Vibration measurements are now widely applied and developed field of science. The article is an example of the application of that field diagnostic using the accelerometer. The study was conducted at Honda GX630 combustion engine in a current generator system. The generator is characterized in that it can be powered by either liquid fuel, or which gas. The results of vibration measurements is presented for (both) gas mixtures containing varying concentrations, as well as for gasoline. The paper presents the results of the vibration, based on an analysis of the time and frequency domain, using Fast Fourier Transform. In the analysis analogue filters, and digital filters (windowing) was used. The analysis includes proposals concerning vibrations difference for individual substances in comparison to vibrations of engine powered a classic, liquid fuel. To simplify the analysis, and thus the discussion on the results, the data presented in the charts with honours major changes in the received, digitized results. Measurements and results presented in the article were carried out as part of a pilot project to support research and development in scale demonstration DEMONSTRATOR+ (WND- DEM-1-527 / 001).
