Abstract

In an NOx generation quantity estimation method for an internal combustion engine, the concentration of a gas contained in intake gas and serving as a material for generation of NOx, (intake-gas oxygen concentration), a load index value indicating the load of the engine (fuel injection quantity), an atomization index value indicating the degree of atomization of fuel within the combustion chamber (fuel injection pressure), and the highest flame temperature are selected as peripheral condition quantities in relation to gas mixture which affect the quantity of NOx generated in a combustion region as a result of combustion. A combustion-generated NOx quantity per unit fuel quantity (combustion-generated NOx ratio) is obtained on the basis of the four peripheral condition quantities and a predetermined empirical formula which defines the relation between the four peripheral condition quantities and the combustion-generated NOx ratio. Subsequently, the quantity of generated NOx is estimated through multiplication of the combustion-generated NOx ratio by the fuel injection quantity.
