Shovel having an engine equipped with a supercharger
A shovel includes a boom cylinder that drives a boom and an arm cylinder that drives an arm. A hydraulic pump supplies operating oil to the boom cylinder and the arm cylinder. An engine is connected to the hydraulic pump and equipped with a supercharger. The engine is controlled to maintain a revolution speed within a certain definite range. A controller controls a rotating speed of the supercharger. The controller performs a process of increasing the rotating speed of the supercharger so as to increase a supercharging pressure generated by the supercharger before a hydraulic load is applied to the engine.
