Abstract
A fuel injection control for an internal combustion engine includes: estimating a convergence temperature of the exhaust gas catalytic converter; calculating an OTP boost value using the estimated convergence temperature; and estimating the convergence temperature on the assumption that the temperature decrement quantity of the exhaust gas catalytic converter which is caused by the power boosting is zero when both of the OTP boosting execution condition and the power boosting execution condition are met.
