| Abstract: | Data acquisition and analysis system for in-cylinder pressure signals of CNG engines is developed by using virtual instrument technology. Substituting most of hardware by software, the PC based system can achieve functions of continuous acquisition of in-cylinder pressure signals, data record and combustion analysis. Methods for data acquisition, data storage and digital filtering and implementation of their corresponding software are focused. |
