Zusammenfassung:	To provide a modification fuel control method and modification fuel controller which equalize the distribution of fuel for modification injected into recirculating exhaust gas passing through a fuel modification catalyst.SOLUTION: A flow rate of recirculating exhaust gas is detected. According to the flow rate of the recirculating exhaust gas, a region of a fuel modification catalyst 16 through which the recirculating exhaust gas and fuel for modification pass is changed. When the flow rate of the recirculating exhaust gas is smaller than a predetermined value, the change of the region is set small. When the flow rate of the recirculating exhaust gas is larger than the predetermined value, the change of the region is set to all of the region.SELECTED DRAWING: Figure 1 【課題】燃料改質触媒を通過する再循環する排気ガスに噴射する改質用燃料の分布を均一化する改質燃料制御方法および改質燃料制御装置を提供する。【解決手段】再循環する排気ガスの流量を検出し、再循環する排気ガスの流量に対応して、再循環する排気ガスと改質用燃料が通過する燃料改質触媒１６の領域を変化させ、領域の変化は、再循環する排気ガスの流量が所定値よりも少ない場合には小さくし、所定値よりも多い場合には全領域とする。【選択図】図１
