Variable geometry kutora akawanda

Kuti uite basa rakakwana, kuwanda kwemotokari kunotora kunofanirwa kuve nejeometry chaiyo kuti ienderane nekumhanya kweinjini. Nechikonzero ichi, iyo yekare dhizaini inongovimbisa kuti masilinda akaremerwa zvakafanira mune shoma renji yekumhanyisa injini. Kuve nechokwadi chekuti mweya wakakwana unopihwa kukamuri yekupisa chero kumhanya, inopinza manifold geometry shanduko system inoshandiswa.

Mashandiro Eiyo Yakasiyana Geometry Manifold System Inoshanda

Mukuita, kuchinjwa kwehuwandu hwekudya kunogona kuitwa nenzira mbiri: nekushandura nzvimbo ye-cross-sectional uye nekushandura urefu hwayo. Nzira idzi dzinogona kushandiswa dzimwechete kana dzakasanganiswa.

Hunhu hwehuwandu hwekutora hurefu hwakasiyana

Variable Length Intake Manifold - Iyi tekinoroji inoshandiswa pamotokari dzepeturu nedhiziri, kusasanganisa masisitimu akachajiswa. Nheyo yekugadzira iyi ndeiyi inotevera:

• Pamutoro wakaderera painjini, mweya unopinda kuburikidza nebazi remuunganidzi rakareba.
• Pakumhanya kwejinjini - pamwe nebazi pfupi remuunganidzi.
• Nzira yekushanda inoshandurwa ne injini ECU kuburikidza neactuator inodzora valve uye nokudaro inotungamirira mhepo nenzira pfupi kana yakareba.

Iyo yakasiyana-siyana yehurefu yekutora manifold yakavakirwa pakuita kwe resonant boost uye inopa jekiseni rakasimba remhepo mukamuri yekupisa. Izvi zvinoitwa nenzira inotevera:

• Imwe mhepo inoramba iri mumanifold mushure mekunge mavharuvhu ese ekupinza avharwa.
• Iyo oscillation yemhepo yakasara mune yakawanda inoenzanirana nehurefu hwehuwandu hwekupinza uye kumhanya kweinjini.
• Kana kudengenyeka kunosvika resonance, high pressure inogadzirwa.
• Mhepo yakamanikidzwa inopihwa kana vharuvhu yekupinda yakavhurwa.

Injini dzepamusoro hadzishandise rudzi urwu rwekudya kwakawanda nekuti hapana chikonzero chekugadzira resonant air compression. Jekiseni mumasisitimu akadaro anoitwa uchishandisa yakaiswa turbocharger.

Hunhu hwehuwandu hwekutora nechikamu chinoshanduka

Muindasitiri yemotokari, kudzoreredza manifold resizing kunoshandiswa pamotokari dzepeturu nedhiziri, kusanganisira masisitimu akanyanya. Iyo diki muchinjiko-chikamu chepombi iyo mweya unopihwa, iyo yakakura kuyerera, uye nokudaro kusanganiswa kwemhepo nemafuta. Mune iyi sisitimu, silinda imwe neimwe ine madoko maviri ekutora, imwe neimwe iine vharuvhu yayo yekudya. Imwe yenzira mbiri ine damper. Iyi yekutora manifold geometry shanduko system inofambiswa nemagetsi mota kana vacuum regulator. Iyo dhizaini nheyo ndeiyi inotevera:

• Kana injini ichimhanya nekumhanya kwakaderera, madhamu ari munzvimbo yakavharwa.
• Kana vharuvhu yekupinda yakavhurika, musanganiswa wemafuta emhepo unopinda muhumburumbira kuburikidza nechiteshi chimwe chete.
• Sezvo kuyerera kwemhepo kuchipfuura nemugero, inopinda mukamuri mune inotenderera fashoni kuti ive nechokwadi chekusanganisa zvirinani nemafuta.
• Apo injini iri kushanda nekumhanya kukuru, madhamu anozaruka uye musanganiswa wemhepo-mafuta unoyerera kuburikidza nematanho maviri, kuwedzera injini simba.

Ndezvipi zvirongwa zvekushandura geometry zvinoshandiswa nevagadziri

Muindasitiri yemotokari yepasirese, iyo yekutora manifold geometry system inoshandiswa nevazhinji vagadziri vanotaura nezve tekinoroji nemazita avo akasiyana. Naizvozvo, kureba kwakasiyana kwekutora akawanda madhizaini anogona kutsanangurwa seanotevera:

• Ford Zita rehurongwa ndiDual-Stage Intake;
• BMW Zita rehurongwa ndiro Differential Variable Air Intake;
• Mazda.  Zita rehurongwa ndiVICS kana VRIS.

Iyo meshini yekushandura chikamu chemuchinjiko weyakawanda manifold inogona kuwanikwa se:

• Ford Zita rehurongwa iIMRC kana CMCV;
• Opel. Zita rehurongwa ndiTwin Port;
• Toyota. Zita rehurongwa ndiro Variable Intake System;
• Volvo. Iro zita rehurongwa ndiVariable Induction System.

Iko kushandiswa kweiyo geometry shanduko system, zvisinei nekushanduka kwehurefu kana kuyambuka-chikamu cheiyo yakawanda yekudyara, inovandudza mashandiro emotokari, inoita kuti ive yakanyanya hupfumi uye inoderedza kuwanda kwezvinhu zvine chepfu mumagasi emhepo.
