Abstract (en)
[origin: WO2019219384A1] The invention relates to a method for calculating a fresh air mass in a cylinder (2) of an internal combustion engine (1), comprising: determining (36) a heating of the fresh air (7) on a wall (2a) of the cylinder (2), the temperature of the wall (2a) of the cylinder changing dynamically; and calculating (41) the fresh air mass of the fresh air (7) in the cylinder (2) on the basis of the determined heating of the fresh air mass.
