Abstract
Description
以下、内燃機関の燃料供給装置の第1実施形態を、図1〜図7を参照して詳細に説明する。
上記のような作動音抑制制御が実施されると、第2バンク10Bの高圧燃料ポンプ20Bの電磁弁28の開閉が休止されるため、燃料吐出部全体の電磁弁28の開閉頻度は通常制御時の半分となる。そのため、燃料吐出部全体としての電磁弁28の開閉頻度が低下され、その開閉による作動音が小さくなる。ただし、開閉頻度が減った分、電磁弁28の開閉毎の燃料吐出量が増加するため、燃圧の脈動は大きくなる。
(1)本実施形態では、パーシャルリフト噴射が行われていないときに限り、燃圧脈動の増大を招く作動音抑制制御が実施される。そのため、燃焼の悪化を抑えつつ、電磁弁28の作動音を抑制することができる。
上記実施形態では、燃料加圧部が備える2基の高圧燃料ポンプ20A,20Bのうちの1基の加圧動作(電磁弁28の開閉)を休止することで、作動音抑制制御を行うようにしていた。こうした作動音抑制制御は、これとは別の態様で行うことも可能である。
・図4の作動音抑制制御実施判定ルーチンのステップS100では、内燃機関がアイドル運転中であること、車速SPDが規定車速以下であること、の少なくとも一方が成立したときに電磁弁28の作動音抑制の必要有りと判定していた。こうした判定の具体的な条件の内容は適宜変更してもよい。要は、内燃機関が低負荷運転されていて要求される燃料吐出量が少ない状態にあり、且つ内燃機関の発生音や車両の走行音が全体的に小さくて電磁弁28の作動音が際立つ状況にあるときに成立するような条件であれば良い。
Claims (3)
