FSI injini - ndichiyani? Mfundo ya ntchito, kusintha ndi kusiyana kwa injini zina zoyaka mkati

Kusiyana kwakukulu pamapangidwe amagetsi a FSI kuchokera ku zida zina zoyatsira zamakina kumakhala pakuperekedwa kwa petulo yothamanga kwambiri kudzera mumphuno molunjika kuchipinda choyaka.

Injini yamagalimoto pogwiritsa ntchito luso la FSI idapangidwa mu labotale ya nkhawa ya Mitsubishi, ndipo lero ma motors ngati awa adayikidwa kale pamitundu yambiri yamagalimoto ochokera kwa opanga osiyanasiyana aku Europe, America ndi Japan. Volkswagen ndi Audi moyenerera amaonedwa kuti ndi atsogoleri kupanga mayunitsi FSI mphamvu, pafupifupi onse amene magalimoto ndi okonzeka ndi injini izi. Kuwonjezera pa iwo, injini zimenezi, koma mabuku ang'onoang'ono, anaika pa magalimoto awo: BMW, Ford, Mazda, Infiniti, Hyundai, Mercedes-Benz ndi General Motors.

Kugwiritsa ntchito injini za FSI kumachepetsa kwambiri mpweya woipa wa magalimoto ndipo kumachepetsa kugwiritsa ntchito mafuta ndi 10-15%.

Kusiyana kwakukulu kuchokera ku mapangidwe akale

Chofunikira chosiyanitsa cha FSI ndi kukhalapo kwa machitidwe awiri otsatizana amafuta omwe amapereka mafuta. Yoyamba ndi njira yochepetsera yomwe imayenda mozungulira mafuta yolumikizira tanki ya gasi, pampu yozungulira, strainer, sensor yowongolera, ndi payipi yoperekera mafuta ku dongosolo lachiwiri.

Dera lachiwiri limapereka mafuta kwa jekeseni wopopera mankhwala ndi kupereka kwa masilindala kuti awotche ndipo, chifukwa chake, amagwira ntchito zamakina.

Mfundo ya ntchito ya contours

Ntchito ya dera loyamba lozungulira ndikupereka mafuta kwa wachiwiri. Amapereka kuyendayenda kwamafuta kosalekeza pakati pa thanki yamafuta ndi chipangizo chojambulira mafuta, chomwe chimayikidwa ngati chopopera.

Kusunga mawonekedwe ozungulira nthawi zonse kumaperekedwa ndi pampu yomwe ili mu tanki ya gasi. Sensa yomwe idayikidwapo nthawi zonse imayang'anira kuchuluka kwamphamvu m'derali ndikutumiza chidziwitsochi kugawo lamagetsi, lomwe, ngati kuli kofunikira, lingasinthe magwiridwe antchito a pampu kuti pakhale mpweya wokhazikika wamafuta kudera lachiwiri.

Ntchito ya dera lachiwiri ndikuwonetsetsa kuti mafuta ofunikira amaperekedwa m'zipinda zoyaka moto za injini.

Kuchita izi, kumaphatikizapo:

• mpope wodyetsa wamtundu wa plunger kuti apange mphamvu yofunikira yamafuta akaperekedwa kumphuno;
• chowongolera chomwe chimayikidwa mu mpope kuti chiwonetsetse kuti mafuta ali ndi mita;
• kuthamanga kusintha kulamulira sensa;
• nozzle kupopera mafuta pa jekeseni;
• njira yogawa;
• valavu chitetezo, kuteteza zinthu za dongosolo.

Kugwirizana kwa ntchito ya zinthu zonse kumaperekedwa ndi chipangizo chapadera chowongolera zamagetsi kudzera mwa actuators. Kuti mupeze chisakanizo chapamwamba choyaka moto, mita yoyendera mpweya, chowongolera mpweya ndi ma drive owongolera mpweya amayikidwa. Zida zamagetsi zamagetsi zimapereka chiŵerengero cha kuchuluka kwa mafuta a atomized ndi mpweya wofunikira kuti uyake, wotchulidwa ndi pulogalamuyo.

Mwa njira, pa tsamba lathu la vodi.su, pali nkhani yomwe mudzaphunzire momwe mungagwiritsire ntchito injini yofulumira.

Kusintha kwa mfundo

Mu ntchito ya injini FSI, pali mitundu itatu ya mapangidwe osakaniza kuyaka, kutengera katundu pa injini:

• homogeneous stoichiometric, yopangidwa kuti igwire ntchito yamagetsi pa liwiro lalikulu komanso katundu wolemetsa;
• homogeneous homogeneous, kwa ntchito yamagalimoto mumayendedwe apakatikati;
• zosanjikiza, zopangira injini pa liwiro lapakati komanso lotsika.

Pachiyambi choyamba, malo a throttle air damper amatsimikiziridwa malinga ndi malo a accelerator, ma dampers olowa amatseguka, ndipo jekeseni wamafuta amapezeka pamtundu uliwonse wa injini. The coefficient of owonjezera mpweya kwa kuyaka mafuta ndi wofanana ndi mmodzi ndi bwino kuyaka zimatheka mu njira imeneyi ntchito.

Pa injini yapakatikati, valavu yotulutsa mpweya imatsegulidwa mokwanira ndipo ma valve olowetsa amatsekedwa, chifukwa chake, mpweya wochuluka umasungidwa pa 1,5 ndipo mpaka 25% ya mpweya wotulutsa mpweya ukhoza kusakanikirana ndi mafuta osakaniza kuti agwire bwino ntchito.

Mu stratified carburetion, zoyatsira zotsekemera zimatsekedwa, ndipo valavu yotsekemera imatsekedwa ndikutsegulidwa malinga ndi katundu wa injini. Mpweya wochuluka wa mpweya uli pakati pa 1,5 mpaka 3,0. The otsala owonjezera mpweya mu nkhani iyi amasewera ntchito yothandiza kutentha insulator.

Monga mukuonera, mfundo yoyendetsera injini ya FSI imachokera pakusintha kuchuluka kwa mpweya woperekedwa pokonzekera kusakaniza koyaka, pokhapokha ngati mafuta aperekedwa mwachindunji ku chipinda choyaka moto kudzera mumphuno yopopera. Mafuta ndi mpweya zimayendetsedwa ndi masensa, actuators ndi magetsi injini control unit.
