摘要： Valve bridge systems include constraints and guides for managing bridge jump and other uncontrolled valve bridge motion during engine operation. Constraints may include an e-foot collar, an extended portion on the bridge, and a bridge brake pin. Guides may include valve stem tip lead-in chamfers surrounding the valve bridge valve pockets as well as a deflection surface on the bridge extended portion. Methods of configuring valve bridges may include configuring the valve step tip lead-in chamfers based on worst-case positions of the valve bridge defined by one or more or a combination of the constraints provided by the e-foot collar, extended portion and brake pin.

摘要： A valve actuation system comprises a valve actuation motion source configured to provide a main valve actuation motion and an auxiliary valve actuation motion for actuating at least one engine valve via a valve actuation load path. A lost motion subtracting mechanism is arranged in a pre-rocker arm valve train component and configured, in a first default operating state, to convey at least the main valve actuation motion and configured, in a first activated state, to lose the main valve actuation motion and the auxiliary valve actuation motion. Additionally, a lost motion adding mechanism is arranged in a valve bridge and configured, in a second default operating state, to lose the auxiliary valve actuation motion and configured, in a second activated state, to convey the auxiliary valve actuation motion, wherein the lost motion adding mechanism is in series with the lost motion subtracting mechanism in the valve actuation load path.

摘要： A system for controlling actuation of an engine valve comprises a pivot and a torsion spring having first and second legs operatively connected to the pivot. A lever arm is adjustably affixed to and extending away from the pivot, and is further rotatable about a pivot axis of the pivot between a retracted position and an extended position and vice versa relative to a motion conveying component. Furthermore, a housing is provided having a pivot bore formed therein with the pivot rotatably disposed in the pivot bore. The housing further comprises a first and second openings intersecting with the pivot bore such that the first and second legs extend out of the first opening and the lever arm extends out of the second opening. When a first force is applied by the motion conveying component to the lever arm, such first force maintains the lever arm in the extended position.

摘要： 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.

摘要： In an internal combustion engine comprising two or more engine valves that receive valve actuation motions from a valve actuation motion source via a valve train, which valve train comprises a hydraulic lash adjuster, an apparatus for valve actuation comprises a valve bridge and a lost motion assembly disposed therein. The lost motion assembly comprises a first piston disposed in a first piston bore formed in the valve bridge. The first piston is configured to operatively connect with a component of the valve train. A biasing element is configured to bias the first piston out of the first piston bore with a first force that is greater than a second force applied to the first piston by the hydraulic lash adjuster. A travel limiter is configured to limit travel of the first piston out of the first piston bore to be no greater than a maximum lost motion distance.

摘要： A method and system for actuating an internal combustion engine exhaust vaive to provide compression release actuation during an engine braking mode of engine operation and early exhaust valve opening actuation during a positive power mode of engine operation is disclosed. The system may include a first cam having a compression release lobe and an early exhaust valve opening lobe connected to a hydraulic lost motion system including a first rocker arm. A hydraulically actuated piston may be selectively extended from the hydraulic lost motion system to provide the exhaust valve with compression release actuation or early exhaust valve opening actuation. The hydraulicaily actuated piston may be provided as a slave piston in a master-slave piston circuit in a fixed housing, or alternatively, as a hydraulic piston slidably disposed in a rocker arm. The method and system may further provide exhaust gas recirculation and/or brake gas recirculation in combination with compression release actuation and early exhaust valve opening actuation.

摘要： Systems for, and methods of, controlling exhaust gas temperature in a multi-cylinder internal combustion engine during positive power operation of the engine are disclosed. Control of exhaust gas temperature may be desired to improve emissions performance in the engine, which is often dependent upon exhaust gas temperature. One or more temperature probes may be used to first determine the actual exhaust gas temperature of the engine while it is operated in a positive power mode. Next, an ECM or similar device may be used to determine a temperature difference between the actual exhaust gas temperature and a desired exhaust gas temperature for emissions performance. Based on the determined temperature difference, one or more cylinders of the engine may continue to be operated in positive power mode while one or more cylinders of the engine are switched to operating in a selected engine braking mode. The operation of some cylinders in positive power mode while operating other cylinders in engine braking mode may cause the actual exhaust gas temperature to change and more closely match the desired exhaust gas temperature.
摘要翻译：公开了在发动机的正功率运行期间控制多气缸内燃机中的排气温度的系统和方法。可能需要控制排气温度以改善发动机中的排放性能，这通常取决于废气温度。可以使用一个或多个温度探测器来首先确定发动机在正功率模式下的实际排气温度。接下来，可以使用ECM或类似装置来确定实际废气温度和用于排放性能的期望废气温度之间的温差。基于所确定的温度差，发动机的一个或多个气缸可以继续以正功率模式操作，同时将发动机的一个或多个气缸切换到以所选择的发动机制动模式操作。在发动机制动模式下操作其他气缸时，正功率模式下的某些气缸的运行可能导致实际废气温度发生变化，并且更符合所需的废气温度。
