ILexus LM300h isuselwe kuToyota Alphard minivan. I-MC II yathathwa njengenkundla. Ukubukeka kwemoto kube nezinguquko eziphawulekayo. Ekwakhiweni kwangaphambili kwengezwe:
- i-grille entsha;
- i-optics ebuyekeziwe;
- ukuhlobisa kwe-chrome.
I-wheelbase yemoto ingu-3000 mm. Ngenxa yezinto eziyindilinga zomklamo wangaphandle, iLexus LM300h ibonakale iyinde ngo-65 mm kuneToyota Alphard. Ama-absorbers okwethuka aphinde ahlelwa emotweni, kodwa umenzi akazange ahambe ukuze aphinde asebenze kabusha ukumiswa nokulungiswa kweziphethu zomoya. Ukugoba okungezansi kubukeka kuthakazelisa futhi kukhumbuleka, kusondele ngokushelela kuma-arches amasondo angemuva. Imoto inomnyango ohinjisiwe ukuze kube lula kubagibeli abagibelayo.
Abaklami benze umsebenzi omuhle ekulungiseni kwangaphakathi. Emotweni, abagibeli abakhulu ngaphakathi kweveni elincane ngabagibeli abangemuva. Kunendathane yesikhala samahhala sabo. I-Lexus LM300h itholakala ngamaleveli amabili wokunquma:
- Ubuhle;
- Royal Edition.
Ukucushwa okuyisisekelo kwe-Elegance kunokucushwa kwezihlalo eziyisikhombisa ngokohlelo lwe-2 + 2 + 3. Inguqulo kanokusho yeRoyal Edition ifika nezihlalo ezine ezinezihlalo ezingu-2 + 2. Ekucushweni okucebile kukhona ingilazi ye-electrochromatic enesikrini esakhelwe ngaphakathi esingu-26-intshi. Izihlalo zomugqa wesibili zifakwe:
- ukushisisa;
- ukungena komoya;
- massage;
- izinguquko eziningi zikagesi zokwandisa induduzo;
- izinyawo ezihlehliswayo;
- isikrini sokuthinta ukuze ulawule yonke imisebenzi ye-multimedia nesevisi.
Injini ngaphansi kwe-hood Lexus LM300h
Iyunithi yamandla eyingxube ye-300AR-FXE ifakwe kuhood ye-Lexus LM2h minivan. Lena inguqulo encishisiwe ye-base 2AR motor. Injini yomlilo yangaphakathi isebenza kumjikelezo we-Atkinson. Isikhungo samandla sithole ukuthandwa ngenxa yokusebenza kwayo okuphezulu nokuthembeka okuhle kakhulu.
Iyunithi yamandla ye-2AR-FXE inebhulokhi yesilinda ye-aluminium. Imikhono inobuso obungaphandle obungalingani. Ifaka isandla ekushiseleni okuhlala isikhathi eside futhi ithuthukise ukuchithwa kokushisa. I-crankshaft itholakala ne-desaxage engu-10 mm, enciphisa umthwalo kupheya lomkhono we-parshen.
Idizayini yenjini inephampu kawoyela yohlobo lwe-cycloid. Ifakwe kukhava yeketango lesikhathi. Isihlungi sinomklamo ogoqekayo. Ngakho-ke, ukushintshwa ngezikhathi ezithile kuyadingeka kuphela kuma-cartridges ashintshwayo. Lokhu kunciphisa izindleko zokunakekela futhi kunciphisa ukungcoliswa kwemvelo.
2AR-FXE izinjini ifakwe Dual VVT-i variable valve timing. Ngenxa yalokhu, kube nokwenzeka ukuthuthukisa izici zemvelo namandla wesikhungo samandla. Iketango lomugqa owodwa lisetshenziselwa ukushayela isikhathi. Ine-lubrication ehlukile ene-nozzle ekhethekile.
I-manifold yokuthatha yenziwe ngepulasitiki. Inama-swirl flaps ngaphakathi. Bashintsha i-geometry yomqoqi. Ama-flap asheshisa ukugeleza komoya. Bayakwazi ukudala isiyaluyalu emakamelweni okusebenza.
Imininingwane yeyunithi yamandla
Iyunithi yamandla ye-2AR-FXE ayikwazi ukuziqhayisa ngama-dynamics avelele noma i-torque ephezulu. Lena yi-hybrid ejwayelekile yokunethezeka yemoto kanokusho. Ukushayela ugesi kuyamsiza emsebenzini wakhe. Ungakwazi ukujwayelana nezici zenjini yomlilo yangaphakathi etafuleni elingezansi.
| Ipharamitha | Okushoyo |

Inombolo yenjini ye-2AR-FXE itholakala ngqo esizeni esisilinda block. Itholakala ngezansi kwenjini. Ukumaka kutholakala eduze nendawo yokubeka i-gearbox. Ukuze ubuke inombolo, kunconywa ukusebenzisa isibuko sokuhlola.
Ukwethembeka kanye nobuthakathaka
Injini ye-2AR-FXE inokwethenjwa okuhle ngokuvamile. Ngesikhathi esifanayo, ukusetshenziswa kwayo ku-Lexus LM300h kunesikhathi esifushane kakhulu. Ngakho-ke, kunzima ukwahlulela ukuthi iyunithi yamandla izoziphatha kanjani kule modeli ethile yemoto. Isilinganiso sokwethembeka sisekelwe ngokungaqondile ekusetshenzisweni kwe-2AR-FXE kweminye imishini.
Idizayini yenjini inamapiston acwebezelayo anengxubevange yesiketi esingenalutho. Indandatho ephezulu yokucindezelwa ifakwe i-anodized futhi udebe lwayo lujiya ngomhwamuko wamakhemikhali ukuze kwakheke okokungagqoki. Lokhu kukuvumela ukuthi ukhulise insiza yeqembu le-cylinder-piston. Lapho uqaqa izinjini nge-mileage engaphezu kwezinkulungwane ezingama-250 km, ungabona ama-pistons esesimweni esihle kakhulu.
Iphuzu elibuthakathaka le-2AR-FXE yi-VVT-i couplings. Bavame ukudala umsindo ongaphandle ngesikhathi sokusebenza. Ama-couplings avame ukuba nokuvuza kwe-lubricant. Ukuxazulula inkinga ngokuvamile kuhambisana nenani lobunzima.
Ukugcinwa kwezimoto
Ukugcinwa kwezinjini ze-2AR-FXE kuphansi kakhulu. I-aluminium cylinder block yabo ayikho ngaphansi kwe-capital futhi ibhekwa njengento engasetshenziswa. Ngakho-ke, uma kwenzeka umonakalo omkhulu, kunconywa ukuthenga imoto yenkontileka. I-Lexus LM300h ine-mileage ephansi njengoba imoto isanda kudayiswa. Ngakho-ke, abanikazi bezimoto ezincane ngeke babhekane nesidingo sokulungisa injini ngokushesha.
Izinkinga ezincane nge-2AR-FXE motor akunzima kangako ukuzilungisa. Iyunithi yamandla ayinawo amaphutha edizayini abalulekile. Ubunzima buvela kuphela ngokucinga izingxenye ezisele. Izingxenye zokulungisa azithandwa kakhulu, ngoba injini ye-2AR-FXE ayizange ithole ukusatshalaliswa okuningi.
Ukuthengwa kwenjini yenkontileka
Ukuthola injini yenkontileka engu-2AR-FXE nge-Lexus LM300h cishe akunakwenzeka. Isizathu salokhu ukuthi iveni isanda kuqala ukukhiqizwa. Ngakho-ke, imoto ayizihlinzeki ngenxa yobusha bayo, ukutholakala kwayo okuphansi kanye nezindleko eziphakeme. Lapho kuthengiswa kulula ukuthola izinjini ze-2AR-FXE ezikhishwa ku-:
- Toyota Camry XV50;
- IToyota RAV4 XA40;
- I-Toyota Camry Hybrid;
- I-Lexus ES 300h XV60.
Intengo elinganiselwe yamayunithi wamandla we-2AR-FXE imayelana nama-ruble ayizinkulungwane ezingama-70. Kufanele kukhunjulwe ukuthi injini ayilungiseki. Ngakho-ke, kubalulekile ukunaka ukuxilongwa kokuqala. Akunakwenzeka ukubuyisela injini "ebulewe", ngakho-ke kunconywa ukudlula okunikezwayo kwama-ruble ayizinkulungwane ezingama-25-40.
