| Abstract: | By means of experiments,a through study of the frequency spectrum of the vibration signals induced by the cylinder pressure at the cylinder cap of a gasoline engine is made according to the valve distributing mechanism phase,the transfer properties of the cap and the characteristics of the frequency spectrum of combustion pressure in the cylinder. The work reported here reveals the mechanism of that the signals possess such frequency spectrum characteristics. |
