摘要： A soot generation amount estimation apparatus obtains a generation speed of a precursor of soot (accordingly, the concentration of the precursor) in consideration of formation of the precursor from fuel, thermal decomposition of the formed precursor, and formation of soot from the formed precursor, and estimates a generation speed of soot (accordingly, the concentration of soot (the generation amount of soot)) in consideration of formation of soot from the precursor, which depends on the concentration of the precursor, and oxidation of the formed soot. The apparatus employs a reaction model in which the reaction process in which soot is generated from fuel is divided into two steps; i.e., a reaction process in which a precursor is generated from fuel and a reaction process in which soot is generated from the precursor. Thus, phenomena, such as a “delay in soot generation” in the reaction process in which soot is generated from fuel, can be accurately simulated.
