Description
このような燃料噴射ポンプの噴射タイミング調整制御システムによれば、何らかの原因で電空変換器および／または圧力トランスミッタに異常が生じ、かつ、流路切替弁にも異常が生じた場合、第１のエアコックを（手動で）閉から開とし、第２のエアコックを（手動で）開から閉とすることにより、空気槽から送出されるとともに、圧力調整弁にて所定の圧力に調整された制御空気が、流路切替弁を通らずに、バックアップライン、バイパスライン、および流路切替弁よりも下流側に位置する制御空気ラインを介してタイミングラックアクチュエータに導かれることになる。
これにより、電空変換器および／または圧力トランスミッタに異常が生じ、かつ、流路切替弁に異常が生じた場合でも、圧力調整弁にて所定の圧力に調整された制御空気をタイミングラックアクチュエータに導くことができ、当該燃料噴射ポンプの噴射タイミング調整制御システムの信頼性（安全性）を向上させることができる。
According to the fuel injection pump injection timing adjustment control system, abnormality occurs in the pneumatic transducer and / or pressure transmitters collector for some reason, and, if an abnormality occurs in the flow path switching valve, a first Control air that is sent from the air tank and adjusted to a predetermined pressure by the pressure adjustment valve by switching the air cock (manually) from open to open and the second air cock (manually) from open to closed However, it does not pass through the flow path switching valve, but is guided to the timing rack actuator through the backup line, the bypass line, and the control air line located downstream of the flow path switching valve.
Thereby, abnormality occurs in the electropneumatic transducer and / or pressure transmitter, and, even if an abnormality occurs in the flow path switching valve, the control air is adjusted to a predetermined pressure by the pressure regulating valve to a timing rack actuator Therefore, the reliability (safety) of the injection timing adjustment control system of the fuel injection pump can be improved.
また、本実施形態に係る燃料噴射ポンプの噴射タイミング調整制御システム５０によれば、何らかの原因で電空変換器１６および／または圧力トランスミッタ３２に異常が生じ、かつ、流路切替弁３３にも異常が生じた場合、第１のエアコック５２を手動で閉から開とし、第２のエアコック５３を手動で開から閉とすることにより、空気槽１７から送出されるとともに、圧力調整弁３４にて所定の圧力に調整された制御空気が、流路切替弁３３を通らずに、バックアップライン３１、バイパスライン５１、および流路切替弁３３よりも下流側に位置する制御空気ライン１８を介してタイミングラックアクチュエータ１４に導かれることになる。
これにより、電空変換器１６および／または圧力トランスミッタ３２に異常が生じ、かつ、流路切替弁３３に異常が生じた場合でも、圧力調整弁３４にて所定の圧力に調整された制御空気をタイミングラックアクチュエータ１４に導くことができ、当該燃料噴射ポンプの噴射タイミング調整制御システム５０の信頼性（安全性）を向上させることができる。
Further, according to the fuel injection pump of the injection timing adjustment control system 50 according to the present embodiment, abnormality occurs in the pneumatic transducer 16 and / or pressure transmitter 32 conductive for some reason, and also to the flow path switching valve 33 abnormal Is generated, the first air cock 52 is manually opened from the closed state, and the second air cock 53 is manually opened from the closed state. The control air adjusted to the pressure of the timing rack does not pass through the flow path switching valve 33, but passes through the backup line 31, the bypass line 51, and the control air line 18 located downstream of the flow path switching valve 33. It will be guided to the actuator 14 .
Thus, empty abnormality occurs in the transducer 16 and / or pressure transmitter 32 conductive and, even if the abnormality in the flow path switching valve 33 has occurred, the control air is adjusted to a predetermined pressure by the pressure regulating valve 34 It can be guided to the timing rack actuator 14 and the reliability (safety) of the injection timing adjustment control system 50 of the fuel injection pump can be improved.
