Enjine ea Mitsubishi 6G72
Tse ka hare
Enjene ena ke ea Mitsubishi e tsebahalang letoto la 6G. Mefuta e 'meli ea 6G72 e tsejoa: 12-valve (camshaft e le' ngoe) le 24-valve (li-camshaft tse peli). Ka bobeli ke li-enjine tse 6-cylinder V tse nang le sekhahla se eketsehileng sa camber le li-camshaft / li-valve tse hloohong ea silinda. Enjene e bobebe e nkileng sebaka sa 6G71 e ile ea lula moleng oa kopano ka lilemo tse 22 hantle, ho fihlela ho fihla 6G75 e ncha.
Tlhaloso ea enjene
Nahana ka likarolo tse ka sehloohong tsa enjene ena.
- Enjene ea crankshaft e tšehetsoa ke li-bearings tse 4, likoahelo tsa tsona li kopantsoe betheng ho eketsa ho tiea ha cylinder block.
- Li-piston tsa enjine li lahleloa ho tsoa ho alloy ea aluminium, e hokahaneng ka phini e phaphametseng ho molamu o kopanyang.
- Mehele ea piston e entsoe ka tšepe e entsoeng ka tšepe: e 'ngoe e na le bokaholimo bo bosoeu bo nang le bevel.
- Mehele e kopantsoeng ea oli ea mokelikeli, mofuta oa scraper, o filoeng sehokelo sa selemo.
- Sehloohong sa cylinder, ho na le likamore tse tukang tsa mofuta oa litente.
- Li-valve tsa enjene li entsoe ka tšepe ea refractory.
- Li-compensator tsa Hydraulic li fanoa bakeng sa phetoho ea tumello ea othomathike ka har'a drive.
Phapano lipakeng tsa merero ea SOHC le DOHC e lokeloa ke tlhokomelo e khethehileng.
- SOHC version camshaft e entsoe, e nang le li-bearings tse 4, empa li-camshaft tsa mofuta oa DOHC li na le li-bearings tse 5 tse nang le likoahelo tse khethehileng.
- Lebanta la nako la enjene le nang le li-camshaft tse peli le lokisoa ke mochini o hatellang o ikemetseng. Li-roller li entsoe ka motsoako oa aluminium, li na le bophelo bo bolelele ba tšebeletso.
Re ela hloko likarolo tse ling.
- Bokhoni ba enjene ha bo fetohe bakeng sa liphetoho tse fapaneng - hantle lilithara tse 3.
- Li-piston tsa aluminium li sirelelitsoe ka ho roala ha graphite.
- Likamore tse tukang li fumaneha ka har'a hlooho ea silinda, li bōpehile ka tente.
- Ho kenya ente e tobileng ea GDI (liphetoho tsa morao-rao tsa 6G72).
E matla ka ho fetisisa liphetohong tsa enjine ea 6G72 e ne e le mofuta oa turbo, o hlahisang 320 hp. Ka. Enjene e joalo e ile ea kenngoa ho Dodge Steel le Mitsubishi 3000 GT.
Hoa hlokomeleha hore pele ho qaleha ha lelapa la Cyclon, MMC e ne e khotsofetse ka botlalo ka ba bane ba marang-rang. Empa ka ho fihla ha li-SUV tse kholo, li-minivans le li-crossovers, ho na le tlhokahalo ea lihlopha tse matla haholoanyane. Ka hona, "tse 'nè" tsa "line" li ile tsa nkeloa sebaka ke "tse tšeletseng" tse bōpehileng joaloka V,' me liphetoho tse ling li ile tsa fumana li-camshaft tse peli le hlooho ea cylinder.
Moetsi o tsepamisitse maikutlo ho tse latelang nakong ea ho etsa li-motors tse ncha:
- ho leka ho eketsa matla, ho sebelisa mofuta oa turbocharged;
- ho leka ho fokotsa tšebeliso ea mafura, o ile a ntlafatsa tsamaiso ea valve.
Tšebeliso ea oli 6G72 e nyolohetse ho 800 g/1000 km ka lebaka la likarolo tse ling tsa tekheniki. Phetoho e ka itlhalosa ka mor'a hore ho matha 150-200 sekete.
Litsebi tse ling li hlalosa mefuta e mengata ea liphetoho tsa 6G72 ka monyetla oa matla a fapaneng a enjene. Kahoo, e ka hlahisa, ho itšetlehile ka phetolelo: 141-225 hp. Ka. (phetoho e bonolo ka li-valve tse 12 kapa 24); 215-240 l. Ka. (phetolelo e nang le ente e tobileng ea mafura); 280-324 l. Ka. (mofuta oa turbocharged). Litekanyetso tsa torque le tsona lia fapana: bakeng sa liphetolelo tse tloaelehileng tsa sepakapaka - 232-304 Nm, bakeng sa li-turbocharged - 415-427 Nm.
Ha e le tšebeliso ea li-camshafts tse peli: ho sa tsotellehe hore moqapi oa 24-valve o hlahile pejana, morero oa DOHC o ne o sebelisoa feela ho tloha qalong ea 90s ea lekholo la ho qetela la lilemo. Liphetolelo tsa pejana tsa 24-valve tsa enjene li ne li e-na le camshaft e le 'ngoe feela. Ba bang ba bona ba sebelisitse ente e tobileng ea GDI, e ileng ea eketsa tekanyo ea khatello.
Mofuta oa turbocharged oa 6G72 o na le compressor ea MHI TD04-09B. Li-coolers tse peli li kopantsoe le eona, kaha intercooler e le 'ngoe ha e khone ho fana ka moea o hlokahalang bakeng sa li-cylinders tse tšeletseng. Mofuteng o mocha oa enjene ea 6G72, ho sebelisitsoe lipiston tse ntlafalitsoeng, li-coolers tsa oli, li-nozzles le li-sensor.
Ho khahlisang, bakeng sa 'maraka oa Europe, lienjineri tsa 6G72 turbo li ile tsa tla le TD04-13G compressor. Khetho ena e ile ea lumella setsi sa motlakase ho fihlela matla a 286 a etsang dilitara tse. Ka. ka khatello e matla ea 0,5 bar.
