hp (kwv yees li 59 kW) thiab 200 hp (kwv yees li 147 kW), nyob ntawm cov qauv sib txawv thiab cov qauv siv hluav taws xob, ua tau raws li qhov xav tau ntawm lub zog ntawm ntau yam khoom siv.

Emission Control Technologies:

Yuav kom ua tau raws li cov qauv nruj xws li Tier 4 Kawg / Theem V, DL08 lub cav sib xyaw ua ke ntau yam kev kho mob tom qab:

DOC: Diesel Oxidation Catalyst, siv los oxidize carbon monoxide thiab hydrocarbons.

DPF: Diesel Particulate Filter, siv los ntes thiab rov tsim cov khoom me me kom tshem tawm cov hmoov av.

SCR: Selective Catalytic Reduction System (feem ntau ua ke nrog cov khoom siv hluav taws xob ntau dua lossis cov kev xav tau hauv kev lag luam), siv cov tshuaj urea los hloov cov nitrogen oxides rau hauv nitrogen thiab dej tsis zoo.

EGR: Exhaust Gas Recirculation System (qee cov qauv), txo cov nitrogen oxide tsim los ntawm kev txo qis combustion kub.

Siv High- Cov Roj Zoo: Tsawg- cov roj sulfur diesel ua tau raws li cov qauv teev tseg, cov roj cav tshwj xeeb, thiab cov tshuaj urea pom zoo yuav tsum tau siv. Qhov no yog qhov tseem ceeb rau lub neej ntawm kev kho mob tom qab.

Them mloog mus rau Kev Kho Mob Tom Qab: DPF yuav tsum muaj kev ua haujlwm tsis tu ncua lossis tsis tu ncua. Yog tias cov cuab yeej ua haujlwm ntawm cov khoom qis rau lub sijhawm ntev, ceev faj kom tsis txhob DPF txhaws. Xyuas kom cov urea tank qib txaus rau SCR system.

Kev Kho Kom Zoo: Vim muaj kev tswj xyuas hluav taws xob siab hauv lub cav (ECU), kev kuaj mob thiab kev kho yuav tsum muaj cov cuab yeej tshwj xeeb thiab software. Nws raug pom zoo tias cov no yuav tsum tau ua los ntawm ib tus kws kho mob tau tso cai.

Hauv cov ntsiab lus, Doosan DL08 lub cav yog kev siv thev naus laus zis, zoo - sib npaug, thiab kev ua lag luam- pov thawj nruab nrab - loj diesel fais fab platform. Nws ua tiav kev ua tau zoo, kev siv roj tsawg, tsis muaj emissions, thiab kev ntseeg siab, ua rau nws muaj kev ntseeg siab rau ntau yam khoom zoo - paub cov tuam txhab tsim khoom thoob ntiaj teb. Txawm hais tias tab tom ntsib cov kev cai emission nruj lossis cov chaw ua haujlwm nyuaj, DL08 qhia txog kev sib tw muaj zog thiab yog ib qho ntawm cov khoom lag luam hnub qub ntawm Hyundai Doosan's Infracore thiab Fais fab kev lag luam.
