Abstract

An engine system for ensuring a sufficient boost pressure during engine braking and improving a braking force of a compression release brake. The system includes: a compression release brake device that operates a compression release brake to obtain a braking force during engine braking by forcibly opening an exhaust valve and releasing a compressive pressure near a compression top dead center of an engine; a power-assisted turbocharger including a turbine disposed on an exhaust passage of the engine and driven by exhaust, a compressor disposed on an intake passage and driven by a rotational torque of the turbine, and an electric motor that assists a drive force of the compressor; and an electric motor control unit that drives the electric motor when the compressor release brake is operated.
