Abstract.

E mepụtara ụdị mgbakọ na mwepụ nke injector mmanụ ụgbọala nkịtị nke solenoid. Ọdịiche ya na ụdị dị adị bụ simulation valvụ njikwa. A na-eji injector ụgbọ okporo ígwè nkịtị nke 0445110376 Series (Cummins ISf 2.8 Diesel engine) nke ụlọ ọrụ Bosch mepụtara dị ka ihe nyocha. Ekpebiri paramita injector (nnyefe mmanụ na azụ azụ) site na mgbako na ụzọ nnwale. GT-Suite nlereanya nkezi R2 bụ 0.93 nke pụtara na ọ na-ebu amụma n'ụdị ịgba ọgwụ n'ụzọ ziri ezi (nominal na oke ọrụ nka nke injector). Nyocha ọnụọgụgụ na nyocha nyocha gosiri na njikwa valvụ na-achịkwa na-abawanye nkwụsị azụ na nnyefe mmanụ (karịsịa na 160 MPa). E mepụtara ụdị nlọghachi azụ maka ịchọpụta nnyefe mmanụ na mmetụta azụ azụ na nrụgide mmanụ ọkụ na oge na-enye ume (maka ọnọdụ teknuzu n'ọnụ na nke oke).

Ọtụtụ n'ime ụgbọ ala ọgbara ọhụrụ nwere injin dizel nwere sistemụ ịgbanye mmanụ ụgbọ okporo ígwè. Ha na-enyere aka imezu ihe ndị siri ike maka ọnụego ikuku ikuku. Nke a ga-ekwe omume n'ihi nnukwu nrụgide mmanụ ụgbọala (ruo mgbe 300 MPa) na iji mmanụ mmanụ biodiesel [1-4]. Ndị injectors ụgbọ okporo ígwè ndị a na-ahụkarị bụ akụkụ kachasị mkpa nke sistemu [5]. Ha na-ekwe ka nnyefe mmanụ n'ime cylinders nwere oke ziri ezi dabere na ọnọdụ engine arụ ọrụ. Enwere ụdị injectors abụọ - nwere piezo actuators yana ndị na-arụ ọrụ solenoid [6-8]. Nke ọ bụla n'ime ha nwere ụfọdụ uru na ọghọm ya [9]. N'agbanyeghị ụdị injector ejiri mee ihe, a ga-enwerịrị izi ezi nke nnyefe mmanụ ruo ogologo oge. Ọnọdụ nka na ụzụ nke sistemu ịgbanye mmanụ ụgbọ oloko na-agbanwe site na mmụba ihe nketa ụgbọ ala [10].
