Analysis of crank and cam shaft position sensor variability
Riečica, Samuel ; Repka, Martin (referee) ; Šebela, Kamil (advisor)
This bachelor thesis deals with the working characteristics of crankshaft and camshaft position sensors used in the power unit to ensure correct injection and ignition of the fuel mixture. Their variability was determined by experimental comparison of sensor characteristics. Search of the types and designs of sensors used was carried out in the first phase. Measuring device, which represented a simplified shaft model for sensing characteristics, was designed and constructed in the next step. The experiment was conducted on a statistical sample of 100 pieces of sensors using the Hall effect. The characteristics of the sensors were recorded and evaluated using an oscilloscope with appropriate digital software. Statistical processing of the measured data was performed at the end of the thesis. The results show that the variability of the crankshaft and camshaft position sensors can have an impact on engine performance characteristics and exhaust emissions produced.
