Description
<電圧印加時間Tpの補正>
本実施例に係る燃料噴射弁制御装置は、図3に示すように、電圧印加時間補正手段341を備える。この電圧印加時間補正手段341による補正の効果を図5に基づいて説明する。なお、図5は、電圧印加時間Tpのみを燃料噴射装置A、B、Cごとに変えた場合の説明図である。昇圧電圧印加時間補正手段341は、図5の上図のように、セットスプリング力Fspが小さい燃料噴射弁Cでは、電圧印加時間Tpを標準値より短い電圧印加時間TpCに補正する。また、スプリング力Fspが大きい燃料噴射装置Aへの電圧印加時間は、標準値より大きい電圧印加時間TpAに補正する。この電圧印加時間補正手段341により、弁リフトのピークの時刻が図5の中央の図のように揃う。また、駆動パルス幅Tiに対する噴射量特性は図5の下図のようになり、噴射量特性の平坦部が揃う。
<隙間時間T2の補正>
本実施例に係る燃料噴射弁制御装置は、図3に示すように、電圧Vboostを打ち切ってから次にバッテリー電圧を与えるまでの隙間時間T2を補正する隙間時間補正手段342を備える。この隙間時間補正手段342による補正の効果を図6に基づいて説明する。なお、図6は、上述した電圧印加時間補正手段341によって既に電圧印加時間Tpが補正された状態において、さらに隙間時間T2を燃料噴射装置A、B、Cごとに変えた場合の説明図である。
<保持電流Ihの補正>
本実施例に係る燃料噴射弁制御装置は、図3に示すように、保持電流Ihを補正する保持電流補正手段343を備える。この保持電流補正手段343による補正の効果を図7に基づいて説明する。なお、図7は、上述した電圧印加時間補正手段341及び隙間時間補正手段342によって既に昇圧電圧印加時間Tp及び隙間時間T2が補正された状態において、さらに保持電流Ihを燃料噴射装置A、B、Cごとに変えた場合の説明図である。
なお、本発明に係る燃料噴射弁制御装置は、上記実施形態に限定されるものではなく、その趣旨を逸脱しない範囲において適宜その構成を変更することができる。
