A burner system for cleaning exhaust gases in the exhaust line of an internal combustion engine during start-up of the engine. The burner system serves to heat the catalytic convertor during start-up. The burner system has a burner including a combustion chamber for supplying combustion gases to the catalytic converter. A fuel line connected to the fuel injection system of the engine supplies fuel to the burner and a fuel regulator is provided in the fuel line. A secondary sir supply system supplies secondary air to the burner and includes an air fan, an air line connecting the air fan to the burner and a pressure regulator in the air line. The pressure regulator is subjected to the pressure prevailing in the combustion chamber or in the exhaust line for the exhaust gases of the internal combustion engine.
