Na obi nke dizel engine, na mmanụ ụgbọala injection usoro ekere òkè dị mkpa roles.Through pressurizing na ịgbanye mmanụ ụgbọala, usoro agha ya n'ime ikuku na e abịakọrọ na elu nsogbu na combustion chamber.It mee nke fuel injection mgbapụta , elu-mgbali ọjà, injection nozulu, ndepụta mgbapụta na mmanụ ụgbọala iyo, nke ọ bụla mmiri nwere ya ọrụ a systems.Like fuel injection mgbapụta pressurises mmanụ ụgbọala elu pressure.While elu-mgbali anwụrụ izipu mmanụ ụgbọala na injection nozulu onye ọrụ bụ ka injector mmanụ ọkụ n'ime cylinder.For oriri mgbapụta, ọ na eme nzuzu mmanụ ụgbọala si mmanụ ụgbọala tank, ụfọdụ nke na-enwe a mmanụ ụgbọala sedimentor na ala nke nyo ikewapụ mmiri ọdịnaya site na fuel.Finally mmanụ nyo filtrates mmanụ ọkụ .Ihe nile nke ha na-arụ ọrụ ọnụ anya ka mmanụ dizel injection usoro arụmọrụ well.Today, ndị ọkachamara na-emepụta maka fuel injection akụkụ,China Balin Parts Plant  ga-ewebata isi 4 ọrụ nke mmanụ dizel injection usoro. 

1.Feeding mmanụ

Mgbapụta ọcha dị ka ndị cylinder na plunger na-wuru n'ime ọgwụ mgbapụta ahụ. The mmanụ ụgbọala na-abịakọrọ na elu nsogbu mgbe cam lifts plunger, na-ahụ zitere ka injector. 

2.Adjusting mmanụ ụgbọala ibu

Na dizel engines na oriri nke ikuku bụ fọrọ nke nta mgbe nile, irrespective nke n'usoro ọsọ na ibu. Ọ bụrụ na ndị ọgwụ ibu gbanwere na engine ọsọ na ọgwụ oge bụ mgbe niile, na mmepụta na mmanụ ụgbọala oriri mgbanwe. Ebe ọ bụ na engine mmepụta bụ fọrọ nke nta proportional na injection buru ibu, nke a na-gbanwere ome osooso pedal. 

3.Adjusting injection oge

Mgbanye oge bụ oge n'etiti mgbe mgbe mmanụ ụgbọala na-agbara, amụnyewo na combusted na mgbe kacha combustion nsogbu na-ruru. Dị ka oge a nke oge bụ fọrọ nke nta mgbe nile, irrespective nke engine ọsọ, a ngụ oge na-eji aka ịgbanwe ma na-agbanwe injection oge - eme kacha combustion na-enweta. 

4.Atomising mmanụ

Mgbe ọgwụ mgbapụta pressurize na mmanụ a na-ahụ atomised si injection nozzle.Then mmanụ ụgbọala ga-agwakọta ya na ikuku kpamkpam, reasulting na mgbanye improved.This ga-zuru ezu combustion.
