<P>PROBLEM TO BE SOLVED: To provide a control apparatus of an internal combustion engine that prevents a deposit from accumulating to a nozzle while securing a supply of evaporation fuel, in an in-cylinder fuel injection type internal combustion engine. <P>SOLUTION: The apparatus includes: a nozzle temperature estimator for estimating a tip temperature (hereinafter, referred to as a nozzle temperature) of the fuel injection device arranged in a combustion chamber; and a deposit-increase temperature setter for setting the nozzle temperature which makes the deposit adhering to a tip of the fuel injection device increase (hereinafter, referred to as a deposit-increase temperature) according to a fuel pressure. On the basis of the nozzle temperature estimated by a tip temperature estimator and the deposit-increase temperature set by the deposit-increase temperature setter, an upper limit value of a purge gas supply to be supplied to an intake pipe of the internal combustion engine by a purge controller is set. <P>COPYRIGHT: (C)2012,JPO&INPIT |
