FSI injini - chii ichocho? Nheyo yekushanda, kugadzirisa uye kusiyana kubva kune dzimwe injini dzinopisa mukati

Musiyano mukuru mukugadzirwa kweFSI magetsi mayuniti kubva kune mamwe ma mechanic combustion midziyo iri mukupihwa kwepamusoro-kudzvanywa peturu kuburikidza nemuromo wakananga mukamuri yekupisa.

Injini yemotokari inoshandisa tekinoroji yeFSI yakagadziridzwa murabhoritari yeMitsubishi kunetseka, uye nhasi mota dzakadaro dzakatoiswa pamhando dzakawanda dzemotokari kubva kune vakasiyana-siyana veEuropean, America neJapan vanogadzira. Volkswagen neAudi vanoonekwa sevatungamiri mukugadzirwa kweFSI magetsi emagetsi, anenge ese ane motokari dzave dzakagadzirirwa injini idzi. Mukuwedzera kwavari, injini dzakadaro, asi mumabhuku maduku, dzinoiswa pamotokari dzavo: BMW, Ford, Mazda, Infiniti, Hyundai, Mercedes-Benz uye General Motors.

Kushandiswa kweFSI injini kunoderedza zvakanyanya kuburitsa kunokuvadza kubva kumotokari uye kunoderedza kushandiswa kwemafuta ne10-15%.

Musiyano mukuru kubva kumagadzirirwo apfuura

Chinhu chakakosha chinosiyanisa cheFSI kuvepo kwemaviri anoteedzana masisitimu emafuta anopa peturu. Yekutanga ndeye yakaderera-kumanikidza inogara ichitenderera mafuta ekudzoka system inobatanidza gasi tangi, circulation pombi, strainer, control sensor, uye peturu yekugovera pombi kune yechipiri system.

Dunhu rechipiri rinopa mafuta kune injector yeatomization uye kugovera kumasilinda ekupisa uye, semugumisiro, basa remagetsi.

Nheyo yekushanda kwema contours

Basa rekutanga rekutenderera redunhu nderekupa mafuta kune yechipiri. Inopa kutenderera kunogara kutenderera kwemafuta pakati petangi remafuta uye peturu jekiseni mudziyo, iyo inoiswa seyakapfapfaidza nozzle.

Kuchengetedza iyo inogara ichitenderera modhi inopiwa nepombi iri mugasi tangi. Iyo yakasimwa sensor inogara ichitarisa chiyero chekumanikidza mudunhu uye inoendesa ruzivo urwu kune yemagetsi unit, iyo, kana zvichidikanwa, inogona kushandura kushanda kwepombi yekugadzika kupihwa kwepeturu kudunhu rechipiri.

Basa redunhu rechipiri nderekuona kupihwa kwehuwandu hunodiwa hwemafuta eatomu mumakamuri ekupisa ejini.

Kuti aite izvi, zvinosanganisira:

• plunger-mhando yekupa pombi yekugadzira inodiwa mafuta ekumanikidza kana yapihwa kumuromo;
• regulator yakaiswa mupombi kuti ive nechokwadi chekuti metered mafuta anowanikwa;
• kudzvinyirira shanduko yekudzora sensor;
• nozzle yekupfapfaidza peturu panguva yejekiseni;
• kugovera rampu;
• vharafu yekuchengetedza, kuchengetedza zvinhu zvehurongwa.

Kurongeka kwebasa rezvinhu zvese zvinopihwa neyakakosha yemagetsi control kifaa kuburikidza nema actuators. Kuti uwane musanganiswa wepamusoro-soro unopisa, mita yekuyerera kwemhepo, dhiraivha yekuyerera kwemhepo uye madhiraivha ekudzora emhepo anoiswa. Kudzora zvigadzirwa zvemagetsi zvinopa chiyero chehuwandu hweatomu yemafuta uye mhepo inodiwa pakupisa kwayo, inotsanangurwa nechirongwa.

Nenzira, pane yedu vodi.su portal, pane chinyorwa chaunodzidza mashandisiro ekukurumidza injini kutanga.

Kugadzirisa nheyo

Mukushanda kweinjini yeFSI, kune nzira nhatu dzekugadzira musanganiswa unopisa, zvichienderana nekuremerwa kweinjini:

• homogeneous stoichiometric, yakagadzirirwa kushanda kwechikwata chemagetsi pakumhanya kukuru uye mitoro inorema;
• homogeneous homogeneous, yekushanda kwemotokari mune zvepakati modes;
• akaturikidzana, kuitira kushanda kweinjini panguva yepakati uye yakaderera kumhanya.

Muchiitiko chekutanga, nzvimbo ye throttle air damper inotarirwa zvichienderana nenzvimbo yeaccelerator, madhamu ekutora akazaruka zvakakwana, uye jekiseni remafuta rinoitika pane imwe neimwe injini. Iyo coefficient yemhepo yakawandisa yekupisa mafuta yakaenzana neimwe uye yakanyanya kupisa kupisa kunowanikwa mune iyi nzira yekushanda.

Pakati peinjini inomhanya, iyo throttle valve inovhura zvizere uye mavharuvhu ekupinda anovharwa, semhedzisiro, iyo yakawandisa mhepo chiyero inochengetwa pa1,5 uye kusvika 25% yemagasi ekupera anogona kusanganiswa mumusanganiswa wemafuta kuti ushande zvakanaka.

Mu stratified carburetion, mapikisi ekutora akavharwa, uye throttle valve yakavharwa uye yakavhurwa zvichienderana nemutoro uri pajini. Iyo coefficient yemhepo yakawandisa iri pakati pe1,5 kusvika 3,0. Mhepo yakasara yakawandisa munyaya iyi inobata basa rekushanda kwekushisa insulator.

Sezvauri kuona, musimboti wekushanda kweinjini yeFSI yakavakirwa pakuchinja huwandu hwemhepo inopihwa kugadzirira musanganiswa unopisa, chero mafuta akapihwa zvakananga kukamuri yekupisa kuburikidza neaspray nozzle. Iyo mafuta uye mhepo inopa inodzorwa ne sensors, actuators uye yemagetsi injini control unit.
