Split iav: nws yog dab tsi, kev teeb tsa thiab kev hloov kho

2024 Tus sau: Erin Ralphs | [email protected]. Kawg hloov kho: 2024-02-19 16:10

Muaj ntau cov ntsiab lus nthuav dav hauv lub tsheb, uas tsuas yog siv tshuab tshuab lossis cov neeg uas mob siab rau kev siv tshuab paub txog. Ib qho ntawm cov khoom no yog cov khoom sib cais. Tuning enthusiasts kuj paub txog lub caij no. Cia peb kawm seb qhov no yog dab tsi thiab nws yog dab tsi.

Phase shifters thiab lawv txoj haujlwm

Feem ntau cov cav tshiab tau nruab nrog cov theem hloov pauv, uas ua rau nws tuaj yeem hloov kho lub zog ua haujlwm raws li tus naj npawb ntawm cov kiv puag ncig ntawm lub crankshaft. Qhov no yog qhov tsim nyog thiaj li tau txais lub zog siab tshaj plaws ntawm qhov dav rpm ntau dua.

Yog tias koj nqa ib phau ntawv rau kev ua haujlwm ntawm lub tsheb, ces nws yuav qhia cov yam ntxwv xws li lub zog ntawm lub cav hauv horsepower thiab lub siab tshaj plaws torque uas lub cav muaj peev xwm xa tau ntawm qee qhov crankshaft revolutions ib feeb.

Piv txwv li, tus qauv Renault Logan. Lub cav muaj peev xwm xa 170 horsepower ntawm 6 txhiab kiv puag ncig ntawm crankshaft. Qhov siab tshaj plaws torque yog 270 Nm ntawm 3250 rpm. Los ntawm cov duab no, nws yog qhov tseebtias qhov siab tshaj plaws torque tuaj yeem ncav cuag qhov nruab nrab ntawm qhov nrawm. Thiab lub zog loj tshaj plaws tsuas yog tom qab 6000 rpm. Yog hais tias xws li lub cev muaj zog yog nruab nrog ib theem shifter system, nws yuav muaj ib tug dav dav nyob rau hauv uas lub cev muaj zog yuav tsim lub siab tshaj plaws torque, thiab tsis yog ib tug uas yog tsim los rau hauv lub tsim los ntawm cov chaw tsim tshuaj paus.

Cov camshaft sib cais ua haujlwm kwv yees li tib yam haujlwm raws li theem hloov pauv. Qhov no muaj cov qauv zoo ib yam li lub camshaft. Nws tuaj yeem tig rau pem hauv ntej lossis rov qab ntawm qee lub kaum ntse ntse.

Split iav muaj nuj nqi

Ib cov pa iav mounted ntawm lub camshaft yog tsim los xa torque ntawm lub crankshaft mus rau lub camshaft ntawm lub sij hawm mechanism. Ib feem yog ib qho khoom tsis muaj qhov txav. Cov iav sib cais muaj ob yam khoom - lawv tuaj yeem txav mus rau ib leeg. Qhov kev tsim no tso cai rau koj hloov lub kaum sab xis ntawm lub camshaft yam tsis muaj kev cuam tshuam rau lub zog nro ntawm lub sijhawm siv los yog tsav saw.

Piv txwv li, qhov no ntawm VAZ cav tuaj yeem tig lub ncej los ntawm 5 ° nyob rau hauv ib qho kev taw qhia lossis lwm qhov. Ntawm no nws yog ib qho tsim nyog yuav tsum nkag siab tias nyob rau hauv txoj kev no nws tuaj yeem hloov pauv cov yam ntxwv ntawm lub cav ua haujlwm tsuas yog hauv cov hom tshwj xeeb - nyob rau sab saud lossis qis dua.

Ntau zaus, txhawm rau kom muaj zog thiab lwm yam ntxwv ntawm lub cav, lub camshaft thiab nws cov iav hloov pauv. Yog tias koj hloov lawv, koj tuaj yeem teeb tsa txawvgas faib theem. Nws kuj tseem tuaj yeem hloov lub valve lag lub kaum sab xis. Yog tias cov iav sib cais tau nruab rau ntawm lub cav tsis yog lub Hoobkas tsis hloov lub camshaft, ces tsuas yog cov sib tshooj sib tshooj tuaj yeem hloov pauv.

Nws ua haujlwm li cas?

Piv txwv li, lub torque yuav hloov ntawm 4000 rpm down, piv txwv li, mus rau 3000. Cov nyhuv no yog ua tiav los ntawm tig lub camshaft mus rau lub crankshaft. Nyob rau hauv cov ntaub ntawv no, lub sij hawm valve yog teem kom muaj ib tug me ntsis txhuas. Qhov no muaj qhov cuam tshuam los ntawm kev txo lub kaum sab xis ntawm cov khoom noj.

Tab sis koj yuav tsum nco ntsoov tias yog tias lub cav tig mus rau qhov siab tshaj plaws tau nrawm, yuav tsis muaj qhov ntom ntom ntim rau hauv nws lub tog raj kheej. Qhov no yuav tsis cuam tshuam rau qhov ceev thiab lub zog tso zis hauv qhov zoo tshaj plaws.

Tsim

Split iav muaj ob lub ntsiab - lub nplhaib iav thiab lub hub. Lawv txuas rau ib leeg nrog bolts. Lub qhov rau qhov no yog ua kom lub hub tau tig nyob rau hauv relation mus rau lub crown. Lub hub yog txuas nrog lub camshaft los ntawm ib tug yuam sij. Qhov kev kho no ua kom lub hub tig nrog rau lub camshaft.

Zoo tshaj yog vim li cas rau nruab qhov sib cais

Engine tuners hais txog ob qho laj thawj vim li cas ntau tus nruab qhov no. Nws yuav tsum tau muab sau tseg tias nyob rau hauv lub siab hais tias ib tug kev ua si camshaft yuav tsis muab ib yam dab tsi yog hais tias ib tug split camshaft iav tsis ntxiv ntsia (VAZ yuav tsis mus sai dua). Thaum sib dhos ua haujlwm rauntawm lub Hoobkas, cov chaw tsim khoom feem ntau deviates los ntawm cov ntaub ntawv qhia hauv cov duab kos. Yog li ntawd, cov tsis muaj motors tsim rau ib lub tsheb qauv txawv ntawm cov thawj sawv daws yuav. Cov kev ua yuam kev no tsis muaj ntau tshaj kaum degrees hauv txhua qhov kev taw qhia. Lawm, qhov no cuam tshuam rau lub zog yam ntxwv ntawm lub motors. Los ntawm kev txhim kho cov iav sib cais, tus tswv lub tsheb muaj lub sijhawm los kho thiab kho lub zog kom zoo raws li qhov xav tau.

Txhim kho tuned camshafts tso cai rau koj kom nce lub zog ntawm lub zog. VAZ cais iav - lwm + 5% rau lub zog yam ntxwv. Hu tau zoo heev.

Txoj kev hloov kho

Hnub no, kev ua lag luam tsheb muaj lub zog tsim rau yuav luag txhua lub tsheb los ntawm AvtoVAZ. Txhua tus qauv muaj nws tus kheej txoj kev tuning. Xav txog lub hauv paus ntsiab lus ntawm kev hloov kho ntawm tus piv txwv ntawm VAZ-2108-2112.

VAZ-2108-21099

Yog li, ua ntej ntawm tag nrho cov, cov ntsiab lus ntawm lub iav yog cim rau ntawm qhov txav tau thiab ruaj khov. Lawv yuav tsum tau ua qhov tseeb installation - tag nrho cov kev khiav hauj lwm yog tib yam li nyob rau hauv cov ntaub ntawv ntawm ib tug qauv. Tsis tas li ntawd, tom qab siv cov ntsiab lus, cov iav sib cais tau muab tso rau hauv qhov chaw. Kev txhim kho nws tsis txawv ntawm tus qauv. Tom qab ntawd koj tuaj yeem muab txoj siv sia rau ntawm qhov uas tau nruab tshiab.

Nws yog ib qho tseem ceeb uas yuav tsum tau kuaj xyuas ntau zaus tias cov ntawv sau sib haum. Rau kev ua tau zoo tshaj plaws, nws yog qhov yuav tsum tau uavalve qhib tswj. Qhov ntsuas no yog nruj me ntsis txwv thiab teem rau theem tsim ntawm ib tug tshwj xeeb camshaft. Yog tias cov li qub tau qhib rau tus nqi ntau dua li cov ntaub ntawv hla tebchaws, ces cov bolts ntawm lub iav, uas nyob sab nraud, yog loosened. Tom qab ntawd tig cov khoom faib tawm mus rau sab nraud ib nrab ntawm kev sib cais kom cov parameter tuaj yeem hloov kho tau yooj yim.

Thaum nws muaj peev xwm los teeb tsa xoom txoj hauj lwm ntawm lub camshaft, nws yog ib qho tsim nyog los ua qhov kev hloov kho ntawm cov theem. Yog hais tias lub sab sauv ncej yog tig nyob rau hauv cov kev taw qhia ntawm kev sib hloov ntawm lub qis (crankshaft), yog li ua rau thrust. Torque yuav muaj nyob rau hauv nruab nrab thiab qis. Yog hais tias qhov sib cais ntawm lub camshaft (VAZ-2108 los yog lwm lub tsheb qauv, tsis yog li ntawd tseem ceeb) thiab ncej nws tus kheej yog tig nyob rau hauv cov kev taw qhia opposite rau kev sib hloov ntawm lub crankshaft, ces lub hwj chim yuav nce.

Thaum ua cov txheej txheem kho no, nws yog ib qho tseem ceeb kom tsis txhob mus ntau tshaj ib nrab ntawm tus hniav ntawm lub rubey los ntawm qhov pib. Yog tias lub iav hloov kho rau cov carburetor, tom qab txhua qhov kev tswj hwm ntawm tus ncej, yuav tsum tau kho lub kaum sab xis ntawm qhov hluav taws xob. Txwv tsis pub, yuav muaj kev cuam tshuam hauv qhov system.

16-valve engines VAZ-2110-2112

Yog tias cov iav sib cais tau hloov kho rau cov motors no, ces nws tseem pom zoo kom nruab cov camshafts nrog nws. Koj yuav tsum tau coj los ntawm cov cim ua hauv lub hoobkas. Lawv kwv yees kho qhov kaw / qhib ntawm li qub. Tom qab ntawd qhov chaw ntawm qhov chaw tuag saum toj kawg nkaus raug coj muspiston ntawm thawj thiab thib ob lub tog raj kheej. Tsis tas li ntawd, ib txoj siv tau ua tib zoo muab tso rau ntawm lub iav.

Tom qab ntawd, koj yuav tsum teeb tsa cov ntsuas. Lawv yuav pab txiav txim seb cov li qub yuav txav mus li cas. Nws yog ib qho tsim nyog yuav tau nrhiav ib txoj hauj lwm uas cov txheej txheem ntawm lub tog raj kheej plaub yuav raug kaw tag nrho. Tom ntej no, nrog kev pab los ntawm ib lub iav thiab qhov taw qhia, qhov kaw tau raug kho. Tom qab ntawd koj tuaj yeem ua kom nruj cov bolts, sib sau ua ke lub zog thiab ua qhov kev sim tsav.

YClassic VAZ

Rau classic yim-valve xyaw, lub iav tau teeb tsa rau cov cim Hoobkas. Tom ntej no, kho lub valve kaw. Thawj thiab thib plaub pistons yog teem rau TDC. Cov taw qhia taw yuav tsum tau so tawm tsam tus rocker.

Ib qho los ntawm ib qho teeb tsa thaum lub valve raug kaw ntawm thawj lub tog raj kheej. Tom qab ntawd, qhov tseeb txoj haujlwm ntawm TDC ntawm lub iav tuned tau teeb tsa. Tsis txhob hnov qab txog cov iav piv ntawm cov rockers thiab qhov taw tes qhov taw qhia tau teeb tsa. Tom ntej no, lub iav yog tsau, sib sau ua ke thiab lub cav pib.

Zoo kawg

Yog li, nrog kev pab ntawm ib lub iav, koj tuaj yeem txhim kho qhov pib tsis zoo ntawm VAZ xyaw. Qhov no yog qhov nrov nrov tuning ntawm domestic cav.
