Abstract
A diverter ( ) is provided, which is of low cost and which is effective in more evenly distributing exhaust gasses passing from a small diameter upstream exhaust gas pipe section ( ) into a much larger diameter catalytic converter assembly ( ). The diverter includes a diverter element ( ) and mounting brackets ( ). The diverter element has a central hole ( ) and has conical walls with an included angle of at least 70°, the conical walls having a plurality of holes ( ). The large conical angle (G) of the diverter effectively directs exhaust gases to the periphery of the large diameter catalytic converter but blocks a radially intermediate portion of the catalyst, while the holes in the conical diverter walls allow sufficient exhaust gases to reach the radially intermediate portion of the catalyst.
