Mazda e ntse e tsoela pele ka nts'etsopele ea theknoloji ea Skyactiv ka li-block tsa peterole le disele. Fumana yuniti ea morao-rao ea 1.5 Skyactiv D e tla qala ho Mazda 2 e latelang.
Kamora block ea 2.2 Skyactiv D, joale ho na le moena e monyane, 1.5 Skyactiv D, e nang le qalo ea eona e tšoailoeng ka bokamoso ba Mazda 2.
Enjene ena e ncha e tsoang ho Mazda e nang le theknoloji ea Skyactiv e se e ntse e kopana le litekanyetso tse thata tsa EURO 6, 'me e etsa joalo ntle le sistimi efe kapa efe ea catalysis. Empa ho fihlela sephetho sena, Mazda e ile ea tobana le mathata a 'maloa a fokotsang bokhoni ba mochini oa Diesel.
Leha ho le joalo, sephetho se fumanoeng, ka ho sebelisa mochine oa geometry turbocharger le sensor e kopantsoeng ea ho potoloha, hammoho le intercooler e pholileng ka metsi, e khotsofatsa ka ho feletseng letšoao la Japane. Ea bobeli, e tla ntlafatsa katleho le karabelo ea 1.5 Diesel block. Mazda e lumela hore e tla ba le enjene ea diesel e sebelisoang tlase haholo sehlopheng sa eona.
Sebaka sa 1.5 Skyactiv D se itlhahisa ka ho falla ha 1497cc le 105 horsepower ho 4000rpm, torque e phahameng ea 250Nm e hlaha kapele ho 1500rpm mme e lula e le teng ho fihlela haufi le 2500rpm, kaofela ka tlhahiso ea CO₂ ea 90g/km feela.
Empa ho finyella litekanyetso tsena, hase ntho e 'ngoe le e' ngoe e neng e le monate, 'me Mazda e tobane le mathata a mangata a theknoloji. Mathata ao ho ea ka letšoao a ileng a hlōloa, ka ho sebelisa mekhoa ea morao-rao ea theknoloji. Empa ha re eeng ka likarolo, ka sepheo sa ho manolla liqholotso tsohle tseo Mazda e li hlotseng ho nts'etsapele enjene ena ea 1.5 Skyactiv D.
Ho ne ho ka khoneha joang ho hlōla litekanyetso tse boima tsa tikoloho ntle le tlhokahalo ea phekolo ea matla?
Li-block tsa diesel hangata li sebetsa ka litekanyetso tsa khatello, tse phahameng haholo ho feta li-block tsa peterole. Sena se bakoa ke ho khetheha ha mollo oa diesel, o phatlohang ka likhatello tse phahameng 'me ha o phatlohe joaloka peterole, empa o tšoara mollo.
Taba ena e ba bothata ka ho khetheha, kaha ka lebaka la litekanyetso tse phahameng tsa khatello, ha piston e le TDC ea eona (top dead center), ho chesa ho atisa ho etsahala pele ho motsoako o feletseng le o lekanang pakeng tsa moea le mafura, ho fella ka ho thehoa ha likhase tsa NOx le likaroloana tse silafatsang. Ho lieha ho kenya ente ea mafura, ha ho ntse ho thusa ka mocheso le khatello, ho fella ka moruo o mpe haholo 'me kahoo tšebeliso e phahameng.
Mazda, ka ho tseba ka mathata ana, leha ho le joalo e ile ea etsa qeto ea ho becha ka ho fokotsa tekanyo ea compression ea li-block tsa Diesel Skyactiv, ka compression ratios ea 14.0: 1 - boleng bo hlakileng bo tlase bakeng sa boloko ba diesel, kaha karolelano e ka bang 16.0: 1. Ho sebelisa tharollo ena, ho sebelisa li-piston tse tsoang likamoreng tse itseng tse tukang, ho ne ho ka khoneha ho fokotsa mocheso le khatello ho PMS ea li-cylinders, kahoo ho ntlafatsa motsoako.
Ha bothata bona bo rarollotsoe, bothata ba moruo oa mafura bo ne bo ntse bo lokela ho rarolloa, kahoo Mazda e ile ea sebelisa boselamose ba elektronike. Ka mantsoe a mang, limmapa tsa ente tse nang le li-algorithms tse rarahaneng tse khonang ho etsa motsoako oa pele o ntlafalitsoeng, ka bolokong bo nang le sekhahla se tlase sa khatello. Ho phaella liphellong tse molemo tsa ho tuka, ho fokotseha ha tekanyo ea khatello ho entse hore ho khonehe ho fokotsa boima ba thibela, kaha e tlas'a khatello e fokolang ea ka hare, kahoo e ntlafatsa tšebeliso le lebelo la enjene ea ho arabela.
Mazda e ile ea rarolla bothata ba ho qala ho batang le ho hotetsa ha koloi e chesang ka tekanyo e tlase ea khatello?
Tsena e ne e le mathata a mang a mabeli a bakileng karo-karolelano e tlase ea khatello ea block. Ka tekanyo e tlase ea khatello, ho ba thata haholo ho haha khatello le mocheso o lekaneng hore mafura a ka hotetsa. Ka lehlakoreng le leng, ha block e chesa, tekanyo e tlaase ea compression e etsa hore ho be thata hore ECU e laole.
E ne e le ka lebaka la litaba tsena moo Mazda a ileng a etsa qeto ea ho kenyelletsa 1.5 Skyactiv D block, liente tsa morao-rao tsa Piezo tse nang le li-nozzles tse 12, tse lumellang mefuta e sa tšoaneng ea ente le maemo a ts'ebetso ka nako e khutšoanyane haholo, ho khona ho etsa liente tse 9 ka nako e le 'ngoe. cycle , ho lumella ho laola mahloriso a motsoako, ho rarolla bothata ba ho qala ho bata.
Ho phaella ho mekhoa e 3 ea motheo ea ente (ente ea pele, ente e kholo le ka mor'a ho entoa) liente tsena tsa Piezo li ka etsa mekhoa e mengata e fapaneng ho latela maemo a sepakapaka le boima ba enjene.
Ho ile ha rarolloa ka mokhoa o ikemetseng, ka tšebeliso ea nako e fapaneng ea li-valve.
