Ọdịmma dị elu Diesel Rail / Mmanụ Injector Nozzle DLLA145SM012

Injector mmanụ bụ akụkụ bụ isi nke sistemu ịgba mmanụ mmanụ, yana ọnọdụ ọrụ ya na-enwe mmetụta dị ukwuu na arụ ọrụ nkịtị nke injin. N'ihi na injector na-arụ ọrụ na gburugburu ebe obibi dị nnọọ njọ, ekpughere ozugbo na elu okpomọkụ na nnukwu nrụgide combustion

N'ime ụlọ ahụ, ihe nkiri mmanụ dị na nozzle na-adịkarị mfe oxidation, polymerization na mmeghachi omume ndị ọzọ, na-ebute mkpokọta carbon na nozzle. Nnyocha ndị dị adị achọpụtala na ntinye carbon n'ime oghere injector ga-eduga n'ịba ụba nke ịgbanye mmanụ ọkụ, atomization na-adịghị mma na àgwà ọkụ ọkụ, yana ibelata ike engine na akụ na ụba. Zhou Jianwei et al. mụọ banyere carbon deposition àgwà nke injector nke kpọmkwem injection petrol engine wee chọpụta na carbon deposition ogo nke ọ bụla oghere nke injector dị iche iche, na carbon deposition gosiri abụọ morphologies: akọrọ siri ike na mmiri ire ụtọ. Liaquat et al. nyochara ntinye carbon n'ime oghere jet nke otu igwe mmanụ dizel nke otu cylinder diesel ka anwalechara awa 250, wee chọpụta na a na-ekesa ntinye carbon n'elu nke injector, nke nwere C, O, Zn na S..

Ngwakọta ihe. Barbour et al. nyochaa njirimara morphology nke nkwụnye carbon carbon n'ime oghere mgbe ị gbuchara oghere injector nke ụfọdụ engine diesel mgbe ọ rụchara ọrụ maka awa 60, wee chọpụta na e nwere akwa mkpuchi carbon nke dị n'ime oghere injector nke nkwụnye carbon.

Kumagai et al. mụọ mmetụta Zn element na mmanụ mmanụ nke otu cylinder diesel engine na carbon deposition na jet hole, wee chọpụta na ma Zn element ọ dị n'ime ma ọ bụ na e nwere, e nwere ihe carbon ntinye n'akụkụ mpụta nke jet oghere karịa. n'akụkụ mbata, ma mgbe mmanụ nwere Zn element, carbon nkwụnye ụmụ irighiri n'ime oghere dị nta na otu na udidi.
