<p>A method of operating a catalytic converter which incorporates a heater, to treat exhaust gas from an engine, comprising at the time of starting the engine, energising the heater at a power level of at least 1.5kW per unit m<3>/min flow rate of exhaust gas, while supplying an oxidising gas to the catalytic converter, and when the temperature of the heater has exceeded a value at which a main catalyst carried on the heater, functions, reducing the power level of the heater and suspending supply of the oxidising gas.</p> |
