    Abstract: The claimed method and system provide a process control device monitoring system and a process control valve assembly with a process control device monitoring system to measure one or more operating states of a process control device. The process control device monitoring system may also associate a time- stamp with the one or more measured operating states of the process control device in response to a trigger generated based on the one or more measured operating states. The process control device monitoring system may also transmit the time- stamp and an indication of the one or more operating states to a monitoring device.

    Abstract: A system for monitoring operation and diagnosing malfunctions in a variable valve actuation device is disclosed. The system has a rocker arm assembly that includes a first arm, a second arm with the first and second arms attached at a first end, a hydraulically operated latch assembly that functions to secure the first arm to the second arm when latched. The latch may be operated by a remote device. The rocker assembly pivots on a hydraulic lash adjuster (HLA). A control gallery connects the hydraulic valve to the latch. A pressure transducer is positioned either in the control gallery or the HLA and creates a signal indicating the sensed pressure. A reads the signal from the pressure transducer and identifies malfunctions of the rocker arm assembly. The system may also employ a non-contact transducer that monitors the state of the rocker arm assembly. The system may also employ a valve stem position sensor that monitors the engine valve position to determine malfunctions of the rocker arm assembly.

    Abstract: 一种监控燃气品质的方法及装置,该方法包括获取空气体积流量和燃气体积流量(S101);判断空气体积流量和燃气体积流量的比值是否大于预设阈值(S102);若是,则确定燃气品质发生变化,且具有爆震倾向(S103)。该方法通过实时监测空气体积流量和燃气体积流量,通过计算出二者的比值与安全阈值相比较,以方便快捷地判断出是否具有爆震倾向,进而可快速采用相应的抑制爆震操作,抑制爆震的产生。该监控燃气品质的方法通过监测气源品质进行预测爆震,甚至不用安装爆震传感器等部件,也极大程度地降低了开发成本。

    Abstract: In one aspect of the invention, an engine is operated in a skip cylinder engine braking mode. In the skip cylinder engine braking mode, selected working cycles of selected working chambers are deactivated. Other selected working cycles of the selected working chambers are operated in a braking mode. Accordingly, individual working chambers are sometimes deactivated and sometimes operated in the braking mode while the engine is operating in the skip cylinder engine braking mode. Various methods for cylinder control are described, which improve fuel economy, catalytic converter performance, and vehicle NVH characteristics.
