Abstract

See full text

A muffler for a combustion engine includes walls forming a chamber, a first inlet, a first outlet, and a conduit. The first inlet is designed to receive exhaust gases from an exhaust duct of the engine. The exhaust gases pass through the chamber when moving from the first inlet to the first outlet. The exhaust gases then exit the muffler through the first outlet. The conduit extends between a second inlet and a second outlet. The second inlet is configured to receive fresh air entering the muffler. The fresh air then exits the conduit and is introduced into the exhaust gases through the second outlet.
