Mazda L3 injini
Zamkatimu
Lachitsanzo lotchedwa L3 ndi injini zinayi yamphamvu yopangidwa ndi kupangidwa ndi nkhawa galimoto Mazda. Magalimoto anali okonzeka ndi injini zimenezi nthawi kuyambira 2001 mpaka 2011.
Banja la L-class of units ndi injini yosamuka yomwe imatha kutenga malita 1,8 mpaka 2,5. Ma injini onse amtundu wa petulo amakhala ndi midadada ya aluminiyamu, yomwe imathandizidwanso ndi zitsulo zotayira. Zosankha za injini ya dizilo zimagwiritsa ntchito midadada yachitsulo yokhala ndi mitu ya aluminiyamu pa block.

Ma injini a L3 a Mazda adasankhidwa katatu pamutu wa Engine of the Year. Iwo anali m'gulu la magawo khumi otsogola padziko lonse lapansi kuyambira 2006 mpaka 2008. Ma injini a Mazda L3 amapangidwanso ndi Ford, omwe ali ndi ufulu wochita izi. Motor iyi ku America imatchedwa Duratec. Komanso, mbali luso la injini "Mazda" ntchito "Ford" kupanga magalimoto Eco Boost. Mpaka posachedwapa, injini za kalasi L3 ndi buku la 1,8 ndi malita 2,0 zinagwiritsidwanso ntchito popanga chitsanzo cha galimoto ya Mazda MX-5. Kwenikweni, injini za dongosolo ili anaikidwa pa Mazda 6 magalimoto.
Magawo awa akuyimira mawonekedwe a injini za DISI, zomwe zikutanthauza kukhalapo kwa jakisoni wachindunji ndi ma spark plugs. Ma injini ali ndi mphamvu zowonjezera, komanso kusunga. L3 injini muyezo kusamutsidwa 2,3 L, mphamvu pazipita 122 kW (166 hp), makokedwe pazipita 207 Nm/4000 min-1, zomwe zimakupatsani mwayi wothamanga kwambiri - 214 km / h. Mitundu iyi yamayunitsi ili ndi ma turbocharger otchedwa S-VT kapena Sequential Valve Timing. Mipweya yopsereza yowotcha imayendetsa turbocharger, yomwe imakhala ndi masamba awiri, kuti igwire ntchito. Cholowacho chimawotedwa mu nyumba ya kompresa mothandizidwa ndi mpweya wofikira 100 min.-1.
Mphamvu zama injini a L3
Mphepete mwa nthitiyo imazungulira chigawo chachiwiri, chomwe chimapopera mpweya mu kompresa, yomwe imadutsa mu chipinda choyaka moto. Mpweya ukadutsa mu kompresa, kumatentha kwambiri. Kwa kuziziritsa kwake, ma radiator apadera amagwiritsidwa ntchito, ntchito yomwe imathandizira mphamvu ya injini mpaka pazipita.
Kuphatikiza apo, injini ya L3 yasinthidwa mwaukadaulo kuposa mitundu ina, ndikuwongolera pamapangidwe ndi zida zatsopano zogwirira ntchito. Ulamuliro wa magawo ogawa gasi walandira mawonekedwe atsopano mu injini izi. Chidacho, komanso mutu wa silinda, amapangidwa ndi aluminiyumu yamainjini.
Kuonjezera apo, kusintha kwapangidwe kunapangidwa kuti kuchepetsa phokoso ndi kugwedezeka. Kuti achite izi, ma injiniwo anali ndi midadada yolumikizira makaseti ndi maunyolo opanda phokoso pagalimoto yamakina ogawa gasi. Siketi yayitali ya pisitoni idayikidwa pa block ya silinda. Idathandizidwanso ndi kapu yayikulu yophatikizika. Pulley ya crankshaft imagwira ntchito pamainjini onse a L3. Ili ndi damper ya torsional vibration, komanso kuyimitsidwa kwa pendulum.
Wothandizira lamba woyendetsa wasinthidwa kuti usamalike bwino. Kwa onsewa, lamba umodzi wokha woyendetsa tsopano wakonzedwa. Kuthamanga kwadzidzidzi kumasintha malo a lamba. Kukonza mayunitsi n'zotheka kudzera mu dzenje lapadera pa chivundikiro kutsogolo kwa injini. Mwanjira imeneyi, ratchet imatha kumasulidwa, maunyolo amatha kusinthidwa ndipo mkono wovutitsa ukhoza kukhazikitsidwa.
Masilinda anayi a injini ya L3 ali pamzere umodzi ndipo amatsekedwa kuchokera pansi ndi phale lapadera lomwe limapanga crankcase. Yotsirizirayi imatha kukhala ngati nkhokwe yosungiramo mafuta opaka ndi kuziziritsa, mfundo yofunika kwambiri pakuwonjezera kukana kwa injini. Chigawo cha L3 chili ndi ma valve khumi ndi asanu ndi limodzi, anayi mu silinda imodzi. Mothandizidwa ndi ma camshafts awiri omwe ali pamwamba pa injini, ma valve amayamba kugwira ntchito.
Zinthu za injini ndi ntchito zawo
| The actuator kusintha nthawi ya valve | Amasintha mosalekeza kutulutsa kwa camshaft ndi nthawi ya crankshaft kumapeto kwa camshaft yolowera pogwiritsa ntchito hydraulic pressure kuchokera ku valve control valve (OCV) |
| Valve yowongolera mafuta | Kulamulidwa ndi chizindikiro chamagetsi kuchokera ku PCM. Amasintha ma hydraulic oil channels a variable valve timing actuator |
| Crankshaft udindo kachipangizo | Imatumiza chizindikiro cha liwiro la injini ku PCM |
| Camshaft udindo kachipangizo | Amapereka chizindikiritso cha silinda ku PCM |
| Tsegulani RSM | Imawongolera valavu yowongolera mafuta (OCV) kuti ipereke nthawi yabwino yotsegulira kapena kutseka malinga ndi momwe injini imagwirira ntchito. |
Injiniyo imadzazidwa ndi mpope wamafuta, womwe umayikidwa kumapeto kwa sump. Mafuta amapezeka kudzera munjira, komanso mabowo omwe amatsogolera madzimadzi kupita kumayendedwe a crankshaft. Choncho mafutawo amafika ku camshaft ndi m'masilinda. Kupereka mafuta kumachitika pogwiritsa ntchito makina apakompyuta omwe amagwira ntchito bwino, omwe safunikira kuthandizidwa.
Mafuta omwe akulimbikitsidwa kugwiritsa ntchito:
- API kalasi SJ ACBA A1 kapena A3 ndi mamasukidwe akayendedwe 52-30;
- API kalasi SL ILSAC GF-3 ndi mamasukidwe akayendedwe a 5W-20;
- API giredi SG, SH, SJ, SL ILSAC GF-2, GF-3 yokhala ndi mamasukidwe akayendedwe 40, 30, 20, 20W-20, 10W-30, 10W-40, 10W-50, 20W-40, 15W-40, 20W -50, 15W-50, 5W-20, 5W-30.
Kusintha kwa L3-VDT
injini ndi yamphamvu zinayi, 16 vavu ndi mphamvu ya malita 2,3 ndi camshafts awiri pamwamba. Okonzeka ndi turbocharged injini, imene jekeseni mafuta kumachitika mwachindunji. Chipangizocho chili ndi cholumikizira mpweya, choyatsira pogwiritsa ntchito koyilo pa kandulo, komanso makina opangira makina a Warner-Hitachi K04. Injini ndi 263 hp. ndi 380 torque pa 5500 rpm. Kuthamanga kwa injini komwe sikungawononge zigawo zake ndi 6700 rpm. Kuti muyendetse injini, muyenera mtundu 98 mafuta.
Kuwonetsa kwa Wotsatsa
SERGEY Vladimirovich, zaka 31, Mazda CX-7, L3-VDT injini: anagula galimoto latsopano mu 2008. Ndine wokhutira ndi injini, ikuwonetsa zotsatira zabwino kwambiri zoyendetsa. Ulendowu ndi wosavuta komanso womasuka. Choyipa chokha ndicho kugwiritsa ntchito mafuta ambiri.
Anton Dmitrievich, zaka 37, Mazda Antenza, 2-lita L3: injini ya galimoto ndi yokwanira kuti apindule kwambiri paulendo. Mphamvu zimagawidwa mofanana pamtundu wonse wa rev. Galimoto imachita bwino panjira komanso pakudutsa.
