Abstract
The exhaust pipe has apertures in its side walls for escape of the exhaust gas, and is encased by at least one surrounding chamber. This also has apertures for the gas, but not aligned with those in the pipe. The apertures in the chamber are baffled by a plate attached to the chamber outer wall and parallel or coaxial to the latter, to provide a divergent gas stream escaping into the atmosphere.
