Description
プランジャ34が下降し、加圧室42内の圧力が低下することに基づいて、低圧室40から加圧室42へ燃料が吸入される。そして、ECU90により、開弁状態を保持するように調量弁36が制御される。
調量弁36が開いた状態では、プランジャ34が下死点から上死点に向かって上昇しても、プランジャ34により加圧された加圧室42内の燃料は、調量弁36を介して低圧室40へ戻される。
戻し行程中に、ECU90により、閉弁するように調量弁36が制御される。この状態でプランジャ34がさらに上死点に向けて上昇すると、加圧室42内の燃料が加圧され燃料の圧力が上昇する。そして、加圧室42内の燃料の圧力が所定の吐出圧以上になると吐出弁38が開く。吐出弁38から吐出された燃料は、デリバリパイプ60へ供給されて加圧状態で蓄えられ、燃料噴射弁62へ供給される。
・リリーフ弁80の開弁圧よりも低く設定された異常判定圧よりも高い状態が第1期間よりも長く続いた場合に、エンジン10のアイドル回転速度を800rpmや1200rpmまで上昇させてもよい。
