Downpipe - yog dab tsi?

Downpipe yog qhov tseem ceeb ntawm txoj kev tso pa tsheb ntawm ib lub tsheb, dhau ntawm kev tso pa thiab cov catalytic converter (catalyst)). Coob tus neeg nyiam lub tsheb them sai sai rau qhov cov yeeb nkab no vim tias nws tsis cuam tshuam rau kev ua haujlwm ntawm lub cav tsheb atmospheric roj av.

Йпаунпайп (downpipe) - qhov no yog cov yeeb nkab uas pab kom tshem tawm cov pa tawm ntawm lub cav mus rau lub cav, yog li tig nws. Txuas ncaj qha mus rau lub tso pa tawm manifold thiab turbine.

Downpipe zoo li cas?

Lub downpipe tsuas yog ib tug 40-60 cm ntev yeeb nkab uas pib txoj cai tom qab lub turbine thiab txuas mus rau lub tso pa system.

Feem ntau tsuas yog siv rau hauv tsheb nrog turbo engine. Txij li thaum lub turbine nyob nruab nrab ntawm lub manifolds ntawm lub taub hau thiab lub tso pa tawm, thiab mus txuas rau lub tso pa system, koj xav tau ib tug yeeb nkab uas txo cov pa kab.

Qhov no tsis yog qhov ua rau muaj kev nkag siab zoo, tab sis ntawm cov tsheb aspirated, manifolds uas pib ntawm lub taub hau txuas mus rau cov yeeb nkab tso rau hauv qab ntawm lub tsheb.

Nyob rau hauv lub tsheb nrog turbochargers, ib seem ntawm cov yeeb nkab (downpipe) yog xav tau los txuas lub turbine mus rau tus so ntawm cov pa system, uas yog nyob rau hauv qab ntawm lub cav, uas yog vim li cas nws thiaj li hu ua downpipe.

Nyob rau hauv cov yeeb nkab no feem ntau yog ib tug catalyst los yog particulate "filter" (nyob rau hauv cov ntaub ntawv ntawm diesel xyaw). Yeej, nws yog ib qho kev tivthaiv nrog kev lim dej uas ua haujlwm kom txo qis cov pa tawm.

Nyob rau hauv daim duab hauv qab no, koj tuaj yeem pom cov yeeb nkab hauv qab tau haum raws li tus qauv ntawm lub tsheb, uas tau raug txiav qhib kom pom cov sab hauv.

Nws nyob qhov twg?

Lub downpipe yog nyob nruab nrab ntawm lub turbocharger thiab lub tso pa tawm thiab feem ntau muaj (nyob ntawm seb lub tsheb hom) ib tug pre-catalyst thiab / los yog lub ntsiab catalyst thiab ib tug oxygen sensor. Qhov loj downpipe txoj kab uas hla muab kev ua tau zoo dua thiab lub suab zoo dua.

Downpipe hauv lub cav thiab turbocharger lub lag luam

Ob lub turbocharger thiab lub cav yog qhov tseem ceeb twj. Hauv qhov no, tus nrog sib ntaus loj tshaj plaws ntawm txhua lub twj tso kua mis yog qhov txwv. Txo cov pa nkev tawm hauv lub tsheb cav tuaj yeem tsim hluav taws xob.

Qhov qis permeability ntawm cov pa tawm ua rau nws ua haujlwm hnyav dua los ntxuav lub tog raj kheej rau lub voj voog tom ntej, siv lub zog uas siv tsis tau los txav lub tsheb. Kev txwv kev noj haus txwv tsis pub sib xyaw ntawm huab cua thiab roj uas tso cai rau combustion, yog li txwv lub zog.

Qhov tseem ceeb ntawm downpipe

Raws li peb tau sib tham ua ntej lawm, cov roj av tau yooj yim thiab ntau dua xa mus rau qhov chaw turbine, lub zog ntau npaum li cas lub cav muaj peev xwm xa tau. Qhov loj dua ntawm cov nplawm caj dab yog tias nws muab tsawg tsis kam rau cov roj cua kom zoo dua li cov nplawm tus caj dab, uas tso cai rau lub tshuab cua nrawm nrawm nrawm dua thiab txhim tsa ntau lub siab.

Vim li cas lub downpipe tseem ceeb?

Downpipe raug teeb meem

Cov teeb meem tseem ceeb nrog downpipes yog lawv cov fabrication. Nws tsis pub leejtwg paub tias txhua lub tsheb tshwj xeeb hauv nws cov qauv, txawm tias ob tus qauv zoo ib yam, tab sis nrog cov cav sib txawv, muaj cov txheej txheem sib txawv ntawm lub cav sab hauv. Hauv qhov no, downpipes yuav tsum tau ua kom nkhaus hauv cov dav hlau sib txawv kom haum lawv kom raug.

Nyob rau hauv cov txheej txheem ntawm kev tsim tawm xws li nozzles, ripples thiab tsis xwm yeem tuaj yeem tshwm ntawm sab hauv ntawm lub nozzle ntawm khoov cov ntsiab lus. Cov kev tsis xwm yeem no ua rau muaj kev kiv thiab cua hlob, uas txo cov dej ntws ntawm cov roj tsheb kom tas. Kev ua haujlwm downpipes yog smoother uas tsis muaj qhov sab hauv, yog li muab cov pa hluav taws xob zoo dua thiab muaj zog ntau dua los ntawm cov turbocharger.

Qhov twg downpipe siv

Hom ceg kav dej no yog siv rau kev kho tus kheej ntawm lub cav, thaum lub tshuab cua nkag thaum pib, thiab lawv xav ua kom nws muaj cua tshuab.

Lub turbine yuav tsum tau untwisted qee yam, raws li, yuav tsum tau muaj cov pa tso pa tawm, tab sis qhov twg kuv tuaj yeem tau txais nws yog tias nyob rau hauv cov txheej txheem tsuas muaj ib qho kev tso pa tawm thiab tom qab ntawd cov yeeb nkab tso nws tus kheej? Nws yog nyob rau hauv cov xwm txheej uas lub downpipe yog ntsia, uas yog, lub tso pa manifold yog tiav lawm (feem ntau yog ib tug "kab laug sab" yog ntsia), los ntawm cov downpipe twb disverts tso pa roj rau lub turbine thiab tig nws.

Kuv lub tsheb puas muaj lub pas dej ua ke?

Yog hais tias koj lub tsheb yog turbocharged (diesel los yog petrol), nws yuav tsum tau nruab nrog ib tug downpipe (nco ntsoov, qhov no yog ib tug txuas raj).

Yog tias koj lub tsheb nyob hauv huab cua, tsis txhob nruab ib lub downpipe rau nws, vim nws tsis muaj txiaj ntsig. Cov tsheb tiam tshiab tam sim no yuav luag ib txwm siv turbocharged, yog li lawv twb muaj tus thawj downpipe raws li tus qauv. 

Nrog rau InoxPower downpipe, koj tuaj yeem tau txais kev pom zoo hauv lub zog, siab dua nrog kev yooj yim ECU remapping, nrog rau kev txhim kho suab, qhov thaiv tiag tiag uas tsis ua rau koj lub cav nrov.

Thaum twg koj yuav tsum hloov koj lub downpipe?

downpipe tuning

Feem ntau cov downpipe nrog lim yog ib qho hnav-tiv taus tivthaiv, tshwj xeeb tshaj yog qhov no tshwm sim rau cov cav tov diesel uas DPF nyiam txhaws thiab feem ntau nyuaj kho lub sijhawm. Hauv phau ntawv qhia no, peb yuav tsis mus rau hauv cov ntsiab lus ntawm vim li cas qhov no tshwm sim. Ntawm no peb yuav tsom mus rau qhov laj thawj vim li cas koj feem ntau hloov los ntawm cov khoom lag luam downpipe mus rau ib qho kev sib tw, uas yog ua kom lub zog.

Yog tias koj ua txhua yam kev txhim kho kom muaj lub zog ntawm lub tsheb nrog lub tshuab hluav taws xob (Kuv nco ntsoov koj tias cov no yog cov kev hloov pauv uas yuav tsum tau ua tsuas yog rau kev khiav hauv lub kaw lus kaw), thawj kauj ruam yog "daim ntawv qhia" classic rau hauv chav tswj. .

Los ntawm nws tus kheej, qhov no yuav yog qhov kev hloov pauv txaus kom tau txais thawj qhov nce hauv lub zog.

Tab sis yog tias koj xav kom tau txais qhov kev ua tau zoo tshaj plaws ntawm koj lub cav yam tsis muaj kev cuam tshuam nrog lub turbocharger, pistons, txuas cov pas nrig, lossis lub hwj chim pob, thiab TSIS TXAUS SIAB, ces muaj cov kauj ruam tom ntej, feem ntau hu ua "theem 2."

Theem 2 qhov tseem ceeb muaj xws li kev txhim kho ib qho kev sib tw downpipe, kev noj thiab ib daim ntawv qhia tshwj xeeb (lub sij hawm theem 2 yog generic, qee zaum nrog rau lwm yam kev hloov kho).

Cov kab hauv qab yog hloov lub dowpipe nrog ib qho kev ua kis las. INOXPOWER. Ib kauj ruam yooj yim uas, txawm li cas los xij, radically hloov qhov tshwm sim, tso cai rau muaj zog ntxiv.

Tab sis nws tsis nres ntawd ...

Cov txiaj ntsig ntawm downpipe tuning

Downpipe tuning yuav coj ntau yam teebmeem, tag nrho raws li qhov txo qis ntawm cov pa rov qab vim yog lub downpipe txoj kab uas hla loj dua:

• txo cov pa cua kub, txo cov cua sov load
• txo cov pa roj backpressure, tsawg mechanical kev nyuaj siab
• Kev tsim khoom nce
• siab dua torque
• zog nce
• kev tsav tsheb zoo tshaj plaws
• zoo suab, kuj hnov ​​nyob rau hauv lub tsheb

Cov Lus Nug thiab Cov Lus Teb:

Dab tsi yog qhov downpipe rau? Downpipe - lus "downpipe". Xws li ib tug khoom yog ntsia nyob rau hauv lub tso pa system. Nws txuas lub turbine rau lub tso pa tawm yog tias tus qauv muffler nyob rau hauv lub turbocharged internal combustion engine tsis tiv nrog txoj hauj lwm.

Downpipe ntxiv zog npaum li cas? Nws nyob ntawm cov yam ntxwv ntawm lub cav turbocharged. Yog tsis muaj chip tuning, lub zog nce yog 5-12 feem pua. Yog hais tias peb kuj nqa tawm nti tuning, ces lub hwj chim yuav nce siab tshaj 35%.

Qhov twg yog Downpipe ntsia? Feem ntau lawv tau nruab rau ntawm tubed motors kom tshem tawm cov pa tawm sai. Qee qhov teeb tsa zoo li no rau ntawm lub tshuab ua kom lub cev muaj zog.
