Zusammenfassung:	PROBLEM TO BE SOLVED: To enable gaseous fuel within a fuel tank to be fully used as much as possible at a low cost without making a size of vehicle 1 large.SOLUTION: A gaseous fuel engine control device mounted on a vehicle is provided that comprises pressure detection means for detecting a pressure in fuel tanks (a hydrogen tank 70 and a CNG tank 71), temperature detection means for detecting a temperature in the fuel tanks and control means (a control unit 100) for controlling an operation of an engine 10.The control means performs an exhaust gas heat increasing control for increasing the exhaust gas heat of the engine 10 when a condition is fulfilled that a pressure in the fuel tank detected by the pressure detection means is a prescribed pressure or less and a temperature in the fuel tank detected by the temperature detection means becomes a prescribed temperature or less, so that the fuel tank is heated by the exhaust gas flow passing through near the fuel tank.SELECTED DRAWING: Figure 1 【課題】車両１を大型化することなく、低コストで、燃料タンク内の気体燃料を出来る限り使い切れるようにする。【解決手段】燃料タンク（水素タンク７０，ＣＮＧタンク７１）内の圧力を検出する圧力検出手段と、上記燃料タンク内の温度を検出する温度検出手段と、エンジン１０の作動を制御する制御手段（コントロールユニット１００）とを備え、上記制御手段は、上記圧力検出手段による上記燃料タンク内の圧力が所定圧以下でかつ上記温度検出手段による上記燃料タンク内の温度が所定温度以下になるという条件が成立したときに、エンジン１０の排気熱を増大させる排気熱増大制御を実行することで、上記燃料タンクの近傍を通る排気流により該燃料タンクを加温する。【選択図】図１
