Tuned exhaust manifold

Patent ·
OSTI ID:6049855
An exhaust manifold is described for attachment to an engine having exhaust ports, the exhaust manifold comprising a housing formed to include an exhaust chamber, inlet means for admitting combustion product discharged from the engine exhaust ports into the exhaust chamber, and outlet means for exhaust combustion product from the exhaust chamber, the housing including an inner shell providing the inlet means and an outer shell attached to the inner shell at a perimetrically extending split line, the inner and outer shell cooperating to define the exhaust chamber therebetween, and baffle means rigidly fixed in the exhaust chamber for partitioning the exhaust chamber to define separate passageways connecting each of the engine exhaust ports to the outlet means so that the flow of combustion product discharged from each engine exhaust port and admitted into the exhaust chamber is substantially isolated in its companion passageway as it is conducted through the housing to permit performance tuning of the exhaust manifold, the baffle means including at lest one baffle rigidly attached to the housing at the split line.
