Abstract
On incompletion of port learning, an auto stop-permitting water temperature is set to a temperature which is higher than a temperature set on completion of the port learning and is higher than a port injection temperature as an upper limit temperature that enables an engine to be driven in a port injection drive mode. This arrangement increases the opportunity of continuing the operation of the engine with fuel injection from a port fuel injection valve without an auto stop, thus increasing the opportunity of the port learning.
