Cov tsos mob

Tsis zoo Hnyav Duty EGR Cooler

EGR cua txias or EGR cua txias Nws

cov khoom siv ua kom txias cov pa roj thiab ua haujlwm nrog SCR kom txo tau

emissions ntawm nitrogen oxides (NOx) rau hnyav combustion xyaw.

Lub hom phiaj ntawm EGR txias txias yog los pab txo qis emissions thiab ua tau raws li

tam sim no emission qauv tsim los ntawm US Environmental Protection Agency. Tab sis

Yuav ua li cas yog tias koj lub tshuab EGR pib ua tsis tiav? Qhov ntsuas

EGR txias txias?

Muaj peb yam cim tseem ceeb ntawm EGR cov dej xau:

Cov pa luam yeeb dawb. Thaum EGR

Lub tshuab txias pib ua tsis tiav, nws hloov cov dej txias los ntawm EGR txias

nyob rau hauv koj lub tso pa system. Thaum qhov no tshwm sim, cov pa tawm cuam tshuam nrog

no refrigerant thiab hloov nws mus rau hauv vapor. Qhov no "dawb pa luam yeeb" los ntawm

koj lub tshuab tso pa ntawm koj lub cav hnyav thiab yog qhov tseeb ntawm EGR

tsis kam.

Ploj lawm

Cov dej txias los ntawm koj lub D gas / overflow tank. Thaum koj cov pa roj yog D / ntws

tsis muaj coolant, tab sis koj tsis pom tej yam tshwm sim

sab nraud to (piv txwv li dripping hauv qab lub tsheb) yog qhov hnyav heev

qhia tias koj lub tshuab EGR txias muaj qhov xau sab hauv. Yog li ntawd, qhov no

ntws coolant los ntawm lub tso pa system, uas

tsim tau lub cav overheating los yog nyob rau hauv cov ntaub ntawv no "dawb

haus luam yeeb".

Qhov qias neeg EGR valve, Feem coob

Ib txoj hauv kev zoo los txiav txim siab yog tias koj EGR ua tsis tiav yog saib lub cev

Qhov no. Yog tias koj tshem tawm lub valve, uas nyob rau saum lub cav

ib sab ntawm cov roj lim, nws yuav tsum tau ntim nrog cov pa roj carbon qhuav qhuav (soot)

uas ntawm lub tso pa system. Yog tias koj muaj qhov tsis ua haujlwm EGR txias,

cov roj carbon qhuav yuav raug hloov los ntawm cov slime dub zoo li cov khoom siv. Qhov no

tshwm sim los ntawm kub coolant reacting nrog kub tso pa tawm thiab chav fouling

koj EGR valve.
