Diesel Injector Roj Injector 095000-6383 Denso Injector rau Komatsu Excavator

Nrog rau txoj kev loj hlob sai ntawm lub tsheb diesel cav, diesel cav emission teeb meem tau nyiam heev, thiab lub teb chaws tau tshaj tawm ntau thiab ntau nruj emission cov cai thiab cov cai. Txawm hais tias tam sim no muaj ntau lub tshuab hluav taws xob pib siv lub tshuab hluav taws xob siab kom txo tau cov roj noj thiab txo cov emissions, tab sis nyob rau hauv peb cov xwm txheej tam sim no, cov tshuab roj txhaj tshuaj twj tso kua mis tseem nyiam los ntawm ntau tus neeg siv vim nws pheej yig tus nqi, kev ntseeg tau zoo, yooj yim. tu thiab lwm yam zoo.... Tam sim no, lub ntsiab emission tswj nyuaj ntawm lub cav diesel nyob hauv NO; Thiab particles (PM), ob lub pa phem yog qhov sib txawv rau ib leeg ntawm cov xwm txheej tsim, thiab nws tsis tuaj yeem siv ib qho kev txhais tau tias kom ua tiav kev tswj hwm ib txhij ntawm ob cov pa phem no. TSIS TAU, yog lub ntsiab lus dav dav rau ntau yam oxides ntawm nitrogen thaum lub sij hawm combustion, xws li TSIS MUAJ, TSIS MUAJ:, N: 0. Etc. Tus naj npawb ntawm NO yog qhov loj tshaj plaws, thiab qhov ntau lawm ntawm NO hauv cov txheej txheem combustion feem ntau nyob ntawm qhov kub thiab txias. . Tsis tas li ntawd, cov pa oxygen concentration, tshwj xeeb tshaj yog cov atomic oxygen concentration nyob rau hauv lub combustion cheeb tsam, muaj ib tug tseem ceeb rau NO. Tus nqi ntau lawm kuj tseem ceeb heev. Tsis tas li ntawd, cov tshuaj tiv thaiv kuj yuav siv sij hawm, nitrogen thiab oxygen nyob rau hauv siab kub tuav lub sij hawm yog NO. Tus nqi ntau lawm yog lwm qhov tseem ceeb. Kub kub, oxygen enrichment thiab oxygen thiab nitrogen retention lub sij hawm ntawm qhov kub thiab txias txiav txim NO nyob rau hauv lub diesel cav combustion txheej txheem. Peb lub ntsiab ntawm cov qoob loo loj. PM yog tsim los ntawm qhuav soot, soluble organic Cheebtsam, uas yuav txo tau los ntawm kev txo cov sulfur ntsiab lus ntawm diesel, thiab sulfates. Soluble organic Cheebtsam yog hnyav hydrocarbons, uas yuav raug tshem tawm los ntawm oxidation catalysts, yog li txo particle emissions yog tsom rau txo qhov tsim ntawm qhuav soot 1. Yuav kom txo tau cov emission nqi ntawm NO, static feed ua ntej lub kaum sab xis yuav tsum tau ncua, tab sis nws yuav ua kom cov pa luam yeeb thiab PM. Qhov no yuav tsum tau xaiv txoj cai injector, lub injector aperture, kev kub siab khiav optimization, shorten lub combustion ncua sij hawm, nrhiav txoj cai zoo li qub roj mov ua ntej lub kaum sab xis, ua kom tiav NO. Thiab PM tus nqi poob rau tib lub sijhawm, kom lub tshuab hluav taws xob diesel emission tau raws li lub teb chawsⅢtus qauv emission.
