Title
(EN) Engine system
(ZH) 发动机系统
Abstract
(EN)
Provided is an engine system capable of ensuring sufficient boost pressure during engine braking, and improving the braking force of compression release brakes. The engine system is provided with: a compression release brake device (19) for operating a compression release brake which obtains braking force during engine braking by forcibly opening an exhaust valve (24) and releasing compressive pressure near compression top dead centre of an (E) engine; an electric assist turbocharger (2) having a turbine (3) disposed on the exhaust passage (6) of the engine and driven by the exhaust, a compressor disposed on the intake passage (7) and driven by the rotational torque of the turbine (3), and an electric motor (5) which assists the drive force of the compressor (4); and an electric motor control unit (22) which drives the electric motor (5) when the compression release break is operating.
