Abstract
A valve disposed in the central space of the manifold normally divides the space into two halves to avoid mutual interference of exhaust gas flows. At low engine speeds, the valve causes the exhaust gas flows from all branches to be disturbed and to mix with each other, to promote oxidation of HC and CO.
