Document Type and Number:
Japanese Patent JP6098595
Kind Code:
B2
Abstract:
An exhaust gas recirculation control device for an engine is provided. The device includes an EGR passage connecting an exhaust passage of the engine with an intake passage of the engine, an EGR amount adjustor for adjusting an EGR amount that is a recirculation amount of exhaust gas of the engine through the EGR passage, an adjustor controller for controlling the EGR adjustor to adjust the EGR amount, and a gear position detector for detecting a gear position of a transmission of a vehicle on which the engine is mounted. When the gear position detected by the gear position detector during an idle operation of the engine is a non-travel position, the adjustor controller performs an EGR amount increase control in which the EGR amount adjustor is controlled to increase the EGR amount to be higher than when the gear position is a travel position.
