2 Hanyar bincike

2.1. Tsayuwar gwaji An gudanar da binciken ne a kan bencin gwajin da ke Cibiyar Konewa Injiniya da Sufuri na Jami'ar Fasaha ta Poznan. Wannan benci na gwaji ya ƙunshi (ana nuna makircinsa a adadi na 1): • Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwaƙwalwa na Ƙaƙwalwa na Ƙaƙwalwa na Ƙaƙwalwa na Ƙaƙwalwa na Ƙaƙwalwa na Ƙaƙwalwa na Ƙaƙƙarfan Ƙaƙƙarfan Ƙaƙƙarfan Ƙaƙƙarfan Ƙaƙƙarfan Ƙaƙƙarfan Ƙaƙƙarfan Ƙaƙwal ) na Ƙaƙwalwa na Ƙaƙwalwa (CVC) da aka yi don daidaita yanayin in-Silinda (matsi na baya) na yau da kullum don allura a cikin injin konewa; An kiyaye iyakar iska har zuwa 10 MPa; ɗakin yana da damar gani da kuma fitilun halogen 500 W guda biyu don haskaka faɗuwar mai.

• Mabiyi don samar da siginar sarrafawa (5 V, TTL) don tsarin allura da siginar da ke kunna diode; ƙudurin wannan na'urar shine ±1 ns.

 • Tsayin dogo na gama gari don samar da mai; ya ƙunshi babban famfo mai matsa lamba Bosch CP 4.1, tsarin sarrafawa don cimma matsa lamba a cikin dogo har zuwa 200 MPa da wani sashin kulawa don canza sigina daga mabiyi zuwa siginar lantarki mai dacewa don masu injectors don farawa da gama aikin allurar.

• Matsala na yanzu (Chauvin Arnoux E3N tare da ma'aunin ma'auni na 10 mV/A) da m high impedance oscilloscope bincike M007 ta Pico Technology. Dukansu an yi amfani da su don auna siginar lantarki kafin injector.

 • Tsarin saye wanda ya ƙunshi manyan abubuwa guda biyu: na farko shine AVL IndiModul don yin rikodin siginar lantarki (wanda aka auna ta hanyar clamps da bincike) da kuma siginar sarrafawa daga mabiyi; an zaɓi ƙuduri na 500 kHz don sigina yayin wannan gwajin; ɗayan abubuwan shine kyamarar HSS5 mai sauri ta LaVision tare da saurin rikodi na 250 kfps.

3.2. Gwajin abubuwa da kewayon auna Don gwaje-gwajen an zaɓi alluran layin dogo na gama gari na iri daban-daban. Na farko shine injector piezoelectric ta Bosch kuma ɗayan na nau'in electromagnetic ne, shima ta Bosch (ana nuna sigoginsu a tebur 1).
