<p>An exhaust duel has a venturi into which exhaust gases from an internal combustion engine flow. and an inner chamber having an ?outer frusto-conical shaped wall. The wall increases in cross- section downstream and terminates at a nozzle from which the exhaust gases discharge. The inner chamber is perforated and is surrounded by an inner chamber into which exhaust gases may flow. The nozzle has a curved inner wall which increases in cross-section downstream such that the exhaust gases which discharge through the nozzle and which are adjacent to the inner wall tend to adhere to the latter wall by reason of the Coanda effect. A number of such exhaust ducts are incorporated into an exhaust assembly which also includes a catalytic converter and a resonator.</p> |
