<p>A control system (14) is described for an internal combustion engine having a catalytic converter and a heater (12) for raising the temperature of the catalyst in the catalytic converter. The control system comprising an electrical circuit (16) for estimating, rather than measuring, the temperature of the catalyst and means for controlling the heater (12) of the catalytic converter based on the estimated catalyst temperature.</p> |
