Central Electrode ntawm Spark Plug

Central Electrode ntawm Spark Plug yog ib qho ntawm nws cov tseem ceeb, lub luag haujlwm rau tsim hluav taws xob hluav taws xob kom loj. Nws cov qauv, cov khoom thiab cov qauv qhia ncaj qha cuam tshuam rau kev tiv thaiv kev tiv thaiv, kev siv taus thiab kev tsim tawm. Cov hauv qab no yog cov ncauj lus kom ntxaws kev tshuaj ntsuam ntawm lub chaw nruab nrab ntawm lub txim taws plug:

1. Txoj haujlwm ntawm Central Electrode ntawm Spark Plug

Tsim kom muaj hluav taws xob hluav taws xob: High-voltage tam sim no jumps los ntawm nruab nrab electrode rau lub hauv paus nruab nrab rau electrode (sab electrode), sib sau lub zog arc uas taws teeb roj.

Kev kub siab thiab kev kub siab kuj: tuaj yeem tiv thaiv cov huab ib puag ncig hauv kev sib txuas ua ke (nrog rau kev kub ntxhov ntau dua 2000℃thiab ntsuas tshaj 50BAR).

Thermal Tshuav: Ib nrab ntawm tshav kub yog pauv mus rau lub spark plug tsev nyob los ntawm cov khoom siv electrode los tiv thaiv cov khoom siv hluav taws xob kom tiv thaiv kev ua kom dhau los yog cov zaub mov ua haujlwm.

2. Central Electrode ntawm Spark Plug Cov Ntsiab Lus thiab Tsim

(1) hla

Cov Qauv Electrode: txoj kab uas hla ntawm Tsoos Nickel Electrodes yog kwv yees li 2.5mm, nrog tus nqi luv tab sis tus nqi qis.

Cov tshuaj hluav taws xob zoo: iridium lossis platinum cov ntaub ntawv tuaj yeem yog li 0.4-0.6mm, txo qhov kev tiv thaiv hluav taws xob yuav tsum muaj thiab txhim kho cov nplaim hluav taws sib luag.

(2) duab

Conical cov lus qhia: txo kev tawm tsam corona (xws li NGK's Laser Iridium Series).

Ntau-faceted tsim: nce ntug kev tawm tsam cov ntsiab lus kom txuas txoj kev pabcuam ntev (xws li Bosch cov khoom siv me me).

(3) kev tawm tsam

Protruding electrode: nthuav dav ntxaum rau hauv kev sib txuas ntawm chav ua ke los txhim kho cov roj kev sib txuas ua haujlwm (xws li cov qauv siv tshuab ua haujlwm siab).

Indented Electrode: txo kev tawm tsam kev phom sij (tsim nyog rau kev txhawb nqa lub zog).

3. Cov khoom siv classification thiab cov yam ntxwv

Cov khoom siv cov yam ntxwv ib txwm muaj cov teeb meem

Nickel alloy yog yig thiab ruaj, tab sis nws corrosion tsis kam yog qhov nruab nrab thiab nws yog ib txwm ua rau oxidation. Nws yog qhov haum rau cov laus carburetor engines uas tau mus ncig 20,000 txog 30,000 kilometers

Platinum tau muaj zog kub-kub tsis kam thiab corrosion tsis kam. Qhov taw qhia-welded platinum daim ntawv tuaj yeem mus txog 60,000 txog 80,000 km rau cov tsheb thauj khoom niaj hnub (xws li Denso PK series).

Iridium muaj ib qho siab heev melting point (2450 degree), nws muaj qhov zoo tshaj plaws tsis txaus ntseeg. 80}}

Nyiaj muaj qhov zoo tshaj thermal conductivity, tab sis nws yog nquag hnav thiab kua muag rau kev sib tw tsheb lossis qib siab-ceev cov cav uas tau mus 10,000 txog 20,000 mais

Kev lag luam turbocharged nrog ntau ntawm 30,000 rau 50,000 rau 50,000 rau 50,000 rau ntawm Bimetallic Central Core (rau cov nickel sab nraud) thiab lub zog sab nraud (rau lub zog sab nraud (rau lub zog

4. Ua tsis tiav cov qauv thiab kev kuaj mob

Cov ntsiab lus: Lub ntsiab lus sib npaug lossis cov pits tshwm sim (sib xyaw yog ib yam nkaus dhau lawm / tseem ntxov dhau lawm).

Cov pa roj carbon tso nyiaj: cov electrode nyob rau hauv ib tug dub txheej txheej (vim tsav tsheb cav tsis huv lossis ntev-tsheb ceev).

Ceramic lub cev tawg pleb: Ua rau cov tshuaj lom neeg mob hnyav thiab hluav taws (thermal poob siab los yog ncu kom nruj heev).

Clearance nthuav dav: yog tias nws tshaj 0.1mm ib 10,000 mais, yog tias tus qauv txheem kev tshem tawm ua tau los ntawm 0.8mm txog 1.2mm, nws yuav tsum tau hloov).

5. Kev hloov thev naus laus zis thiab kev tsim kho tshiab

Multi Electrode Tsim: xws li Bosch-electrode spark plugs, uas disperse ploj los ntawm ntau cov av hluav taws xob.

Cov thev naus laus zis tawm: Lub arc nto yog tsim tawm nruab nrab ntawm nruab nrab ntawm Central thiab cov ntsiab lus hauv av hluav taws xob (xws li qee qhov ntsaws ntsaws rau hauv ANOERO cav).

Uh-hlawv MAP electrode: lub Groove nta tau ua kom nrawm dua qhov kev tsim cov nplaim hluavti (xws li tus yeej powerX series).
