Musiyano pakati pe-single-point uye multi-point jekiseni

Nepo mota dzese dzemazuvano dzichishandisa jekiseni remultipoint, mota zhinji dzechikuru (dzisati dzatanga 90s) dzinobatsirwa kubva kune singlepoint jekiseni.

Ndeupi musiyano uye nei?

Ngatitangei kubva pakutanga ... Yekutanga mafuta system yakashanda necarburetor umo mafuta akabuda ari muchimiro chemhute yakasanganiswa nemhepo (pawakanyanya kudzvanya pedal, iyo yakawedzera kuvhurwa. Maiwe, maitiro aya akange asina kunyatso Zvino kwakauya jekiseni (yekutanga poindi imwe chete ), iyo panguva ino yaisanganisira kubaya mafuta (yaidzorwa nemagetsi) yakananga muchikamu chekudya (kana manifold), nokudaro kuvandudza kushanda zvakanaka. sarudza jekiseni rimwechete.Pakupedzisira, zvakaonekwa kuti zvingava zvakatonyanya hupfumi kupinza mafuta padhuze nepazvinogona kukamuri yekupisa, kukwanisa kudzora, silinda, silinda, dhizi rakatumirwa: ndipo pakabuda jekiseni remapoinzi akawanda (zvakananga kana zvisina kunanga: dzvanya ona pano kune Rens. musiyano.) Iri jekiseni remapoinzi akawanda rakazovandudzwazve kuita hurongwa hunonzi "common rail" (tinya pano kuti uzive) kana kunyange jekiseni repombi reVolkswagen (kubvira rakasiiwa).

Iyo imwe poindi yakabvumira kuchengetedza mafuta nekunyatso kudzora huwandu hwemafuta anounzwa kune yakawanda yekudya (iyo carburetor inoita izvi zvishoma "zvakaoma"). Multi-point ingori shanduko yeimwe-poindi sezvo isu tichishandisa nzira imwechete nekubatanidza jekiseni muhumburumbira yega yega (saka kugadzira kunodhura ...). Izvi zvinoita kuti dosing iwedzere kunyatsojeka, zvichibatsira kudzivirira kupera kwemafuta. Pakupedzisira, njanji yakajairwa (yakaiswa pakati pepombi nemajekiseni, ichiita sekumanikidza kuunganidza) yakawedzera kushanda zvakanaka.

SINGLE-POINT jekiseni: jekiseni rimwe rinounza mafuta kune akawanda. Iyo yakawanda yekuwandisa yakasimbiswa mutsvuku, asi isu hatisi kunyanya kufarira nezvayo pano.

MULTIPOINT jekiseni: jekiseni rimwe chete pasirinda. Iyi jekiseni yakananga (ini ndinogona zvakare kuita isina kunanga jekiseni kuenzanisira izvi: ona chinyorwa chakabatana pane iyi chinongedzo chakapihwa mune iwo mavara ari pamusoro)

Yakatsanangurwa naWanu1966: Main Site Nhengo

jekiseni multipoint : Mhepo inoiswa metered nebhokisi rakaiswa mune yakawanda yekudyira. Iyo mafuta inogadziriswa uchishandisa metering mudziyo, iyo damper iyo inogadziriswa nekufambisa mhepo inoyerera mita inowanikwa mune yakawanda yekudyara. Iyo peturu inopihwa kune iyo metering unit kubva kune yemagetsi pombi kuburikidza neanomanikidza regulator. Iwo majekiseni anoramba achipa mafuta, kudzvinyirira uye kuyerera kweyero iyo inotarirwa nemhepo yekuyerera kwemhepo uye yayo yakazara kumanikidza.

Magetsi jekiseni poindi imwe chete : Izwi rokuti "single-point" rinoreva kuti kune jekiseni rimwe chete muhurongwa, kusiyana ne-multi-point system, iyo ine injector imwe pa cylinder.

Single-point jekiseni rine throttle body iri pamberi peyekupinza manifold (manifold) uye painoiswa jekiseni.

Kuyerera kwemweya kunoyerwa ne potentiometer yakabatana nevhavha yeprottle uye negeji yekumanikidza yakaiswa pombi. Ruzivo urwu rwunotumirwa kukombuta, iyo inoratidza injini kumhanya, kunwa mweya tembiricha, okisijeni zvemukati mune yekuzadza magasi uye tembiricha yemvura.

Iyo komputa inoongorora iyi ruzivo uye inoendesa yekudzora voltage kune yemagetsi injekiseni, kutanga, nguva uye kupera kwejekiseni iyo zvinoenderana nemipimo yekuisa.

Wese makomendi uye maitiro

Kuverenga dhatasheet raSuzuki, ndinoona zvichiratidza kune maviri epeturu injini: jekiseni rema multipoint yeimwe uye yakananga jekiseni kune imwe. Chekupedzisira, kana ndikanyatsonzwisisa, zviri nezvechinhu chimwe chete ichocho here? Ndatenda nechinyorwa.

Il J. 3 reaction (s) kune ichi chirevo:

• Admin SITE MUDZIMAI (2020-06-08 10:42:08): akawanda-poindi zvinoreva akawanda mabhureki. Saka inogona kunanga kana kunanga.

  Asi nekokorodzano, isu tinotaura nezve multipoint kana isina kunangana (zvinopesana ne monopoint), nekuti nejekiseni yakanangana, inogona chete kuve multipoint.

  Muchidimbu, multipoint = isina kunangana nemajekiseni mazhinji muhubhu, uye yakananga = yakananga ...

• GOSEKPA (2020-08-24 20:40:02): Pane kupesana mutsamba yako.

  iwe unoti "" negungano, tinotaura nezve-multi-point kana isina kunanga (kusiyana ne-single-point) nekuti nejekiseni rakananga rinogona kungova mapoinzi akawanda "." Kazhinji mutsara wakatwasuka, unogona kuva multipoint chete.

• Acb (2021-06-08 23:31:01): Ini hapana chandinonzwisisa, chii chaunofanira kumagumo ??

Iwe unonzwa wakasungirirwa kune iwe pachako here?
