Chigadziko cheMabhurashi ePeturu maviri

Maitiro ekusarudza mafuta ekushandisa injini yekucheka mabhurashi epeturu

1. Oiri yeinjini dzemhando mbiri

Injini ine mavhiri maviri inoshandisa musanganiswa wepeturu nemafuta einjini semafuta. Peturu nemafuta einjini zvinofanira kusanganiswa zvakaenzana kuti mafuta einjini anyungudutswe zvakaenzana mupeturu. Kana mafuta akawandisa akapinda musirindiri panguva yakati, zvinoita kuti mafuta acho aome kubatidza uye zvichiita kuti injini imire kushanda. Panguva imwe chete, mafuta akawandisa anogonawo kukonzera kuti ma spark plugs nema piston rings zviunganidze kabhoni; Kana mafuta akawandisa, madziro esirinda haagone kuzorwa mafuta, zvichiwedzera kupera, zvichikonzera "kudhonza masirinda" uye kukonzera tsaona dzakakomba.

Chiyero chemafuta akasanganiswa imhando yemafuta einjini maviri: peturu = 1:25. Peturu ine giredhi re90 # kana kupfuura inokurudzirwa, uye 93 # inokurudzirwa. Mafuta einjini maviri anoshandiswa, uye mafuta einjini mana anorambidzwa zvachose.

Zvinokurudzirwa kushandisa mafuta einjini akasarudzika ane chiyero che1:40 mumaawa makumi matatu ekutanga emuchina mutsva, wobva washandisa chiyero chakajairika che1:25 mushure memaawa makumi matatu. Hazvibvumirwi kudarika 1:25, zvikasadaro huwandu hwacho hwakanyanya kutetepa uye hunogona kukonzera kuti muchina udhonze silinda. Ndapota teverai zvakanyatsonaka chinoshandiswa chemafuta chakapihwa nemuchina kuti mubudise mafuta, uye musabudise mafuta zvisina tsarukano zvichienderana nefungidziro. Mafuta akasanganiswa anofanira kugadzirwa uye kushandiswa ipapo ipapo, uye zvinorambidzwa zvakanyanya kushandisa mafuta akasanganiswa akagadzirwa kwenguva yakareba.

2. Oiri yeinjini dzema "stroke" mana

Usatange tangi remafuta usina kuwedzera mafuta. Basa guru remafuta nderekuisa mafuta munzvimbo dzinofamba dzeinjini yepeturu, kuitonhodza nekuitonhodza, kuichenesa, uye kudzivirira ngura. Hunhu uye kushandiswa kwakakodzera kwemafuta einjini hakungokanganisi mashandiro uye hupenyu hwebasa reinjini yepeturu chete, asiwo kunokanganisa hupenyu hwebasa remichina. Saka, mhando dzakakodzera dzemafuta einjini dzinofanira kusarudzwa zvichienderana nekupisa kweinjini yepeturu.

Pakupisa kwakaderera, oiri yeinjini inofanira kunge iine kuyerera kwakanaka, uye pakupisa kwakakwira, inofanira kunge iine kinematic viscosity yakakodzera, iyo inonyanya kukosha kune mainjini epeturu anotonhorerwa nemhepo. Zvisinei, nekuda kwehukuru hudiki hweinjini yechina yebrashi cutter uye kugona kwayo kushoma, pamwe nekumhanya kwakanyanya, inoda mafuta akawanda. Zvinorambidzwa kushandisa oiri isina kunaka, uye zvinokurudzirwa kushandisa oiri yakasarudzika kumichina yemubindu.

Wedzera mafuta einjini ye4T akakodzera mutangi remafuta, isa muchina pasi, uye huwandu hwemafuta hunofanira kusvika pakuzadza tangi remafuta husingafashukire. Tarisa huwandu hwemafuta usati watanga kushanda kuti uve nechokwadi chekuti muchina wacho wanyorova zvakanaka.

Mafuta einjini ine injini ine injini ina anoshandiswa peturu chete, ane giredhi re90 # kana kupfuura. Zvinokurudzirwa kushandisa peturu re93 #. Kuisa peturu muinjini dzinopisa hakubvumirwi, uye kusvuta hakubvumidzwe zvachose panguva yekuisa peturu.

Muzhizha rinopisa, nekuda kwekupisa kwakanyanya uye kumanikidzwa kwemhepo kwakaderera, kusapindirana kwemhepo kunowanzoitika, uye zvakakosha kusimbisa kupararira kwekupisa kweinjini uye kudzivirira mapaipi emafuta.

Usashandise peturu ine lead yakawedzerwa semafuta ekuchenesa kudzivirira chepfu ye ethyl lead. Usashandise peturu yagara yakachengetwa kwenguva yakareba uye yaora, zvikasadaro inokonzera coking yakakura uye carbon deposition. Flash point yepeturu yakaderera zvikuru, inobvira moto, inoputika, uye inokwanisa kugadzira magetsi asingachinji. Inofanira kushandiswa zvinoenderana nemitemo uye kuchengetwa zvakachengeteka.
