    Abstract: 【課題】液化ガス燃料を使用する内燃機関を搭載したハイブリッド車両に対し、運転者の加速要求に応じた駆動力を得ることが可能なハイブリッド車両の制御装置を提供する。【解決手段】LPG燃料を使用するエンジン1を搭載したハイブリッド車両において、EV走行中、燃料ポンプ10eが停止し且つ燃料還流管10fに備えられた電磁弁10iが閉鎖している状態で、アクセル開度が所定値に達すると、電磁弁10iを開放すると共に燃料ポンプ10eを作動させ、デリバリパイプ10b内の燃料を燃料還流管10fに排出し、燃料供給管10cおよび燃料タンク10dの比較的低温の燃料をデリバリパイプ10b内に流入させる。さらにアクセル開度が大きくなって、エンジン始動要求が生じるとエンジン始動動作を実行する。これにより、エンジン始動時に気相燃料が噴射されることが回避され、運転者の車両加速要求に応じたドライバビリティを得ることができる。【選択図】図2

    Abstract: PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of properly discharging oxygen from a three-way catalyst when starting an engine, even when a power mode is selected.
    SOLUTION: An electronic control unit 22 is provided with a normal mode, and a power mode wherein control characteristics are set so as to make a throttle opening larger as compared with the normal mode, as modes for deciding the control characteristics of a throttle valve 15 to accelerator operation amount. The electronic control unit 22 increases fuel injection amount when starting the engine to temporary make an air/fuel ratio rich, and discharges oxygen occluded by the three-way catalyst 21 for exhaust emission control during the stopping of the engine. The electronic control unit 22 controls the throttle valve 15 by the control characteristics of the normal mode, until a regular period has passed since the engine starts, even if the power mode is set.

    Abstract: PROBLEM TO BE SOLVED: To inhibit excess supply of fuel at a time of start of an internal combustion engine. SOLUTION: An automobile 20 is provided with an engine 22 provided with a cylinder fuel injection valve 25 connected to a delivery pipe 66 provided with a fuel pressure sensor 69 and injecting fuel supplied by a fuel pump 62. The automobile 20 improves startability of the engine 22 by driving a fuel pump 62 before driving a high pressure pump 64 and performing pre-supply process supplying fuel to the high pressure pump 64 when it is judged that fuel does not leak from the cylinder fuel injection valve 25 at a time of start of the engine 22. On the other hand, the pre-supply process is not performed to inhibit fuel leak from the cylinder fuel injection valve 25 when it is judged that fuel leaks from the cylinder fuel injection valve 25.

    Abstract: PROBLEM TO BE SOLVED: To display information on fuel that has been consumed not in traveling.
    SOLUTION: In an automobile provided with an air-conditioner for heating a cabin with an engine as the heat source, fuel consumed by the engine is computed as fuel consumed not for traveling, when the cabin is heated by the air conditioner, the engine is running, and the vehicle is parked. The computed fuel is displayed as the fuel consumption of air-conditioning in parallel with the amount of fuel consumed by the overall vehicle on a display installed in the cabin. It is thereby possible to notify the driver and the passengers, of the amount of fuel consumed not for traveling, after comparing with the amount of fuel consumed by the vehicle as a whole.
