Chiyambi cha injini ya Mafuta

Nchiyani chimayambitsa over-pressurization?
Kuthamanga kwambiri kwamafuta a injini ndi chifukwa cha valavu yolakwika yoyendetsera mafuta.Kuti mulekanitse bwino magawo a injini ndikupewa kuvala kopitilira muyeso, mafuta ayenera kukhala opanikizika.Pampu imapereka mafuta pamagetsi ndi kupsinjika kwakukulu kuposa zomwe dongosolo limafunikira kuti lizipaka mafuta ndi magawo ena osuntha.Valve yowongolera imatsegulidwa kuti ma voliyumu ochulukirapo ndi kukakamiza kutembenuke.
Pali njira ziwiri zomwe valve imalephera kugwira ntchito bwino: mwina imamatira pamalo otsekedwa, kapena imachedwa kusunthira kumalo otseguka injini itangoyamba.Tsoka ilo, valavu yomata imatha kudzimasula yokha pambuyo pakulephera kwa fyuluta, osasiya umboni wa vuto lililonse.
Chidziwitso: Kuthamanga kwambiri kwamafuta kungayambitse kusinthika kwa fyuluta.Ngati valavu yoyang'anira ikadali yokhazikika, gasket pakati pa fyuluta ndi maziko akhoza kuphulika kapena msoko wa fyuluta udzatsegulidwa.Dongosololi lidzataya mafuta ake onse.Pofuna kuchepetsa chiopsezo cha makina oponderezedwa kwambiri, oyendetsa galimoto ayenera kulangizidwa kusintha mafuta ndi fyuluta nthawi zambiri.

Kodi ma valve mu dongosolo la mafuta ndi chiyani?
1. Vavu Yowongolera Kupanikizika kwa Mafuta
2. Vavu ya Relief (Bypass).
3. Anti-Drainback Valve
4. Vavu ya Anti-Siphon

Kodi Zosefera Amayesedwa Motani?
1. Zoyezera Zomangamanga Zosefera.Kuyeza bwino kuyenera kutengera mfundo yakuti fyulutayo ilipo pa injini kuti ichotse tinthu tambiri tomwe timayambitsa kuwonongeka kotero kuti iteteze injini kuti isawonongeke.
2. Kuthekera kwa Zosefera kumayesedwa mu mayeso ofotokozedwa mu SAE HS806.Kuti mupange fyuluta yopambana, kulinganiza kuyenera kupezeka pakati pa kuchita bwino kwambiri ndi moyo wautali.
3. Cumulative Efficiency imayesedwa panthawi ya kuyesa mphamvu ya fyuluta yochitidwa ku SAE standard HS806.Kuyesa kumayendetsedwa ndikuwonjezera mosalekeza zoipitsa zoyeserera (fumbi) kumafuta omwe amazungulira pasefa.
4. Multipass Mwachangu.Njirayi ndi yomwe yapangidwa posachedwa kwambiri mwa atatuwa ndipo imayendetsedwa ngati njira yovomerezeka ndi mabungwe apadziko lonse lapansi komanso aku US.Zimaphatikizapo kuyesa kwatsopano
5. Mayesero amakina ndi Durability.Zosefera zamafuta zimayesedwanso kangapo kuti zitsimikizire kukhulupirika kwa fyuluta ndi zigawo zake panthawi yoyendetsa galimoto.
6. Single Pass Efficiency imayesedwa muyeso yotchulidwa ndi SAE HS806.Pakuyesa uku fyuluta imapeza mwayi umodzi wokha wochotsa zodetsa m'mafuta
