<P>PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine having a function of suppressing the deterioration of an exhaust gas even when intake states are different between two intake ports in each cylinder of the internal combustion engine. <P>SOLUTION: The deterioration of the exhaust gas is suppressed by calculating intake quantities and intake temperatures in respective intake ports 5, 6 based on output signals of intake quantity sensors 11, 12 and intake temperature sensors 13, 14 arranged in respective intake ports 5, 6 of the internal combustion engine and setting the ratio of the quantities jetted from fuel jetting valves 9, 10 of respective intake ports 5, 6 to the total fuel jetting quantity corresponding to the intake temperature of the intake port in a low temperature side or the ratio of the intake temperatures of both intake ports 5, 6 to form a good mixed gas with reduced unvaporized fuel in each intake port. <P>COPYRIGHT: (C)2013,JPO&INPIT |
