Trambler: ntaus ntawv thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm
Ib tug distributor, los yog lub ignition distributor breaker, yog ib qho tseem ceeb ntawm cov roj av combustion engine. Nws yog ua tsaug rau cov distributor uas ib tug hluav taws xob impulse yog siv rau txhua lub txim plugs, uas ua rau nws tawm thiab ignite cov roj-cua sib tov nyob rau hauv lub combustion chamber ntawm txhua lub pistons.
Tus qauv tsim ntawm cov cuab yeej no tseem tsis tau hloov pauv txij li nws qhov kev tsim tawm hauv xyoo 1912 los ntawm American inventor thiab ua lag luam ua tau zoo Charles Kettering. Tshwj xeeb, Kettering yog tus tsim ntawm lub tuam txhab paub zoo Delco, nws muaj 186 patents ntsig txog hluav taws xob tiv thaiv hluav taws xob.
Cia peb sim nkag siab txog cov cuab yeej thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub ignition distributor breaker.
Ntaus ntawv
Peb yuav tsis piav qhia meej txhua lub tshuab ntxhua khaub ncaws thiab lub caij nplooj ntoos hlav, txij li muaj ib tsab xov xwm ntawm peb lub vev xaib Vodi.su uas tau tshaj tawm cov cuab yeej siv tau yooj yim.
Cov ntsiab lus tseem ceeb yog:
- distributor tsav (rotor) - ib tug splined cov menyuam uas koom nrog lub camshaft iav los yog ib tug tshwj xeeb promshaft (nyob ntawm seb lub cav tsim);
- ignition kauj nrog ob chav winding;
- interrupter - nyob rau hauv nws muaj ib tug cam clutch, ib pab pawg neeg ntawm kev sib cuag, ib tug centrifugal clutch;
- distributor - ib tug slider (nws yog txuas rau lub clutch tsav ncej thiab tig nrog nws), ib tug distributor cover (high-voltage xov hlau tawm ntawm nws mus rau txhua tus tswm ciab).
Tsis tas li ntawd ib qho tseem ceeb ntawm lub distributor yog lub tshuab nqus tsev ignition lub sij hawm regulator. Lub Circuit Court muaj xws li ib tug capacitor, lub luag hauj lwm tseem ceeb ntawm cov uas yog los ntawm ib feem ntawm tus nqi, yog li tiv thaiv cov pab pawg neeg ntawm kev sib cuag los ntawm sai melting nyob rau hauv lub siab ntawm high voltage.
Tsis tas li ntawd, nyob ntawm seb hom distributor, nyob rau hauv qis qis, structurally txuas nrog tus tsav cov menyuam, ib qho octane corrector yog ntsia, uas kho qhov kev sib hloov ceev rau ib yam ntawm cov roj av - octane tooj. Nyob rau hauv cov laus versions, nws yuav tsum tau kho manually. Tus lej octane yog dab tsi, peb kuj tau hais rau ntawm peb lub vev xaib Vodi.su.
Yuav ua li cas nws ua hauj lwm
Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog qhov yooj yim heev.
Thaum koj tig tus yuam sij hauv qhov hluav taws xob, hluav taws xob hluav taws xob tau ua tiav thiab qhov hluav taws xob los ntawm lub roj teeb nkag mus rau lub tshuab hluav taws xob. Lub oob khab bendix koom nrog lub crankshaft flywheel crown, ntsig txog, lub zog ntawm lub crankshaft yog kis mus rau lub iav tsav ntawm lub ignition distributor ncej.
Nyob rau hauv cov ntaub ntawv no, ib tug Circuit Court kaw nyob rau hauv thawj winding ntawm lub kauj thiab ib tug tsawg-voltage tam sim no tshwm sim. Lub breaker hu qhib thiab high voltage tam sim no accumulates nyob rau hauv lub thib ob Circuit Court ntawm lub kauj. Tom qab ntawd qhov tam sim no yog nkag mus rau lub npog ntawm tus neeg xa khoom - hauv nws qhov qis dua muaj graphite tiv tauj - thee lossis txhuam.
Tus khiav yog tas li nyob rau hauv kev sib cuag nrog lub hauv paus electrode thiab, raws li nws rotates, kis ib feem ntawm lub voltage hloov mus rau txhua yam ntawm cov kev sib cuag nrog ib tug tshwj xeeb txim plug. Ntawd yog, qhov voltage induced nyob rau hauv ignition coil yog sib npaug faib ntawm tag nrho plaub tswm ciab.
Lub tshuab nqus tsev regulator yog txuas los ntawm ib lub raj mus rau lub intake manifold - throttle qhov chaw. Raws li, nws reacts rau ib tug kev hloov nyob rau hauv qhov kev siv ntawm cov huab cua sib tov khoom rau lub cav thiab hloov lub ignition sij hawm. Qhov no yog qhov tsim nyog kom lub txim hluav taws xob nkag mus rau lub tog raj kheej tsis yog lub sijhawm thaum lub piston nyob rau saum toj kawg nkaus, tab sis ua ntej me ntsis. Detonation yuav tshwm sim raws nraim thaum lub sij hawm cov roj-cua sib tov yog txhaj rau hauv lub combustion chamber, thiab nws lub zog yuav thawb lub piston down.
Lub centrifugal regulator, uas nyob rau hauv lub tsev, teb rau cov kev hloov nyob rau hauv lub ceev ntawm kev sib hloov ntawm lub crankshaft. Nws txoj hauj lwm kuj yog los hloov lub sij hawm ignition kom cov roj siv tau zoo li sai tau.
Nws yuav tsum tau muab sau tseg tias hom distributor nrog ib tug neeg kho tshuab distributor yog ntsia mas nyob rau hauv lub tsheb nrog carburetor-hom cav. Nws yog qhov tseeb tias yog tias muaj cov khoom sib hloov, lawv hnav tawm. Hauv cov tshuab txhaj tshuaj lossis ntau lub tshuab carburetor niaj hnub no, tsis yog siv lub tshuab ua haujlwm, Hall sensor yog siv, ua tsaug rau qhov kev faib tawm los ntawm kev hloov qhov sib nqus ntawm qhov sib nqus (saib Hall effect). Qhov system no ua haujlwm zoo dua thiab siv qhov chaw tsawg dua hauv qab lub hood.
Yog tias peb tham txog cov tsheb niaj hnub tshaj plaws nrog cov tshuaj txhaj tshuaj thiab cov tshuaj txhaj tshuaj, ces siv lub tshuab hluav taws xob hluav taws xob nyob rau ntawd, nws tseem hu ua contactless. Cov kev hloov ntawm lub cav ua haujlwm hom yog saib xyuas los ntawm ntau yam sensors - oxygen, crankshaft - los ntawm cov teeb liab raug xa mus rau chav tswj hluav taws xob, thiab cov lus txib tau xa los ntawm nws mus rau qhov hluav taws xob hloov hluav taws xob.
