PROBLEM TO BE SOLVED: To provide a hybrid vehicle including a port injection-type engine, with the startability of the engine improved in the case of an engine start request being made while the deterioration of emission suppressed.SOLUTION: An engine 100 is incorporated in a vehicle 1 configured to enable an EV travel. The engine 100 includes: a port injection valve 550 for injecting fuel into an intake port 130; a low-pressure delivery pipe 540 for reserving the fuel for injecting it from the port injection valve 550; and a feed pump 512 for supplying the low-pressure delivery pipe 540 with the fuel pressurized. An ECU 300 performs: starting the feed pump 512 in a case where a pump threshold Pr1 is exceeded by vehicular requirement power P that is drive power required of the vehicle 1 by a user; and generating a start request for the engine 100 in a case where an engine threshold Pr2 that is larger than the pump threshold Pr1 is exceeded by the vehicular requirement power P.SELECTED DRAWING: Figure 4

    【課題】ポート噴射タイプのエンジンを備えるハイブリッド車両において、エンジン始動要求が発生した場合に、エミッションの悪化を抑制しつつエンジンの始動性を向上させる。【解決手段】エンジン100は、EV走行が可能に構成された車両1に搭載される。エンジン100は、吸気ポート130に燃料を噴射するポート噴射弁550と、ポート噴射弁550から噴射するための燃料を貯留する低圧デリバリーパイプ540と、燃料を加圧して低圧デリバリーパイプ540に供給するフィードポンプ512と、を備える。ECU300は、EV走行において、ユーザが車両1に要求する駆動パワーである車両要求パワーPがポンプしきい値Pr1を上回った場合に、フィードポンプ512を始動し、車両要求パワーPがポンプしきい値Pr1よりも大きいエンジンしきい値Pr2を上回った場合に、エンジン100の始動要求を発生する。【選択図】図4
