ABSTRACT:
An intake-air quantity estimation apparatus for an internal combustion engine, including an intake-air quantity estimation device that includes a cylinder pressure estimation device that estimates pressure within a cylinder through calculation using a model of the cylinder obtained based on a law of conservation of energy, the intake-air quantity estimation device estimates a cylinder intake-air quantity based on the estimated pressure within the cylinder, the cylinder intake-air quantity representing the amount of air flowing into the cylinder.
