Tshawb nrhiav Kev Txhim Kho Ntawm Diesel Generator Intake System

1, Cummins lub tshuab hluav taws xob teeb tsa cov cua nkag siab

Turbocharging yog lub tshuab cua compressor uas siv cov huab cua tso pa tawm los ntawm lub tshuab hluav taws xob sab hauv los tsav nws.Cov cuab yeej supercharging tuaj yeem txhim kho huab cua huab cua nkag mus rau hauv lub tog raj kheej los ntawm compressing cua xav tau rau roj combustion nyob rau hauv cov xwm txheej ntawm tib lub ntim ua hauj lwm thiab ceev ntawm lub diesel generator , thiab tom qab ntawd txhim kho lub zog ceev ntawm lub tshuab hluav taws xob diesel.Cov txheej txheem ntawm lub supercharger tsis tsuas yog suav nrog lub cev supercharger, intercooler, supercharger txias pipeline hardware lub cev, tab sis kuj suav nrog lub supercharger siab sensor, cua ntws ntsuas, ceev sensor, detonation sensor, roj injector, ignition coil thiab lwm yam hluav taws xob sensors rau teeb liab. tawm tswv yim.Turbocharger lub cev tseem ceeb suav nrog cov pa tawm bypass valve thiab lub qhov nkag siab lub siab nyem valve, hluav taws xob sensor tawm tswv yim teeb liab, xws li EMS system los ntawm kev txiav txim siab ceev tus neeg teb xov tooj xav tau lub tshuab hluav taws xob diesel, thiaj li tso tawm lub zog ntawm lub luag haujlwm, tswj lub supercharger kev kawm ntawm pa bypass valve qhib, kom ntau tso rau hauv lub tso cua turbine sab, ua rau kom lub siab, ua rau lub inlet siab kom ua tiav cov hom phiaj, nce diesel generator zog.Thaum EMS tau txais lub tsheb los ntawm txhua lub tshuab hluav taws xob tsis tas yuav txhawb nqa lub zog, lub sijhawm no EMS tso tawm cov dej ua haujlwm siab piv yog 0, tso tawm los ntawm cov raj xa dej hla dhau, lub supercharger tsis muaj zog ntxiv rau kev noj;EMS kuj tseem tswj tau qhov qhib ntawm qhov nqus siab nyem valve ntawm lub supercharger kom sai txo qhov nqus tau siab mus rau qib tsis muaj zog thiab lub tshuab hluav taws xob diesel rau lub hom phiaj lub zog.Cov yam ntxwv tseem ceeb ntawm supercharger txiav txim siab qhov siab tshaj plaws supercharger siv.Cov yam ntxwv tseem ceeb ntawm lub supercharger suav nrog qhov siab tshaj plaws uas tau tso cai los ntawm supercharger thiab cov kab hluav taws xob ntawm lub supercharger.Thaum xaiv ib hom supercharger rau lub tshuab hluav taws xob diesel, cov yam ntxwv ntawm lub tshuab hluav taws xob tau txiav txim siab.Raws li qhov siab tshaj plaws tso cai ceev ntawm lub turbocharger thiab surge kab ntawm lub turbocharger, qhov siab tshaj plaws turbocharging piv ntawm txhua lub zog ceev yog calibrated rau diesel generator lub rooj ntev zaum calibration.Tom qab lub calibration ntawm lub tshuab hluav taws xob diesel, qhov kev tswj kev taw qhia ntawm turbocharger tau txiav txim siab.

2, Cummins   Lub tshuab hluav taws xob teeb tsa lub sijhawm sib txawv ntawm lub valve

Thaum qhov ceev thiab thauj khoom ntawm lub tshuab hluav taws xob diesel hloov, qhov ntim ntim, qhov ntim tawm, qhov nkag thiab cov pa tawm nrawm nrawm, lub sijhawm ntawm kev nqus thiab tso pa tawm, cov txheej txheem combustion hauv lub tog raj kheej sib txawv, thiab qhov yuav tsum tau ua ntawm lub valve theem thiab lub valve nqa yog kuj txawv.Piv txwv li: thaum qhov ceev yog siab, lub inlet ntws tshaj tawm yog siab thiab lub zog inertia loj, yog li nws cia siab tias lub inlet valve yuav qhib ua ntej thiab kaw tom qab, thiaj li ua kom tag nrho cov inertia ntawm inlet. ntws thiab them cov cua tshiab rau hauv lub tog raj kheej kom ntau li ntau tau;Ntawm qhov tsis sib xws, thaum lub tshuab hluav taws xob diesel ceev yog qhov tsawg, qhov nkag ntawm qhov dej ntws tsawg, thiab lub zog inertia me me.Yog hais tias lub inlet valve lig kaw lub kaum sab xis loj heev, cov roj tshiab uas tau nkag mus rau hauv lub tog raj kheej yuav raug nyem tawm ntawm lub tog raj kheej los ntawm lub piston upward nyob rau hauv lub compression stroke.Ib yam li ntawd, yog tias lub valve qhib dhau ntxov, vim tias lub piston nce siab, nws yooj yim rau nyem cov pa tso rau hauv cov yeeb nkab, kom cov pa seem seem hauv qhov nqus tau nce, tab sis cov roj tshiab tau txo qis, yog li ntawd. tias lub tshuab hluav taws xob diesel tsis ruaj khov.Raws li qhov tshwm sim, tsis muaj qhov chaw ruaj khov valve theem uas muab kev pom zoo rau cov tshuab hluav taws xob diesel ntawm ob qho tib si siab thiab qis.Lub sijhawm sib txawv ntawm lub sijhawm (VVT) tuaj yeem txhim kho cov roj kev lag luam, kev ua haujlwm ntawm lub zog thiab kev ua haujlwm ruaj khov ntawm cov tshuab hluav taws xob diesel nyob rau hauv ntau qhov ceev thiab thauj khoom los ntawm kev hloov pauv theem ntawm cov tshuab hluav taws xob diesel, thiab txo cov pa phem.

3, Cummins generator teeb lub tshuab hluav taws xob valve

Diesel generators ntawm qhov sib txawv ceev.Cov kev xav tau rau kev mus ncig valve txawv heev.Ntawm qhov ceev ceev, vim tias qhov ntim ntim me me, yog tias lub valve mus ncig yog qhov loj, nws yuav tsis tuaj yeem tsim kom txaus kom txaus siab tsis zoo, lub injector tsis tuaj yeem sib xyaw nrog cov pa nqus pa tom qab txhaj tshuaj, uas ua rau muaj kev sib xyaw ua haujlwm tsawg, Tsawg ceev torque yuav raug txo kom tsawg, thiab emissions kuj yuav nce.Hauv qhov no, yuav tsum siv lub valve me me.Vim lub me me mus ncig teb chaws, qhov kev nqus tsis zoo siab yog nce, thiab qhov tshwm sim ntawm cov vortices loj tuaj yeem ua tiav qhov sib xyaw kom tau raws li kev ua haujlwm ntawm lub tshuab hluav taws xob diesel ntawm qhov ceev.Thaum muaj kev kub ceev, qhov xwm txheej yog qhov txawv.Nyob rau lub sijhawm no, qhov ntim tau ntau heev.Yog hais tias lub valve mus ncig me me dhau lawm, qhov kev tiv thaiv kev noj qab haus huv yuav loj heev kom nqus tau pa txaus, yog li cuam tshuam rau kev ua haujlwm ntawm lub zog.Yog li ntawd, ntawm kev kub ceev, nws yog ib qho tsim nyog yuav tsum muaj lub valve loj mus ncig, thiaj li yuav tau txais qhov zoo tshaj plaws valve xav tau.Txhawm rau txo cov roj noj, BMW lub qhov hloov kho lub valve tswj cov huab cua mus rau hauv lub tshuab hluav taws xob diesel tsis yog los ntawm lub tshuab hluav taws xob tab sis los ntawm kev hloov kho nqa ntawm qhov nqus valve.Los ntawm txhais tau tias ntawm ib qho hluav taws xob adjustable eccentric ncej, qhov kev txiav txim ntawm lub camshaft ntawm cov menyuam valve siab pas nrig yog hloov los ntawm ib tug nruab nrab qib, yog li tsim ib tug adjustable intake valve nqa.Lub throttle tsuas yog siv thaum pib thiab thaum muaj xwm txheej ceev.Nyob rau hauv tag nrho lwm yam kev khiav hauj lwm tej yam kev mob lub throttle yog tag nrho qhib nrog me ntsis throttling.Lub tshuab hluav taws xob valve ua tiav qhov zoo tshaj plaws sib npaug ntawm lub zog torque tso zis ntawm lub tshuab hluav taws xob diesel nyob rau hauv cov xwm txheej ceev sib txawv los ntawm kev hloov tsis hloov ntawm lub valve stroke.

Kev vam meej tas mus li ntawm lub neej niaj hnub no kuj ua rau muaj ntau yam tsis zoo rau ib puag ncig uas peb nyob.Nyob rau hauv cov xwm txheej zoo li no, nyob rau hauv lub neej yav tom ntej txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis ntawm kev tsim cov pa roj carbon tsawg, kev txuag hluav taws xob, kev tiv thaiv ib puag ncig tau maj mam dhau los ua qauv, kev txhim kho ntawm lub tshuab hluav taws xob diesel generator cua nkag qhov system tshawb fawb, tsis tsuas yog pab. peb ntxiv kom nkag siab txog kev txhim kho tsis tu ncua ntawm lub tshuab hluav taws xob diesel generator cua nkag qhov system, thiab rau kev kawm yav tom ntej ntawm lub tshuab hluav taws xob cua nkag qhov system kev tshawb nrhiav ua lub luag haujlwm, qhov tsis zoo ntawm kev siv roj ntau thiab cov pa phem ntau ntawm cov tshuab hluav taws xob tuaj yeem daws tau los ntawm kauj ruam.
