    • A controller of an internal combustion engine receives a request for engine braking and, in response thereto, activates an exhaust braking subsystem. Additionally, after passage of a period of time, the controller further activates a compression release braking subsystem. The period of time is preferably selected to permit development of increased back pressure in an exhaust system of the internal combustion engine prior to activation of the compression release braking subsystem. Additionally, following activation of the exhaust braking subsystem, the controller may whether the exhaust braking subsystem has failed and, if so, cause the compression release braking subsystem to operate in a reduced braking power mode, for example at less than full braking power potentially down to and including no braking power.
    • 内燃机的控制器接收发动机制动的请求,响应于此,启动排气制动子系统。 此外,经过一段时间后,控制器进一步激活压缩释放制动子系统。 该时间段优选地被选择为允许在启动压缩释放制动子系统之前在内燃机的排气系统中开发增加的背压。 此外,在激活排气制动子系统之后,控制器可以判断排气制动子系统是否发生故障,如果是这样,则使压缩释放制动子系统以降低的制动功率模式工作,例如低于完全制动功率可能会下降 包括无制动力。

    • The invention relates to a method for operating a reciprocating internal combustion engine in an engine braking mode. In said method, in a working cycle of the engine braking mode, at least one outlet valve of at least one cylinder is closed (1S1, 1S1", 1S1'") for a first time, then opened (1O1, 1O1", 1O1"') for a first time and subsequently closed (2S1, 2S1', 2S1", 2S1'") for a second time and then opened (2O1, 2O1", 2O1'") for a second time in order to thereby discharge compressed gas contained in the cylinder from said cylinder by means of a cylinder piston. The outlet valve is held open after the first opening operation (1O1, 1O1", 1O1") and prior to the second closing operation (2S1, 2S1', 2S1", 2S1'") long enough for the cylinder to be filled with gas that flows out of at least one second cylinder of the reciprocating internal combustion engine via at least one outlet channel.
