One of the essential parts of Compressed Natural Gas (CNG) powered engines is the pressure regulator which reduces the storage pressure (up to 250 bar) from the tank system to a near constant outlet pressure of approximately 2 up to 10 bars within the fuel injection system .

To generate fundamental data for the scientific project described in this paper a standard mechanical pressure regulator for CNG-powered engines was investigated theoretically and practically. Thereto the particular components of such a system were modeled, simulated and verified by comparison of measured and simulated results. In the next step the modeled state of the art mechanical pressure regulator was substituted by new developed mechatronical devices and the space of improvement for different versions of those pointed out based on simulation. Subsequently the realized mechatronical pressure regulators with the major potential for further development were practically investigated on a test rig at Trier University of Applied Sciences. Experiments and Simulations are aligned here to validate a new device. The main advantages that accrue by using a mechatronical pressure regulator instead of an ordinary mechanical one are demonstrated.» weiterlesen» einklappen
