ENGINE DEVICE

To inhibit a second-time fuel injection amount from exceeding the maximum fuel injection amount in the partial injection when performing fuel injections including a first-time full injection and second- and third-times partial injections.SOLUTION: When performing three times of injections in which fuel injection is performed three times, a first-time fuel injection is performed as full injection and second- and third-times fuel injections are performed as partial injections. At that time, a total fuel injection amount and a third-time fuel injection amount are set, and a first-time fuel injection amount and a second-time fuel injection amount are set by multiplying a value obtained by subtracting the third-time fuel injection amount from the total fuel injection amount by a division rate. In this case, the first-time fuel injection amount and the second-time fuel injection amount are set so that the second-time fuel injection amount is equal to or smaller than the maximum fuel injection amount in the partial injection.SELECTED DRAWING: Figure 2 【課題】１回目を全開噴射、２回目と３回目を部分噴射により燃料噴射する際に、２回目の燃料噴射量が部分噴射における最大燃料噴射量を上回るのを抑止する。【解決手段】３回に亘って燃料噴射を行なう３回噴射の際に１回目を全開噴射で燃料噴射を行なうと共に２回目と３回目とを部分噴射で燃料噴射を行なうときに、全燃料噴射量と３回目の燃料噴射量とを設定し、１回目の燃料噴射量と２回目の燃料噴射量については全燃料噴射量から３回目の燃料噴射量を減じた値に分割割合を乗じて設定する。この際、２回目の燃料噴射量が部分噴射におる最大燃料噴射量以下となるように、１回目の燃料噴射量と２回目の燃料噴射量とを設定する。【選択図】図２
