ABSTRACT:
A temperature of an internal combustion engine is sensed when the engine is started and elapsed time from engine start is also sensed. Engine intake air temperature is estimated on the basis of the sensed engine temperature and sensed elapsed time. The operation of the engine is controlled in accordance with the estimated engine intake air temperature.
