Abstract
The exhaust system of an internal combustion engine is periodically dosed to recharge an SCR catalyst with ammonia. If dosing is scheduled and exhaust gas temperature is too low to ensure recharging, a forced increase in exhaust gas temperature is effected for the period of dosing. A diagnostic to confirm correct operation of a catalytic converter may advantageously run at the same time.
