Abstract

Method for converting the oxidizable components contained in the exhaust gases from an internal combustion engine, which starts by means of cold start, which instantaneously converts said exhaust gases, and at least a stoichiometric amount of air, through a converter system comprising a fixed bed of catalyst having a volume such that it provides a gas hourly space velocity of at least approximately 50,000, the heat capacity of said converter system being less than approximately 0.23 kcal/ºC .
