Spark plugs: mhando, saizi, misiyano

Nhasi, nhamba huru yemhando dze spark plugs dzinogadzirwa. Zvigadzirwa zvemugadziri wega wega zvine maitiro avo. Isu takatonyora nezvevazhinji vavo pawebhusaiti yedu Vodi.su patakafunga nezve mazita avo.

Iwo makuru ma parameter ayo marudzi emakenduru anosiyaniswa nawo:

• nhamba ye electrodes - imwe chete kana yakawanda-electrode;
• zvinhu kubva iyo inonzi electrode yepakati inogadzirwa yttrium, tungsten, platinum, iridium, palladium;
• kupenya nhamba - "inotonhora" kana "makenduru anopisa.

Kune zvakare misiyano yechimiro, muhukuru hwepakasiyana pakati pedivi nepakati electrode, mune diki dhizaini maficha.

Standard kenduru

Iyi ndiyo inonyanya kuwanikwa uye inowanikwa zvakanyanya. Chishandiso chebasa rake hachina kunyanya kukura, iyo electrode inogadzirwa nesimbi isingadziviriri, saka nekufamba kwenguva, maratidziro ekukukurwa anoonekwa pairi. Sezvineiwo, mitengo yakadzikira, saka kuitsiva hakuzodhure zvakanyanya.

Muchidimbu, makenduru ese ekugadzirwa kwepamba, semuenzaniso, iyo Ufa chirimwa, inogona kuverengerwa kune yakajairwa - A11, A17DV, inoenda ku "penny". Zvinokurudzirwa kutarisa mhando yavo pasina kusiya reji remari, nekuti chikamu chehurema chinogona kunge chakanyanya kukwirira. Zvakangodaro, kana ukasarudza zvakanaka uye zvemhando yepamusoro zvigadzirwa, ivo vanogadzira yavo sosi pasina matambudziko.

Usakanganwa zvakare kuti hupenyu hwebasa hunokanganiswa zvakanyanya nemamiriro einjini. Vanogona kuumba madhipoziti emavara akasiyana, ayo anoratidza kusashanda kweinjini, semuenzaniso, kuumbwa kweakaonda kana akapfuma emhepo-mafuta musanganiswa.

Multi-electrode makenduru

Mune makenduru akadaro kune akawanda emativi emagetsi - kubva maviri kusvika mana, nekuda kwekuti hupenyu hwebasa hunowedzera zvakanyanya.

Mainjiniya vakauya nepfungwa yekushandisa akawanda emagetsi epasi, nekuti imwe electrode inopisa zvakanyanya panguva yekushanda, iyo inoderedza zvakanyanya hupenyu hwayo hwebasa. Kana ma electrode akati wandei achibatanidzwa, saka anoshanda sekunge ariwo, zvichiteerana, hapana kupisa.

Zvinonakidzawo kuti mainjiniya eSweden mota kambani SAAB vakaronga vachishandisa yakanongedza uye yakareba chikamu papiston pachayo pachinzvimbo chedivi electrode. Kureva, kenduru inowanikwa pasina divi electrode zvachose.

Zvakanakira sarudzo yakadaro zvakawanda:

• spark ichaonekwa panguva yakakodzera apo piston inosvika panzvimbo yepamusoro yakafa;
• mafuta achapisa anenge asina kusara;
• misanganiswa yakaonda inogona kushandiswa;
• kuchengetedza kwakakosha uye kuderedza kwehutsi hunokuvadza mumhepo.

Kunyange izvi zvichiri zvirongwa zvenguva yemberi, ma-multi-electrode spark plugs anoshandiswa pamotokari dzemujaho, izvo zvinoratidza hunhu hwavo. Chokwadi, uye mutengo wakakwirira. Zvakadaro, single-electrode iri kuvandudzwa zvishoma nezvishoma, saka zvakaoma kutaura zvisina mubvunzo kuti ndezvipi zviri nani.

Iridium uye platinum spark plugs

Vakatanga kuoneka muna 1997, vakaburitswa neDENSO.

Distinctive properties:

• iyo yepakati electrode yakagadzirwa neiridium kana platinum ine hupamhi hwe 0,4-0,7 mm chete;
• iyo electrode yeparutivi inonongedza uye yakanyorwa nenzira yakakosha.

Kubatsira kwavo kukuru ndehupenyu hurefu hwebasa, hunogona kusvika makiromita 200 zviuru kana makore 5-6 ekushanda kwemotokari.

Ichokwadi, kuitira kuti vashande zvizere pfuma yavo, zvinodikanwa kutevedzera mirairo yemugadziri:

• shandisa mafuta ane octane rating isiri pasi pane inotsanangurwa mubhuku;
• ita kuiswa zvakasimba maererano nemitemo - simbisa kenduru kusvika pane imwe nguva, kana iwe ukakanganisa, ipapo mugumisiro wose uchave wakanyatsogadziriswa.

Kuita kuti zvive nyore kuputira makenduru akadaro mumusoro wehumburumbira, vagadziri vanoisa zvimiso zvakakosha zvinodzivirira kuti vasasimbiswe zvakanyanya kupfuura zvinodiwa.

Chinhu chakashata chete ndiyo mari yakakwirira. Zvakakoshawo kuziva kuti iridium ine hupenyu hurefu hwebasa kupfuura platinum, uye naizvozvo mutengo wayo wakakwirira.

Sezvo mutemo, maJapan automakers anokurudzira kushandisa rudzi urwu rwekenduru kumotokari dzavo. Izvi zvinonyanya kushanda kuToyota Camry uye Suzuki Grand Vitara.

Makenduru ane nechepakati electrode akagadzirwa zvimwe zvinhu zvakare anogara kwenguva refu kupfuura mwero, asi havasi vakawanda kuwanikwa pamusika.
