Summary:PROBLEM TO BE SOLVED: To enable a gaseous fuel injection control device to be applied for controlling an injection timing of gaseous fuel at an engine showing various layouts.SOLUTION: A gaseous fuel injection control device of this invention comprises: a stage calculating part for calculating a stage that is a period where one cycle of an engine for igniting gaseous fuel is divided for every cycle; and a gaseous fuel injection starting timing calculation part for calculating a stage for starting injection of gaseous fuel and a time ranging from the stage starting to the gaseous fuel injection starting on the basis of a gaseous fuel injection finish timing from a gaseous fuel injection valve toward a cylinder, an engine speed of the engine and a gaseous fuel injection time toward the cylinder. 【課題】気体燃料噴射制御装置を様々なレイアウトのエンジンにおける気体燃料の噴射タイミングの制御に適用できるようにする。【解決手段】気体燃料噴射制御装置が、気体燃料を燃焼させるエンジンの1サイクルを分割した期間であるステージをシリンダ毎に算出するステージ算出部と、気体燃料噴射弁からシリンダに向けての気体燃料の噴射の終了タイミングと、前記エンジンの回転数と、シリンダに向けての気体燃料の噴射時間とに基づいて、気体燃料の噴射を開始するステージと、当該ステージ開始から当該気体燃料の噴射開始までの時間とを算出する、気体燃料噴射開始タイミング算出部と、を具備する。【選択図】図1
