chii? Chishandiso uye maitiro. Vhidhiyo.

Kana tikatarisa hunyanzvi hunhu hweVolkswagen, Audi, Skoda mota, tichaona injini mumutsara wemayuniti emagetsi, ayo akapfupikiswa seFSI, TSI, TFSI. Takatotaura nezveFSI pane yedu Vodi.su autoportal, mune ino chinyorwa ndinoda kugara paTFSI magetsi mayuniti mune zvakadzama.

TFSI inomirira chidimbu

Sezvaungafungidzira, vara T rinoratidza kuvapo kweturbine. Nokudaro, musiyano mukuru kubva kuFSI ndiyo turbocharger, nekuda kwekuti magasi emhepo anopiswa zvakare, saka TFSI inosiyaniswa nekushanda kwavo uye kushamwaridzana kwezvakatipoteredza - shoma shoma ye CO2 inopinda mumhepo.

Muchidimbu TFSI inomirira Turbo mafuta stratified jekiseni, iyo inogona kushandurwa: turbocharged injini ine stratified mafuta jekiseni. Ndiko kuti, ishanduko, yenguva yayo, sisitimu yejekiseni yakananga mukamuri yekupisa yepiston yega yega, ine turbine.

Nekuda kweiyi nzira, mhedzisiro yakanaka inowanikwa:

• high injini simba;
• big torque;
• kushandiswa kwemafuta kwakaderera, kunyange zvazvo injini dze turbocharged dzichigara dzisina mari.

Kunyanya iyi mhando yemota inoiswa paAudi mota. Volkswagen, kune rumwe rutivi, inofarira kushandisa kazhinji yakafanana system mumotokari dzayo - TSI (turbo injini ine zvakananga jekiseni). FSI, zvakare, haina kugadzirwa neturbine.

Kekutanga TFSI yakaiswa paAudi A4 modhi. Chikwata chemagetsi chaive nevhoriyamu ye2 litita, apo ichipa mazana maviri emabhiza, uye iyo inoyevedza nhamburiko yaive 200 Nm. Kuti uwane mibairo yakafanana painjini yemagadzirirwo ekutanga, yaizofanira kunge iine vhoriyamu yeodha ye 280-3 malita uye ine 3,5 pistons.

Muna 2011, mainjiniya eAudi akasimudzira zvakanyanya TFSI. Nhasi, ichi chizvarwa chechipiri-mbiri-lita yemagetsi unit inoratidza zvinotevera maitiro:

• 211 HP pa 4300-6000 rpm;
• torque 350 Nm pa1500-3200 rpm.

Izvi zvinoreva, kunyange munhu asiri nyanzvi anogona kuona kuti injini dzemhando iyi dzinosiyaniswa nesimba rakanaka pane zvose zvakaderera uye zvepamusoro. Zvakwana kuenzanisa: muna 2011, Audi yakamisa 3.2-litre FSI ine 6 pistons, iyo yakagadzira 255 hp. pa 6500 rpm, uye torque ye 330 Newton mamita yakawanikwa pa 3-5 zviuru rpm.

Pano, semuenzaniso, ndiwo maitiro eAudi A4 TFSI 1.8 litre, yakabudiswa muna 2007:

• simba 160 hp pa4500 rpm;
• yakakura torque ye250 Nm inosvika pa1500 rpm;
• kukurumidza kusvika kumazana kunotora 8,4 masekondi;
• kushandiswa mumaguta ekutenderera (manual transmission) - 9.9 malita eA-95;
• kushandiswa mumugwagwa mukuru - 5.5 litita.

Kana tikatora ose-vhiri dhiraivha shanduro Audi A4 Allroad 2.0 TFSI Quattro, ipapo maviri-litre turbocharged TFSI inokwanisa kugadzira 252 hp. Kukwidza kumazana kunomutora 6.1 masekondi, uye kushandiswa kuri 8,6 litita muguta rine otomatiki hutachiwana uye 6,1 malita kunze kweguta. Motokari yakazadzwa neA-95 peturu.

Zvino inzwa musiyano. Volkswagen Passat 2.0 FSI:

• simba 150 hp pa6000 rpm;
• torque - 200 Nm pa 3000 rpm;
• kukurumidza kusvika kumazana - 9,4 masekondi;
• mumadhorobha, mota ine makanika inodya marita 11,4 eA-95;
• kuwedzera-muguta kutenderera - 6,4 malita.

Ndiko kuti, kana ichienzaniswa neFSI, injini yeTFSI yave nhanho yekumberi nekuda kwekuiswa kweturbocharger. Zvisinei, kuchinja kwakakanganisawo chikamu chinovaka.

Dhizaini maficha eTFSI injini

Iyo turbocharger inoiswa mune exhaust manifold, iyo inoumba yakajairwa module, uye iyo mushure mekupiswa gasi inopihwa zvakare kune yakawanda yekutora. Iko kushandiswa kwemafuta kwemafuta kwakashandurwa nekuda kwekushandiswa kwepombi yebooster muchikamu chechipiri, iyo inokwanisa kupomba zvakanyanya kudzvinyirira.

Iyo pombi yemafuta inodzorwa neiyo yemagetsi control unit, saka huwandu hwemafuta-mweya musanganiswa unopinzwa mupiston unoenderana nemutoro wazvino pane injini. Kana zvichidikanwa, kudzvinyirirwa kunowedzera, somuenzaniso, kana motokari ichifamba mumagetsi akadzika pasi. Saka, zvaive zvichikwanisika kuwana mari yakakosha mukushandiswa kwemafuta.

Mumwe mutsauko wakakosha kubva kuFSI uri pasi pepistons. Makamuri ekupisa mukati mawo maduku, asi panguva imwechete anotora nzvimbo huru. Iyi fomu inokubvumira kuti ushande zvinobudirira nedhigirii rakaderedzwa rekumanikidza.

Kazhinji, TFSI masimba emagetsi anoshanda nenzira imwechete semamwe ese einjini eVolkswagen kunetseka:

• matunhu maviri emafuta system - yakaderera uye yakanyanya kudzvanywa;
• iyo yakaderera dhizaini yedunhu inosanganisira: tangi, pombi yemafuta, coarse uye yakanaka mafirita emafuta, sensor yemafuta;
• iyo yakananga jekiseni system, i.e. injector, chikamu chakakosha cheyakanyanya kudzvinyirira wedunhu.

Nzira dzekushanda dzezvikamu zvose zvinotungamirirwa nechikwata chekutonga. Inoshanda zvinoenderana neyakaomesesa algorithms inoongorora akasiyana ma parameter emotokari masisitimu, pahwaro hweiyo mirairo inotumirwa kune actuators uye yakanyatso kuyerwa huwandu hwemafuta inopinda muhurongwa.

Nekudaro, injini dzeturbine dzinoda nzira yakakosha, dzine huwandu hwekuipa kana uchienzaniswa neyakajairwa mumhepo:

• mafuta emhando yepamusoro anodiwa;
• kugadzirisa turbine mafaro anodhura;
• kuwedzera zvinodiwa zvemafuta einjini.

Asi zvakanakira zviri pachiso uye ivo vanopfuura kufukidza zvese izvi zvidiki zvakashata.
