Tsheb Spark Plug Maintenance Knowledge

(1) Lub txim hluav taws xob yog ablated hnyav heev. Sab saum toj ntawm lub txim hluav taws xob yog caws pliav lossis puas, lossis cov electrode yog yaj lossis ablated.
(1) Lub electrode melts thiab lub insulator tig dawb. Qhia tias qhov kub thiab txias hauv chav combustion siab dhau lawm. Qhov no tej zaum yuav tshwm sim los ntawm ntau cov pa roj carbon deposits nyob rau hauv lub combustion chamber, ua rau lub valve clearance me me heev, ua rau lub tso valve overheat los yog lub txias ntaus ntawv ua hauj lwm tsis zoo. Nws kuj tseem yuav yog tias lub txim hluav taws xob tsis nruj rau qhov teev torque, thiab lwm yam.
(2) Cov electrode ua puag ncig thiab cov insulator muaj caws pliav. Qhia tias lub cav ua ntej igniting, tejzaum nws vim lub sij hawm ignition yog ntxov dhau los yog siv. Cov roj av qib qis dhau lawm, tus nqi calorific ntawm lub txim hluav taws xob siab dhau lawm, thiab lwm yam.;
(3) Sab saum toj ntawm lub insulator yog tawg. Detonation combustion yog lub ntsiab ua rau insulator rupture. Lub sij hawm ignition yog ntxov dhau thiab cov roj av qib qis. , qhov kub ntawm lub combustion chamber yog siab dhau lawm, uas yuav ua rau lub cav khob thiab combustion.
(4) Muaj kab txaij grey thiab dub nyob rau saum lub insulator. Cov kab txaij no qhia tau hais tias lub txim hluav taws xob tau tawg thiab yuav tsum tau hloov nrog ib qho tshiab.
(2) Lub tshuab hluav taws xob muaj qhov tso nyiaj. Muaj qee zaum cov khoom daig ntawm qhov kawg ntawm lub qhov hluav taws xob insulator thiab cov electrode.
(1) Oily deposits. Oily deposits ntawm lub txim taws qhia tias cov roj lubricating tau nkag mus rau hauv lub combustion chamber. Yog tias nws tsuas yog ob peb lub taub hau, lub valve qia roj foob yuav puas. Yog tias lub txim hluav taws xob ntawm txhua lub tog raj kheej tau daig nrog cov kev tso nyiaj zoo li no, nws qhia tias cov roj tawm hauv lub tog raj kheej, thiab lub tshuab lim cua thiab cua tshuab yuav tsum tau kuaj xyuas seb lawv puas raug thaiv.
(2) Cov xim dub. Muaj cov deposits dub ntawm cov electrodes thiab sab hauv ntawm lub qhov hluav taws xob, qhia tias qhov sib tov yog nplua nuj heev. Ua kom lub cav ceev thiab txuas ntxiv mus rau txhua feeb tuaj yeem hlawv tawm ntawm txheej txheej ntawm cov pob zeb dub sab laug ntawm cov electrodes.
