Zvinyorwa 3ZR-FE

Iyo 3ZR-FE inline ina-cylinder yemukati inopisa peturu injini. Iyo gasi yekugovera michina ndeye 16-vharuvhu, yakagadzirwa zvinoenderana neiyo DOHC chirongwa, ine maviri camshafts. Iyo cylinder block ndeye-chimwe-chidimbu chakakandwa, iyo yakazara injini kutamiswa marita maviri. Nguva yekutyaira mhando - cheni.

Yakakosha yakasarudzika yeiyi nhevedzano yaive Dual VVT-I uye Valvematic, yakagadziridzwa semhinduro kuValvetronic system kubva kuBMW neVVEL kubva kuNissan.

Dual VVT-I ndeye advanced intelligent valve timing system inoshandura nguva dzekuvhura kwete yekudya chete asiwo mavharuvhu ekupedza. Asi, sezvakaratidzwa netsika, hapana chitsva chakatangwa. Kunyanya nzira yekushambadzira neToyota, yakaitwa mukupindura kuvandudzwa kwevanokwikwidza. Standard VVT-I clutches ikozvino yave pane ese ari maviri enguva camshafts, akabatana kwete chete nekutora, asiwo kune mavharuvhu ekupedza. Kushanda pasi pekutonga kwemagetsi komputa unit, iyo Dual VVT-I sisitimu inoita kuti hunhu hweinjini huwedzere kufanana maererano ne torque kupesana nekumhanya kwe crankshaft.

Imwe yakanyatsobudirira innovation yaive yeValvematic air-fuel ratio control system. Zvichienderana nejini yekushandisa mode, urefu hwekurohwa kwevhavha yekutora hunochinja, kusarudza kuumbwa kwakanyatsonaka kwemagungano emafuta. Iyo sisitimu inodzorwa neyemagetsi computing unit iyo inoramba ichiunganidza uye kugadzirisa data pane injini kushanda. Nekuda kweizvozvo, iyo Valvematic system yakasununguka kubva kune dips uye kunonoka kwakabatana nemakanika kutonga nzira. Nekuda kweizvozvo, injini yeToyota 3ZR-FE yakaratidza kuve yehupfumi uye "inoteerera" simba reyuniti, yepamusoro muhunhu hwayo kune yakafanana peturu mukati memoto injini.

Chokwadi chinofadza. Brazil, nyika inogadzira shuga hurusa pasi rose, inobudirira kuichinja kuva ethanol, iyo inoshandiswa sehuni dzeinjini dzinobatirira mukati mepeturu. Zvechokwadi, Toyota haana kuda kusiya misika yakadaro inoedza, uye muna 2010 yakagadzirisazve 3ZR-FE modhi kuti ishandise rudzi urwu rwemafuta. Iyo modhi nyowani yakagamuchira prefix FFV kune zita, zvinoreva "multi-fuel injini".

Kusimba uye kushaya simba kwe3ZR-FE

Kazhinji, injini yakabudirira. Iine simba uye ine hupfumi, inoratidza yakagadzikana torque maitiro pamusoro inenge yese crankshaft yekumhanyisa renji. Kushongedza iyo Valvematic sisitimu yakave nemhedzisiro yakanaka pa "kupindura" kwe3ZR-FE kudzvanya accelerator pedal uye nekuchinja kamwe kamwe mumitoro maitiro.

Kuipa kwacho kwakajairika. Kushaikwa kwekugadzirisa zviyero zve cylinder block. Iyo yekumhanyisa cheni drive, yakaitwa zvisina kubudirira, zvekuti yave nguva yekutaura nezve injini sosi ye200 km, kureva, kusvika ketani yakundikana.

Maererano neDual VVT-I system, mafuta e3ZR-FE anofanira kusarudzwa zvakanyatsonaka. Kunyanya kukora, zvinotungamira kuparara kwegasi rekugovera michina. Nyanzvi zhinji dzinokurudzira 0w40.
