Auto Parts Roj Injector Diesel Txhaj 23600-69105 rau Nws Pib Roj Common Rail Nozzle Injector

Tsawg ceev ob-stroke Marine diesel xyaw, tus yam ntxwv ntawm kev lag luam zoo thiab kev ntseeg siab, tau siv dav hauv cov nkoj loj, tsav tsheb li 70% ntawm cov khoom thauj thoob ntiaj teb, thiab ua lub luag haujlwm tseem ceeb hauv ntiaj teb kev lag luam.Tsawg ceev ob stroke Marine diesel cav muaj lub zog siab thiab siab emission ntawm cov khoom tsis zoo.Lub Koom Haum Thoob Ntiaj Teb Maritime (IMO) tau pib siv Tier III cov qauv hauv qee thaj chaw tswj kev tso pa tawm hauv xyoo 2016, xav kom Marine diesel xyaw nrog qhov nrawm qis dua 130r / min kom tawm tsis tshaj 3.4g / (kW·h) ntawm NOx hauv emission tswj cheeb tsam.Cov nkoj uas ua tsis tau raws li cov qauv emissions ntsib tsis tuaj yeem caij nkoj tawm ntawm ntug dej hauv qee lub tebchaws tsim.Tam sim no, muaj ob txoj hauv kev tseem ceeb rau kev ceev Marine diesel cav kom ua tau raws li Tier III emission qauv: (1) kev xaiv catalytic txo (selectivecatalyticreduction, SCR) thev naus laus zis, catalytic txo ntawm NOx los ntawm kev ntxiv urea N2, xav tau ib qho ntxiv cov khoom loj tom qab ua tiav, thiab cov nqi kho mob siab;(2) Lub tshuab hluav taws xob tso pa tawm (EGR) txo qhov kub thiab txias hauv lub tog raj kheej los ntawm kev qhia tawm cov pa tawm, yog li inhibiting tiam NOx hauv lub tog raj kheej, tab sis ua rau muaj roj ntau ntxiv.Nyob rau hauv xyoo tas los no, nrog rau thawj daim ntawv thov ntawm kev kub siab ib puag ncig rail technology nyob rau hauv qis ceev Marine xyaw, kev txhim kho ntawm kev txhaj tshuaj system layout thiab txhaj cov tswv yim yooj tau ua pov thawj tias muaj peev xwm zoo los txhim kho cov roj hauv lub tog raj kheej thiab cov roj sib xyaw thiab cov txheej txheem sib xyaw.Nyob rau hauv cov ntaub ntawv, lub micro-genetic algorithm yog siv los optimize lub pre-injection tsis, thiab nws pom tau hais tias qhov tsim nyog pre-injection tswv yim yuav txo tau lub ignition ncua sij hawm, txhim kho cov combustion efficiency thiab zoo txo ​​cov roj noj.
