Lexus HS250h injini

Lexus HS250h ndi galimoto yapamwamba yopangidwa ku Japan yopangidwa ndi haibridi. Malinga ndi chidziwitso cha boma, chidule cha HS chikuyimira Harmonious Sedan, kutanthauza sedan yogwirizana. Galimotoyo inalengedwa ndi chisamaliro cha chilengedwe, koma nthawi yomweyo imatha kupereka mphamvu zovomerezeka zoyendetsera masewera. Kuti achite izi, Lexus HS250h imagwiritsa ntchito injini yoyatsira yamkati yamasilinda anayi molumikizana ndi injini yamagetsi.

Kufotokozera mwachidule za galimotoyo

Mtundu wosakanizidwa wa Lexus HS250h unayambitsidwa koyamba ku North America International Auto Show mu Januwale 2009. Galimotoyo idayamba kugulitsidwa mu Julayi 2009 ku Japan. Patatha mwezi umodzi, malonda anayamba ku United States. Galimotoyo inakhala imodzi mwazoyamba mu gawo la sedans yapamwamba yokhala ndi magetsi osakanizidwa.

Lexus HS250h imachokera ku Toyota Avensis. Galimotoyo ili ndi mawonekedwe owala komanso ma aerodynamics abwino. Galimotoyo imaphatikiza chitonthozo chabwino komanso chothandiza. Kuyendetsa molimba mtima komanso kusamalira bwino kumaperekedwa ndi kuyimitsidwa kosinthika kosinthika kodziyimira pawokha.

Mawonekedwe a Lexus HS250h

Mkati mwa Lexus HS250h amapangidwa pogwiritsa ntchito bioplastics zomera. Zimaphatikizapo mbewu za castor ndi kenaf fibers. Izi zinapangitsa kuti athe kusamalira chilengedwe ndikupanga galimoto "yobiriwira". Mkati ndi lalikulu ndithu, ndi dalaivala ndi okwera mipando ndi omasuka.

Galimotoyi ili ndi zida zamagetsi zogwira ntchito kwambiri. Chowongolera cha multimedia chokhala ndi touch control chidakhala chosavuta kugwiritsa ntchito. Central console ili ndi chophimba chotsitsimutsa. Mawonekedwe azithunzi amaganiziridwa bwino ndipo amapereka mwayi wopezeka pazinthu zambiri zothandiza. The touchpad ili ndi mayankho osavuta kuti azitha kugwiritsidwa ntchito bwino.

Chitonthozo si otsika pa chitetezo cha Lexus HS250h. Dongosolo lanzeru la IHB limazindikira kukhalapo kwa magalimoto ndikusintha mawonekedwe kuti apewe kuwala. Kuwongolera maulendo oyenda ndi LKA kumapangitsa galimotoyo kukhala mumsewu wake. Lexus imayang'anira kugona kwa madalaivala, imazindikira ngozi zakugunda ndikuchenjeza za zopinga zomwe zili panjira.

Injini pansi pa nyumba Lexus HS250h

Pansi pa nyumba ya Lexus HS250h ndi 2.4-lita 2AZ-FXE inline-four hybrid powertrain. Galimotoyo idasankhidwa potengera kuperekedwa kwa magwiridwe antchito okwanira popanda kuwonjezera mtengo wamafuta. The ICE ndi magetsi otengera torque yamagetsi kupita ku CVT kuti muzitha kuyendetsa bwino. Mphamvu yamagetsi imagwira ntchito mozungulira Atkinson ndipo imapereka kuthamangitsidwa kovomerezeka kwa sedan.

Chipinda cha injini Lexus HS250h chokhala ndi 2AZ-FXE

Injini ya 2AZ-FXE ndi yaphokoso kwambiri. Kuti muyendetse liwiro labwinobwino, muyenera kuthamanga kwambiri. Panthawi imodzimodziyo, phokoso lapadera limachokera ku injini, zomwe kudzipatula kwa phokoso sikungathe kupirira. Eni ake amagalimoto sakonda izi mochuluka, makamaka poganizira kuti mphamvu sizikugwirizana ndi kuchuluka kwa mphamvu yamagetsi. Chifukwa chake, Lexus HS250h yokhala ndi 2AZ-FXE ndiyabwino kwambiri pakuyendetsa mzinda, komwe imachita mwakachetechete komanso mofatsa.

Injini ya 2AZ-FXE ili ndi chipika cha aluminiyamu ya silinda. Manja achitsulo oponyedwa amaphatikizidwa muzinthu. Amakhala ndi malo akunja osagwirizana, omwe amatsimikizira kukhazikika kwawo mwamphamvu ndikuwongolera kutentha kwapang'onopang'ono. Pampu yamafuta a trochoid imayikidwa mu crankcase. Imayendetsedwa ndi unyolo wowonjezera, womwe umayambitsa kuchepa kwa kudalirika kwa gawo lamagetsi ndikuwonjezera kuchuluka kwa magawo osuntha.

Kapangidwe ka injini 2AZ-FXE

Mfundo ina yofooka pamapangidwe a mota ndi magiya a makina owongolera. Zapangidwa ndi zinthu za polima. Izi zinawonjezera chitonthozo ndi kuchepetsa phokoso la injini, koma zinayambitsa kusokonezeka pafupipafupi. Magiya a polima amatha msanga ndipo injini imataya mphamvu zake.

Mafotokozedwe a mphamvu yamagetsi

Injini ya 2AZ-FXE ili ndi ma pistoni opepuka a siketi a aloyi, mapini oyandama komanso zokutira zotsutsana ndi friction polima. Crankshaft yopangidwira imakhala ndi cholumikizira chogwirizana ndi mzere wa nkhwangwa za masilinda. Kuyendetsa nthawi kumayendetsedwa ndi unyolo wa mzere umodzi. Zina zonse zitha kupezeka mu tebulo ili m'munsimu.

Kudalirika ndi zofooka

Injini ya 2AZ-FXE sikungatchulidwe kuti yodalirika. Ili ndi zolakwika zingapo zamapangidwe zomwe zadzetsa mavuto amitundu yosiyanasiyana. Pafupifupi eni ake onse amagalimoto amakumana ndi izi:

• mafuta owonjezera owonjezera;
• kupopera kwa pampu;
• kutuluka thukuta kwa zisindikizo za mafuta ndi gaskets;
• liwiro losakhazikika la crankshaft;
• injini kutentha.

Komabe, vuto lalikulu la injini ndi kuwonongeka kwadzidzidzi kwa ulusi mu block ya silinda. Pachifukwa ichi, ma bolts amutu amagwa, zolimba zimasweka ndipo kutulutsa kozizirira kumawonekera. M'tsogolomu, izi zingayambitse kuphwanya geometry ya chipika palokha ndi mutu wa silinda. Toyota idavomereza cholakwika cha kapangidwe kake ndikuwongolera mabowo okhala ndi ulusi. Mu 2011, zida zokonzetsera za ulusi wa ulusi zidatulutsidwa kuti zikonzedwe.

Kuyika bushing yokhala ndi ulusi kuti muchepetse kulakwitsa kwa injini ya 2AZ-FXE

Kukhazikika kwagalimoto

Mwalamulo, wopanga samapereka kukonzanso kwakukulu kwa gawo lamagetsi la 2AZ-FXE. Kusakhazikika kwa injini kumakhala kofanana ndi magalimoto ambiri a Lexus. 2AZ-FXE analinso chimodzimodzi, choncho, ngati malfunction kwambiri, njira yabwino yothetsera vutoli ndi kugula galimoto mgwirizano. Pa nthawi yomweyo, otsika maintainability 2AZ-FXE amalipidwa ndi kudalirika mkulu wa magetsi.

Pali zovuta ndi kuthetsa mavuto ang'onoang'ono. Zida zosinthira zoyambirira nthawi zambiri sizigulitsidwa. Choncho, tikulimbikitsidwa kuchitira motere mosamala. Ndikofunika kukonza nthawi yake ndikudzaza mafuta apamwamba kwambiri.

Injini ikukonzekera Lexus HS250h

Injini ya 2AZ-FXE simakonda kusintha. eni galimoto ambiri amalangiza kuyamba Mokweza ndi m'malo ndi abwino kwambiri, mwachitsanzo, 2JZ-GTE. Posankha kuyimba 2AZ-FXE, pali mbali zingapo zazikulu:

• kukonza chip;
• kupititsa patsogolo machitidwe okhudzana;
• kukonza pamwamba pa injini;
• kukhazikitsa turbocharger;
• kulowererapo mozama.

Kusintha 2AZ-FXE

Kukonza chip kungangowonjezera mphamvu pang'ono. Imachotsa "kusokoneza" kwa injini ndi miyezo ya chilengedwe ku fakitale. Kuti mupeze zotsatira zochulukirapo, zida za turbo ndizoyenera. Komabe, kuwonjezeka kwakukulu kwa mphamvu kumalepheretsedwa ndi malire osakwanira a chitetezo cha cylinder block.
