Moetso o bitsoang L3 ke enjene ea lisilindara tse 'ne e ntlafalitsoeng le ho hlahisoa ke ho ameha ha koloi ea Mazda. Likoloi li ne li e-na le lienjineri tse joalo ho tloha ka 2001 ho ea ho 2011.
Lelapa la L-class la diyuniti ke enjene ea phalliso e mahareng e ka nkang lilithara tse 1,8 ho isa ho tse 2,5. Lienjine tsohle tsa mofuta oa peterole li na le li-block tsa aluminium, tseo le tsona li tlatsitsoeng ke lithapo tsa tšepe tse entsoeng ka tšepe. Likhetho tsa enjene ea diesel li sebelisa li-block tsa tšepe tse nang le lihlooho tsa aluminium holim'a boloko.

Lienjine tsa Mazda tsa L3 li khethiloe ka makhetlo a mararo bakeng sa sehlooho sa Engine ea Selemo. E ne e le tse ling tsa lihlopha tse leshome tse etelletseng pele lefatšeng ho tloha 2006 ho isa 2008. Letoto la lienjine tsa Mazda L3 le boetse le hlahisoa ke Ford, e nang le tokelo ea ho etsa joalo. Enjene ena Amerika e bitsoa Duratec. Ho phaella moo, likarolo tsa theknoloji tsa "Mazda" li sebelisoa ke Ford ha ho etsoa likoloi tsa Eco Boost. Ho fihlela haufinyane tjena, lienjineri tsa sehlopha sa L3 tse nang le boholo ba lilithara tse 1,8 le 2,0 li ne li boetse li sebelisetsoa ho hlomella mofuta oa koloi oa Mazda MX-5. Ha e le hantle, lienjineri tsa morero ona li ne li kentsoe likoloing tsa Mazda 6.
Liyuniti tsena li emela sebopeho sa lienjineri tsa DISI, ho bolelang boteng ba ente e tobileng le li-spark plugs. Li-engines li na le matla a eketsehileng, hammoho le ho boloka. Enjene ea L3 e tloaelehileng ea ho falla 2,3 l, matla a phahameng a 122 kW (166 hp), torque e phahameng 207 Nm / 4000 min-1, e leng se u lumellang hore u fumane lebelo le phahameng ka ho fetisisa - 214 km / h. Mefuta ena ea li-unit e na le li-turbocharger tse bitsoang S-VT kapa Sequential Valve Timing. Likhase tse cheleng tsa mosi li khanna turbocharger, e nang le likhaba tse peli, hore e kene tšebetsong. Mokelikeli o ohloa ka har'a ntlo ea compressor ka thuso ea likhase tse fihlang ho 100 min.-1.
Matla a lienjineri tsa L3
The impeller shaft e ohla vane ea bobeli, e pompa moea ka har'a compressor, e ntan'o feta ka kamoreng ea mollo. Ha moea o feta har'a kompressor, o chesa haholo. Bakeng sa ho pholile ha eona, ho sebelisoa li-radiator tse khethehileng, mosebetsi oa tsona o matlafatsang matla a enjene ho ea holimo.
Ntle le moo, enjene ea L3 e ntlafalitsoe ka botekgeniki ho feta mefuta e meng, ka ntlafatso ea moralo le likarolo tse ncha tse sebetsang. Taolo ea mekhahlelo ea kabo ea khase e fumane sebopeho se secha lienjineng tsena. Sebaka, hammoho le hlooho ea silinda, li entsoe ka aluminium bakeng sa lienjineri.
Ho feta moo, ho ile ha etsoa liphetoho tsa moralo ho fokotsa maemo a lerata le ho sisinyeha. Ho etsa sena, lienjine li ne li e-na le li-block tsa cassette tse leka-lekaneng le liketane tse khutsitseng holim'a mochini oa ho tsamaisa khase. Sesepa se selelele sa piston se ile sa behoa holim'a cylinder block. E ne e boetse e tlatsitsoe ke sekoahelo se ka sehloohong se kopantsoeng. Pulley ea crankshaft e sebetsa ho lienjine tsohle tsa L3. E na le damper ea torsional vibration, hammoho le ho emisoa ha pendulum.
Mohaho o thusang oa lebanta la koloi o nolofalitsoe bakeng sa ho boloka hantle. Bakeng sa bona kaofela, ho na le lebanta le le leng feela la koloi le lokiselitsoeng. Khatello ea boiketsetso e lokisa boemo ba lebanta. Tlhokomelo ea diyuniti e ka khoneha ka lesoba le khethehileng sekoahelong se ka pele sa enjene. Ka tsela ena, ratchet e ka lokolloa, liketane li ka fetoloa 'me letsoho le thata le ka lokisoa.
Li-cylinders tse 'nè tsa enjene ea L3 li fumaneha moleng o le mong' me li koetsoe ho tloha ka tlase ke pallet e khethehileng e etsang crankcase. Ea morao-rao e ka sebetsa e le sebaka sa polokelo ea oli ea ho tlotsa le ho pholisa, lintlha tsa bohlokoa bakeng sa ho eketsa ho se sebetse ha enjene. Sehlopha sa L3 se na le li-valve tse leshome le metso e tšeletseng, tse 'nè ka silindara e le' ngoe. Ka thuso ea li-camshaft tse peli tse ka holimo ho enjene, li-valve li qala ho sebetsa.
