Summary:To inhibit an oil from being heated to a high temperature in an engine device which performs oil jetting in which the oil is jetted to a piston of an engine.SOLUTION: An engine device includes: an engine; an oil jet mechanism which jets an oil for lubricating the engine to a piston; and a control device which controls the engine. The control device significantly limits an engine load when a temperature of the oil lubricating the engine is high compared to when the temperature of the oil is low. The action inhibits the oil from being heated to a high temperature and prevents a trouble that an oil pressure is decreased by the oil being heated to the high temperature to hinder oil jetting, in which the oil is jetted to the piston to cool the piston, from being performed effectively.SELECTED DRAWING: Figure 3 【課題】エンジンのピストンにオイルを噴射するオイルジェットを行なうエンジン装置において、オイルが高温になるのを抑制する。【解決手段】エンジン装置は、エンジンと、エンジン潤滑するオイルをピストンに噴射するオイル噴射機構と、エンジンを制御する制御装置と、を備える。制御装置は、エンジン潤滑するオイルの温度が高いときには低いときに比してエンジン負荷を大きく制限する。これにより、オイルが高温になるのを抑制することができ、オイルが高温になることによって油圧が低下し、ピストンにオイルを噴射してピストンを冷却するオイルジェットを良好に行なうことができないという不都合を抑制することができる。【選択図】図３
