  • Method for determining the cylinder air-charge of an internal combustion engine in a non-fired operation
    Patent number: 11022054
    Abstract: A method for determining the cylinder air-charge of an internal combustion engine in a non-fired operation, wherein a method for determining the cylinder air-charge in a fired operation is performed. According to the invention, provision is made that in the method for determining the cylinder air-charge in the fired operation, a correction factor is provided as a function of engine speed and engine load which adjusts the value of the cylinder air-charge determined by the method in the fired operation to the non-fired operation. Thus, the previously known methods can be improved and made more efficient, in particular in view of the deviations of up to 30% between the cylinder air-charge values in the non-fired operation and the modeled values of the fired operation.
