Abstract
A device and method for controlling an internal combustion engine (2) includes a charger (7) for increasing pressure of air supplied to the engine. IN addition, a catalyzer (10) for refining exhaust of the engine is provided. In dependence on the temperature of the catalyzer (10), the charger (7) is activated and the time point of the combustion is shifted in the direction of “late”.
Claims7
Device for controlling an internal combustion engine (2), comprising a charger (7) for increasing pressure of air supplied to the engine (2), wherein a catalyzer (10) for refining exhaust of the engine (2) is provided, wherein a combustion time point of the engine (20), is controllable, wherein in dependence on a temperature of the catalyzer (10) for heating of the catalyzer (10) to an operating temperature, the charger (7) is activated, and wherein the combustion time point is shifted in a direction of “late”.
Method for controlling an internal combustion engine (2), comprising the following steps:
- providing a charger (7) for increasing a pressure of air supplied to the engine;
- providing a catalyzer (10) for refining exhaust of the engine, wherein a time point of a combustion of the engine is controllable;
- activating a charger (7) in dependence on a temperature of the catalyzer (10) for heating of the catalyzer (10) to an operating temperature;
- and
- shifting the time point of combustion in a direction of “late”.
