Iyiphi indlela engcono kakhulu yokushintsha ama-spark plug: enjini ebandayo noma eshisayo
Okuqukethwe
Ama-electrode esiliva abonakala ngokusebenza okuphezulu kwe-thermal. Ngenxa yalokhu, zihlala isikhathi eside izikhathi ezi-2 kunezinto ezijwayelekile zokuthungela. Umkhawulo wabo wokuphepha wanele amakhilomitha ayizinkulungwane ezingu-30-40 noma iminyaka engu-2 yokusebenza.
Uma ungazi ukuthi uzowashintsha nini ama-spark plug enjini ebandayo noma eshisayo, kulula ukulimaza izintambo. Ngokuzayo, umnikazi wemoto angase abe nobunzima bokukhipha ingxenye egugile.
Ukushintsha ama-spark plug: shintsha ama-spark plug enjini ebandayo noma eshisayo
Imibono engqubuzanayo ibhaliwe mayelana nendlela engcono kakhulu yokulungisa. Abanikazi abaningi bezimoto kanye noomakhenikha bezimoto bathi ukususwa nokufakwa kwezinto ezisetshenziswayo kufanele kwenziwe ngemoto epholile ukuze kungashiswa futhi kunqamuke intambo.
Esikhungweni sesevisi, amakhandlela ngokuvamile ashintshwa enjini efudumele. Laba bashayeli bathi izingcweti zijahile ukuyokwenza lokho njengoba bengenabalandeli. Omakhenikha bezimoto bachaza ukuthi kulula ukususa ingxenye ebhajiwe emotweni efudunyezwe kancane. Futhi uma ukulungiswa kwenziwa emazingeni okushisa aphezulu kakhulu noma aphansi, kuzoba yinkinga ukususa ingxenye. Futhi kwandisa ingozi yokulimala kwekepisi yocingo lapho uyinqamula ekhandlelani.
Uyini umehluko
Eqinisweni, ungashintsha izinto ezisetshenziswayo zesistimu yokuthungela enjini efudumele nebandayo, kodwa ezimweni ezithile.
Ungawashintsha kanjani amakhandlela ngezandla zakho
Ukuze uqonde ukuthi ungayenza kanjani le nqubo ngendlela efanele, kufanele ukhumbule imithetho ethile ye-physics. Kunomqondo we-coefficient yokwanda kwe-thermal. Ibonisa ukuthi into izoba nkulu kangakanani uma iqhathaniswa nosayizi wayo uma ishiswa ngedigri engu-1.
Manje sidinga ukucabangela izakhiwo zezinto zomshini wokuthungela ekushiseni kwe-20-100 ° C:
- Ikhandlela lensimbi elijwayelekile line-coefficient yomugqa wokunweba okushisayo okungu-1,2 mm/(10m*10K).
- Le parameter yentambo yomthombo we-aluminium ingu-2,4 mm / (10m * 10K).
Lokhu kusho ukuthi lapho kushisa, i-cylinder head inlet iba nkulu izikhathi ezi-2 kunekhandlela. Ngakho-ke, ku-motor efudumele, okusebenzisekayo kulula ukukhulula, ngoba ukucindezelwa kwe-inlet kuba buthaka. Kodwa ukufakwa kwengxenye entsha kufanele kwenziwe enjini epholile ukuze ukuqina kuhambisane nentambo yekhanda le-cylinder.
Ukuze ugweme izimo ezinjalo, ukulungiswa kufanele kwenziwe ekushiseni kwemoto okufanelekile, kucatshangelwa ama-coefficients wokwanda okushisayo kwezinto ezisetshenziswayo kanye nentambo yomthombo.
Ungawashintsha kanjani ama-spark plug: enjini ebandayo noma eshisayo
Ngokuhamba kwesikhathi, izinto ezisetshenziswayo ezizenzakalelayo ziyaguga futhi azikwazi ukwenza imisebenzi yazo ngokugcwele. Njalo uma uqala injini, ichopho lensimbi lekhandlela liyacishwa. Kancane kancane, lokhu kuholela ekwandeni kwegebe lenhlansi phakathi kwama-electrode. Ngenxa yalokho, kuvela izinkinga ezilandelayo:
- ukudubula kabi;
- ukuthungela okungaphelele kwengxube yamafutha;
- ukuqhunyiswa okungahleliwe kumasilinda kanye nesistimu yokukhipha umoya.
Ngenxa yalezi zenzo, umthwalo kumasilinda uyanda. Futhi izinsalela zikaphethiloli ezingashisiwe zingena ku-catalyst futhi zicekele phansi izindonga zayo.
Umshayeli ubhekene nenkinga yokucisha imoto, ukwanda kokusetshenziswa kukaphethiloli nokuphelelwa ngamandla enjini.
Isikhathi sokushintsha
Impilo yesevisi yezinto zokushisa incike ezintweni ezilandelayo:
- uhlobo lwezinto ezibonakalayo (nickel, isiliva, iplatinum, iridium);
- inani lama-electrode (uma ekhona, ama-misfire avamile);
- uphethiloli othululiwe namafutha (kusuka kumkhiqizo ompofu, ukugqokwa kwengxenye kungakhuphuka kufike ku-30%);
- isimo senjini (kumayunithi amadala anesilinganiso esiphansi sokucindezela, ukugqokwa kushesha izikhathi ezi-2).
Amakhandlela ajwayelekile enziwe ngethusi ne-nickel (ane-1-4 "amacembe") angahlala ukusuka kumakhilomitha ayi-15 kuya ku-30 ayizinkulungwane. Njengoba intengo yabo incane (cishe ama-ruble angu-200-400), kungcono ukushintsha lezi zinto zokusetshenziswa ngamafutha njalo nge-MOT. Okungenani kanye ngonyaka.
Ama-electrode esiliva abonakala ngokusebenza okuphezulu kwe-thermal. Ngenxa yalokhu, zihlala isikhathi eside izikhathi ezi-2 kunezinto ezijwayelekile zokuthungela. Umkhawulo wabo wokuphepha wanele amakhilomitha ayizinkulungwane ezingu-30-40 noma iminyaka engu-2 yokusebenza.
Amathiphu ane-platinum kanye ne-iridium ayazihlanza ngokwawo kumadiphozithi ekhabhoni futhi aqinisekisa inhlansi engaphazamiseki emazingeni okushisa aphezulu. Ngenxa yalokhu, bangasebenza ngaphandle kokwehluleka amakhilomitha ayizinkulungwane ezingu-90 (kuze kube yiminyaka engu-5).
Abanye abanikazi bezimoto bakholelwa ukuthi kungenzeka ukwandisa impilo yesevisi yezinto ezisetshenziswayo izikhathi ezingu-1,5-2. Ukuze wenze lokhu, ngezikhathi ezithile yenza lezi zinyathelo ezilandelayo:
- susa umule nokungcola ngaphandle kwe-insulator;
- hlanza i-carbon deposit ngokushisa ithiphu ku-500 ° C;
- lungisa igebe elandisiwe ngokugoba i-electrode eseceleni.
Le ndlela yokusiza umshayeli uma engenalo ikhandlela eliyisipele, futhi imoto imile (isibonelo, ensimini). Ngakho ungakwazi "ukuvuselela" imoto futhi ufike esiteshini sesevisi. Kodwa akukhuthazwa ukukwenza ngaso sonke isikhathi, njengoba ingozi yokuphuka kwenjini ikhula.
Izinga lokushisa elidingekayo
Lapho wenza ukulungiswa, kubalulekile ukucabangela i-coefficient yokwandisa ukushisa. Uma i-spark plug yenziwe ngensimbi futhi umthombo wenziwe nge-aluminium, khona-ke ingxenye endala isuswa enjini ebandayo. Uma inamathela, imoto ingafudunyezwa imizuzu engu-3-4 ukuya ku-50 ° C. Lokhu kuzokhulula ukucindezelwa komthombo.
Ukushintshwa kwepulaki yenhlansi yenjini
Ukudilizwa emazingeni okushisa aphezulu kakhulu noma aphansi kuyingozi. Ukusebenza okunjalo kuzophula uxhumo oluluchungechunge futhi kulimaze ikepisi yocingo. Ukufakwa kwengxenye entsha kwenziwa ngokuqinile enjini epholile, ngakho-ke othintana naye uzohamba ncamashi nentambo.
Izincomo ezengeziwe
Ukuze amakhandlela angaphumeleli kusenesikhathi, kuyadingeka ukugcwalisa imoto ngephethiloli namafutha aphezulu kuphela.
Akufanele uthenge izinto ezisetshenziswayo zemikhiqizo engaziwa (kunezinkohliso eziningi phakathi kwazo). Kungcono ukubonisana nochwepheshe. Okuncamelayo kunikezwa emikhiqizweni ye-multi-electrode ene-iridium noma i-platinum sputtering.
Uma kuphakama umbuzo: kukuphi ukushisa okulungile ukufaka esikhundleni sekhandlela, ngakho-ke konke kuncike esiteji sokulungisa kanye nohlobo lwempahla yengxenye. Uma i-consumable endala yenziwe ngensimbi, bese isuswa enjini epholile noma efudumele. Ukufakwa kwezinto ezintsha kwenziwa ngokuqinile enjinini ebandayo.
