<P>PROBLEM TO BE SOLVED: To prevent the freezing of a throttle valve without addition of piping or the like in a fuel injection device of internal combustion engine having fuel injection valves arranged on the upstream side and downstream side of the throttle valve, respectively. <P>SOLUTION: This fuel injection device of internal combustion engine has the upstream fuel injection valve provided on the upstream side from the throttle valve and the downstream fuel injection valve provided on the downstream side from the throttle valve. This device has a means 101 for determining the total injection quantity of the fuel injection valves, a means 102 for determining the ratio of fuel injection quantity by each fuel injection valve, means 2 and 3 for acquiring temperature information representing the temperature of the throttle valve, and a means 103 for correcting the ratio based on the temperature information. The correction means 103 reduces the injection ratio of the upstream fuel injection valve when the temperature of the throttle valve is low. <P>COPYRIGHT: (C)2004,JPO |
