Kev teeb tsa thiab kev saib xyuas ntawm lub throttle valve yuav tsum tau them sai sai rau cov khoom hauv qab no

Lub valve feem ntau yuav tsum tau ua haujlwm, yog li nws yuav tsum tau nruab rau hauv txoj haujlwm uas yooj yim thiab yooj yim rau kev khiav lag luam.
Thaum txhim kho, ua tib zoo saib xyuas cov kev taw qhia ntawm qhov nruab nrab raws li cov kev taw qhia ntawm xub cim ntawm lub valve lub cev.
1. Cov peev txheej ntawm lub cev lub cev tso tawm yog qhov nyuaj dua, tab sis lawv tuaj yeem muab faib ua pawg hauv qab no:
1. Mechanical impurities nyob rau hauv cov roj los yog colloid, asphalt, carbon residue thiab lwm yam av vim oxidation yog accumulated nyob rau hauv lub throttling sib txawv.
2. Vim yog kev laus los yog extrusion ntawm cov roj, them polarized molecules yog tsim, thiab muaj peev xwm sib txawv ntawm cov hlau nto ntawm lub throttling gap, yog li cov polarized molecules yog adsorbed rau saum npoo ntawm qhov sib txawv, tsim ib tug ruaj khov ciam teb. Cov txheej txheem adsorption, thiab cov tuab ntawm cov txheej adsorption feem ntau yog 5 ~ 8 microns, uas cuam tshuam qhov loj ntawm qhov sib txawv. Thaum cov saum toj no accumululations thiab adsorbates loj hlob mus rau ib tug tej thickness, lawv yuav raug ntxuav tawm los ntawm cov kua ntws, thiab ces reattached rau lub valve chaw nres nkoj. Rov ua li no, lub pulsation ntawm cov ntws yog tsim.
3. Thaum lub siab sib txawv ntawm qhov chaw nres nkoj valve yog qhov loj, vim qhov kub ntawm qhov chaw nres nkoj valve, qhov degree ntawm extrusion ntawm cov kua yog txhim khu kev qha, thiab cov hlau nto kuj tseem muaj kev cuam tshuam rau kev sib txhuam los ua qhov sib txawv. Yog li ntawd, thaum lub siab sib txawv loj, qhov txhaws yuav tshwm sim.
4. PCV tso pa tawm qhov chaw: cov khoom sib tov sib xyaw hauv cov combustion chamber nkag mus rau hauv lub crankcase los ntawm qhov sib txawv piston, thiab yog tov nrog cov roj cav vapor los ua cov roj sib xyaw. Txhawm rau kom tsis txhob diluting thiab paug cov roj, qhov sib tov yog rub mus rau hauv qhov nqus tau los ntawm qhov zoo crankcase qhov cua tshuab (PCV) rau kev sib txuas ntxiv. Tom qab ib feem ntawm cov pa tso pa nkag mus rau hauv qhov chaw nres nkoj, nws yuav condense los tsim cov kua theem vim qhov kub thiab txias, thiab "cov khoom tsis ruaj khov" hauv nws yuav oxidize thiab condense ntawm qhov kub thiab txias, thiab tsim cov roj rau ntawm qhov chaw. throttle valve thiab ua raws li nws.
5. Nyob rau hauv-tob lubricating roj rau turbocharged compressors: Rau turbocharged xyaw, cov pa roj pa tsav txoj kev yog feem ntau saws, uas yog, lub high-pressure tso pa roj generated los ntawm lub tso pa tawm yog siv los tsav lub turbine, thiab cov compressor hniav nyob rau hauv lub siab. Qhov kev nkag mus yog tsav los ntawm coaxial, tsim kom muaj cua nkag chaw nres nkoj cua siab boost. Txawm li cas los xij, nyob rau hauv lub sij hawm ntev thiab hnyav ua hauj lwm, coaxial bearings yog nquag nkag mus thiab volatilization ntawm lubricating roj, thiab cov efficiency ntawm inflation yog ob npaug, uas yog ntau dua yuav hnyav hnyav thiab adhesion ntawm throttle lub cev deposits.
6. Roj vapor tso tawm los ntawm cov pa roj carbon canister: Ntawm cov roj vapor absorbed los ntawm carbon canister ntawm lub cav, cyclopentadiene yog ib qho yooj yim los tsim throttle valve deposits, thiab nws yuav oxidized thiab condensed rau daim ntawv colloidal roj nyob rau hauv tas li ntawd kub kub.

Throttle valve tu thiab tu
Thaum lub throttle valve (npauj npaim valve) raug thaiv los ntawm deposits, lub throttle qhib tus nqi yuav muaj teeb meem, thiab lub cav tsis tuaj yeem tswj nws qhov qhib ruaj khov thiab raug. Yog tias tus nqi qhib qis dhau lawm, nws yuav ua rau muaj teeb meem hauv kev pib, tsis ruaj khov idling ceev lossis txawv txav flameout; Thaum lub cav nrawm thiab nrawm, lub throttle valve tsis tuaj yeem teb tau raws sijhawm, uas yuav ua rau kom nrawm nrawm lossis nrawm nrawm.
