Title:
内燃機関のＥＧＲ制御装置
Document Type and Number:
Japanese Patent JP5660323
Kind Code:
B2
Abstract:
A gas temperature sensor is provided in an EGR passage. When a specified learning executing condition is established, the EGR valve is compulsorily rotated from a reference position in a valve-close direction and then rotated in a valve-open direction over the reference position. While the EGR valve is rotated in such a manner as to pass a full-close position, an opening degree of the EGR valve at which the variation in gas temperature becomes minimum is learned as the full-close position of the EGR valve.
