Jet injini 1.4 t - chii chakakosha kuziva?

Pakugadzira chizvarwa ichi, Fiat akataura kuti 1.4 T Jet injini (semamwe mayuniti kubva kumhuri iyi) ichabatanidza tsika yepamusoro yebasa uye kutyaira kwehupfumi. Mhinduro yedambudziko iri yaive musanganiswa mutsva weturbocharger uye inodzorwa musanganiswa gadziriro. Kuunza ruzivo rwakakosha nezve 1.4T Jet kubva kuFiat!

Jet injini 1.4 t - ruzivo rwekutanga

Chikwata chinowanikwa mumhando mbiri - iyo isina simba ine simba re 120 hp, uye yakasimba ine 150 hp. Mienzaniso yakagadzirwa nevagadziri veFiat Powertrain Technologies vane dhizaini yakavakirwa pane imwe injini inozivikanwa - 1.4 16V Moto. Nekudaro, ivo vakagadziridzwa zvakare nekuda kwekudiwa kwekuisa turbo.

Iyo 1.4 T jet injini inosiyaniswa nekuti inopa simba rakakura rakaringana uye panguva imwechete yehupfumi hwekushandisa mafuta. Iyo zvakare ine yakafara rev rev uye yakanaka kwazvo giya yekuchinja mhinduro. 

Fiat unit technical data

Iyo 1.4 T Jet injini ndeye DOHC inline-mana injini ine 4 mavharuvhu pahumburumbira. Midziyo yeyuniti inosanganisira yemagetsi, yakawanda-point mafuta jekiseni, pamwe ne turbocharging. Injini yakaburitswa muna 2007 uye yakapihwa akawanda se9 sarudzo dzemagetsi: 105, 120, 135, 140 (Abarth 500C), 150, 155, 160, 180 uye 200 hp. (Abarth 500 Assetto Corse). 

Iyo 1.4 t jet injini ine bhandi dhiraivha uye isina kunanga mafuta jekiseni. Izvo zvinofanirwa kucherechedzwa kuti iyo unit haina akawanda akaoma maumbirwo zvinhu - kunze kweiyo turbocharger, iyo inoita kuti zvive nyore kuchengetedza. 

Hunhu hwekugadzirwa kwejini injini 1.4 matani.

Muchiitiko che 1.4 T Jet, cylinder block inogadzirwa nesimbi yakakandwa uye ine yakanyanya kusimba yemagetsi. Chikamu chezasi che crankcase chakagadzirwa ne die-cast aluminium alloy uye chikamu cheiyo inotakura-inotakura chimiro pamwe neiyo huru crankcase. 

Iyo inotora mitoro inogadzirwa ne crankshaft uye zvakare inoumba nhengo yakasimba negiya bhokisi kuburikidza neruvoko rwekuita. Inoitawo basa rekugadzirisa kutakura kweaxle shaft yakarurama. Iyo 1.4 T injini zvakare inoratidzira sere-chiyero chakagadzirwa simbi crankshaft, induction yakaomeswa crankshaft uye mashanu mabheji.

Kusanganiswa kwe turbocharger ine intercooler uye bypass valve - misiyano kubva kune aggregate vhezheni

Mubatanidzwa uyu wakagadzirwa zvakanyanya kune maviri akabuda einjini ye1.4 T-Jet. Zvisinei, pane misiyano pakati pemhando idzi. Ndezvei? 

1. Kune injini ine simba shoma, turbine vhiri geometry inovimbisa yakanyanya kudzvanywa pama torque epamusoro. Kuvonga kune izvi, kukwanisa kwakakwana kwechikwata kunogona kushandiswa. 
2. Zvakare, mushanduro ine simba kwazvo, kudzvanywa kunowedzera zvakanyanya kuvonga kune overboost, iyo inowedzera torque kusvika pakakwirira 230 Nm newastegate yakavharwa. Nokuda kwechikonzero ichi, kushanda kwezvikwata zvemitambo kunotonyanya kushamisa.

Kushanda Kwechikamu - Matambudziko Anowanikwa

Imwe yeakanyanya kukanganisa zvikamu zve 1.4 T Jet injini ndiyo turbocharger. Dambudziko rinowanzoitika ikesi yakatsemuka. Izvi zvinoratidzwa nemuridzo wehunhu, utsi kubva pakupera uye zvishoma nezvishoma kupera simba. Izvo zvakakosha kucherechedza kuti izvi zvinonyanya kushanda kune IHI turbine mauniti - akashongedzerwa neGarrett zvikamu, haana kunyanya kukanganisa.

Mamiriro ematambudziko anosanganisirawo kurasikirwa kwekutonhodza. Kusashanda zvakanaka kunogona kuongororwa kana mavara achionekwa pasi pemotokari. Kune zvakare kusashanda kwakabatana nekudonha kweinjini mafuta - chikonzero chinogona kunge chiri kusashanda kwebhobhi kana sensor. 

Nzira yekugadzirisa sei 1.4 T-Jet injini matambudziko?

Kutarisana nehupenyu hupfupi hwe turbocharger, mhinduro yakanaka ndeyekutsiva mabhoti emafuta emafuta ne turbine yemafuta. Izvi zvinokonzerwa nekuti mukati mechinhu ichi pane diki sefa inoderedza kudzora kwe rotor kana kurasikirwa kwekusimba. Nekudaro, kana paine matambudziko neheatsink, zvakanakisa kutsiva chikamu chose. 

Pasinei nekukanganisa, iyo 1.4 T jet injini inogona kuongororwa sechinhu chinoshanda zvakanaka. Iko hakuna kushayikwa kwezvikamu zvakasara, zvinogona kuenderana neLPG kuisirwa uye inopa kuita kwakanaka - semuenzaniso, mune iyo Fiat Bravo, iri kubva 7 kusvika 10 masekonzi kusvika 100 km / h.

Panguva imwecheteyo, ine mari yakawanda - inenge 7/9 malita pa 100 km. Sevhisi yenguva dzose, kunyangwe bhandi renguva yega yega 120 km. km, kana vhiri rinoyangarara ega ega 150-200 zviuru zvemakiromita, inofanirwa kukwana kutora mukana we1,4-t jet unit kwenguva yakareba uye kurekodha yakakwira mamaira.
