Mhedzisiro yeDouble Injector pane Combustion process mu396 Series Diesel Engine (chikamu 5)

Kana iyo 8-gomba jekiseni inogamuchirwa, kukanganisa kweiyo yakaderedzwa yekupinda chinhambwe pakupisa inowedzerwa, iyo yakazara mafuta yekugovera nzvimbo uye pre-yakasanganiswa inopisa inoderedzwa, uye kupisa kwekupararira kunodzikiswa, nekudaro kuita kuti kupisa kuve kusina kukwana uye. kupisa kwekushisa kuderera. Mushure mokunge 4-hole mbiri-injector yakagamuchirwa, sezvo majekiseni maviri akaparadzaniswa neimwe chinhambwe, nzvimbo yekugovera nzvimbo yemafuta inowedzera, uye kusanganiswa kwepakati pakati pemafuta spray uye mhepo mu cylinder inowedzera.

Kunyangwe nhambwe inopinda ichiri ipfupi uye kupisa kwakambosanganiswa kuchiri kushoma pane iyo ye5-gomba jekiseni, yakaunganidzwa kupisa kuburitswa kwakaenzana neiyo ye5-hole jekiseni nekuti mweya uri mucylinder unoshandiswa zvizere, kupisa. nguva yekupararira kwekupisa kwakareba zvishoma uye kupisa kunowedzera kuzara. Mufananidzo 5 unoratidza kuti, kana 8-hole injector inogamuchirwa, kupisa hakuna kukwana, kupisa kwemhepo uye kupisa kwevhareji mu cylinder uye NO emission yakaderera. Kana iyo 4- hole dual-injector yagamuchirwa, iyo NO emission inenge 60% yeiyo ye5-hole jekiseni nekuda kwekudzika kwakanyanya kwekupisa tembiricha.

4 Simulation mhedzisiro uye kuongororwa kwekupfupisa jekiseni nguva ye4-gomba mbiri-injector

Pasi pemamiriro ekuti nguva yejekiseni uye nzvimbo inobudirira yekuyerera haina kuchinjwa, kupisa kwekushisa kunoderedzwa kana kuchinja 5-hole injector kune 8-hole injector. Zvisinei, kana 4-hole dual-injector ikagamuchirwa, kupisa kwekushisa kunochengetwa kwakafanana neiyo ye5-hole jekiseni. Kana kudzvanywa kwejekiseni kuchiwedzerwa, nguva yejekiseni inopfupiswa uye chinhambwe chinopinda chemafuta danda chinowedzerwa, kusanganiswa kwemafuta nemhepo kunowedzerwa uye maitiro ekupisa anovandudzwa. Mufananidzo 6, Mufananidzo 7 uye Figure 8 zvichiteerana kuratidza kudzvanywa muhumburumbira, kupisa kuburitsa mwero, avhareji tembiricha muhumburumbira, yakaunganidzwa kupisa kuburitswa uye HAPANA chidimbu chidimbu kana jekiseni angle ye4-gomba mbiri-injector iri 26.84 ° CA, 22 ° CA uye 20 ° CA.
