ABSTRACT:
An exhaust system for a multi-cylinder internal combustion engine employs exhaust port liners each connected to a pair of adjacent exhaust ports and having a single discharge opening. An intake passage leads from each discharge opening to an auxiliary reaction chamber. Each intake passage may communicate with the same auiliary reaction chamber, or separate auxiliary reaction chambers may be provided for each intake passage. In either case, a main reaction chamber surrounds and encloses the auxiliary reaction chamber(s), and an outer chamber surrounds and encloses the main reaction chamber. Each auxiliary reaction chamber discharges into the main reaction chamber through an opening, and a misaligned opening connects the main reaction chamber to the outer chamber. If two auxiliary reaction chambers are employed, their openings are placed so that the streams of exhaust gases passing through them intersect within the main reaction chamber.
