Ihe nlereanya geometric nke ụlọ combustion na TDC (n'elu nwụrụ anwụ etiti) bụ nke ProE na-ese, dị ka egosiri na Figure 1, echekwara ya dị ka faịlụ usoro STEP. A na-ebubata ụdị geometric n'ime ngwa ngwa mesh hyper maka nkewa ntupu ma chekwaa ya dị ka faịlụ ntupu n'ụdị NAS. A na-ebuba faịlụ ntupu n'ime ngwa AVL FIRE maka nyocha ntupu, nchacha, ntọala ntupu siri ike, nhọrọ nke obere ụdị na ntọala paramita [6].

Injector nke nwere oghere 4 nke injin dizel F186 nakweere nwere oghere 4 kesara nke ọma, mana ntụzịaka ntụ ntụ ekwekọghị n'akụkụ akụkụ cylinder. Ebe etiti nke olulu nke ω combustion chamber nwere nkwụsị nke 3 mm site na etiti piston, na mmegharị ikuku na cylinder nwere mmetụta dị iche iche na mmanụ ọkụ nke oghere ọ bụla, ya mere a na-anabata ụlọ ọkụ ọkụ dum. A na-ezobe ntupu ahụ na mpaghara dị nso na oghere na ókèala ahụ, a na-egosikwa ụdị ntupu na TDC na Figure 2. Enwere 140448 na 343488 mesh cell na TDC na BDC (ala nwụrụ anwụ etiti) n'otu n'otu.

E gosipụtara paramita nke engine dizel na tebụl 1. Ọnọdụ na ntọala ntụziaka nke injector bụ ndị a: X-coordinate (0.003 m), Y-coordinate (-0.003 m), Z-Coordinate (0 m), X -ntụziaka (0.007), Y-direction (0.0397), Z-direction (0). E gosipụtara ọnọdụ nke oghere nke ọ bụla na Tebụl 2. A na-eme ka ọnụ ọgụgụ injection dị otu na nha nha nha nha nke oghere ọ bụla dị ka ntọala injection, na ọnụego injection gosipụtara na Figure 3. Ụdị ihe eji ebu mmanụ dizel bụ ọkọlọtọ. A na-eji maka mgbako mmeghachi omume kemịkalụ, yana usoro ngụkọ metụtara na-egosi na tebụl 3 [7, 8].
