Mmetụta nke dayameta nozzle, nrụgide injection na ọnọdụ okpomọkụ na njirimara ịgba na mmanụ dizel (akụkụ 1)
1. Okwu mmalite
Mmanụ a na-agbanye n'ime ụlọ dị mkpa maka engine diesel n'ihi na ọ na-emetụta arụmọrụ na ikuku. N'oge a na-agba ọkụ, ihe na-agba mmiri bụ naanị iwebata mmiri mmiri n'ime ikuku gas site na mmiri mmiri nke na mmiri mmiri ahụ, site na mmekọrịta ya na gas gbara ya gburugburu na site na nkwụsi ike nke ya, na-agbaji n'ime ụmụ irighiri mmiri [1]. Amara njirimara ịgbasa ka ọ na-emetụta oke ọkụ na usoro mgbanyụ ọkụ n'ime igwe mmanụ dizel. Site n'ịkwalite njirimara ịgba, enwere ike ibelata ihe na-esi na injin dizel nke bụ NOx na PM [2-4]. Nnyocha n'ime njirimara sprays mmanụ dizel gbadoro ụkwụ na mmetụta nke njirimara ịgba na arụmọrụ engine dị ka ntinye n'ọnụ ịgbasa, ogologo nkwụsịtụ na nha droplet na ikesa ọsọ ọsọ [5].Mgbanye ntụtụ nwere mmetụta dị ukwuu na ntinye mmiri mmiri [6]. ].

N'ikwekọ na nrụgide injection, ịgba ahụ na-abanye ngwa ngwa na nrụgide injection dị elu [8]. Ogologo mgbawa ahụ na-egosipụta ebe nkwụsịtụ, ebe ịgbasa na-agbanwe site na mpaghara mmiri mmiri (oke mmiri mmiri, ma ọ bụ njikọ jikọrọ ọnụ na ụmụ irighiri mmiri), gaa n'usoro nchịkwa nke ụmụ irighiri mmiri [9]. Mgbe mgbawa nke kọlụm mmiri mmiri na-apụta na nozzle, ụmụ irighiri mmiri na-emepụta nwere ike gbasaa n'ime obere ka ha na-abanye na gas gbara ya gburugburu [10].
