FSI (Volkswagen) injini - rudzii injini, unhu
Injini yeFSI ndiyo yazvino uye ine hushamwari system, yatinoziva zviri nani sejekiseni rakananga. Iyi sisitimu yakagadzirwa mukutanga kwe2000s neVolkswagen uye yakashandiswa kumotokari dzeAudi. Vamwe vagadziri vemotokari vakaitawo budiriro yavo munzira iyi, uye mamwe mapfupi anoshandiswa kune einjini yavo:
- Reno - IDE;
- Alfa Romeo - JTS;
- Mercedes - CGI;
- Mitsubishi - GDI;
- Ford - EcoBoost uye zvichingodaro.
Asi injini dzese idzi dzakavakwa pamusimboti mumwe chete.
Zvimiro zverudzi urwu rweinjini ndezvizvi:
- kuvapo kwemafuta maviri ekuyerera maitiro - pasi uye high pressure circuits;
- pombi yemafuta yakaiswa yakananga mutangi pombi peturu muhurongwa pakumanikidzwa kweanenge 0,5 MPa, kushanda kwepombi kunodzorwa neiyo control unit;
- iyo pombi yepombi inoputira chete yakanyatso kuyerwa huwandu hwemafuta, iyi chiyero inotarwa neiyo control unit inoenderana nedata kubva kune dzakasiyana siyana sensors, pulses inopinda pombi inoita kuti ishande nesimba rakawanda kana shoma.
Iyo yakanyanya kudzvanywa yedunhu inokonzeresa kupa iyo cylinder block nemafuta. peturu inopombwa muchinjanji nepombi ine simba guru. Kumanikidzwa muhurongwa pano kunosvika chiratidzo che 10-11 MPa. Iyo rampu ichubhu inoitisa mafuta ine mhuno kumagumo, muromo wega wega uri pasi pekumanikidzwa kukuru unopinza huwandu hunodiwa hwepeturu mumakamuri ekupisa emapistoni. peturu yakasanganiswa nemhepo yatove mukamuri yekupisa, uye kwete mune yakawanda yekudyara, senge mune yekare-style carburetor uye jekiseni injini. Muchivharo chesilinda, musanganiswa wemhepo-mafuta anoputika pasi pechiito chepamusoro-soro uye spark, uye inogadzirisa mapistoni mukufamba.
Zvinhu zvakakosha zveiyo high pressure circuit ndezvekuti:
- mafuta ekumanikidza regulator - inopa chaiyo dosi ye peturu;
- chengetedzo uye bypass mavharuvhu - ivo vanokutendera kuti udzivise kuwedzera kwakanyanya kwekumanikidza muhurongwa, kubuda kunoitika nekuburitsa yakawandisa gasi kana mafuta kubva muhurongwa;
- pressure sensor - inoyera mwero wekumanikidza muhurongwa uye inodyisa ruzivo urwu kune control unit.
Sezvauri kuona, nekuda kweiyo sisitimu yechigadzirwa, zvakave zvichikwanisika kuchengetedza zvakanyanya huwandu hwepeturu inopedzwa. Zvisinei, kuitira basa rakanyatsorongeka, zvaive zvakakodzera kugadzira zvirongwa zvekugadzirisa zvakaoma uye kuisa motokari nemhando dzose dze sensor. Kukundikana mukushanda kweiyo control unit kana chero masensa anogona kutungamirira kumamiriro ezvinhu asingatarisirwi.
Zvakare, majekiseni akananga anotarisisa kunaka kwekuchenesa mafuta, saka zvinodikanwa zvakakwirira zvinoiswa pamafirita emafuta, ayo anofanirwa kuchinjwa zvichienderana nemirairo iri mubhuku remotokari.
Izvo zvakakoshawo kuti injini dzakadai dzinopa kupisa kunenge kwakazara kwemafuta, zvichiteerana, huwandu hushoma hwezvinhu zvinokuvadza hunoburitswa mumhepo pamwe nemagasi emhepo. Nekuda kwezvigadzirwa zvakadaro, zvakagoneka kuvandudza zvakanyanya mamiriro ezvakatipoteredza munyika dzeEurope, North America neSoutheast Asia.
Muvhidhiyo iyi uchaona uye kunzwa kuti 2-litre inodziya FSI injini inoshanda sei nekumhanya kwe100 zviuru zvemakiromita.
