Dururira mafuta edhiziri muinjini yepeturu. Migumisiro uye wongororo

Misiyano yekushanda pakati pediziri nepeturu injini

Pane misiyano mishoma inoenderana zvakananga nemafuta einjini pakati pedhiziri nepeturu. Ngatizvifungei.

1. Higher compression ratio. Paavhareji, mhepo iri muhumburumbira yeinjini yedhiziri inomanikidzwa 1,7-2 nguva yakasimba. Izvi zvinodiwa kupisa mhepo kusvika kune tembiricha yedhiziri. Iyo yakakwira dhigirii yekumanikidza inotaridza yakawedzera mitoro pazvikamu zve crankshaft. Muchiitiko ichi, mafuta ari pakati pemajenari e shaft uye ma liner, pamwe nepakati pepini nenzvimbo yekugara papiston, inosangana nemitoro yakakura.
2. Higher average tembiricha. Kupisa kwemoto painjini yedhiziri kwakati kwakakwira, sezvo tembiricha yepamusoro yakatosimbiswa mukamuri yekupisa panguva yekumanikidza sitiroko. Muinjini yepeturu, peturu inopfuta chete inopa kupisa.

3. Yakaderedzwa avhareji yekumhanya. Injini yedhiziri haiwanzo kutenderera kusvika ku5000-6000 zviuru zvekuchinja. Ndichiri pa peturu, iyi crankshaft kumhanya inosvikwa kazhinji.
4. Kuwedzera kuparadzaniswa kwedota. Nekuda kwesarufa yemhando yemafuta edhiziri, sulfur oxides inoumbwa muinjini yedhiziri, iyo inopinda zvishoma mumafuta.

Kune mimwe misiyano yakati wandei isina kukosha. Asi isu hatizozvifungidzire, sezvo dzinenge dzisingabatsiri pane zvinodiwa zvemafuta einjini.

Mafuta edhiziri akasiyana sei nepeturu?

Mafuta einjini einjini dzedhiziri uye peturu ICEs, zvisinei nemafungiro asiriwo akajairika pakati peruzhinji, anosiyana zvishoma mukuumbwa uye zvivakwa. Mafuta ekutanga uye chikamu chikuru chekuwedzera pasuru zvakafanana. Musiyano uri muzvikamu zvishoma chete.

1. Diesel oiri ine yakasimbiswa pasuru yezvinowedzera zvakagadzirirwa kusaita maturu esarufa uye zvakanyanya kushingaira kugeza madhipoziti. Mafuta epeturu ari kuderera zvakanyanya panyaya iyi. Asi nekuda kweizvi zvinowedzera, mafuta edhiziri anowanzo ane yakawedzera sulfate ash content. Pamafuta emazuva ano, dambudziko iri rinogadziriswa nekuvandudza madhigirii ekugadzirisa izvo zvisingawedzere madota.
2. Mafuta edhiziri akayerwa zvakanyanya pakudzivirira kwemafuta ekuputitsa firimu pane yekumhanyisa shear. Misiyano iyi haina kukosha uye pasi pemamiriro enguva dzose hazviratidzike nenzira ipi zvayo.
3. Kuvandudzwa kwemafuta kuramba kune oxidation. Kureva, mumafuta edhiziri, mwero weoxidation wakadzikira.

Kune mafuta edhiziri emotokari dzekutengesa uye dzemotokari dzinotakura vanhu. Zvekutakura vanhu, oiri akagadzirirwa kuwedzera kuchengetedzwa kweinjini nehupenyu hupfupi hwesevhisi. Kune marori uye dzimwe mota dzekutengesa, kusimbiswa kuri pane yakawedzerwa nguva yebasa.

Mhedzisiro yekudira mafuta edhiziri muinjini yepeturu

Mhedzisiro yekushandisa mafuta edhiziri mune peturu injini zvinoenderana nezvakawanda zvinhu. Ngatitarisei pane zvakajairika sarudzo.

• Kuzadza mafuta edhiziri nemvumo yemotokari dzinotakura vanhu (API CF, ACEA B3/B4) mumainjini akareruka epeturu emotokari dzeEurope neAmerica dzine zvidiki zvinodiwa. "Kutsiviwa" kwakadaro munyaya yakawanda kunobvumirwa, kunze kwekuti kuzadza kunoitwa kamwechete. Panguva imwecheteyo, zvinokurudzirwa kutsiva mafuta neakakodzera maererano nekutsanangurwa nekukurumidza. Muchiitiko chino, unogona kutyaira Diesel lubrication, asi hazvikurudzirwi kushandura injini pamusoro 5000 zviuru revolutions.
• Kuzadza mafuta edhiziri kumarori (API Cx yakatenderwa mota dzekutengesa kana ACEA Cx) mune chero mota yemufambi ine injini yepeturu kunoodzwa mwoyo zvakanyanya. Zvinokwanisika kushandisa mafuta edhiziri akadaro chete kana pasina imwe nzira, kwenguva pfupi (kune chiteshi chebasa chiri pedyo) uye pasi pemamiriro ekutyaira nemitoro mishoma.
• Kushandiswa kwemafuta edhiziri kumotokari dzemazuva ano dzeAsia dzakagadzirirwa mafuta akaderera-viscosity zvinorambidzwa zvachose. Mafuta akakora einjini dzedhiziri haafambe zvakanaka nemumatanho akatetepa emafuta uye anoshanda zvisina kunaka mukubata mapeya ekukweshera ane kucheneswa kwakaderedzwa. Izvi zvinokonzeresa nzara yemafuta uye zvinogona kutungamira mukubatwa kweinjini.

Paunenge uchishandisa mafuta edhiziri mumajini epeturu, zvakakosha kuti urege kupisa injini uye usaitenderedza kusvika pakumhanya.
