The dizel engine obi bụ fuel injection mgbapụta, deliverying mmanụ ụgbọala ịnọgide na-enwe a n'afọ iri na ụma ma ọ bụ oge nke na-eme ka ihe ịga nke ọma na-agba ọsọ nke engine.At n'otu oge ahụ, ọ na-ịchịkwa mmanụ ụgbọala ibu inweta ike required.While na mmanụ ụgbọala engine , na-agbanye mgbapụta ahụ ga-arụ bụ na trotul na mgbanye system.So ma ọ bụrụ na e ọ bụla probem na mmanụ ụgbọala mgbapụta, ọ dị mkpa iji chọpụta mkpakọ, mmanụ ụgbọala, na spark.Because e nweghị mgbanye usoro ke dizel engine.Comparing ka mmanụ ụgbọala engine, na dizel engine nwere uru nke a kpọmkwem n'ihi mma mmanụ ụgbọala injection.Today China Balin Parts Plant, a zuru ụwa ọnụ emeputa nkịtị okporo ígwè akụkụ & dizel injection akụkụ, ga-egosi gị otú ị na-agbanye mgbapụta ọrụ. Inline-ọgwụ (jerk) nfuli Na 1890s mbụ nfuli iji plungers ịmanye metered mmanụ ụgbọala na combustion ulo bu developed.Later na 1927, uka-emepụta helix-achịkwa inline mgbapụta na-ẹkenam site BOSCH.The nfuli, mgbe ụfọdụ, a na-akpọ jerk nfuli, anya dị ka Bosch P7100 (P-mgbapụta) on '94 na '98 Dodge Ram 5.9L Cummins engines.Meanwhile ha rụrụ site iche iche mgbapụta na plunger nkeji ejikọrọ inline, onye kwa cylinder.They na-arụ ọrụ site na a cam, nke bụ mechanically jikọọ na engine.Although ha na-adịghị na sophistication nke electronically-achịkwa usoro, nfuli ka nwere ọrụ nke ịdị iche iche timing.Inline injection nfuli anya dị ka Obere inline engines.It nye 3,000-5,000 psi nke injection mgbali maka mbụ Obere inline injection nfuli mgbe 18,000 psi nrụgide ihe ọhụrụ n'anya, bosch P7100 nke anyị nwere ike ịhụ na '94 ka '981/2 Cummins engines. Nkesa (Rotary) Ọgwụ nfuli E nwere nanị otu mmanụ ụgbọala-metering plunger na nkesa injection pump.Similar na nkesa na-arụ ọrụ ụkpụrụ na a mmanụ ụgbọala engine, na haịdrọlik e jikọtara ya na dị iche iche ụgbọ mmiri na nkesa isi site a spinning rotor.This rotary injection mgbapụta nwere uru na niile gbaa nke mmanụ ụgbọala bụ kpọmkwem otu bụ nke na-a nta n'ozuzu package.Comparing na inline nfuli, ya ọzọ uru bụ na o nwere obere na-akpali akpali parts.Let anyị n'ibu rotary nfuli (Stanadyne DB2 na bosch VE ) maka example.The mgbali 6.700 psi na-emepụta site Stanadyne DB2 na 17,000 psi site bosch VE. Ihe atụ ọzọ bụ ihe electronic rotary mgbapụta ka Bosch VP44.It ike na-23,000 psi pressure.Even atụnyere ọhụrụ nkịtị-okporo ígwè CP3 nfuli, anyị nwekwara ike ikwu na ọ bụ smartest pump.Because ọ bụghị naanị ike ike nsogbu, ma na-ịchịkwa oge na nke ukwu nke mmanụ ụgbọala anapụta ndị engine. Common-Okporo ígwè Ọgwụ na nkịtị-okporo ígwè mmanụ ụgbọala ogwu ogbugba, mgbapụta enweghị ọtụtụ ikike ikpebi mgbe mmanụ ụgbọala ya pressurizes ego n'anya nye na ihe quantity.For atụ, CP3 mgbapụta enweta mmanụ ụgbọala si mmanụ ụgbọala tank.Then ọ na-eji radial -piston imewe ntọt mgbali immensely.After na, nkịtị okporo ígwè, isi ihe accumulator maka injectors, nweta nke a ukwuu pressurized fuel.The injectors weghara n'ebe ahụ. Unit Injectors The n'oge dizel injinia nwere ike mgbe niile na-ahụ nsogbu na-emepụta na edoghi ejikọta na-agbanye mgbapụta mmanụ ọkụ injector.So, na 1905, Carl Weidman ọkọdọ Bibie ha site combing na-agbanye mgbapụta na injector. The unit injector bụ kọmpat fuel injection imewe nke mgbapụta plunger emepụta elu nsogbu site a n'ibu ike n'ọrụ site engine. The plunger na injector ngwakọta n'ime otu unit nke ọrụ bụ ịnapụta ndị mmanụ ụgbọala ịgba na combustion ụlọ. Anyị nwere ike ịhụ na unit injector ide ọtụtụ ka Volkswagens na nnukwu dizel engines.
