Mhedzisiro yeDouble Injector pane Combustion process mu396 Series Diesel Engine (chikamu 3)

Modhi yekupisa

Hunhu humiro hweiyo 396 yakatevedzana dizeli injini ine flat-top convex basin combustion chamber inoratidzwa muTebhurari 1. Iyo geometric modhi inodhirowewa neProE software, mesh division inopedzwa neHypermesh software, uye ipapo mesh inogadziriswa uye yakavharidzirwa ne. iyo AVL MOTO. Iyo dynamic mesh yakagadzirirwa kuverenga uye post-processing kuongororwa. Sezvo mafambiro emhepo ari mucylinder ari asymmetrical uye ane mhedzisiro pakugoverwa kwenzvimbo yemafuta ekupfapfaidza uyezve pakupisa maitiro, modhi inotangwa yekamuri yese yekupisa. Kune 56050 uye 158900 mesh maseru paTDC (yepamusoro akafa pakati) uye BDC (pazasi akafa pakati) zvichiteerana, uye modhi yekamuri yekupisa paTDC inoratidzwa muMufananidzo 1.9.

Iwo makuru ma paramita e5-gomba uye 8-gomba majekiseni uye 4-gomba dual-injector anoratidzwa muTebhurari 2, uye majekiseni ane majekiseni akasiyana-siyana ane huwandu hwakafanana hunoshanda kuyerera kwechikamu chechikamu chechikamu. Kugoverwa kwezvimedu zvekupfapfaidza muhumburumbira mushure mejekiseni yemafuta ye5 ° CA inoratidzwa muMufananidzo 2. Iyo eddy ikozvino chiyero mucylinder yakaiswa ku 2.9, kufamba kwemhepo mucylinder is asymmetric nekuda kwenzvimbo yevhavha inopinza, uye mafuta. pfapfaidzo inokanganiswawo nekufamba kwemhepo.10.

Iyo kemikari reaction dynamics calculation inoitwa nedhiziri yakajairika chikamu chekutakura modhi yeMOTO, uye iyo huru yekuverenga modhi sarudzo inoratidzwa muTafura 3. MuKHRT spray breakup model, kukosha kweCoefficient C2 kunoiswa ku12.

3. Simulation mhedzisiro uye kuongororwa Mufananidzo 3, Mufananidzo 4 uye Mufananidzo 5 zvichiteerana kuratidza kuenzanisa uye kuongororwa kwekumanikidzwa muhumburumbira, kupisa kuburitsa mwero, avhareji tembiricha mu cylinder, yakaunganidzwa kupisa kuburitswa uye NO uwandu chikamu kana 5-gomba uye 8-gomba majekiseni. uye 4-gomba mbiri-injector inogamuchirwa.
