Abstract
In a combustion chamber, auxiliary combustion is effected by using carbon monoxide and/or hydrogen immediately after each charge of the main fuel has been burnt up therein. This method of combustion enables the nitrogen oxides resulting from the combustion of the main fuel to be reduced and brought to extinction by the auxiliary combustion, with the result that the nitrogen oxide content of the exhaust gas from the said combustion chamber is depressed.
