Txhua xyoo, automakers sim txhim kho tsis yog tsuas yog tsim, tab sis kuj yog cov yam ntxwv ntawm lub tsheb. Kev txhim kho muaj feem xyuam rau txhua yam, nrog rau lub cav. Tam sim no tau ntau xyoo lawm, ntau hom superchargers tau teeb tsa rau ntau lub tsheb. Lawv tau tsim los txhim kho lub zog thiab lub zog ntawm lub cev muaj zog. Muaj ob hom tshuab tshuab. Qhov no yog compressor thiab turbine. Dab tsi zoo dua? Qhov txawv, qhov zoo thiab qhov tsis zoo ntawm ob chav nyob - hauv peb tsab xov xwm.
Destination
Raws li peb tau hais ua ntej lawm, cov khoom siv no tau tsim los txhim kho lub cav ua haujlwm. Lawv lub luag haujlwm yog yuam cov huab cua mus rau hauv cov khoom noj khoom haus ntawm lub cav combustion sab hauv. Cov pa oxygen nkag mus rau hauv lub chamber hauv cov ntim loj, yog li ua kom rov qab thiab ua haujlwm tau zoo. Tab sis kom paub seb qhov twg zoo dua -compressor lossis turbine, xav txog txhua qhov kev sib cais.
Compressor nta
Nov yog lub tshuab hluav taws xob supercharger uas los ntawm ntau hom:
- Screw.
- Rotary.
- Centrifugal.
Compressors tau pib nruab rau ntawm lub tsheb ntev ua ntej qhov tshwm sim ntawm turbines - kwv yees li ntawm 50-60s ntawm lub xyoo pua xeem. Tam sim no, xws li units yog xyaum tsis siv. Cov neeg tsim khoom tshiab tshaj plaws rau nruab compressors yog Mercedes thiab Range Rover.
pros and cons
Qhov twg zoo dua - compressor lossis turbine? Tsheb nrog compressor muaj ob peb qhov zoo:
- Kev ntseeg. Cov cuab yeej ntawm cov cuab yeej no yog qhov yooj yim heev, thiab yog li kev sib cais tau xyaum tsis suav nrog.
- Tsis poob thaum lub zog nrawm.
- Tsis xav tau ntxiv txias thiab lubrication.
- Tsawg zaus ntawm overheating.
- Cov khoom siv cav loj.
Teb cov lus nug ntawm dab tsi yog qhov zoo dua - compressor lossis turbine, nws tsim nyog xav txog qhov tsis zoo ntawm thawj lub tshuab. Lub ntsiab tsis zoo yog qhov ua haujlwm qis ntawm lub compressor. Yog li, chav tsev tuaj yeem nce lub zog tsis pub ntau tshaj 10 feem pua. Niaj hnub no, qhov no yog qhov taw qhia me me, rau lub hom phiaj ntawm cov tuam txhab lag luam tsis txhob twv kom nyuaj rau kev tsim lub tsheb thiab ua rau nws kim dua.
Thiab tag nrho vim tias lub tshuab yog tsav los ntawm lub crankshaft pulley. Ntawd yog, qhov ua tau zoo ntawm lub compressor ncaj qha nyob ntawm qhov kev sib hloov ntawm lub pulley. Thiab txij li lub turnovertxhua lub cav raug txwv, qhov ua tau zoo ntawm cov tshuab supercharger yuav tsis siab dhau.
Turbocharger nta
Qhov twg zoo dua - compressor lossis turbine? Tam sim no xav txog cov yam ntxwv ntawm lub turbocharger. Xws li ib tug mechanism tsis nyob ntawm tus crankshaft. Nws ua haujlwm ntawm lwm txoj hauv kev.
Lub impeller tig vim yog stroke ntawm cov pa pa. Lub turbine muaj qhov txias thiab qhov kub. Gases txav mus rau tom kawg, yuam lub impeller ntawm qhov txias ua haujlwm. Tus naj npawb ntawm cov kiv puag ncig ib feeb yog ntau zaus ntau dua li ntawm cov neeg kho tshuab supercharger. Li no qhov kev ua tau zoo. Raws li kev xyaum qhia, vim yog supercharging, koj tuaj yeem ua kom lub zog nce mus txog 40 feem pua, nrog rau qhov tsis muaj peev txheej poob.
Yog li, qhov zoo ntawm lub turbine yog nws qhov kev ua tau zoo. Tsis tas li ntawd, muaj peev xwm ntawm nti tuning, uas tso cai rau koj los ua kom lub zog ntawm lub cav los ntawm ob peb feem pua. Tab sis qhov shortcomings yog pom tseeb.
Raws li lub cav fais fab nce, yog li cov load ntawm lub crank mechanism. Nws ua raws li cov ntsiab lus yuav tsum ntseeg tau. Tab sis qhov no tsis yog ib txwm muaj, tshwj xeeb tshaj yog nyob rau hauv chipped internal combustion engines. Feem ntau cov crankshaft tsis tiv taus xws li loads, thiab yog li ntawd lub cev muaj zog cov peev txheej raug txo kom tsawg.
Cov qauv rau turbocharged xyaw suav tias yog ib qho peev txheej ntawm 150 txhiab kilometers (yog tias peb suav nrog TSI niaj hnub). Tsis tas li ntawd, lub turbine feem ntau nyiam noj roj. Nws noj yog los ntawm ib liter ib 10 txhiab kilometers (thiab qhov no yog nyob rau hauv lub engine ua hauj lwm). Tsis tas li ntawd, cov roj yuav tsum yog cov khoom zoo. Txwv tsis pub, cov peev txheej cavyuav tsawg dua.
Cav nrog lub compressor tsis muaj qhov teeb meem no. Lawv tsis xav tau roj thiab tsis thauj lub cav ntau npaum li. Raws li, txhua lub tshuab compressor yuav muaj peev xwm ntau dua li lub turbocharged.
Tab sis, raws li kev txheeb cais qhia, ntau thiab ntau cov tuam txhab nyiam siv hom thib ob ntawm kev txhawb nqa. Qhov no yog tshwj xeeb tshaj yog muaj tseeb rau diesel units. Lawv muaj cov qauv ruaj khov dua, thiab kev khiav hauj lwm ceev tsis siab npaum li cov roj av. Txawm li cas los xij, tom qab 250 txhiab kilometers, teeb meem tshwm sim nrog lawv.
Yuav xaiv twg zoo dua?
Yog li, cia peb xaus. Dab tsi yog qhov zoo dua - txhua yam compressor lossis turbine? Tsis muaj ib lo lus teb rau lo lus nug no. Txhua tus xaiv raws li cov kev xav tau thiab kev nyiam. Yog tias cov peev txheej yog qhov tseem ceeb, koj yuav tsum txwv koj tus kheej rau lub compressor thiab txaus siab nrog 10 feem pua ntawm lub zog ntxiv. Tab sis yog tias koj xav tau qhov siab tshaj plaws rov qab los, qhov kev xaiv no yuav pom tseeb - tsuas yog lub turbine xwb. Txawm li cas los xij, koj yuav tsum nco ntsoov tias lub cav zoo li no tuaj yeem "kawg" tam sim ntawd - nws yuav xav tau kev kho lub turbine lossis KShM qhov chaw.
Xav txog qhov kev xaiv ntawm kev sib tw. Dab tsi yog qhov zoo dua ntawm VAZ - compressor lossis turbine? Ntau tus xaiv qhov kev xaiv thib ob, txij li cov peev txheej ntawm VAZ xyaw twb tsis tseem ceeb.
