Abstract
(EN)
Provided is a work machine wherein, when a reproduction requirement determination unit determines that reproduction of a collecting section is required, a load control unit controls a pressure accumulation unit and makes the pressure accumulation unit accumulate engine output as pressurized oil energy from a hydraulic oil pump and, thereby, increases the load on the engine and, once the pressurized oil energy has been accumulated to the upper pressure accumulation limit for the pressure accumulation unit, the load control unit controls an electricity storage unit and makes the electricity storage unit store the engine output as electrical energy generated by a generator and, thereby, increases the engine load.
(FR)
L'invention concerne un engin de mise en œuvre dans lequel, quand une unité de détermination de demande de reproduction détecte que la reproduction d'une section de collecte est requise, une unité de commande de charge commande une unité d'accumulation de pression pour qu'elle accumule la puissance du moteur sous forme d'énergie d'huile sous pression provenant d'une pompe hydraulique et, de ce fait, augmente la charge sur le moteur et, une fois qu'on a accumulé de l'énergie d'huile sous pression jusqu'à la limite supérieure d'accumulation de pression pour l'unité d'accumulation de pression, l'unité de commande de charge commande une unité de stockage d'électricité pour qu'elle accumule la puissance du moteur sous forme d'énergie électrique produite par un générateur et, de ce fait, augmente la charge sur le moteur.
(JA)
 作業機械は、再生要否判断部によって捕集部の再生が必要であると判断されると、負荷制御部は、蓄圧部を制御して、エンジンの出力を油圧ポンプからの圧油のエネルギとして蓄圧部に蓄圧させることによってエンジンの負荷を増加させ、圧油のエネルギが蓄圧部での蓄圧の上限まで蓄圧された後、負荷制御部は、蓄電部を制御して、エンジンの出力を発電機によって発電された電気エネルギとして蓄電部に蓄電させることによってエンジンの負荷を増加させる。
