ンの排気還流制御装置。[Scope of Claim for Utility Model Registration] Exhaust of a diesel engine equipped with an EGR control device that receives an output from an accelerator opening detection means and changes the amount of EGR around a predetermined set value of the accelerator opening. The reflux control device includes: a fuel temperature detection means for detecting the temperature of the fuel; and an output from the fuel temperature detection means, when the fuel temperature is low compared to when the fuel temperature is high.
An exhaust gas recirculation control device for a diesel engine, comprising: a correction means for correcting the set value of the accelerator opening degree in a direction of decreasing it.
