Fuel reforming system for an internal combustion engine

摘要

A system for converting a rich air-fuel mixture to a reformed gaseous mixture containing hydrogen and for feeding the reformed gaseous mixture to an internal combustion engine comprises a carburetor for producing the rich air-fuel mixture, a vortex combustion type burner for imperfectly burning the mixture to produce heat and partially oxidized gaseous mixture, and a reactor vessel provided therein with a catalyst bed of annular cross-section. The partially oxidized gaseous mixture flows radially inwardly through the catalyst bed into a central passage defined by the annular catalyst bed so that the partially oxidized gaseous mixture is completely converted into the reformed gaseous mixture during the passage through the catalyst bed.
