Claims (1)
- 発電機に一定の周波数の起電力を生じさせるために目標回転数が一定に設定される発電機用内燃機関において、
燃料を噴射する燃料噴射装置と、
機関の実際の回転数である実回転数を検出する回転数検出部と、
前記燃料噴射装置の噴射時期を制御する制御部と、
を備え、
前記制御部には、
前記実回転数の値に基づいて判定される過渡期において前記噴射時期を制御するための情報である過渡期噴射時期制御情報と、
前記過渡期噴射時期制御情報により得られた噴射時期を補正するために、前記目標回転数と前記実回転数との回転数差の大きさに応じて設定されている補正情報と、
が記憶されており、
前記制御部は、
前記目標回転数と前記実回転数との偏差を計算し、
前記偏差の絶対値と、当該偏差の絶対値の上限値(閾値)である許容乖離量とを比較し、前記偏差の絶対値が許容乖離量以上であって、その状態が所定の判定回以上継続していた場合、前記過渡期であると判定し、
前記過渡期であると判定した場合、前記燃料噴射装置の前記噴射時期を、前記補正情報による補正後の噴射時期となるように制御し、前記実回転数が前記目標回転数より小さい場合、前記噴射時期を進角させるように補正し、前記実回転数が前記目標回転数より大きい場合、前記噴射時期を遅角させるように補正することを特徴とする発電機用内燃機関。
