Tlhaloso: Двигатель Mitsubishi 3B20
Tse ka hare
Enjene ea koloi ea Mitsubishi 3B20 e ekelitse lelapa la lienjineri tse tharo tsa li-cylinder tse hlahisoang bakeng sa likoloi tsa tšepe tsa alloy kei.
Moetsong ona oa enjene, ho ile ha sebelisoa theknoloji e 'maloa e ncha, e ileng ea etsa hore ho khonehe, ha ho ntse ho fokotsa boholo ba yuniti, ho eketsa matla a eona le matšoao a mang a tekheniki.
Mabapi le histori ea tsoalo ea enjene
Enjene ea pele e joalo e ile ea hlahisoa ka 2005 ke k'hamphani ea Japane Mizushima Kurashiki, seterekeng sa Okayama.
Phetolelo ea pele ea enjene e entsoe pejana - ka 2003. Ke hona moo ho ileng ha sebelisoa Smart Idling system (smart idling), e timang enjene ka bo eona ha koloi e eme. Enjene e qala hape nakong ea metsotsoana e 0,2.
Ka mohlala ona oa enjene, k'hamphani e pakile hore ho ka khoneha ho finyella 3-litha e le nngwe (kapa ho feta) tšebeliso ea mafura.
Ha ho bapisoa: ba pele ho yuniti ea Mitsubishi 3B20, lienjineri tsa likoloi tse nyane li ne li sebelisa peterole ka makhetlo a 2-2,5.
Kei koloi ke eng? Sebaka sa enjene ka koloing
Enjene e ne e etselitsoe likoloi tse nyane tsa sehlopha sa likoloi tsa Kei, tse neng li reretsoe ho lokolloa selemo hamorao, ka 2006.
Kei-cars, kapa keijidosha, ke likoloi tse bobebe. Ke kopa o seke oa ferekanya le likoloi. E leng, e nyenyane, e bobebe. Ba ne ba hloka enjene e bobebe. Ka hona, bahlahisi ba fokolitse litekanyo tsa eona (bolelele ke 191 mm, bolelele - 286 mm).
Li-cylinder block le hlooho li ne li lahleloa ho tloha aluminium, e leng se entseng hore ho khonehe ho fokotsa boima ba eona ka 3% ha ho bapisoa le pele ho eona, enjene ea Mitsubishi 8G20. Enjene ea 3B20 e khanna ka morao, e boima ba 67 kg.
Sesebelisoa sa enjine ea Mitsubishi 3B20
Mola o le mong oa cylinder block le cylinder head (cylinder head) moleng ona oa ICE li entsoe ka li-alloys tsa aluminium. Mochine oa phepelo ea khase, o nang le li-camshaft tse peli le li-valve tse 12 (4 bakeng sa silinda e 'ngoe le e' ngoe) o hloohong ea BC.
Mochine o fetohang o sebelisa theknoloji ea MIVEC. Kgutsufatso ena e emetse Mitsubishi Innovative Valve timing Electronic Control system, e fetolelang puong ya Serussia ka mokgwa o latelang: tsamaiso ya elektroniki ya ho laola nako (ho hokahanya) ya mochini wa valve o sebedisang theknoloji ya Mitsubishi ya popontshwa. Theknoloji ea MIVEC ka lebelo le tlase:
- E eketsa botsitso ba ho tuka ka ho fokotsa phetisetso ea khase e tsoang ka hare;
- E tsitsisa mollo ka ho potlakisa spray;
- E fokotsa likhohlano ka ho phahamisa li-valve tse tlase.
Ka hona, ka lebelo le tlaase, phapang ea ho bula li-valve e laola le ho etsa hore ho chesa ha motsoako kamehla, ho eketsa nako ea matla.
Ka lebelo le phahameng, enjene e fumana monyetla oa ho hema ka matla a feletseng, ka lebaka la nako e eketsehileng le bophahamo ba phahamiso ea valve. Ho kenngoa ha motsoako oa mafura-moea le likhase tsa ho qeta lia eketseha. Ente ea mafura e laoloa ke sistimi ea elektroniki ea ECI-MULTI.
Ka kakaretso, lintlha tsena kaofela li ama keketseho ea matla, ho fokotsa tšebeliso ea mafura le ho fokotsa ho ntšoa ha lintho tse chefo sepakapakeng.
