<P>PROBLEM TO BE SOLVED: To provide a fuel injection control apparatus which suppresses temperature rise in the apparatus caused by the driving of fuel injection valves, without requiring installation of a new cooling mechanism. <P>SOLUTION: The fuel injection control apparatus detects a temperature in the apparatus by an output signal of a thermistor provided in the apparatus, and when the detected temperature is T11 or below, permits execution of any of controls A to D of injection control. When the detected temperature exceeds T11 but is not more than T12, the apparatus permits execution of either of controls B and D under which a heat generation rate is large, and inhibits execution of the other one, and when the detected temperature exceeds T12, the apparatus inhibits execution of both of controls B and D. Furthermore, the fuel injection control apparatus permits execution of any of controls A to D when the engine speed is N11 or below, permits execution of either of controls B and D under which a heat generation rate is large and inhibits execution of the other one when the engine speed exceeds N11 but is not more than N12, and inhibits execution of both of controls B and D when the engine speed exceeds N12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
