Japanese Patent JP2021156258
Kind Code:
A
Abstract:
To provide a model construction apparatus or the like capable of easily constructing a model in which a fuel behavior can be identified precisely.SOLUTION: A model construction apparatus 50 includes: one or more control parameter identification means for identifying one or more engine control parameters; one or more feature value identification means for identifying one or more feature value associated with adhesive properties of fuel to at least one of an air inlet port and an inner face of a combustion chamber; a feature value calculation unit 25 for calculating the one or more feature value on the basis of information from the one or more feature value identification means; and a learning unit 26 for performing construction by learning relevance between, one or more feature value calculated by the feature value calculation unit 25 about a model for calculating one or more feature value in an existing cycle by using the one or more feature value in the cycle before one from the existing cycle and the one or more engine control parameters in the existing cycle as the input parameter, and one or more engine control parameters identified by the one or more control parameter identification means.SELECTED DRAWING: Figure 1
