Lub cav EA888 yuav tsis tshwm sim los ntawm nws, tab sis nws yuav ua rau cov roj hlawv yog tias nws tawg!

Lub Xya Hli. Peb 31, 2024

Volkswagen/Audi EA888 thib ob tiam roj-gas separator (khoom valve)

Lub tsheb qub tau muab faib ua ob lub zog siab thiab qis zog

Thaum hloov, tsuas yog phim tus lej tsheb qub!

The EA888 engine may not be caused by it, but it will definitely cause oil burning if it is broken!

 

 

● Cov kev cai ib puag ncig xav kom lub crankcase siab yuav tsum yog qhov tsis zoo, uas yog, lub siab nyob rau hauv lub crankcase yuav tsum qis dua qhov qub atmospheric siab los tiv thaiv cov roj crankcase los ntawm kev tawm ncaj qha mus rau hauv cov huab cua thiab ua rau muaj kuab paug;

● Qhov sib txawv ntawm qhov siab thiab qis zog yog qhov tsis zoo siab tus nqi, uas yog txiav txim los ntawm lub siab lub caij nplooj ntoos hlav nyob rau hauv lub tso pa valve;

● Mbar yog ib lub ntsiab lus rau millibars, uas yog chav ntsuas cua siab. Ib square centimeter raug rau 1 kilogram ntawm atmospheric siab, uas yog hu ua "1 bar". Ib txhiab ntawm ib "bar" yog hu ua "millibar". Ib tus qauv atmospheric siab yog sib npaug rau 1013 millibars, yog li 100 millibars yog kwv yees li ib feem kaum ntawm tus qauv atmospheric siab;

 

1. High power version

OE naj npawb:
06H103495AF=AE=AK=K
Tus nqi tsis zoo: -100Mbar (millibar)
Ib txwm tsis zoo siab tus nqi ntawm idle ceev: -115 rau -90 mbar

2. Tsawg zog version

OE naj npawb:
06H103495AB=AC=AD=AH=AJ=B=H=E
Tus nqi tsis zoo: -25Mbar (millibar)
Tus nqi siab tsis zoo ntawm qhov nrawm: -28.5 txog -18.5 mbar

● Yog tias lub tshuab nqus tsev qis dhau lawm, lub crankcase to los yog lub tshuab nqus tsev ntau dhau yuav tsum tau kuaj xyuas;

● Yog tias lub tshuab nqus tsev siab dhau lawm, lub diaphragm thiab lub caij nplooj ntoos hlav nyob rau hauv lub valve yuav tsum tau kuaj xyuas, los yog yuav tsum tau hloov lub valve ncaj qha;

 

★ Cov ntsiab lus txhaum ntawm EA888 thib ob tiam cav tso valve

1. Lub siab tswj valve diaphragm yog perforated

Thawj cov roj hmab dub diaphragm tau yooj yim heev rau hnub nyoog thiab perforate. Tam sim no nws tau raug kho dua tshiab rau lub diaphragm liab nrog lub zog fiber ntau mesh, uas tsis tshua muaj kev puas tsuaj;

The EA888 engine may not be caused by it, but it will definitely cause oil burning if it is broken!

2. Lub qhov dej ntws ntawm cov roj yog thaiv, ua rau cov roj sib cais tsis ntws rov qab li qub

The EA888 engine may not be caused by it, but it will definitely cause oil burning if it is broken!3. Lub sealing gasket yog aging, uas ua rau cov kab ntawm cov roj to nyob ib ncig ntawm nws

The EA888 engine may not be caused by it, but it will definitely cause oil burning if it is broken!

★ Hais txog lub cav roj hlawv

Lub npe hu ua "roj hlawv" yog lub npe hu ua "roj noj tshaj tus qauv".

Lub ntsiab yog vim li cas rau EA888 roj hlawv:

 

1. Valve roj foob kev laus thiab kev puas tsuaj

Valve roj foob muaj ob txoj haujlwm:
Ib qho yog los tiv thaiv kev sib xyaw hauv chav combustion los yog cov pa pa tom qab combustion los ntawm kev xau;
Lwm qhov yog los tiv thaiv cov roj cav los ntawm kev nkag mus rau hauv lub combustion chamber thiab koom rau hauv combustion;
Yog li ntawd, thaum lub valve roj foob muaj lub foob tsis zoo, nws yuav ua rau lub tog raj kheej siab poob thiab qhov teeb meem ntawm "hluav taws xob roj cav".

The EA888 engine may not be caused by it, but it will definitely cause oil burning if it is broken!

2. Txo kev ua haujlwm ntawm lub nplhaib piston

Lub piston feem ntau muaj ob lub nplhaib cua thiab ib lub nplhaib roj.
Lub nplhaib cua yog siv los xyuas kom meej lub foob ntawm lub tog raj kheej thiab lub piston, thaum lub nplhaib roj siv los sib kis thiab khawb cov roj. Thaum lub piston txav mus rau pem hauv ntej, cov roj yog siv rau ntawm lub tog raj kheej phab ntsa, thiab thaum lub piston txav mus rau hauv qab, cov roj yog khawb tawm.
Raws li lub nplhaib piston hnav, nws qhov kev sib khi yuav maj mam txo kom txog thaum cov roj tuaj yeem nkag mus rau hauv lub combustion chamber los ntawm nruab nrab ntawm lub nplhaib piston thiab lub tog raj kheej phab ntsa los koom rau hauv combustion. Qhov no yog lub ntsiab lus tiag tiag ntawm "hlawv roj".

The EA888 engine may not be caused by it, but it will definitely cause oil burning if it is broken!

3. Lub tog raj kheej eccentric hnav lossis hnyav hnyav

Lub nplhaib piston (roj nplhaib) muaj kev sib cuag tsis zoo nrog lub tog raj kheej phab ntsa, thiab cov roj cav tau nce mus rau hauv chav combustion thiab hlawv.

The EA888 engine may not be caused by it, but it will definitely cause oil burning if it is broken!

4. Siv cov roj cav tsis zoo thiab cov roj lim

Cov roj cav tsis zoo tsis tuaj yeem muab kev tiv thaiv zoo rau kev sib txhuam ntawm qhov chaw, yog li nws yuav ua rau kom hnav cov khoom siv cav. Qhov no suav nrog cov piston rings thiab lub tog raj kheej phab ntsa uas peb tau qhia saum toj no. Kev coj txawv txawv yuav ua rau lub cev muaj zog thiab ua rau nws "hlawv roj" ntxov.

The EA888 engine may not be caused by it, but it will definitely cause oil burning if it is broken!

 

5. Cov roj siab tsis zoo

Thaum cov roj siab siab dhau lawm, nws yuav ua rau lub cav foob kom dhau, cov roj yuav xau los yog nkag mus rau hauv lub combustion chamber thiab hlawv, ua rau cov roj tsis zoo.

Cov laj thawj rau cov roj ntau dhau muaj xws li: roj lim lossis roj channel thaiv, ntau dhau ntawm lub siab txwv lub valve qhib, roj viscosity ntau dhau, thiab lwm yam.

The EA888 engine may not be caused by it, but it will definitely cause oil burning if it is broken!

4. Cov roj-gas separator (kua pa valve) tsis sib cais kiag li

Thaum lub crankcase blowby loj dhau los yog lub qhov tso pa tawm nws tus kheej tsis ua haujlwm, cov roj sib tov tsis tuaj yeem sib cais tag nrho, ua rau ib feem ntawm cov roj tsis sib cais coj mus rau hauv chav combustion thiab hlawv.

Yog li ntawd, hloov lub tso pa valve tsis tuaj yeem daws qhov teeb meem ntawm cov roj hlawv.

Thaum lub tsheb hlawv roj, koj tuaj yeem tshawb xyuas lub crankcase nqus tsev vacuum thiab seb lub valve nws tus kheej puas yog. Yog tias nws tshwm sim los ntawm qhov tso pa tawm, koj tuaj yeem hloov lub qhov tso tawm tshiab. Yog tias nws yog vim lwm yam laj thawj, koj yuav tsum hloov lwm yam khoom siv sib xws.

The EA888 engine may not be caused by it, but it will definitely cause oil burning if it is broken!
