Galimoto imayikidwa kutali kwambiri ndi bumper kutsogolo kuti ipititse patsogolo kulemera kwa galimoto mpaka 48/52. Pofuna kuchepetsa pakati pa mphamvu yokoka, malo opangira magetsi adalandira makina owuma a sump lubrication.
Lexus LFA ndiye galimoto yabwino kwambiri ya aerodynamically. Mabowo onse mmenemo amapangidwa osati kukongola, koma zolinga zothandiza. Kotero, mwachitsanzo, malo otsika kwambiri amapangidwa pafupi ndi ma gratings pamene akuyendetsa pa liwiro lalikulu. Izi zimakuthandizani kuti mutenge kutentha kuchokera kuchipinda cha injini, kuziziritsanso injini yodzaza. Ma radiators ozizira amakhala kumbuyo kwa makina, zomwe zimawonjezera kulemera kwake.
Injini ya 1LR-GUE imatha kutsitsimuka kuchoka pakuchita ntchito mpaka ku redline mu 0.6s. Analogi tachometer sadzakhala ndi nthawi yoyang'ana kuzungulira kwa crankshaft chifukwa cha inertia ya dongosolo. Chifukwa chake, chophimba chamadzimadzi cha kristalo chimapangidwa mu dashboard, chomwe chimawonetsa ma dials osiyanasiyana ndi zidziwitso zina. Makinawa amagwiritsa ntchito tachometer ya digito, yomwe imatsimikizira mwachangu liwiro lenileni la crankshaft.
Mphamvu yamagetsi ili ndi malire apamwamba a chitetezo. Dry sump lubrication system imalepheretsa njala yamafuta pa liwiro lililonse komanso pamakona. Kukonzekera kwa injini kumachitika kwathunthu ndi dzanja ndi munthu m'modzi. Kupirira zolemetsa zazikulu mu 1LR-GUE zimagwiritsidwa ntchito:
- pisitoni zopeka;
- titaniyamu kugwirizana ndodo;
- manja a rocker wokutidwa ndi mwala;
- valavu titaniyamu;
- crankshaft yabodza.
Makhalidwe aukadaulo agawo lamagetsi 1LR-GUE
Injini ya 1LR-GUE ndiyopepuka komanso yolemetsa. Imalola Lexus LFA kuthamanga mpaka 100 km/h mu masekondi 3.7. Malo ofiira a injini ali pa 9000 rpm. Mapangidwe a injini yoyatsira mkati amapereka ma valve 10 osiyana siyana komanso mitundu yosiyanasiyana yolowera. Mafotokozedwe ena a injini angapezeke mu tebulo ili m'munsimu.

Nambala ya injini ili kutsogolo kwa chipika cha silinda. Ili pafupi ndi zosefera mafuta. Pafupi ndi cholembera pali nsanja yosonyeza kuti akatswiri a Yamaha Motor adatenga nawo gawo pakupanga gawo lamagetsi. Komanso, galimoto iliyonse mwa magalimoto 500 opangidwa ali ndi nambala yake siriyo.

Kudalirika kwa gawo lamagetsi kumakhudzidwa ndi mafuta owonjezera. Nambala yake ya octane iyenera kukhala osachepera 98. Apo ayi, detonation ikuwonekera. Imatha kuwononga gulu la silinda-pistoni, makamaka pansi pa katundu wambiri wotentha komanso wamakina.
Kukhazikika kwagalimoto
Injini ya 1LR-GUE ndi yamphamvu yokhayokha. Kukonzekera kwake sikungathe kuchitidwa pa malo ochitira utumiki wamba. Capital ndiyopanda funso. Zida zosinthira za ICE 1LR-GUE sizigulitsidwa.
Kupadera kwa kapangidwe ka 1LR-GUE kumachepetsa kusamalidwa kwake mpaka zero. Ngati ndi kotheka, sikutheka kupeza ma analogue a zida zosinthira mbadwa. Chifukwa chake, ndikofunikira kukonza nthawi yake komanso kugwiritsa ntchito zinthu zapamwamba zokha. Pankhaniyi, kukonza sikudzafunika posachedwa, chifukwa injiniyo ili ndi malire odalirika.

Mphamvu ya 1LR-GUE ndi injini yolakalaka mwachilengedwe. Komabe, sikutheka kugwiritsa ntchito turbine pa izo. Palibe mayankho okonzeka komanso zida za turbo za injini iyi zomwe zikugulitsidwa. Chifukwa chake, kuyesa kulikonse kozama kapena kongoyerekeza kungayambitse kuwonongeka kwakukulu kwa injini yoyaka mkati, osati kuwonjezera mphamvu zake.
