Title:
圧縮自己着火式エンジンの制御装置
Document Type and Number:
Japanese Patent JP6555538
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a control device for a compression self-ignition type engine which performs SI-CI combustion, for appropriately controlling both a SI rate and a self-ignition timing.SOLUTION: A compression self-ignition type engine 1 performs SI combustion, namely, the combustion of air-fuel mixture with its flame propagation by the ignition of a spark plug 25 and CI combustion, namely, the combustion of the air-fuel mixture with its self-ignition resulting from the flame propagation. An ECU 10 includes first control means for controlling an SI rate as a parameter related to the rate of a heat quantity generated in the SI combustion to a total heat quantity generated in the SI combustion and the CI combustion or a heat quantity generated in the CI combustion on the basis of the operating condition of the engine 1, and second control means for controlling an in-cylinder temperature before the SI combustion. Both the first and second control means are used for changing the combustion states of both the SI combustion and the CI combustion during one combustion cycle of the engine 1 according to the operating condition of the engine 1.SELECTED DRAWING: Figure 8
