Title:
エンジン制御装置
Document Type and Number:
Japanese Patent JP5803766
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an engine control device in which a rotating speed of a compressor can be estimated accurately according to a simple method regardless of the presence/absence and introduction quantity of an EGR gas.SOLUTION: An engine control device includes an acquisition means, a storage means and an estimation means. At a downstream side from a connecting part of an intake pipe 11 and EGR piping 13 and a compressor 16a, the acquisition means acquires an intake density correlation value correlated with an intake density within the intake pipe 11. The storage means stores a correlation between an intake density correlation value prepared beforehand and a rotating speed of the compressor 16a. The estimation means estimates the rotating speed of the compressor 16a on the basis of the intake density correlation value acquired by the acquisition means and the correlation stored in the storage means.
