ndi chiyani? Chipangizo ndi makhalidwe. Kanema.

Ngati tiyang'ana pa makhalidwe luso la Volkswagen, Audi, Skoda magalimoto, tidzaona injini mu mzere wa mayunitsi mphamvu, amene amafupikitsidwa monga FSI, TSI, TFSI. Talankhula kale za FSI pa Vodi.su autoportal yathu, m'nkhaniyi ndikufuna kukhala pamagulu amagetsi a TFSI mwatsatanetsatane.

TFSI imayimira chidule

Monga momwe mungaganizire, chilembo T chikutanthauza kukhalapo kwa turbine. Choncho, kusiyana kwakukulu kuchokera ku FSI ndi turbocharger, chifukwa chomwe mpweya wotulutsa mpweya umatenthedwanso, motero TFSI imasiyanitsidwa ndi mphamvu zawo komanso zachilengedwe - osachepera CO2 imalowa mumlengalenga.

Chidule cha TFSI chikuyimira Turbo mafuta stratified jakisoni, yomwe ingatanthauzidwe: injini ya turbocharged yokhala ndi jakisoni wamafuta opangidwa ndi stratified. Ndiko kuti, ndi kusintha, kwa nthawi yake, dongosolo la jekeseni mwachindunji mu chipinda choyaka moto cha pistoni ya munthu aliyense, yokhala ndi turbine.

Chifukwa cha njirayi, zotsatira zabwino zimatheka:

• mkulu injini mphamvu;
• torque wamkulu;
• kutsika kwamafuta amafuta, ngakhale injini zama turbocharged nthawi zambiri sizikhala zandalama.

Nthawi zambiri mtundu uwu wa mota umayikidwa pagalimoto ya Audi. Koma Volkswagen, Komano, amakonda kugwiritsa ntchito dongosolo ambiri ofanana pa magalimoto ake - TSI (turbo injini ndi jekeseni mwachindunji). FSI, nayonso, ilibe makina opangira magetsi.

Kwa nthawi yoyamba TFSI inayikidwa pa chitsanzo cha Audi A4. Mphamvu wagawo anali voliyumu 2 malita, pamene anapereka 200 ndiyamphamvu, ndi khama tractive anali 280 Nm. Kuti tikwaniritse zotsatira zomwezo pa injini ya mapangidwe oyambirira, iyenera kukhala ndi mlingo wa malita 3-3,5 ndikukhala ndi pistoni 6.

Mu 2011, akatswiri a Audi adakweza kwambiri TFSI. Masiku ano, gawo lachiwiri lamphamvu la malita awiri ili likuwonetsa izi:

• 211 HP pa 4300-6000 rpm;
• torque 350 Nm pa 1500-3200 rpm.

Ndiko kuti, ngakhale osakhala akatswiri amatha kuzindikira kuti injini zamtunduwu zimasiyanitsidwa ndi mphamvu zabwino pa liwiro lotsika komanso lalitali. Zokwanira kuyerekeza: mu 2011, Audi anasiya 3.2-lita FSI ndi 6 pistoni, amene anatulutsa 255 HP. pa 6500 rpm, ndi makokedwe a 330 Newton mamita linatheka pa 3-5 zikwi rpm.

Pano, mwachitsanzo, ndi makhalidwe a Audi A4 TFSI 1.8 lita, opangidwa mu 2007:

• mphamvu 160 hp pa 4500 rpm;
• makokedwe pazipita 250 Nm ndi kufika pa 1500 rpm;
• mathamangitsidwe mazana kumatenga 8,4 masekondi;
• kumwa m'matawuni (kutumiza kwapamanja) - 9.9 malita a A-95;
• kumwa pamsewu waukulu - 5.5 malita.

Ngati titenga mtundu wamtundu wa Audi A4 Allroad 2.0 TFSI Quattro, ndiye kuti TFSI yokhala ndi turbocharged ya TFSI imatha kupanga 252 HP. Mathamangitsidwe mazana amamutengera masekondi 6.1, ndi kumwa ndi malita 8,6 mu mzinda ndi kufala basi ndi malita 6,1 kunja kwa mzinda. Galimotoyo ili ndi mafuta a A-95.

Tsopano mverani kusiyana kwake. Volkswagen Passat 2.0 FSI:

• mphamvu 150 hp pa 6000 rpm;
• makokedwe - 200 Nm pa 3000 rpm;
• mathamangitsidwe mazana - 9,4 masekondi;
• m'tawuni, galimoto yokhala ndi makaniko imadya malita 11,4 a A-95;
• owonjezera m'tawuni mkombero - 6,4 malita.

Ndiko kuti, poyerekeza ndi FSI, TFSI injini wakhala sitepe patsogolo chifukwa unsembe wa turbocharger. Komabe, zosinthazo zidakhudzanso gawo lomanga.

Mapangidwe a injini za TFSI

Turbocharger imayikidwa muzitsulo zotulutsa mpweya, zomwe zimapanga gawo lofanana, ndipo mpweya woyaka pambuyo pake umaperekedwanso kuzinthu zambiri. Dongosolo loperekera mafuta lasinthidwa chifukwa chogwiritsa ntchito pampu yolimbikitsira m'chigawo chachiwiri, chomwe chimatha kupopera mphamvu zambiri.

Pampu yopangira mafuta imayang'aniridwa ndi gawo lamagetsi, kotero kuchuluka kwa mafuta osakanikirana ndi mpweya omwe amalowetsedwa mu pistoni kumadalira katundu wapano pa injini. Ngati ndi kotheka, kupanikizika kumawonjezeka, mwachitsanzo, ngati galimoto ikuyenda muzitsulo zotsika kutsika. Choncho, zinali zotheka kupeza ndalama zambiri pakugwiritsa ntchito mafuta.

Kusiyana kwina kwakukulu kuchokera ku FSI kuli pansi pa pistoni. Zipinda zoyaka moto mkati mwake ndi zazing'ono, koma nthawi yomweyo zimakhala ndi malo akuluakulu. Fomu iyi imakulolani kuti mugwire ntchito moyenera ndi kuchepetsedwa kwa digiri ya kuponderezana.

Ambiri, mayunitsi mphamvu TFSI ntchito mofanana ndi injini zina zonse nkhawa Volkswagen:

• madera awiri a dongosolo mafuta - otsika ndi mkulu kuthamanga;
• Kuthamanga kwapakati kumaphatikizapo: thanki, pampu yamafuta, zosefera zolimba komanso zabwino, sensor yamafuta;
• jekeseni mwachindunji, i.e. jekeseni, ndi gawo lofunikira la dera lothamanga kwambiri.

Njira zogwirira ntchito za zigawo zonse zimayendetsedwa ndi unit control unit. Zimagwira ntchito molingana ndi ma aligorivimu ovuta omwe amasanthula magawo osiyanasiyana a machitidwe agalimoto, pamaziko omwe malamulo amatumizidwa kwa ma actuators ndipo kuchuluka kwamafuta kumalowa m'dongosolo.

Komabe, ma injini a turbine amafunikira njira yapadera, ali ndi zovuta zingapo poyerekeza ndi mlengalenga wamba:

• mafuta apamwamba amafunikira;
• kukonza makina opangira magetsi ndikosangalatsa kokwera mtengo;
• kuchuluka zofunika mafuta injini.

Koma ubwino uli pa nkhope ndipo iwo kuposa kuphimba zonsezi zazing'ono kuipa.
