<p>More comfortable traveling state is ensured by suppressing deterioration in deceleration feeling at low temperature and enhancing drivability. When a decision is made that the water temperature of engine cooling water or the fuel temperature has dropped below a predetermined temperature possibly causing deterioration in deceleration feeling or reached a predetermined temperature region, slow-down amount is incremented and a large-scale slow-down injection is performed such that time required for injection is prolonged and the quantity of fuel injected in unit time is decreased as compared with slow-down injection performed at a normal temperature. Drivability is enhanced by suppressing deterioration in deceleration feeling and preventing difference from occurring between it and deceleration feeling of slow-down injection at a normal temperature.</p>
