Kusanthula kwa Transient states kwa majekeseni a injini ya CI pogwiritsa ntchito njira zowunikira(GAWO 4)

2 Njira zofufuzira

2.1. Mayeso oyeserera Kafukufukuyu adachitika pa benchi yoyeserera mu Institute of Combustion Engines and Transport ya Poznan University of Technology. Benchi yoyezerayi imakhala ndi (chiwembu chake chikuwonetsedwa mu chithunzi 1): • A Constant Volume Chamber (CVC) yofanizira mikhalidwe ya in-cylinder (kumbuyo-kupanikizika) komwe kumapangidwira mu injini yoyaka moto; kuthamanga kwa mpweya kumasungidwa mpaka 10 MPa; chipinda ali ndi mwayi kuwala ndi awiri 500 W halogen nyali kuunikira madontho mafuta.

• Sequencer kuti apange zizindikiro zowongolera (5 V, TTL) za jekeseni wa jekeseni ndi zizindikiro zomwe zimagwiritsa ntchito diode; Kusintha kwa chipangizochi ndi ± 1 ns.

 • Sitima yapamtunda wamba yopangira mafuta; imakhala ndi pampu yothamanga kwambiri yamafuta a Bosch CP 4.1, makina owongolera kuti akwaniritse kuthamanga kwamafuta mu njanji mpaka 200 MPa ndi gawo lina lowongolera kuti asinthe ma sign kuchokera pa sequencer kukhala chizindikiro chamagetsi choyenera kuti majekeseni ayambe ndikumaliza jekeseni.

• Makapu apano (Chauvin Arnoux E3N yokhala ndi mphamvu yoyezera 10 mV/A) komanso kafukufuku wopangidwa ndi Pico Technology wa Pico. Zonsezi zinagwiritsidwa ntchito kuyesa zizindikiro zamagetsi pamaso pa jekeseni.

 • Dongosolo lopeza lomwe lili ndi zinthu ziwiri zazikulu: yoyamba ndi AVL IndiModul yolemba zizindikiro zamagetsi (zoyesedwa ndi ma clamps ndi probe) ndikuwongolera zizindikiro kuchokera ku sequencer; kusamvana kwa 500 kHz kwa ma siginecha panthawi ya mayesowa kunasankhidwa; china chake ndi kamera yothamanga kwambiri ya HSS5 yolembedwa ndi LaVision yokhala ndi liwiro la 250 kfps.

3.2. Zinthu zoyesa ndi miyeso yoyezera Pa mayesowo ma jakisoni a njanji wamba amitundu yosiyanasiyana adasankhidwa. Yoyamba inali jekeseni ya piezoelectric yopangidwa ndi Bosch ndipo inayo inali yamtundu wa electromagnetic, komanso ndi Bosch (magawo awo akuwonetsedwa patebulo 1).
