Injini mafuta

injini mafuta - ndi mtundu wa injini kuyaka mkati, imene wothinikizidwa mafuta akayaka ndi mphanvu chiyambi magetsi. Mphamvu mwa iwo kuyang'aniridwa ndi olamulidwa ndi kusintha otaya mpweya.

Mafuta injini poyerekeza ndi dizilo ali ndi liwiro lalikulu ndi buku (lita) mphamvu, ndi kugwedera ndi phokoso - mwake, pansipa. The osakaniza kuyaka kumalamuliridwa makamaka quantitatively chifukwa mphamvu otsika ndi pafupifupi (yachibadwa ntchito ya galimoto) zothandiza otsika psinjika. Choncho, pali ofooka kuyaka dzuwa ndi kutsatira patsogolo izo - choncho chidwi mafuta.

Iwo likukhalira kuti ndi mphamvu mwadzina dzuwa la injini zimenezi pa poyerekeza 20% dizilo. Mu mode tsankho kusiyana ndi 40% kapena zambiri. Zimenezi wakhala mobwerezabwereza anatsimikizira poyerekeza mayesero ntchito ndi mayesero a magalimoto ndi mitundu onse a injini mphamvu ofanana.

Ngati ife kulankhula za mlingo wa kawopsedwe malasha utsi wa zinthu gaseous, angathe ananena kuti chifukwa patsogolo injini mafuta mu khumi zapitazo, chithunzi ichi chinali bwino kwambiri. Iwo wasinthira ndi olamulidwa ndi purosesa pisitoni lalifupi jekeseni mwachindunji kudzera nozzles. Pa nthawi yomweyo, malinga ndi zimene akatswiri ambiri odalirika ku makampani kutsogolera magalimoto, kulingana panopa zofuna mkulu miyezo kuteteza zachilengedwe ndi malo injini petulo akadali wolephera injini dizilo - kwambiri zingamuthandize ndipo amakumana pamwamba amafuna injini. Komabe, khama kuonetsetsa ndi bwino ntchito chilengedwe choyamba sasiya.

Ngati galimoto ali okonzeka ndi injini mafuta, ndiye bwinobwino amapezeka 4 ntchito sitiroko:

• Inlet. Pamene a pisitoni wa lina panalembedwa ukusunthira pansi ndi injini, ngati mpope, kudzera valavu lotseguka "imayamwa" petulo ndi mpweya.
• Psinjika. Onse mavavu - ndi polowera ndi kubwereketsa - atsekedwa. Tsopano, pisitoni limatuluka oposa, compressing chisakanizo cha mpweya ndi mafuta. Kumapeto kwa izi sitiroko pulagi mphanvu amapanga mphamvu zomwe uyatsa osakaniza kale wothinikizidwa.
• Sitiroko. Komabe chatsekedwa vavu wambiri vavu utsi, mafuta Watenthedwa. kuyaka mankhwala ndi mofulumira kukula voliyumu, chifukwa chimene amakankhira kwa pisitoni pansi. The pisitoni Zikatero, amayendetsa ndi crankshaft kudzera ndodo kulumikiza.
• Utsi. The pisitoni adzawuka kachiwiri. Valavu utsi chikuyamba ndi mpweya utsi ili mu dongosolo utsi, ndiyeno - m'mlengalenga.

Pali zina za opaleshoni ndi injini mafuta. Mavuto chifukwa cha zimene angafunikire injini kukonza petulo - mafuta otsika-quality, wolephera kapena osauka khalidwe yokonza, mkulu mtunda. Pakuti kukonza, lemberani mosungira katswiri, kumene odziwa amisiri malinga ndi zofunika za mitundu yonse mankhwala ndi makadi zamakono, zomwe zonse ntchito zonse yokonza aliyense makina kapena mfundo.

Polongosola mwachidule, m'pofunika kukhazikitsa phindu, amene amakhala ndi injini mafuta. Choyamba, ndi - mphamvu ndi yofanana. Ichi ndi chifukwa Mwachangu mkulu mphamvu ya mafuta ankadya - mafuta kapena Mowa. Komanso, injini mafuta yokha ali ndi mamangidwe mophweka ndi mtengo n'chozama kupitirira mtengo wa dizilo. Ndipo, ndithudi, izo zimayendera mwakachetechete, amene makamaka ayamba kuzindikira ziziyenda peresevshie kwa mafuta galimoto dizilo, chifukwa iwo sangathe ntchito akulu galimoto kuthamanga.
