Mazda L3 injini
Zviri mukati
Iyo modhi inonzi L3 iine-cylinder injini yakagadzirwa uye inogadzirwa neMazda mota inofunganya. Motokari dzakashongedzerwa neinjini dzakadaro munguva kubva 2001 kusvika 2011.
Iyo L-kirasi mhuri yemayuniti injini yepakati-inotamisa iyo inogona kugara kubva 1,8 kusvika 2,5 malita. Ese injini dzemhando yepeturu dzakashongedzerwa nealuminium zvidhinha, izvo zvinozowedzerwa neakakanda simbi liner. Diesel injini sarudzo dzinoshandisa mabhuroko esimbi akakandwa ane misoro yealuminium pane block.

Mazda's L3 injini dzakasarudzwa katatu pazita reInjini Yegore. Vaive pakati pezvikamu gumi zvinotungamira pasi rose kubva 2006 kusvika 2008. Iyo Mazda L3 yakatevedzana injini inogadzirwawo neFord, iyo ine kodzero yekuita kudaro. Motokari iyi muAmerica inonzi Duratec. Mukuwedzera, hunyanzvi hweiyo injini yeMazda inoshandiswa neFord mukugadzira mota dzeEco Boost. Kusvikira munguva pfupi yapfuura, L3 kirasi injini dzine vhoriyamu 1,8 uye 2,0 litita akashandiswawo kugadzirira Mazda MX-5 motokari modhi. Chaizvoizvo, injini yechirongwa ichi yakaiswa pamotokari yeMazda 6.
Aya mayunitsi anomiririra chimiro cheDISI injini, zvinoreva kuvepo kwejekiseni rakananga uye spark plugs. Injini dzakawedzera simba, pamwe nekuchengetedza. L3 injini yakajairwa kusimuka 2,3 l, simba guru 122 kW (166 hp), torque yakakura 207 Nm/4000 min.-1, iyo inokubvumira kuti uwane yepamusoro-soro - 214 km / h. Aya mamodheru emayuniti ane turbocharger anonzi S-VT kana Sequential Valve Timing. Magasi ekupisa anopisa anotyaira turbocharger, iyo ine mablades maviri, kuita chiito. Iyo impeller inorukwa mu compressor housing nerubatsiro rwemagasi anosvika 100 min.-1.
Dynamics yeL3 injini
Iyo impeller shaft inotenderedza vane yechipiri, iyo inopomba mweya mucompressor, iyo inozopfuura nemukamuri yekupisa. Sezvo mweya unopfuura nemu compressor, inopisa zvakanyanya. Nokuda kwekutonhora kwayo, ma radiator anokosha anoshandiswa, basa iro rinowedzera simba rejini kusvika pakakwirira.
Uye zvakare, iyo L3 injini yakagadziridzwa zvine hunyanzvi pamusoro pemamwe mamodheru, nekuvandudzwa mune zvese dhizaini uye zvitsva zvinoshanda. Kudzorwa kwezvikamu zvekugovera gasi kwakagamuchira chimiro chitsva mumainjini aya. Iyo block, pamwe neiyo silinda musoro, inogadzirwa nealuminium yeinjini.
Pamusoro pezvo, shanduko dzemagadzirirwo dzakaitwa kuti dzideredze ruzha uye mazinga ekudengenyeka. Kuti uite izvi, mainjini aive akashongedzerwa nemabhanhire emakaseti ekuyeresa uye cheni dzakanyarara pakutyaira kwegasi rekugovera michina. Siketi refu yepiston yakaiswa pacylinder block. Iyo zvakare yakazadzikiswa neyakasanganiswa main bearing cap. Iyo crankshaft pulley inoshanda kune ese L3 injini. Iyo yakashongedzerwa ne torsional vibration damper, pamwe nekumiswa kwependulum.
Iyo yekubatsira bhandi bhandi contour yakareruka kuitira kuchengetedza zvirinani. Kune vese, bhandi rekutyaira rimwe chete rave kurongwa. The automatic tension inogadzirisa nzvimbo yebhanhire. Kugadziriswa kwezvikwata zvinogoneka kuburikidza negomba rakakosha pachivharo chepamberi chejini. Nenzira iyi, ratchet inogona kusunungurwa, maketani anogona kugadziriswa uye ruoko rune simba runogona kugadziriswa.
Iwo mana masilinda einjini yeL3 ari mumutsara mumwe uye akavharwa kubva pazasi neakakosha pallet inoumba crankcase. Iyo yekupedzisira inogona kuita sedhiza rekuzora uye kutonhora mafuta, yakakosha ruzivo rwekuwedzera kupfeka kuramba kwemota. Iyo L3 unit ine gumi nematanhatu mavharuvhu, mana mune imwe silinda. Nekubatsirwa kwema camshafts maviri ari pamusoro pejini, mavharuvhu anotanga kushanda.

Injini iyi ina-humburumbira, 16-vharuvhu ane simba 2,3 litres uye maviri pamusoro camshafts. Yakashongedzerwa ne turbocharged injini, umo jekiseni remafuta rinoitika zvakananga. Iyo unit yakashongedzerwa nemhepo intercooler, inobatidza uchishandisa coil pakenduru, pamwe neWarner-Hitachi K04 mhando turbine. Injini ine 263 hp. uye 380 torque pa5500 rpm. Iyo yakanyanya kumhanya injini isingazokuvadzi zvikamu zvayo ndeye 6700 rpm. Kuti umhanye injini, unoda mhando 98 peturu.
Customer Reviews
Sergey Vladimirovich, makore 31 okuberekwa, Mazda CX-7, L3-VDT injini: akatenga motokari itsva muna 2008. Ini ndinogutsikana neinjini, inoratidza zvakanakisa kutyaira mhedzisiro. Rwendo rwacho rwuri nyore uye rwakasununguka. Chinhu chimwe chete chakashata ndechekunyanya kushandiswa kwemafuta.
Anton Dmitrievich, ane makore 37, Mazda Antenza, 2-litre L3: injini yemotokari inokwana kuwana zvakanyanya kubva parwendo. Simba rinogovaniswa zvakaenzana mukati mese rev rev. Iyo mota inoita zvakanaka zvese panjanji uye mukupfuura.
