<p><P>PROBLEM TO BE SOLVED: To restrain an excessive rise in the DPF temperature and a sudden change in an operation state, when starting regeneration processing of a PM collecting filter (DPF). <P>SOLUTION: When starting the regeneration processing, when changing a control quantity (for example, a fuel injection timing delay quantity) RT for raising the DPF temperature, switching time ts for changing this quantity up to a set value RTm on a map from a present value (an initial value O), is set in response to a deviation between the target DPF temperature and the actual DPF temperature, and a PM deposit quantity of DPF. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
