spark plug hnav
Cov txheej txheem coj ntawm lub txim hluav taws xob nyob ntawm ntau yam, tab sis txawm tias nyob rau hauv lub tshuab ua haujlwm zoo kawg nkaus, lawv lub neej muaj kev txwv thiab cov cim ntawm kev hnav tsis tas yuav pom.
Cov laj thawj rau qhov tsis zoo zuj zus ntawm cov khoom ntawm lub txim hluav taws xob yog qhov tshwm sim uas nrog rau lawv txoj haujlwm. Kev hnav ntawm cov electrodes yog vim hluav taws xob yaig ntawm cov chaw ua haujlwm los ntawm kev dhia cyclic ntawm lub txim ntawm lawv. Tsis zoo 
Cov nyhuv ntawm electroerosion yog maj mam nce qhov sib txawv ntawm cov electrodes, uas ua rau muaj kev nce hauv qhov hluav taws xob tsim nyog los ua kom muaj hluav taws xob tawm hauv daim ntawv ntawm lub txim. Vim muaj kev xav tau ntawm lub zog loj zuj zus, qhov hluav taws xob hluav taws xob yog tsim los kom muaj qee yam ntawm cov hluav taws xob siab tsim, uas lav lub txim hluav taws xob zoo hauv txhua qhov kev ua haujlwm. Lwm qhov tshwm sim uas cuam tshuam rau qhov hnav ntawm lub qhov hluav taws xob hluav taws xob yog corrosion vim qhov kev txiav txim ntawm cov roj kub kub hauv lub combustion chamber.
Ceramic insulators ntawm spark plugs kuj maj mam poob lawv cov khoom. Qhov no yog qhov tshwm sim ntawm qhov ntev raug rau qhov kub thiab txias uas ua rau lub cev ua haujlwm ntawm lub tshuab hluav taws xob sab hauv. Nws yog tsis yooj yim sua kom pom cov kev hloov nyob rau hauv cov qauv ntawm insulators, tsuas yog rau pom tseeb tawg thiab poob. Kev tawg thiab kab noj hniav feem ntau yog tshwm sim los ntawm kev cuam tshuam los yog kev siv tsis raug.
Txoj kev hnav khaub ncaws hnyav ua rau nws tsim nyog yuav tsum tau hloov lub sijhawm hloov lub txim hluav taws xob raws li cov chaw tsim khoom cov lus pom zoo, txawm tias qhov tshwm sim ntawm cov insulator thiab electrodes tsis qhia txog kev puas tsuaj ntawm cov khoom.
