Varidzi vemotokari havafariri izvi zvakanyanya, kunyanya tichifunga kuti masimba haaenderane nehuwandu hwemagetsi emagetsi zvachose. Naizvozvo, Lexus HS250h ine 2AZ-FXE inonyanya kukodzera kuyera kutyaira kweguta, uko inobata chinyararire uye zvinyoro.
Injini ye2AZ-FXE ine aluminium cylinder block. Sleeve dzesimbi dzakakandwa dzakabatanidzwa muzvinyorwa. Vane nzvimbo isina kuenzana yekunze, iyo inovimbisa kugadzirisa kwavo kwakasimba uye inovandudza kupisa kupisa. Pombi yemafuta yetrochoid inoiswa mukrankcase. Inotungamirirwa neketani yakawedzerwa, iyo inokonzera kuderera kwekuvimbika kwechikwata chemagetsi uye inowedzera nhamba yezvikamu zvinofamba.
Imwe pfungwa isina kusimba mukugadzirwa kwemota ndiyo magiya eiyo bancing mechanism. Izvo zvakagadzirwa ne polymer material. Izvi zvakawedzera kunyaradza uye kuderedzwa kweinjini ruzha, asi zvakakonzera kukanganisa kazhinji. Magiya epolymer anopera nekukurumidza uye injini inorasikirwa nekugona kwayo.
Zvinyorwa zvemagetsi emagetsi
Injini ye2AZ-FXE ine mapistoni akareruka akaiswa alloy, mapini anoyangarara uye anti-friction polymer coating. The forged crankshaft ine offset hukama nemutsara wemasanhu emasilinda.

Iyo injini nhamba ye2AZ-FXE inowanikwa zvakananga pachikuva pane cylinder block. Nzvimbo yayo inoratidzwa schematically mumufananidzo uri pazasi. Tsanangudzo dzeguruva, tsvina uye ngura zvinogona kuomesa kuverenga kwenhamba. Kuti uvachenese, zvinokurudzirwa kushandisa brashi yesimbi, machira.
Kuvimbika uye utera
Iyo 2AZ-FXE injini haigone kunzi yakavimbika. Iine huwandu hwekukanganisa kwekugadzira izvo zvakakonzera matambudziko emhando dzakasiyana dzekuomarara. Vanenge vese varidzi vemotokari vakatarisana ne:
- mafuta anofambira mberi;
- kubuda kwepombi;
- kudikitira kwezvisimbiso zvemafuta uye gaskets;
- isina kugadzikana crankshaft kumhanya;
- injini kupisa.
Zvakadaro, dambudziko guru reinjini ndiko kuparadzwa kwega kwetambo muhumburumbira. Nekuda kweizvi, mabhaudhi emusoro wecylinder anodonha, kusimba kwakatyoka uye kudonha kunotonhorera kunooneka. Mune ramangwana, izvi zvinogona kutungamirira mukuputsika kwejometri yebhokisi pachayo uye musoro we cylinder. Toyota yakabvuma kukanganisa kwedhizaini uye yakavandudza maburi ane shinda. Muna 2011, kit yekugadzirisa yemakwenzi ane thread yakaburitswa kuti igadziriswe.
Motor kuchengetedza
Sezviri pamutemo, mugadziri haapi kugadziridzwa kukuru kweiyo 2AZ-FXE simba unit. Kudzikira kuchengetedza kweinjini kwakajairwa kune mazhinji Lexus mota. 2AZ-FXE yakanga isiri iyo, saka, kana kukanganisa kwakakosha, nzira yakanakisisa yekugadzirisa dambudziko ndeyekutenga chibvumirano chemotokari.

- chip tuning;
- kuvandudzwa kwemaitiro ane hukama;
- pamusoro pekugadzirisa injini;
- kuiswa kwe turbocharger;
- kupindira kwakadzama.
Chip tuning inogona kungowedzera zvishoma simba. Inobvisa "kuomesa" kweinjini nemaitiro ezvakatipoteredza kubva kufekitari. Kuti uwane mhedzisiro yakakura, turbo kit yakakodzera. Nekudaro, kuwedzera kunoonekwa kwesimba kunodzivirirwa nekusakwana muganho wekuchengetedza kwecylinder block.
