Title:
内燃機関の制御方法及び内燃機関の制御装置
Document Type and Number:
Japanese Patent JP6892324
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To relatively increase an opportunity to obtain a fuel efficiency improvement effect through EGR.SOLUTION: An internal combustion engine control device comprises: an intercooler 13 which cools intake air; an EGR passage 21 which returns a portion of exhaust to an intake air passage 2 as EGR gas at an upstream side of the intercooler 13; an EGR valve 22 which adjusts a flow rate of the EGR gas flowing in the EGR passage 21; and an external air introduction mechanism 41 which adjusts an introduction amount of external air into an engine room. The internal combustion engine control device adjusts the flow rate of the EGR gas in accordance with presence or absence of the external air introduced into the engine room through the external air introduction mechanism 41 when a temperature of intake air at an intake air introduction port of the intake passage 2 is less than a predetermined temperature. Thus, the internal combustion engine control device can increase an opportunity to obtain a fuel efficiency improvement effect through execution of EGR even in a cold region.SELECTED DRAWING: Figure 9
