Uas engine yog zoo dua: 16-valve, los yog 8-valve? Cav qhov chaw, kho, kev specifications

Kawm tsheb forums, koj muaj peev xwm feem ntau nrhiav tau cov lus nug no. Nws koom motors thiab pab kiag li lawm. Heev npaum li cas sib cav tswv yim li cas yam ntawm engine yog zoo dua - ib tug 16-valve, los yog 8.

Cov nyob mus ib txhis sib cav tswv yim

Ib nrab ntawm lub tsheb tswv paub tseeb 8V qauv twb dhau caij nyoog. Thiab yuav ib lub tsheb nrog rau qhov no cav hnub no - nkim nyiaj. Tab sis lub 16-valve powerplant - yog lwm heev teeb meem.

Qhov thib ob ib nrab ntawm cov xeev uas rau tag nrho nws cov virtues, xws units yuav tsum tau ntau xim, kim kim kom muaj, xav zoo zoo roj. Thiab yog hais tias xws li ib tug lub cev muaj zog yuav txiav txim siab tawm ntawm lub cev, ces nws yog yooj yim los mus dhau rau lub seem. Tshwj xeeb tshaj yog thaum koj xav txog ntau npaum li cas lub cav, lub 8-valve engine nyob rau hauv no hwm yog zoo npaum li cas.

Peb sim kom paub tseeb seb yog dab tsi yog qhov zoo tshaj plaws, xav txog tag nrho cov pros thiab cons ntawm txhua tsav. Txawm tias yeej hais tias ib yam ntawm cov ob units yog superior, nws yog tsis yooj yim sua. Ib txhia xav yuam installation yog txhim khu kev qha thiab unpretentious, lwm leej lwm tus xav tau hwj chim, muaj kev kawm siab, tus lag luam. Raws li yuav pom, qhov sib txawv pawg ntawm cov neeg tsav tsheb ua rau kev sib tw txawv. Thiab cov motors txawv los ntawm ib lwm.

Ob peb kev tivthaiv

Nyob rau hauv kev cov ntsiab lus uas, 8 thiab 16-valve nrog combustion xyaw txawv tiag txaus. Tiam sis tag nrho cov sib txawv nruab nrab ntawm lawv yog nyob rau hauv sab qaum kev ib thereof - nyob rau hauv lub cev muaj zog lub taub hau. Ntawm no yog cov camshafts. Qhov no yog muab zais thiab lub ntsiab tsim feature.

Thiab rau cov neeg uas xav paub uas engine yog zoo dua - 16-valve los yog 8, nws yuav tsum tau hais tias ib yam ntawm cov chav tsev yuav ua tau ib qho kev xaiv nyob rau hauv 8V thiab 16V. Piv txwv li, nyob rau feem ntau lub tsheb los ntawm AvtoVAZ xyaw yog heev uas zoo sib xws rau txhua tus lwm yam raws kev nyob rau hauv cov ntsiab lus thiab tswv yim ua. Ib tug thiab tib yam engine thaiv yuav txawm peem rau nrog txawv lub tog raj kheej taub hau raws li ib tug nkaus xwb los yog nrog ob tug camshafts.

8V xyaw

Lub hwj chim no unit muaj tsuas yog ib camshaft. Nws saib xyuas cov hauj lwm ntawm lub txhaj system thiab tso. Nyob rau hauv kev tshawb xav, qhov no yog raws li nram no. Tus qauv ntawm txhua lub tog raj kheej muaj ob tug li qub. Ib tug ntawm lawv yog npaj rau kev pub mis roj sib tov nyob rau hauv lub combustion chamber. Nws yuav qhib thaum cov roj mov rau tus kheej kheej. Qhov thib ob ua hauj lwm pab mus tso zis tso pa. Qhov no lub caij qhib thaum cov roj sib tov twb burnt, thiab nws tsuas yog tsim nyog los tso rau hauv lub nkev mus rau hauv lub tso system. Qhib / kaw ntawm lub qub yog tom camshaft. Nws tau tapered nws yog xim hlau feem. Thaum tus ncej rotates, nws presses cov feem ntawm lub valve. Nws yuav qhib los yog kaw.

Yog li, txhua lub tog raj kheej muaj ob tug li qub. Txij li thaum lub tog raj kheej nyob rau hauv tus txheej txheem hom xyaw 4, lub ntsiab 8 yog tau. Ntawm cov hoob kawm, tus 4-lub tog raj kheej engine - qhov no yog tsis yog tib tsev, tsuas ntau heev. Muaj 6- thiab 8 thiab 12-lub tog raj kheej tshuab. Tab sis cov no nrog combustion xyaw - ib tug rarity rau cov tsheb. Lub freight tsheb 8-lub tog raj kheej tshuab ntau yam. Piv txwv li, lub cav YaMZ 238. Nws muaj 16 li qub. Tab sis nyob rau hauv qhov tseeb, rau txhua lub tog raj kheej muaj tsuas yog ib tug rau inlet thiab hluav taws xob. Lub hwj chim ntawm no unit yog hom twg los ntawm 180 mus 240 hp nrog ib tug ua hauj lwm ntim ntawm 14,8 liters.

Qhov zoo ntawm xyaw 8V

Yuav kom teb kom yog yog rau lo lus nug ntawm yog dab tsi cav yog zoo dua - ib tug 16-valve, los yog 8, koj yuav tsum xav txog qhov zoo thiab qhov tsis zoo. Peb pib nrog cov zoo muaj los ntawm lub thib ob hom engine. Tus thawj kom zoo dua - nws yog simplicity. Cov yooj yim chav tsev yog txheej txheem, lub zoo dua rau tus tswv tsev. Tus tsim ntawm cov tsoos motors tau raug kuaj los ntawm lub sij hawm. Lub system nws tsuas muaj tib camshaft. Nyob rau ib lub tog raj kheej muaj ob li qub.

Neeg kho tshuab cov rooj sib txoos me ntsis, cav qhov chaw npaj meej muaj nyob thiab pheej yig. Yog li ntawd, cov kho nqi yog yooj yim dua thiab pheej yig dua. Qhaj ntawv ntawm lub lash - nws kuj yuav ntaus nqi mus rau txoj hauj lwm zoo. Qhov tseeb ua qhov kev siv ntawm ib tug 8-valve chav tsev txawm yooj yim. Tab sis tus tsim muab rau ib tug cov neeg kho tshuab tappets, thiab yog ob qho tib si ib tug ntxiv thiab ib tug rho tawm. Nws yog zoo hais tias qhov no mechanism yog yooj yim tshaj hydraulic lifters. Yog li ntawd, los ua ke yuav muab tau yooj yim hloov los yog kho thaum uas tsim nyog.

Thiab tsis tau - nyob rau hauv ICE cov ntaub ntawv teev pistons, uas nyob rau breakage sij hawm siv yuav tsis tau raws li nrog lub qub. Qhov no yog ib tug loj ntxiv, tshwj xeeb tshaj yog thaum koj xav txog hais tias tom qab xws li ib tug tsim nyog cav overhaul. Tus nqi ntawm xws "Library" yog 35-40 txhiab. Rubles. Tsis tas li ntawd, qhov zoo xws li cov "omnivorous" unit. Nws twb yuav luag tsis yuav tsum tau rau cov roj thiab semi-synthetics txig digests. Undemanding cav thiab roj (ntawm cov hoob kawm tsis pub dhau tsim nyog txwv). Nws yuav nquag ua hauj lwm txawm nyob rau hauv qib A92 roj av.

Koj yuav tau nco ntsoov tus nqi ntawm cov tswv cuab. Kho nqi yog comparatively kim, thiab cav qhov chaw yuav tsis tau yooj yim mus nrhiav tau thaum nws los txog rau xyaw AvtoVAZ. Tsis tau compact qhov ntev yuav tsum distinguished ntawm cov pros. Ib camshaft, ntsig txog, rau sab qaum feem yog tsawg tshaj li 16-valve embodiment. Nyob rau hauv cov ntaub ntawv ntawm kev kho yog yooj yim npaum li tau mus rau lub generator, oob khab thiab lwm yam khoom. Nrog rau qhov no kuv pom zoo rau sawv daws yuav leej twg muab tso rau lub 16-valve engine rau lub classics.

Tsis zoo 8V ICE

Tus thawj tsis zoo - ib tug kuj me me ntawm lub hwj chim. Tej zaum koj yuav tau txais xwb 15-20%. Yog hais tias lub sau ua ib pawg hwj chim ntawm 100 horsepower, nws yog cia li 15-20 hp Thaum lub inlet thiab qhov hluav taws xob tsim ob li qub ib lub tog raj kheej. Qhov no txhais tau hais tias kom tsawg thiab tso dab yog qeeb qeeb. Thiaj tau nyob rau hauv no high-revving unit yuav tsis ua hauj lwm. Mus tom ntej. ICE 8V muaj ntau dua kev noj roj. Kev noj yog ntau dua vim lub qeeb qeeb mus "txhaj-ntsoos ntsoos." Tsav muaj zog thawb lub tso gases los ntawm ib tug tib qhov hluav taws xob neeg.

Thaum kawg, siab suab nrov, tshwj xeeb tshaj yog thaum tsav tsheb nyob speeds siab. Txij li thaum ib tug cov neeg kho tshuab voom, nws yuav tsum tau tas li haum. Thaum lub sij hawm kev lag luam, zus tau tej cov lawv yog tsim, uas muaj khoob. Vim hais tias ntawm lawv, efficiency ntawm lub fais fab nroj tsuag decreases, thiab lub cev muaj zog pib ua suab nrov. Li no, yam tsis zoo zoo los ntawm kev siv ntawm cov neeg kho tshuab plungers. Tsis tau muaj ntau yam tsis zoo li feem ntau kho valve clearances. Nws yog tsim nyog tias lub cav sau zoo dua, thiab muaj tsis muaj overspending ntawm cov roj. Raws li ib tug tshwm sim, 8-valve engine - yog ib tug txhim khu kev qha, tsis tshua muaj txij nkawm, ib qho yooj yim ua hauj lwm rau tej roj thiab roj system. Tab sis es tsis txhob peb tau txais cov impossibility ntawm cov kev ruaj khov lag luam ntawm kev kub ceev, uas tsis muaj zog thiab cov suab nrov. Yog hais tias peb xav txog yuav ua li cas npaum li cas lub cav, ces cov disadvantages yuav kaw koj ob lub qhov muag. Nyob rau motors nrog ib tug layout 8V ntse tsav niaj hnub no. Tab sis muag lawv tsis muaj.

16V engine

Raws li cov kev yog ib feem ntawm lub sab hauv combustion engine muaj ib tug ntau nyuab qauv. Lub Tog Raj Kheej lub taub hau, tab sis ob camshafts ntsia tau rau hauv nws. Lawv sib nrauj nyob rau hauv txawv kev qhia, li ntawd, cov xov tooj ntawm li qub zog. Muaj tsis muaj ob, tab sis plaub li qub ib lub tog raj kheej. Ob tug ntawm lawv yog tsim rau cov roj kom tsawg. Lwm tus - nyob rau hauv lub qhov teeb meem.

Hais tias nws yuav muab ib tug tswv tsheb?

Tus thawj tshaj plaws txhua Vaz 16-valve - ib tug zoo peev xwm. Lub cav powered loj tus naj npawb ntawm cov roj sib tov thiab ho ceev los ntawm lub tog raj kheej tso zis tso roj cua. Lawm, nws yog nce rau hauv lub cev muaj zog efficiency. Nws yog ua tau mus ntxiv lub peev xwm ntawm 15 mus rau 20 hp Nws yuav ua tau ntau dua, tab sis nws yog nyob rau hauv lub ntim ntawm ib tug unit. Qhov thib ob feature - lifters. Tshiab xyaw thiab qub Vaz 16V nruab nrog cov mechanisms. Vim lawv zoo dua cov valve yog pressed tiv thaiv cov camshaft. Lag luam ntawm lub cev muaj zog yog nrog los ntawm ib tug qis suab nrov theem.

Nws yuav tsum tau muab sau tseg tias ua hauj lwm yog tus. Tsis tas li ntawd, qhov no lub cev muaj zog sib txawv kev lag kev luam. Tej aggregates muaj ntau tus phooj ywg environmentally. Nws muaj kev tswj kom tau ntau yog cov sij hawm poob haum. Lawm, tsis ib puag ncig kev txhawj xeeb diesel xyaw, txawm hais tias YaMZ 238 kuj 16V. Tab sis raws li deb raws li YaMZ, ces nws tsis yog plaub, thiab 8 thooj voos kheej kheej. Raws li, rau txhua lub tog raj kheej ntog nyob rau hauv ob li qub.

zoo

DVS yog ntau npaum li cas haib tshaj nws txoj kev counterpart 8V. Ntawm cov hoob kawm, qhov teeb meem no yog ib qho zoo thiab muaj zog ntawm dispersal, thiab siab tshaj plaws ceev.

Txo kev noj roj, ua ntej ntawm tag nrho vim hais ntawm tus tsim nta ntawm lub engine, raws li zoo raws li vim lub fact tias lub tsheb tau sai pib khiav thiab tsis tas yuav ntev mus tig lub cev muaj zog thaum muaj kev kub ceev. Lub chaw ua hauj lwm yog nrog los ntawm ib tug me ntsis suab nrov vim lub tsim nta, raws li zoo raws li ua tsaug rau lub lash. Tsis xav kom kho li qub. Thiab qhov no yog ib tug lossis loj lub sij hawm saver.

shortcomings

Yuav luag tag nrho cov 16-klapannikom, tsis hais txog ntawm chaw tsim tshuaj paus, txawm peem rau nrog hydrojacks. Rau lawv tej kev ua hauj lwm tsim nyog zoo cov roj (dua li hluavtaws). Thiab cov khoom hnub no yog tsis pheej yig.

Tsis tas li ntawd, lub cav kus kes txog qhov zoo ntawm cov roj. Nws yog qhov zoo tshaj plaws rau chaw sam roj lub cav high-octane roj av. Thaum kawg, lub tsev muaj ib tug ntau txoj kev teeb tsa. Yog hais tias lub pistons ntsib nrog li qub, engine overhaul uas yuav tsum tau. Tus nqi ntawm cov txheej txheem - los ntawm 35 000 xuas. Tsis tas li ntawd, ICE cov ntaub ntawv yog loj nyob rau hauv loj, uas ua rau lawv nyuaj rau txij nkawm thiab kho. Nyob rau hauv tas li ntawd, manufacturers feem ntau txo nws hwj ntawm lub taub hau ntawm lub yas hau. Hais tias yog tag nrho hais tias los txog rau qhov zoo thiab qhov tsis zoo ntawm cov ob motors. Tab sis kuv yuav tsum hais tias lub qhov lag luam nrog domestic thiab txawv teb chaws manufacturers yuav tau raws li ib tug loj tus naj npawb ntawm 8V xyaw. Tab sis lawv tej chaw yog zuj zus lawm. Tam sim no txawm teem ib tug 16-valve engine rau lub classics.

Fais fab, ceev, kho chaw nres tsheb

Rau cov neeg uas nyiam xav mus nias rau tus tsuj roj kom tau lub tsheb zoo dynamic kev ua tau zoo, kev kub ceev, qhov zoo tshaj plaws kev xaiv - 16-valve engine. Nyob rau 8-valve qauv yuav tsum tau tsis nco qab lawm mus ib txhis. Tab sis kuv muaj heev noj.

Simplicity, kev cia siab, kev pab rau lawv tus kheej txhais tes

Rau cov neeg uas nyob sab nraum lub nroog thiab qhia rau dab tsi cav yog zoo dua - ib tug 16-valve, los yog 8, nrog lub hom phiaj tsav tsheb nyob rau hauv kev phem txoj kev los yog nqa ib tug trailer, ib tug tshwj xeeb kev xaiv rau tus tom kawg. Tab sis kuv yuav tsum tau siv rau cov suab nrov thiab muaj zog roj noj.

Ntshai txog lub sij hawm

Muaj ntau tsav tsheb tiag txhawj txog qhov tais nrov plig plawg nyob rau hauv xyaw 16V. Cov kev ntshai yog justified.

Tiam sis peb yuav tsum hais tias nws yog tsis raug rau txhua tus cav. Yog hais tias koj muaj lub tsev nyob rau hauv lub sij hawm, hais tias cov qub thiab cov pistons yuav puas tau ntsib, thiab yuav tsis muaj lo lus nug. Ntxiv mus, tam sim no muaj ib tug 16V units, qhov twg es tsis txhob ntawm lub sij hawm siv yog siv Circuit Court. Nws tsis tawg thiab yog ho ntev tshaj li lub siv. Yog li ntawd tsis txhob qhov zoo ntawm lub internal combustion engine 16V.
