Lienjine tsa Volvo B4184S, B4184S2, B4184S3
Tse ka hare
Bahahi ba lienjine tsa Sweden bohareng ba lilemo tsa bo-90 ba ile ba qapa le ho hlahisa mofuta o mocha oa lienjineri tsa modular. Li ne li khetholloa ka compactness e phahameng, sesebelisoa se bonolo 'me, joalokaha nako e bontšitse, ho tšoarella.
tlhaloso
Enjene ea modular 4-cylinder e kentsoe ho tloha ka 1995 molokong oa pele oa Volvo S40 le Volvo V40. Ho qala ha letoto le lecha la li-unit tsa matla ho ile ha beoa ke B4184S motor. Mofuta oa enjene o hlalosoa ka tsela e latelang: B - peterole, 4 - palo ea li-cylinders, 18 - molumo o pota-potiloeng (1,8 litha e le nngwe), 4 - palo ea li-valve ka cylinder, S - sepakapaka le nomoro ea ho qetela e bolela moloko (phetolelo) ea sehlahisoa (mohlala ona ha a eo).
Letsibolo la letoto la B4184S le entsoe ke baenjiniere ba Volvo Group. E entsoe fekthering ea Skövde, Sweden. Ke enjene e hahelletsoeng ka peterole e nang le lisilindara tse 'ne e nang le bophahamo ba lilithara tse 1,8.
E kentsoe likoloing tsa Volvo tsa moloko oa pele oa S40 le V40 ho tloha 1995 ho isa 1999.
The cylinder block e entsoe ka aluminium, li-liner ke tšepe e entsoeng ka tšepe.
Hlooho ea silinda e boetse ke aluminium, likarolo tse peli. Karolo e ka tlase e boloka terene ea li-valve le libere tsa camshaft. Likamore tse tukang li na le hemispherical, tokisetso ea valve ke V-shaped. Li-valve li tloaelehile. Li-chamfer tse sebetsang tsa li-valve tsa ho qeta li na le seaparo sa stellite. Li-hydraulic pushers lia ikemela.
Mantsoe a seng makae ka li-hydraulic lifters. Liphetoho tse nkiloeng tsa lienjine ha li. Empa hangata Inthaneteng u ka fumana boitsebiso bo mabapi le ho fumaneha ha tsona. Ho lumela eng? Karabo e bonolo. Li-comensator tsa Hydraulic li ne li na le lienjineri, ho kenyeletsoa le B4184S, tse sebetsang ho latela molao-motheo oa GDI. Ka mefuta ea bona ea mohlala, ba ne ba e-na le index ea M, ke hore. eseng B4184S, empa B4184SM. Ka bomalimabe, "litsebi" tse ling ha lia ka tsa ela hloko "trifle" ena (lengolo M) mme tsa bolela hore ho na le li-hydraulic lifters holim'a enjene. Ho ba le ho tšoana ho feletseng ka ponahalo, e neng e khelosa, e ne e ntse e le likarolo tse fapaneng tsa matla.
Li-piston li tloaelehile. Melamu e kopanyang tšepe, e entsoeng.
Ho tsamaisa lebanta la nako. Khatello ea lebanta e iketselitse.
Pompo ea oli ea sistimi ea lubrication e behiloe holim'a crankshaft. Gear.
Sistimi ea phepelo ea mafura - ente. Tsamaiso e etsoa ke module ea Fenix 5.1.
moo: 1- Fenix 5.1 taolo ea module; 2- valve ea ho koala; 3- hlahloba valve; 4- valve ea solenoid; 5- pompo ea moea; 6- phepelo ea pompo ea moea.
Enjene ea B4184S2 e se e le matla ho feta ea pele ho eona.
Sena se fihletsoe ka lebaka la ntlafatso e nyane. Pele ho tsohle, ka lebaka la ho eketseha ha molumo. Ho fihlela sena, sekhahla sa piston se ile sa eketseha ka 2,4 mm.
Phetoho e latelang e ile ea ama phetoho ea nako ea li-valve. Phetoho ea bona e etsahala nakong ea ho noa, ho itšetlehile ka mekhahlelo ea enjene. Qetellong, ntlafatso ena e ile ea kenya letsoho ho eketseheng ha matla, torque, moruo oa mafura le ho fokotsa ho ntšoa ha likhase tse kotsi.
Li-coil tsa motho ka mong li ne li kentsoe likerese.
Enjene e ne e reretsoe ho kenya likoloi tsa Volvo S40 le Volvo V40 ho tloha 1999 ho isa 2004.
Sesebelisoa sa motlakase sa moloko oa boraro B4184S3 se entsoe ho tloha 2001 ho isa 2004.
E ne e fapane le ea pele ho eona ka sistimi e tsoetseng pele ea ho feto-fetoha ha nako (CVVT). Phetoho e entse hore ho khonehe ho eketsa ts'ebetso ea enjene haholo, le ho fokotsa tšebeliso ea mafura ka tekanyo e kholoanyane, le ho fokotsa khatello ea likhase tse kotsi ho tsoa.
Phapang ea bobeli e ne e le ho fokotseha ho fokolang ha boima ba li-cylinder block, e leng se ileng sa lebisa ho fokotseha ha boima ba enjene.
Enjene e kentsoe likoloing tsa Volvo S40 le Volvo V40.
