ABSTRACT:
An exhaust reaction chamber assembly for use with an internal combustion engine having cylinders in line includes one or more chambers divided by a metal partition to form separate compartments sealed from each other. A downstream chamber which is not divided surrounds and encloses the divided chamber or chambers and also surrounds and encloses a major portion of the length of each of a plurality of exhaust branches which are connected to individual exhaust ports, respectively. In this way the temperature of the exhaust gases is maintained at a high level in order to promote rapid oxidation of HC and CO in the exhaust gases. Two exhaust reaction chamber assemblies are disclosed, one for a six cylinder engine and one for a four cylinder engine.
