Saka, semuenzaniso, muparadzi wekumashure akawana mukana wekuchinja kona yayo. Izvi zvinokubvumira kuti uwedzere downforce pamusana wekumashure wemotokari. Mainjiniya vakatarisa pane zvidiki zvidiki, saka kunyangwe nati yega yega inogadzirwa kuti iite yakavimbika uye inotaridzika zvakanaka.
Vagadziri vakanakisisa venyika vakashanda mukati memotokari. Zvigaro zveOrthopedic zvine lateral tsigiro inogadzirisa zvakachengeteka mutyairi nemutyairi. Muchina uyu unoshandisa Remote Touch tekinoroji, inotsiva komputa mbeva. Nerubatsiro rwayo, zviri nyore kubata ese anonyaradza sarudzo mune kabhini. Kupedza Lexus LFA inogadzirwa uchishandisa kabhoni faibha, dehwe, yakakwirira-inopenya simbi uye Alcantara.

Lexus LFA ndiyo yakanyanya aerodynamically yakakwana mota. Makomba ose mairi haana kugadzirirwa kunaka, asi nokuda kwezvinangwa zvinoshanda. Saka, semuenzaniso, nzvimbo yakaderera yekumanikidza inoumbwa padhuze negirating kana uchityaira nekumhanya kukuru. Izvi zvinokutendera kuti utore kupisa kubva mukamuri yeinjini, uchiwedzera kutonhora injini yakatakura. Kutonhorera radiators ari kumashure kwemuchina, iyo inovandudza uremu hwayo kugovera.
Iyo 1LR-GUE injini inokwanisa kusimuka kubva pakusaita basa kuenda kune redline mumasekonzi 0.6. Iyo analog tachometer haizove nenguva yekutevera kutenderera kwe crankshaft nekuda kweiyo inertia yehurongwa. Naizvozvo, mvura yekristaro skrini inovakwa mudhibhodhi, iyo inoratidza akasiyana dials uye rumwe ruzivo. Muchina uyu unoshandisa dhijitari discrete tachometer, iyo inosarudza zvisina kunanga kumhanya chaiko kwe crankshaft.
Simba remagetsi rine muganhu wepamusoro wekuchengeteka. Iyo yakaoma sump lubrication system inodzivirira nzara yemafuta chero kumhanya uye mumakona. Kuungana kwemota kunoitika zvachose neruoko uye nemunhu mumwe. Kumira mitoro yakakosha mu1LR-GUE inoshandiswa:
- pistons dzakagadzirwa;
- titanium inobatanidza tsvimbo;
- maoko e rocker akavharidzirwa neflint;

Nhamba yeinjini iri kumberi kwecylinder block. Inowanikwa pedyo nemasefa emafuta. Padivi pekumaka pane chikuva chinoratidza kuti Yamaha Motor nyanzvi dzakatora chikamu mukuvandudza kwesimba remagetsi. Uyezve, motokari imwe neimwe kubva pa500 motokari inogadzirwa ine nhamba yayo ye serial.
Kuvimbika uye utera
Iyo Lexus LFA injini inokwanisa kusanganisa mutambo, umbozha uye kuvimbika. Kuedzwa kwemayuniti emagetsi kwakatora makore angangoita gumi. Kugadzirwa kwenguva refu kwakaita kuti zvibvirire kudzivirira "zvirwere zvehuduku" zvemota. ICE inonzwisisa kutevedzera mitemo yekuchengetedza.
Kuvimbika kwechikamu chemagetsi kunokanganisa nekuwedzera peturu. Nhamba yaro ye octane inofanira kunge iine 98. Zvikasadaro, detonation inooneka. Inokwanisa kuparadza boka re-cylinder-piston, kunyanya pasi pepamusoro pekushisa uye mechanical mitoro.
Motor kuchengetedza
Iyo 1LR-GUE injini ndeye yakasarudzika powertrain. Kugadziriswa kwayo hakugone kuitwa pane yakajairika service station. Capital haisi mubvunzo. Zvikamu zvakasiiwa zveICE 1LR-GUE hazvina kutengeswa.
Iyo yakasarudzika yeiyo 1LR-GUE dhizaini inoderedza kuchengetedza kwayo kusvika zero. Kana zvichidikanwa, hazvigoneke kuwana analogues ezvakaberekerwa zvisara. Naizvozvo, zvakakosha kuita kuchengetedza nenguva uye kushandisa chete zvemhando yepamusoro zvigadzirwa.

Iyo 1LR-GUE yemagetsi unit injini yakasikwa inoshuvira. Nekudaro, hazvizogoneke kushandisa turbine pairi. Iko hakuna yakagadzirira-yakagadzirwa mhinduro uye turbo kits yeinjini iyi iri kutengeswa. Naizvozvo, chero kuedza kwakadzika kana kwepamusoro kwemazuva ano kunogona kutungamirira mukukuvadza kwakakomba kune injini inopisa mukati, uye kwete kuwedzera kwesimba rayo.
