2 ʻAno noiʻi

2.1. Kū hoʻāʻo Ua mālama ʻia ka noiʻi ma ka papa hoʻāʻo ma ka Institute of Combustion Engines and Transport of Poznan University of Technology. Aia kēia papa ho'āʻo (hōʻike ʻia kona ʻano ma ke kiʻi 1): • He Keʻena Volume Mau (CVC) no ka hoʻohālikelike ʻana i nā kūlana in-cylinder (paʻi hope) maʻamau no ka hoʻoheheʻe ʻana i loko o ka ʻenekini puhi ahi; Ua mālama ʻia ke ʻano o ke ea a hiki i 10 MPa; Loaʻa i ke keʻena ke komo ʻike a me ʻelua mau kukui halogen 500 W e hoʻomālamalama i nā hāʻule wahie.

• He mea hoʻoponopono e hoʻopuka i nā hōʻailona mana (5 V, TTL) no ka ʻōnaehana injection a me nā hōʻailona e mana ana i ka diode; ʻO ka hoʻonā ʻana o kēia hāmeʻa he ±1 ns.

 • He kahua kaaahi no ka hoolako wahie; aia i loko o ke kaomi wahie kiʻekiʻe ʻo Bosch CP 4.1, kahi ʻōnaehana hoʻokele e hoʻokō ai i ke kaomi wahie ma ke kaʻaahi a hiki i 200 MPa a me kahi ʻāpana hoʻokele ʻē aʻe e hoʻololi i nā hōʻailona mai ka sequencer i hōʻailona uila kūpono no nā injectors e hoʻomaka a hoʻopau i ke kaʻina hana injection.

• ʻO nā mea hoʻopili o kēia manawa (Chauvin Arnoux E3N me ke ana ʻana o 10 mV/A) a me ka passive high impedance oscilloscope probe M007 e Pico Technology. Ua hoʻohana ʻia nā mea ʻelua e ana i nā hōʻailona uila ma mua o ka injector.

 • ʻO kahi ʻōnaehana kūʻai i loaʻa i ʻelua mau mea nui: ʻo ka mea mua ʻo AVL IndiModul e hoʻopaʻa i nā hōʻailona uila (ana ʻia e nā pipili a me ka probe) a me nā hōʻailona hoʻomalu mai ka sequencer; ua koho ʻia ka hoʻonā o 500 kHz no nā hōʻailona i kēia hoʻāʻo; ʻO ka mea ʻē aʻe ka pahu kiʻekiʻe HSS5 e LaVision me ka wikiwiki hoʻopaʻa ʻana o 250 kfps.

3.2. Nā mea hoʻāʻo a me ke ana ʻana No nā hoʻāʻo ʻana ua koho ʻia nā injectors maʻamau ʻelua o nā ʻano like ʻole. ʻO ka mea mua he piezoelectric injector e Bosch a ʻo ka mea ʻē aʻe he ʻano electromagnetic, a na Bosch pū kekahi (hōʻike ʻia ko lākou mau palena ma ka papa 1).
