Dab tsi yog Hom Spark Plugs?

Raws li tus nqi calorific, muaj hom txias thiab kub hom; Raws li cov khoom siv electrode, muaj nickel alloy, silver alloy thiab platinum alloy; Yog tias nws yog tus kws tshaj lij, cov khoom siv hluav taws xob feem ntau yog raws li hauv qab no:
1. Quasi-type spark plug:Nws lub tsho insulator yog me ntsis shrunk rau hauv lub ntsej muag kawg ntawm lub tsev, thiab sab electrode yog sab nraum lub ntsej muag kawg ntawm lub tsev, uas yog hom siv dav tshaj plaws.
2. Spark plug nrog protruding ntug:Lub tsho insulator ntev dua thiab protrudes dhau lub ntsej muag kawg ntawm lub tsev. Nws muaj qhov zoo ntawm kev nqus cua kub loj thiab muaj peev xwm tiv thaiv fouling zoo, thiab tuaj yeem ua kom txias ncaj qha los ntawm kev nqus cua kom txo qhov kub, yog li nws tsis yooj yim los ua kom kub kub, yog li thermal adaptation ntau yam.
3. Electrode hom spark plug:Nws cov electrode yog nyias nyias, tus yam ntxwv los ntawm muaj zog spark thiab muaj peev xwm ignition zoo. Nws tuaj yeem ua kom ntseeg tau tias lub cav tuaj yeem pib sai thiab ntseeg tau thaum lub caij txias txias, nrog rau ntau yam thermal thiab tuaj yeem ua tau raws li ntau lub hom phiaj.
4. Seat hom spark plug:Nws lub plhaub thiab cov ntsia hlau-hauv xov yog tsim rau hauv lub khob hliav qab, yog li nws tuaj yeem tswj tau zoo sealing yam tsis muaj gasket, yog li txo qhov ntim ntawm lub txim hluav taws xob, uas muaj txiaj ntsig zoo rau lub cav tsim.
5. Ncej hom spark plug:Sab electrode feem ntau yog ob lossis ntau dua. Qhov kom zoo dua yog txhim khu kev qha ignition, thiab qhov sib txawv tsis tas yuav tsum tau kho ntau zaus. Yog li ntawd, nws yog feem ntau siv nyob rau hauv ib co roj av cav qhov twg cov electrode yog ib qho yooj yim mus ablate thiab lub txim plug qhov sib txawv tsis tuaj yeem kho ntau zaus.
6. Nto spark plug:Ntawd yog, qhov sib txawv ntawm qhov chaw. Nws yog hom txias tshaj plaws ntawm lub txim hluav taws xob. Qhov sib txawv ntawm nws lub hauv paus electrode thiab lub ntsej muag kawg ntawm lub plhaub yog concentric.
7. Txheem thiab protruding spark plugs
Tus qauv txim hluav taws xob yog ib qho hluav taws xob hluav taws xob ib sab uas nws lub tsho insulator kawg yog me ntsis qis dua qhov xov kawg ntawm lub tsev. Nws siv cov txheej txheem ignition kawg uas yog feem ntau siv nyob rau hauv sab-mounted valve xyaw. Txhawm rau kom paub qhov txawv ntawm qhov tom qab "hom tseem ceeb", cov qauv no hu ua "tus qauv".
Protrusive spark plugs yog Ameslikas tsim rau overhead valve engines. Nws daim tiab insulator protrudes los ntawm threaded kawg lub ntsej muag ntawm lub plhaub thiab txuas mus rau hauv lub combustion chamber. Nws absorbs cua sov ntau dua nyob rau hauv qhov sib xyaw combustion, thiab muaj qhov kub thiab txias ua hauj lwm ntawm so ceev kom tsis txhob muaj kab mob; Nyob rau hauv kev kub ceev, vim hais tias lub valve yog overhead, lub inhaled cua ntws aims ntawm lub insulator tiab thiab txias nws, yog li ntawd lub siab tshaj plaws kub yog tsis nce ntau, yog li ntawd lub thermal range yog loj. Lub qhov hluav taws xob tawm ntawm lub qhov hluav taws xob tsis haum rau lub tshuab hluav taws xob sab-mounted valve vim tias muaj ntau qhov khoov hauv qhov nkag thiab cov cua txias me ntsis ntawm cov cua ntws ntawm lub tsho insulator.
8. Ib leeg-ncej thiab ntau-ncej taub hau ntsaws
Cov tsoos ib leeg-ncej lub taub hau muaj qhov pom tseeb tsis xws luag, uas yog, sab electrode npog qhov chaw electrode. Thaum cov hluav taws xob muaj hluav taws xob ntau tshwm sim ntawm ob tus ncej, qhov sib xyaw ntawm qhov sib txawv ntawm qhov sib txawv yuav nqus tau lub txim hluav taws xob thiab raug qhib los ntawm ionization los ua "qhov hluav taws kub". Qhov chaw uas cov tub ntxhais hluav taws tsim yog feem ntau nyob ze rau ntawm sab electrode, thiab cov cua sov yuav nqus los ntawm sab electrode ntau dua, uas yog, "cov nplaim hluav taws kub hnyiab" ntawm cov electrode, uas txo cov txim hluav taws xob thiab txo qhov hluav taws kub. dhia kev ua haujlwm.
Yog li, nyob rau xyoo 1920, peb-ncej qhov hluav taws xob tau tshwm sim. Piv nrog rau ib sab electrode, qhov sib txawv ntawm ntau sab electrodes yog tsim los ntawm ntu ntawm ntau sab electrodes (punched rau hauv ib lub voj voog) thiab cylindrical nto ntawm lub hauv paus electrode. Qhov no sab-mounted sparks tshem tawm qhov tsis xws luag uas sab electrode npog lub hauv paus electrode, thiab ua rau kom "accessibility" ntawm lub txim. Lub txim hluav taws xob yog qhov loj, thiab nws yooj yim rau nkag mus rau hauv lub tog raj kheej, uas yuav pab txhim kho qhov sib xyaw ntawm cov khoom sib xyaw thiab txo cov pa tawm. Vim hais tias ntau sab ncej muab ntau yam ignition channel, kev pab cuam lub neej yog txuas ntxiv thiab lub ignition kev ntseeg tau zoo dua. Nws yuav tsum tau taw qhia rau ntawm no tias qhov tam sim ntawm kev tso tawm tuaj yeem tsuas yog flashover ntawm ib lub channel, thiab nws tsis tuaj yeem flashover ntawm ntau tus ncej tib lub sijhawm. Cov txheej txheem tso tawm ntawm kev yees duab nrawm ua pov thawj qhov no.
Cov tsiaj ntawv tom qab (cov ntawv tom qab tus lej tus nqi calorific) D, J thiab Q hauv cov qauv hluav taws xob hauv tsev qhia txog ob sab ncej, peb sab ncej thiab plaub sab ncej raws li.
9. Nickel puag alloy thiab tooj liab tub ntxhais electrode spark plug
Qhov tseem ceeb tshaj plaws uas yuav tsum tau rau cov electrode txuas mus rau hauv lub combustion chamber yog ablation tsis kam (hluav taws xob thiab tshuaj corrosion) thiab zoo thermal conductivity. Nrog rau txoj kev loj hlob ntawm cov ntaub ntawv science thiab technology, cov ntaub ntawv electrode tau ntsib cov evolution ntawm hlau, npib tsib xee, npib tsib xee-raws li alloys, npib tsib xee tooj liab composites thiab precious hlau. Nickel puag alloys yog cov feem ntau siv niaj hnub no. Feem ntau, cov thermal conductivity ntawm cov hlau ntshiab yog zoo dua li ntawm cov hlau, tab sis cov tshuaj tiv thaiv corrosion ntawm cov hlau ntshiab (xws li npib tsib xee) rau combustion gas thiab cov khoom deposits tsim yog rhiab dua li cov hlau. Yog li ntawd, cov khoom siv electrode yog ua los ntawm npib tsib xee puag thiab ntxiv nrog cov ntsiab lus xws li chromium, manganese thiab silicon. Chromium txhim kho kev tiv thaiv hluav taws xob corrosion, thaum manganese thiab silicon txhim kho cov tshuaj tiv thaiv corrosion, tshwj xeeb tshaj yog tiv thaiv sulfur oxide nrog kev puas tsuaj loj.
10. Ordinary thiab tsis kam spark plugs
Raws li lub tshuab hluav taws xob tawm hluav taws xob, lub txim hluav taws xob yog qhov sib txuas txuas txuas hluav taws xob hluav taws xob hluav taws xob cuam tshuam cuam tshuam. Txhawm rau txhawm rau cuam tshuam cov hluav taws xob muaj zog ntawm hluav taws xob hluav taws xob hauv xov tooj cua hluav taws xob los ntawm hluav taws xob dhia, tiv thaiv kev sib txuas lus hauv xov tooj cua thiab tiv thaiv kev ua haujlwm tsis zoo ntawm cov khoom siv hluav taws xob hauv lub nkoj, cov teb chaws thoob plaws ntiaj teb tau nce kev txhim kho ntawm cov hluav taws xob tiv thaiv txij li xyoo 1960. Tuam Tshoj kuj tau tshaj tawm cov txheej txheem tseem ceeb hauv lub tebchaws rau kev sib raug zoo ntawm electromagnetic, uas nruj me ntsis txwv cov xov tooj cua cuam tshuam cov yam ntxwv ntawm lub tsheb uas tau tsav los ntawm lub tshuab hluav taws xob hluav taws xob, yog li qhov kev thov rau cov hluav taws xob tiv thaiv hluav taws xob kuj tau nce ntxiv. Tsis muaj qhov sib txawv loj ntawm qhov kev tiv thaiv hom hluav taws xob thiab cov hom zoo tib yam hauv cov qauv, tsuas yog hloov tus neeg xyuas pib sealant hauv lub cev rwb thaiv tsev mus rau qhov tsis kam sealant.
