燃焼演算装置
Document Type and Number:
Japanese Patent JP6688186
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten control delay in controlling an internal combustion engine, in a combustion calculation device for calculating combustion on the basis of an in-cylinder pressure value.SOLUTION: A combustion calculation device for calculating a calculation value used for controlling a combustion calculation device calculates a calculation value used for controlling the next cycle during an exhaust stroke of present cycle on the basis of an in-cylinder pressure value acquired from an intake stroke of the present cycle of an internal combustion engine, a compression stroke of the present cycle, a combustion stroke of the present cycle and an in-cylinder pressure estimation value of an exhaust stroke.SELECTED DRAWING: Figure 2
