Abstract
In this paper, we tested the GW 2.4S automobile engine and Mltsublshi2.4S automobile engine by adopting sound intensity method. During the experiment we got the spectrum graph, and by matching the spectrum peak from the spectrum graph and spectrum peak from the total engine noise to conclude the main noise source. By comparing Peak of the low frequency and the high frequency at the different measuring surface of the engine, we can speculate the engine's noise source, and then we can get different types of engine's noise source at the different frequency. After that, these two engines' noise source is estimated by using the sound power from the each side of these two engines. Mechanical noise and combustion noise also can be separated preliminary.
