To extend a service life of a piston.SOLUTION: An ECU 200 includes a temperature acquisition section 21 for acquiring a temperature of a piston 9, a condition determination section 22 for determining whether or not a variation amount of the piston 9 satisfies any of a first condition or a second condition determined in advance, and an injection amount control section 23 for reducing an injection amount of oil injected from an oil jet 13 by reducing an oil pressure when any of the first condition or the second condition is satisfied.SELECTED DRAWING: Figure 2 【課題】ピストンの寿命を延ばすこと。【解決手段】ＥＣＵ２００は、ピストン９の温度を取得する温度取得部２１と、ピストン９の温度の変化量が、予め定められた第１条件または第２条件のいずれかを満たしたか否かを判定する条件判定部２２と、第１条件または第２条件のいずれかが満たされた場合、油圧を低下させることによりオイルジェット１３から噴射されるオイルの噴射量を低減させる噴射量制御部２３と、を有する。【選択図】図２
