摘要：
A control device for an internal combustion engine having an oxygen sensor, and calculation means for calculating a weight of oxygen fed to the internal combustion engine. The oxygen sensor outputs a signal corresponding only to a density of oxygen contained in intake gas fed to the engine. The oxygen sensor has a diffusion layer having pores through which oxygen molecules pass, the pores having a diameter less than or equal to the mean free path of the oxygen molecules contained in the intake gas.
