1. Crank yekubatanidza tsvimbo michina

Iyo crank yekubatanidza tsvimbo michina inoumbwa necylinder block, cylinder head, piston, yekubatanidza tsvimbo, crankshaft uye flywheel. Iyi ndiyo injini inogadzira simba uye inoshandura mutsara unodzokorodza kufamba kwepiston kuita kutenderera kwe crankshaft kuburitsa simba kunze.

2. Valve mechanism

Iyo nzira yevharuvhu inoumbwa nevharuvhu yekupinda, vharafu yekupedza, valve chitubu, tappet, camshaft uye nguva giya. Basa rayo nderekuzadza silinda negasi nyowani munguva uye kuburitsa gasi rekuburitsa rinogadzirwa nekupisa munguva.

3. Fuel supply system

Iyo dizeli injini yemafuta yekugovera system inoumbwa nemafuta tangi, pombi yemafuta, pombi jekiseni remafuta, dizeli sefa, nezvimwe. Basa rayo nderekupa mweya wakachena kune cylinder uye kupinza imwe chiyero chedhiziri mucylinder panguva yakatarwa kugadzirisa. iyo injini yekubuda simba uye kumhanya. Pakupedzisira, gasi rekupedza mushure mekupisa rinobudiswa kubva muhumburumbira.

4. Intake system

Chinodiwa chakakosha chegadziriro yekutora ndechekupa mweya wakachena wakawanda sezvinobvira kune injini. Iyo mhepo yekudyara modhi inogona kukamurwa kuita yechisikigo aspiration, supercharging, supercharging intercooling, uye mbiri supercharging intercooling. Iyo sisitimu inonyanya kuumbwa nemhepo sefa, pombi yekupinda, cylinder head airway, etc. Basa guru remhepo sefa ndeyekusefa kunze tsvina uye guruva mumhepo kuve nechokwadi chekuchena kwemhepo inopinda mucylinder kuti iwedzere hupenyu hwebasa. zveinjini.

5. Kutonhora system

Injini dzedhiziri dzinowanzoshandisa kutonhora kwemvura. Mhando yekutonhodza mvura ine pombi yemvura, radiator, feni, thermostat, uye bhachi remvura (mumuviri). Basa rayo ndere kushandisa kutenderera kwemvura inotonhorera kubvisa kupisa kwepamusoro-tembiricha zvikamu mumhepo kuburikidza neradiator, nekudaro kuchengetedza yakajairika tembiricha yeinjini. Iyo dhiziri inoiswa mukamuri yekupisa yeinjini yedhiziri inoburitsa huwandu hukuru hwekupisa; chinenge chikamu chimwe muzvitatu chayo chinoshandurwa kuita mechanical simba kuburikidza nepiston uye yekubatanidza tsvimbo nzira, uye inoshanda kunze; chikamu chimwe chete muzvitatu chinobudiswa nemhepo; chikamu chimwe muzvitatu chinorasika negadziriro yekutonhodza.

6. Lubrication system

Iyo lubrication system ine pombi yemafuta, sefa, chiteshi chemafuta, pani yemafuta, nezvimwe. Basa reiyo lubrication system kuendesa huwandu, hwakachena, uye zvakakodzera viscous lubricating mafuta kune ese anodiwa kuti aderedze kukwesha, kunonoka. kupera kwezvikamu, uye kuchenesa nekutonhodza nzvimbo yekukwenya. Inoita basa rinokosha mukuvimbika uye kusimba kweinjini dzedhiziri, kusanganisira: kuderedza kupera kwezvikamu uye kuderedza basa rekukwenya; kutonhora uye kuchenesa nzvimbo yekuzora; kudzivirira ngura munzvimbo iyo firimu yemafuta inoshambadzirwa; uye kupa hydraulic medium.

7. Kutanga hurongwa

Iyo yekutanga sisitimu ine bhatiri, waya, solenoid cut-off valve, yekutanga switch, inotangira, uye charger, iyo inoshandiswa kutanga injini yakamira uye kuishandura kuita inozvimiririra kushanda.
