FSI engines: zvayakanakira nezvayakaipira zveFSI injini

Mumota dzemazuva ano dzemavhiri mana, iwo mamodheru ayo akashongedzerwa neakananga jekiseni mafuta system ari kuwana mukurumbira mukuru. Nhasi, pane zvakawanda zvakasiyana nadzurudzo.

Iyo fsi tekinoroji inoonekwa seimwe yepamusoro. Ngatizvizivei zvirinani: ndeipi peculiarity uye kuti yakasiyana sei neanalog yayo Gdi?

Chii chinonzi FSI jekiseni system?

Uku kukura kwakaunzwa nevatyairi Volkswagen. Muchokwadi, iyi peturu yekupa system iyo inoshanda musimboti wakafanana kune yakafanana chiJapan mushanduro (inonzi gdi) yakavapo kwenguva yakareba. Asi, sevamiriri vekunetseka vanovimbisa, iyo TS inoshanda pane rakasiyana musimboti.

Injini, iyo ine FSI bheji pachivharo, inoshongedzerwa nemafuta ejekiseni akaisirwa padhuze nepaki dzekutsvaira - mumusoro wega wega wega. Peturu inodyiswa yakananga mukamuri reshinda rinoshanda, ndosaka ichinzi "yakananga".

The musiyano mukuru pakati akazviratidza analoginen - mumwe mainjiniya wekambani akashanda kubvisa kutadza kweJapan system. Nekuda kweizvi, mota yakangofanana, asi yakagadziridzwa zvishoma yakaonekwa mune auto world, umo mafuta anosanganiswa nemhepo zvakananga mukamuri re humburumbira.

Mashandiro anoita FSI injini

Mugadziri akapatsanura system yese kuita maviri macircuit. Kazhinji peturu inoendeswa pasi pekumanikidza kwakaderera. Inosvika pakakwirira pombi yemafuta uye inoungana munjanji. Pombi yekumanikidza yakakwira inoteverwa neseketi inoitwa kumanikidza kwakanyanya

Mudunhu rekutanga, pombi yakadzika yekumanikidza inoiswa (kazhinji mutangi yegasi), sensor inogadzirisa kumanikidza mudunhu, uye firita yemafuta.

Zvese zvinhu zvakakosha zvinowanikwa mushure mejekiseni pombi. Iyi nzira inochengetedza musoro wenguva dzose, uyo unoona jekiseni remafuta rakagadzikana. Iyo yemagetsi control unit inogamuchira dhata kubva kune yakaderera kumanikidza sensor uye inogonesa iyo huru peturu pombi zvinoenderana nekushandisa kwemafuta kweye peturu njanji.

Iyo yakanyanya kumanikidza peturu iri muchitima, uko kwakabatana kwakabatana jekiseni kune imwe humburumbira. Imwe sensor yakaiswa mudunhu, iyo inoendesa masaini kuECU. Iyo yemagetsi inogonesa iyo dhiraivha yepombi peturu pombi, iyo inoshanda sebhatiri.

Saka kuti zvikamu zvirege kuputika kubva pakamanikidzwa, pane vharafu yakakosha munjanji (kana peturu isina kugadzirirwa nekuyerera kwekudzoka, saka iri mutangi pachayo), iyo inoderedza zvakanyanya kumanikidza. Zvemagetsi zvinoparadzira mashandiro ejekiseni zvinoenderana nesitiroko inoitwa mumasirinda.

Piston yemayuniti akadaro ichave neyakagadzirirwa dhizaini, iyo inovimbisa kugadzirwa kwema vortices mudumbu. Mhedzisiro iyi inobvumidza mweya kusanganisa zvirinani nepeturu ine atomized.

Iyo peculiarity yeshanduko iyi ndeyekuti inobvumira:

• Wedzera simba reinjini yemukati yemoto;
• Deredza peturu yekushandisa nekuda kweakawanda mafuta anowedzera;
• Deredza kusvibiswa, sezvo BTC ichipisa zvakanyanya, ichiita kuti chinaku chinake pakuita basa rayo.

Yakakwira yekumanikidza peturu pombi

Imwe yemaitiro akakosha emhando iyi yemafuta pombi, iyo inogadzira kumanikidza kwakawanda mudunhu. Ipo injini ichimhanya, chinhu ichi chinopomba peturu mudunhu, nekuti ine hukama hwakaomarara kune camshaft. Mamwe mashoko nezve dhizaini yezvigadzirwa zvinotsanangurwa zvakasiyana.

Dzvinyiriro yakasimba mudunhu inofanirwa nechikonzero chekuti peturu haina kupihwa kune yakawanda yekudyira, senge mune mono jekiseni kana neyakagoverwa mafuta, asi kumasirinda pachawo. Iwo musimboti unenge wakafanana nemashandiro anoita injini yedhiziri.

Kuti chikamu chisangopinda mukamuri yemoto, asi kumwaya, kumanikidza kuri mudunhu kunofanirwa kuve kwakanyanya kupfuura index yekumanikidza. Nechikonzero ichi, vagadziri havagone kushandisa zvakajairika pombi dzemafuta, izvo zvinongomanikidza kusvika hafu yemhepo.

FSI jekiseni pombi basa kutenderera

Kuti mudziyo ushande nemazvo, ichipa kumanikidza kwakadzikama, mota inofanirwa kuve yakagadziriswa nepombi pombi. Chii chinonzi plunger uye mashandiro ayo mune imwe wongororo.

Ose mashandiro epombi anogona kukamurwa mune anotevera modes:

1. Kubvisa peturu. Iyo plunger inotakurirwa muchirimo inoderedzwa kuti ivhure vharuvhu yekukweva. Peturu inouya kubva kune yakaderera kumanikidza wedunhu;
2. Kumanikidza kuvaka-up. Chigunwe cheplunger chinokwira kumusoro. Iyo inlet vharuvhu inovhara, uye nekuda kwekumanikidza kwakaburitswa, vharuvhu yekubuditsa inovhura, kuburikidza iyo peturu inoyerera ichipinda mudunhu rezvitima;
3. Kudzvinyirira kudzora. Mune akajairwa maitiro, iyo vharuvhu inoramba isingashande. Kana mangoda emafuta achinge anyanya, iyo inodzora inopindirana nechiratidzo che sensor uye inogonesa vharuvhu yekurasa, inoiswa padhuze nepombi yemafuta ekumanikidza (kana sisitimu ine kuyerera kwekudzoka). Gasi rakawandisa rinodzorerwa mutangi repeturu.

Musiyano uripo pakati peinjini dzeFSI kubva kuTSI, GDI nevamwe

Nekudaro, iyo musimboti weiyo system iri pachena. Saka, zvasiyana sei kubva kune fanano yekuti yainzi fsi? Musiyano mukuru ndewokuti inoshandisa yakajairwa kamwene, iyo atomizer iyo isingagadzi vortex mukati mekamuri.

Zvakare, ino sisitimu inoshandisa yakapusa jekiseni pombi dhizaini pane gdi. Chimwe chiitiko chimiro chisina kujairika chepiston korona. Iyi nadzurudzo inopa yakakamurwa, "yakaturikidzana" mafuta ekugovera. Kutanga, chikamu chidiki che peturu chinojowa, uye pakupera kwekumanikidza sitiroko, iyo yasara yeiyo yakapihwa chikamu.

"Chironda" chikuru chemota dzakadai, senge echiJapan akafanana, chiGerman nevamwe, ndechekuti majekiseni avo anowanzo coke. Kazhinji, kushandiswa kwezvokuwedzera kunononoka kudiwa kwekuchenesa zvinodhura kana kutsiva zvikamu izvi zvishoma, asi nekuda kweichi chikonzero vamwe vanhu vanoramba kutenga mota dzakadai.

FSI mota zvigadzirwa

Sezvo mugadziri wega wega achipa zita rayo kusisitimu iyi, zvine hungwaru zvichiratidza kuti mainjiniya avo akwanisa kugadzira jekiseni "risina matambudziko", musimboti unoramba wakafanana kunze kwekusiyana kwediki dhizaini.

FSI motors ndiyo brainchild yeiyo VAG kunetsekana. Neichi chikonzero, iwo mamodheru anogadzirwa neichi chiratidzo anozove akashongedzerwa navo. Iwe unogona kuverenga nezve izvo makambani ari chikamu chekunetseka pano... Muchidimbu, pasi pehodhi yeVW, Skoda, Seat neAudi unogona kuwana zviuno zvine simba zvakadaro.

Heino pfupi vhidhiyo kuongororwa kweakajairika maronda eimwe yedambudziko mayuniti:

Injini yeFSI yakatanga zvese. Matambudziko nezvakaipa zveinjini ye1.6 FSI (BAG).

Mibvunzo nemhinduro:

Chii chinonzi FSI uye TSI? TSI iine mbiri-inochaja yemukati injini yekupisa ine stratified jekiseni mafuta system. FSI imota ine maviri anoteedzana mafuta masisitimu (yakaderera uye yakakwira pressure circuit) ine mafuta atomization mucylinder.

Ndeipi yakanakisa TSI kana FSI injini? Musiyano uripo pakati peinjini idzi uripo chete pamberi pe turbocharging. Injini yeturbine inopedza mafuta mashoma, asi iine simba rakawanda uye mutengo wepamusoro wekugadzirisa.
