Silencer for internal combustion engine, with specified ratios for outlet tube clearance

摘要

The silencer has a ratio of the clearance (a) measured from the gas outlet end (p) of an outlet tube (42) to the inside (46) of the rear partition wall (40), to the internal diameter (A) of the outlet tube within limits 0.6-1.2. The ratio of the clearance (B) measured from the other gas inlet end (q) of the exhaust tube (44) to the inside of the front partition wall (38) to the internal diameter (B) of the exhaust tube within limits 0.4-1.2.
