Humidity compensated charge density control for an internal combustion engine

   
   

Apparatus and methods for determining a desired charge density for an engine having an inlet air pathway. A first characteristic indicative of an engine speed of the engine is determined. A second characteristic indicative of a load on the engine is determined. A third characteristic indicative of a humidity of air in the inlet air pathway. A value indicative of a desired charge density of a combustion mixture for the engine is determined as a function of the first, second, and third characteristics.

Aparato y métodos para determinar una densidad deseada de la carga para un motor que tiene un camino del aire de la entrada. Una primera característica indicativa de una velocidad del motor del motor se determina. Una segunda característica indicativa de una carga en el motor se determina. Una tercera característica indicativa de una humedad del aire en el camino del aire de la entrada. Un valor indicativo de una densidad deseada de la carga de una mezcla de la combustión para el motor se determina en función del primer, en segundo lugar, y de las terceras características.
