EXHAUST REACTION CHAMBER ASSEMBLY FOR INTERNAL COMBUSTION ENGINE

摘要

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.
