menene? Na'ura da halaye. Bidiyo.

Idan muka dubi halayen fasaha na motoci na Volkswagen, Audi, Skoda, za mu ga injuna a cikin layin wutar lantarki, wanda aka rage a matsayin FSI, TSI, TFSI. Mun riga mun yi magana game da FSI akan tashar mu ta Vodi.su, a cikin wannan labarin Ina so in yi magana game da raka'a wutar lantarki ta TFSI daki-daki.

TFSI tana nufin gajarta

Kamar yadda zaku iya tsammani, harafin T yana nuna kasancewar injin turbin. Saboda haka, babban bambanci daga FSI shine turbocharger, godiya ga abin da iskar gas ya sake ƙonewa, don haka TFSI ya bambanta ta hanyar dacewa da kuma abokantakar muhalli - ƙananan adadin CO2 ya shiga cikin iska.

Gajartawar TFSI tana nufin Turbo oil stratified injection, wanda za'a iya fassarawa: injin turbocharged tare da allurar mai mai madaidaici. Wato juyin juya hali ne, a lokacinsa, tsarin allurar mai kai tsaye a cikin ɗakin konewar kowane piston, sanye take da injin turbine.

Godiya ga wannan hanyar, ana samun kyakkyawan sakamako:

• babban ƙarfin injin;
• babban karfin juyi;
• karancin man fetur da ake amfani da shi, kodayake injunan turbocharged a al'adance ba tattalin arziki bane.

Yawancin irin wannan motar ana sanyawa akan motocin Audi. Volkswagen, a daya bangaren, ya fi son yin amfani da tsarin gaba daya a cikin motocinsa - TSI (injin turbo tare da allura kai tsaye). FSI, bi da bi, ba a sanye take da injin turbin ba.

A karo na farko TFSI aka shigar a kan Audi A4 model. Naúrar wutar lantarki tana da ƙarar lita 2, yayin da take ba da ƙarfin dawakai 200, kuma ƙoƙarin da aka yi ya kasance Nm 280. Don cimma sakamako iri ɗaya akan injin ƙirar ƙirar farko, dole ne a sami ƙarar tsari na 3-3,5 lita kuma a sanye shi da pistons 6.

A cikin 2011, injiniyoyin Audi sun inganta TFSI sosai. A yau, wannan rukunin wutar lantarki mai lita biyu na ƙarni na biyu yana nuna halaye masu zuwa:

• 211 HP da 4300-6000 rpm;
• karfin juyi 350 nm a 1500-3200 rpm.

Wato, ko da wanda ba ƙwararru ba zai iya lura cewa injunan irin wannan nau'in ana bambanta su da iko mai kyau a duka ƙananan gudu da sauri. Ya isa a kwatanta: a cikin 2011, Audi ya dakatar da FSI 3.2-lita tare da pistons 6, wanda ya samar da 255 hp. a 6500 rpm, kuma an sami karfin juyi na 330 Newton mita a 3-5 dubu rpm.

A nan, misali, su ne halaye na Audi A4 TFSI 1.8 lita, samar a 2007:

• ikon 160 hp da 4500 rpm;
• matsakaicin karfin juyi na 250 Nm ya kai 1500 rpm;
• hanzari zuwa ɗaruruwan yana ɗaukar 8,4 seconds;
• amfani a cikin sake zagayowar birane (watsawa ta hannu) - 9.9 lita na A-95;
• amfani a kan babbar hanya - 5.5 lita.

Idan muka dauki nau'in motar motar Audi A4 Allroad 2.0 TFSI Quattro, to, TFSI-lita turbocharged yana iya haɓaka 252 hp. Acceleration zuwa ɗaruruwan yana ɗaukar shi 6.1 seconds, kuma amfani shine lita 8,6 a cikin birni tare da watsa atomatik da lita 6,1 a wajen birni. Motar na cike da man fetur A-95.

Yanzu ji bambanci. Volkswagen Passat 2.0 FSI:

• ikon 150 hp da 6000 rpm;
• karfin juyi - 200 Nm a 3000 rpm;
• hanzari zuwa daruruwan - 9,4 seconds;
• a cikin sake zagayowar birane, motar da ke da injina tana cinye lita 11,4 na A-95;
• karin-birane sake zagayowar - 6,4 lita.

Wato, idan aka kwatanta da FSI, injin TFSI ya zama mataki na gaba godiya ga shigar da turbocharger. Koyaya, sauye-sauyen kuma sun shafi sashin ma'ana.

Abubuwan ƙira na injunan TFSI

An shigar da turbocharger a cikin nau'in shaye-shaye, wanda ke samar da tsarin gama gari, kuma ana sake ba da iskar gas ɗin da aka kone a cikin nau'in ci. An canza tsarin samar da man fetur saboda amfani da famfo mai ƙarfafawa a cikin da'irar na biyu, wanda zai iya yin ƙarin matsa lamba.

Na'urar sarrafa wutar lantarki ce ke sarrafa fam ɗin mai, don haka adadin cakuda mai da iska da aka yi a cikin pistons ya dogara da nauyin da ke kan injin yanzu. Idan ya cancanta, ana ƙara matsa lamba, alal misali, idan motar tana motsawa a cikin ƙananan gears ƙasa. Don haka, ya yiwu a sami babban tanadi a cikin amfani da man fetur.

Wani muhimmin bambanci daga FSI yana cikin kasan pistons. Ƙungiyoyin konewa a cikinsu sun fi ƙanƙanta, amma a lokaci guda sun mamaye babban yanki. Wannan nau'i yana ba ku damar yin aiki yadda ya kamata tare da raguwar digiri na matsawa.

Gabaɗaya, raka'o'in wutar lantarki na TFSI suna aiki daidai da sauran injuna na damuwa na Volkswagen:

• nau'i biyu na tsarin man fetur - ƙananan da matsa lamba;
• da'irar ƙananan matsa lamba ya haɗa da: tanki, famfo mai mai, maɗaukaki da masu tace mai mai kyau, firikwensin mai;
• tsarin alluran kai tsaye, watau allurar, wani bangare ne na da'ira mai karfin gaske.

Hanyoyin aiki na duk abubuwan da aka gyara ana sarrafa su ta hanyar sarrafawa. Yana aiki bisa ga hadaddun algorithms wanda ke nazarin sigogi daban-daban na tsarin motar, bisa ga abin da aka aika umarni ga masu kunnawa kuma adadin mai ya shiga cikin tsarin.

Koyaya, injunan turbine suna buƙatar hanya ta musamman, suna da ƙarancin rashin amfani idan aka kwatanta da yanayin yanayi na al'ada:

• Ana buƙatar man fetur mai inganci;
• Gyaran injin turbin abu ne mai tsada mai tsada;
• ƙarin buƙatun don man inji.

Amma fa'idodin suna kan fuska kuma sun fi rufe duk waɗannan ƙananan lahani.
