Chodulira Burashi cha Petroli cha Stroke 2

Momwe mungasankhire mafuta a injini kwa odulira maburashi a petulo

1. Mafuta a injini zoyendera maulendo awiri

Injini yamagetsi yokhala ndi ma stroke awiri imagwiritsa ntchito mafuta osakaniza a petulo ndi mafuta a injini ngati mafuta. Mafuta a petulo ndi mafuta a injini ayenera kusakanizidwa mofanana kuti mafuta a injini asungunuke mofanana mu mafutawo. Ngati mafuta ambiri alowa mu silinda panthawi inayake, zimapangitsa kuti mafutawo aziyaka ndipo injiniyo isagwire ntchito. Nthawi yomweyo, mafuta ochulukirapo angayambitsenso kuti ma spark plugs ndi ma piston rings azisonkhanitsa kaboni; Ngati mafuta ochepa kwambiri, khoma la silinda silingathe kupakidwa mafuta, zomwe zimapangitsa kuti mafuta aziwonongeka kwambiri, zomwe zimapangitsa kuti "silinda ikoke" ndikuyambitsa ngozi zazikulu.

Chiŵerengero cha mafuta osakaniza ndi mafuta apadera a injini awiri: mafuta = 1:25. Mafuta okhala ndi giredi ya 90 # kapena kupitirira apo ndi omwe amalimbikitsidwa, ndipo 93 # ndi omwe amalimbikitsidwa. Mafuta a injini awiri amagwiritsidwa ntchito, ndipo mafuta a injini anayi ndi oletsedwa mwamphamvu.

Ndikoyenera kugwiritsa ntchito mafuta apadera a injini okhala ndi chiŵerengero cha 1:40 kwa maola 30 oyambirira a makina atsopano, kenako gwiritsani ntchito chiŵerengero chabwinobwino cha 1:25 patatha maola 30. Sikololedwa kupitirira 1:25, apo ayi kuchuluka kwake kumakhala kochepa kwambiri ndipo kungapangitse makina kukoka silinda. Chonde tsatirani mosamala chotsukira mafuta chomwe chili ndi makina kuti mutulutse mafuta, ndipo musatulutse mafuta mosasamala malinga ndi kuyerekezera. Mafuta osakaniza ayenera kukonzedwa ndikugwiritsidwa ntchito nthawi yomweyo, ndipo ndikoletsedwa kugwiritsa ntchito mafuta osakaniza omwe akhala akukonzedwa kwa nthawi yayitali.

2. Mafuta a injini zinayi zoyendera

Musayatse thanki yamafuta popanda kuwonjezera mafuta. Ntchito yayikulu yamafuta ndikuyika mafuta m'malo oyenda a injini yamafuta, kuziziziritsa ndikuziziritsa, kuziyeretsa, ndikuletsa dzimbiri. Ubwino ndi kugwiritsa ntchito bwino mafuta a injini sikuti kumakhudza magwiridwe antchito ndi moyo wa injini yamafuta, komanso kumakhudza moyo wa makina. Chifukwa chake, mafuta oyenera a injini ayenera kusankhidwa kutengera kutentha kwa injini yamafuta.

Pa kutentha kochepa, mafuta a injini ayenera kukhala ndi kusinthasintha kwabwino, ndipo pa kutentha kwakukulu, ayenera kukhala ndi kukhuthala koyenera kwa kinematic, komwe ndikofunikira kwambiri pa injini za petulo zoziziritsidwa ndi mpweya. Komabe, chifukwa cha kukula kochepa kwa injini ya brush cutter ya four stroke komanso mphamvu yochepa ya thanki yamafuta, komanso liwiro lalikulu logwira ntchito, imafuna mafuta ambiri. N'koletsedwa kugwiritsa ntchito mafuta otsika, ndipo tikulimbikitsidwa kugwiritsa ntchito mafuta apadera pamakina a m'munda.

Onjezani mafuta oyenera a injini ya 4T ku thanki yamafuta, ikani makinawo pansi, ndipo mulingo wa mafuta uyenera kufika pa malo odzaza mafuta osadzaza. Yang'anani mulingo wa mafuta musanayambe ntchito iliyonse kuti muwonetsetse kuti makinawo ali ndi mafuta okwanira.

Mafuta a injini ya ma stroke anayi ndi mafuta okhaokha, okhala ndi giredi ya 90 # kapena kupitirira apo. Ndikoyenera kugwiritsa ntchito mafuta a 93 #. Kudzaza mafuta m'ma injini otentha n'koletsedwa, ndipo kusuta fodya n'koletsedwa kwambiri panthawi yodzaza mafuta.

M'chilimwe chotentha, chifukwa cha kutentha kwambiri komanso mpweya wochepa, mpweya umakhala wovuta kupirira, ndipo ndikofunikira kulimbitsa kutentha kwa injini ndikuteteza mapaipi amafuta.

Musagwiritse ntchito mafuta owonjezera a lead ngati mafuta oyeretsera kuti mupewe poizoni wa ethyl lead. Musagwiritse ntchito mafuta omwe akhala akusungidwa kwa nthawi yayitali ndipo awonongeka, apo ayi angayambitse coking yayikulu komanso carbon dioxide. Malo oyaka a mafuta ndi otsika kwambiri, amatha kuyaka, kuphulika, komanso amatha kupanga magetsi osasinthasintha. Ayenera kugwiritsidwa ntchito motsatira malamulo ndikusungidwa bwino.
