Abstract: Systems for, and methods of, controlling exhaust gas temperature in a multicylinder internal combustion engine during positive power operation of the engine. Control of exhaust gas temperature may be desired to improve emissions performance in the engine. One or more temperature probes may be used to first determine the actual exhaust gas temperature of the engine during positive power operation. 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, causing the actual exhaust gas temperature to change and more closely match the desired exhaust gas temperature.

Abstract: 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.
Abstract translation: 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。

Abstract: Systems and methods for hydraulic and/or variable valve actuation of engine valves are disclosed. An embodiment of the present invention may include a hydraulic valve actuation system operatively connected to an engine valve. First and second control valves may be operatively connected to the hydraulic valve actuation system and adapted to selectively release hydraulic fluid from the hydraulic valve actuation system independent of one another. The first control valve is preferably a solenoid actuated trigger valve and the second control valve is preferably a mechanically or hydraulically actuated valve.
