IPC: F02D41/34
Filed: 2016-02-15
Abstract: PROBLEM TO BE SOLVED: To suppress the combustion noise of an internal combustion engine which performs compression self-ignition combustion.SOLUTION: In a control device 200 of an internal combustion engine 100 in which there appears a temperature region in which a change of an ignition delay time accompanied by a rise of an in-cylinder temperature during a chemical reaction of fuel is suppressed when a pre-mixed gas is compression self-ignition combusted in a cylinder 10, the control device comprises a fuel injection control part which sequentially injects primary fuel and secondary fuel from a fuel injection valve 20 so that the pre-mixed gas is compression self-ignition combusted in the cylinder 10. When the self-ignition timing of the secondary fuel becomes earlier than the self-ignition timing of the primary fuel which is injected at a prescribed crank angle due to the injection of the secondary fuel at a crank angle at which an in-cylinder temperature reaches a high-temperature side rather than the temperature region, the fuel injection control part lowers a ratio of the secondary fuel which occupies a total fuel injection amount more than the case that the self-ignition timing of the secondary fuel is retarded more than the self-ignition timing of the primary fuel which is injected at the prescribed crank angle due to the injection of the secondary fuel at a crank angle at which the in-cylinder temperature falls within the temperature region.SELECTED DRAWING: Figure 1
