22. Method of treating exhaust gases of an internal
combustion engine comprising the steps of passing a first
portion of said exhaust gases through an igniter containing a
catalyst material, passing a second portion of the exhaust
gases through a bypass passage bypassing said igniter, said
second portion being greater than said first portion,
permitting said catalyst within said igniter to increase the
temperature of the exhaust gases passing through the igniter,
passing the exhaust gases through a catalyst bed within a
catalytic converter after said first portion of the exhaust
gases has passed through the igniter and the temperature of
the exhaust gas has been raised to a temperature to ignite the
