Abstract
An exhaust flow treatment apparatus to treat exhaust flow emitted by a combustion engine is configured to receive unburnt fuel for combustion therein after confirming that conditions are such that the unburnt fuel is likely to combust in the apparatus. A method of controlling operation of an exhaust flow treatment apparatus includes confirming that the temperature of fluid in the apparatus exceeds a threshold temperature before allowing unburnt fuel into the apparatus. The method may confirm a particular mode of operation of the exhaust flow treatment apparatus to determine the appropriate quantity of fuel for burning in the apparatus.
