From the flow analysis of the silencer for 8 kW diesel generators, the following results were obtained. For silencer-1, it was confirmed that the holes formed at the inlet-side portion connect into the exhaust pipe in the chamber. The exhaust pipe installed inside silencer-1 was integrally connected through the holes in the chamber. As a result, it was confirmed that the pressure inside the chamber was kept stable. It was confirmed that the pressure loss generated inside an absorptive type silencer such as silencer-2 was small. The differential pressure of the inlet-outlet of silencer-1 and silencer-2 was confirmed to be 494 Pa at 15 m/s, 859 Pa at 20 m/s, 1326 Pa at 25 m/s, and 1911 Pa at 30 m/s.
