GDI ọ bụ ọdịnihu?

Otu n'ime ohere iji melite arụmọrụ nke engine bụ ịkwalite usoro nke combustion nke ngwakọta na cylinders.

Otu n'ime ntụziaka nke imeziwanye arụmọrụ nke engine combustion n'ime ime bụ ọrụ na-eme ka usoro nchịkọta ọkụ ọkụ dị na cylinders dịkwuo mma.

Ụzọ iji nweta ihe mgbaru ọsọ a bụ nkwadebe ziri ezi nke ngwakọta combustible site na iji injection mmanụ ụgbọala kpọmkwem n'ime cylinders n'okpuru nnukwu nrụgide GDI / mmanụ ụgbọala Direct Injection /. Uru a na-apụghị ịgbagha agbagha nke injin a bụ pasent 20 dị ala nke oriri mmanụ.

A na-enweta oriri mmanụ ala site n'ịkụ ngwakọta na-adịghị ala ala. Mgbanye nke ngwakọta dị otú ahụ ga-ekwe omume n'ihi ọdịdị pụrụ iche nke ụlọ combustion. A na-emepụta mpaghara nke ngwakọta bara ụba, ngwa ngwa ngwa ngwa n'akụkụ plọg ọkụ, nke ọkụ na-esi na ya na-agbasa na mpaghara nke ngwakọta na-adabere na ya. Mgbe achọrọ ike zuru oke, injin ahụ na-ere ngwakọta stoichiometric ọkụ.

E jiri ya tụnyere igwe eji eme ihe, igwe GDI nwere uru ọzọ. Ọ bụ mbelata ikuku nke carbon dioxide na obere ntinye nke nitrogen oxides n'oge ọrụ injin na ibu akụkụ.
