摘要:
A method and an apparatus for determining the temperature of a gas charge in a cylinder of an internal combustion engine increase the accuracy with which the temperature of the gas charge is determined. The gas charge includes a residual gas portion and a fresh gas portion. The temperature of the gas charge is determined by ascertaining the temperature of the fresh gas portion, the proportion of the fresh gas portion in the gas charge, the temperature of the residual gas portion, and the proportion of the residual gas portion in the gas charge. The temperature of the gas charge is calculated based on these ascertained quantities.
