Claims (1)
- 水冷式4サイクルエンジンのクランクシャフトを略垂直に配置し、シリンダヘッドに形成される各気筒の吸気ポートと連通する吸気マニフォールドをシリンダブロックの側面に上下方向に配列させると共に、燃料タンク内の燃料を一旦ベーパーセパレータに導いた後、フューエルインジェクタを用いて上記エンジンに供給する船外機において、
上記ベーパーセパレータ内に高圧燃料ポンプを配置して上記フューエルインジェクタに燃料ホースを介して燃料を圧送すると共に、上記エンジンのシリンダブロックの側面と上記吸気マニフォールドとの間に形成されるスペースに上記ベーパーセパレータを配置し、このベーパーセパレータを上記吸気マニフォールドの内側に固定する一方、
上記高圧燃料ポンプと上記フューエルインジェクタの途中に分岐部を設け、この分岐部からベーパーセパレータに延びる戻り燃料ホースの途中に、エンジン冷却用の冷却水を導いて燃料を冷却する燃料クーラを配置すると共に、
上記吸気マニフォールドの外側に取り付けられるデリバリパイプと上記吸気マニフォールドのシリンダヘッドへの取り付け部分との間に形成されるスペースに上記燃料クーラを配置し、この燃料クーラを上記吸気マニフォールドの外側に固定したことを特徴とする船外機の燃料冷却装置。
