Diesel Injector Fuel Injector A2c59515264 Siemens ford Ranger 3.0L Engine

Simulation Chidzidzo pamusoro peKukanganisa Kwekusaenzana Kwemafuta Jekiseni reGomba rega rega reDiesel Injini Injector pane Iyo Combustion process.(CHIKAMU 3)

2 Combustion modhi

Iyo geometric modhi yekamuri yekupisa paTDC (yepamusoro yakafa centre) inodhonzwa neProE software, sezvakaratidzwa muFigure 1, uye inochengetwa se STEP fomati faira.Iyo geometric modhi inounzwa kune hyper mesh software ye mesh division uye inochengetwa semesh faira muchimiro cheNAS.Iyo mesh faira inounzwa muAVL FIRE software yekuongorora mesh, kunatsiridza, ine simba mesh kuseta, kusarudzwa kwemadiki-modhi uye parameter kumisikidza [6].

Iyo 4-gomba jekiseni yakagamuchirwa neF186 injini yedhiziri ine 4 maburi akaenzana-akaparadzirwa, asi jekiseni nzira haienderane nekona yehumburumbira chikamu.Pakati pegomba re ω combustion chamber ine 3 mm inobvisa kubva pakati pepiston, uye kufamba kwemhepo mucylinder kune zvakasiyana-siyana pamafuta emafuta egomba rega rega, saka iyo yose yekupisa kamuri yekuenzanisira inogamuchirwa.Iyo mesh yakavharidzirwa munzvimbo iri padyo negomba uye muganhu, uye mesh modhi paTDC inoratidzwa muMufananidzo 2. Kune 140448 uye 343488 mesh masero paTDC neBDC (pazasi akafa pakati) zvichiteerana.

Izvo zviyero zvejini yedhiziri zvinoratidzwa muTable 1. Nzvimbo uye kutungamira marongero ejekiseni ndeaya: X-coordinate (0.003 m), Y-coordinate (-0.003 m), Z-coordinate (0 m), X -direction (0.007), Y-direction (0.0397), Z-direction (0).Mamiriro enzvimbo yegomba rimwe nerimwe anoratidzwa muTebhurari 2. The yunifomu jekiseni mwero uye kuyerwa kusaenzana jekiseni mwero wegomba rimwe nerimwe anoitwa sezvo jekiseni kugadzika, uye jekiseni mwero inoratidzwa mufananidzo 3. Yakajairwa chikamu chikamu chekutakura modhi yemafuta edhiziri ndeye. inoshandiswa pamakemikari reaction kinetics calculation, uye muenzaniso wekuverenga unobatanidzwa unoratidzwa muTebhu 3 [7, 8].
