Zusammenfassung:	To protect an ECU for controlling an engine from heat.SOLUTION: In an engine comprising an ECU (100) that controls an engine (E), a thermo switch (73) is provided near the ECU (100); when the thermo switch (73) detects a temperature above a predetermined value, the thermo switch (73) is turned on; and when the thermo switch (73) is turned on after the engine is started, a fuel injection amount is changed to a smaller amount than a required fuel injection amount.SELECTED DRAWING: Figure 7 【課題】エンジンを制御するＥＣＵを熱から保護することを課題とする。【解決手段】エンジン（Ｅ）を制御するＥＣＵ（１００）を備えたエンジンにおいて、ＥＣＵ（１００）の近くにサーモスイッチ（７３）を設け、該サーモスイッチ（７３）が所定値以上の温度を検出するとサーモスイッチ（７３）が入り状態となる構成とし、エンジン始動後に前記サーモスイッチ（７３）が入り状態になると、要求される燃料噴射量よりも少ない燃料噴射量に変更することを特徴とする作業車両の構成とする。【選択図】図７
