摘要： A controller of an internal combustion engine receives a request to activate an exhaust brake subsystem and, in response thereto, activates the exhaust braking subsystem. The controller thereafter determines that at least one parameter of the exhaust system, an intake subsystem or both compares unfavorably with at least one threshold. When the at least one parameter compares unfavorably with the at least one threshold, the controller determines that the exhaust braking subsystem has failed. In embodiments, the determination that the at least one parameter compares unfavorably with the at least one threshold comprises a determination that backpressure in the exhaust system is lower than a backpressure threshold and/or a determination that boost pressure in the intake subsystem is higher than a threshold.

摘要： Systems for actuating at least two engine valves comprise a valve bridge operatively connected to the at least two engine valves and having a hydraulically-actuated lost motion component. The lost motion component comprises a lost motion check valve disposed therein. A rocker arm has a motion receiving end configured to receive valve actuation motions from a valve actuation motion source and a motion imparting end for conveying the valve actuation motions and hydraulic fluid to the lost motion component. The rocker arm is in fluid communication with a hydraulic fluid supply. The systems also comprise an accumulator in fluid communication with the hydraulic fluid supply and disposed upstream of the lost motion check valve. In all embodiments, a fluid supply check valve may be disposed upstream of the accumulator and configured to prevent flow of hydraulic fluid from the accumulator back to the hydraulic fluid supply.

摘要： Engine valve actuation systems and methods used to decompress an engine cylinder during engine start-up, shut-down, and for bleeder braking are disclosed. An exemplary system may include a rocker arm pivotally mounted on a rocker shaft, and a structure mounted adjacent to the rocker arm in a fixed position relative to the rocker arm. A latch piston may be slidably disposed between the rocker arm and the structure. The latch piston may be selectively extended to engage both the rocker arm and structure to limit the pivotal motion of the rocker arm and maintain the engine valves in an open condition.
