2 Usoro nyocha

2.1.Nledo ule Emere nyocha a na bench ule na Institute of Combustion Engines and Transport of Poznan University of Technology.Oche ule a nwere (e gosiri atụmatụ ya na ọnụ ọgụgụ 1): • Ụlọ Mpịakọta Mpịakọta (CVC) maka ịmegharị ọnọdụ in-cylinder (nrụgide azụ) nke a na-ahụkarị maka injection n'ime engine combustion;A na-echekwa oke ikuku ikuku ruo 10 MPa;Ụlọ ahụ nwere ohere anya na ọkụ halogen 500 W abụọ iji mee ka ọkụ na-enwu.

• Onye na-eme usoro iji mepụta akara njikwa (5 V, TTL) maka usoro ịgba ọgwụ na akara ngosi na-enye ike diode;mkpebi nke ngwaọrụ a bụ ±1 ns.

 • Ụgbọ okporo ígwè nkịtị maka ọkọnọ mmanụ;ọ na-agụnye mgbapụta mmanụ ọkụ dị elu Bosch CP 4.1, usoro nchịkwa iji nweta nrụgide mmanụ ụgbọala na ụgbọ okporo ígwè ruo 200 MPa na ihe ọzọ na-achịkwa iji gbanwee akara ngosi site na sequencer n'ime ọkụ eletrik kwesịrị ekwesị maka ndị injectors ịmalite ma mechaa usoro ịgba ọgwụ.

• Mkpọchi dị ugbu a (Chauvin Arnoux E3N na nha nha nke 10 mV/A) na impedance high impedance oscilloscope probe M007 site na Pico Technology.A na-eji ha abụọ tụọ akara ọkụ eletrik tupu injector.

 • Usoro nnweta nke nwere isi ihe abụọ: nke mbụ bụ AVL IndiModul ka ịdekọ akara ọkụ eletrik (nke a na-eji clamps na nyocha) na akara njikwa site na usoro;mkpebi nke 500 kHz maka akara n'oge ule a họọrọ;Ihe nke ọzọ bụ igwefoto dị elu HSS5 site na LaVision nwere ọsọ ndekọ nke 250 kfps.

3.2.Nlele ihe na nha nha Maka ule ndị ahụ, a họọrọ injectors ụgbọ oloko abụọ nke ụdị dị iche iche.Nke mbụ bụ piezoelectric injector nke Bosch na nke ọzọ bụ nke electromagnetic ụdị, bụkwa site na Bosch (ihe ha na-egosi na tebụl 1).
