<P>PROBLEM TO BE SOLVED: To use DPF jointly, in realizing a pilot-main injection mode with low heat rate. <P>SOLUTION: In this compression ignition type internal combustion engine that controls the amount and the timing of fuel injected from a fuel injection valve 9 and that has a DPF scavenging particulate in exhaust gas, to an exhaust passage 13, and burning it, at least a pilot injection has a pilot-main injection mode with low heat rate that is executed at the amount and the timing in which the maximum heat release rate by the injected fuel, is 60 kJ/s or less, and when the fuel injection is controlled so that the operating condition is made to raise the temperature of the exhaust gas to burn particulate collected by the DPF when the temperature of the exhaust gas is low, the pilot-main injection mode with low heat rate is prohibited. <P>COPYRIGHT: (C)2003,JPO |
