    • A method and system of misfire determination includes establishing an acceleration misfire threshold and an acceleration sub-misfire threshold. Then incremental engine position is sensed and a series of acceleration data-points are derived (401). If a data-point of the series of acceleration data-points falls between the sub-misfire threshold and the misfire threshold, then a training process is aborted for a blanking period based on a delay time whose length is preferably based on engine operating conditions (415). If a data-point of the series of acceleration data-points does not fall below the sub-misfire threshold, then the series of acceleration data-points, are averaged and a synchronously corrected acceleration data-point is derived (417). Then, a misfire condition is indicated when the synchronously corrected acceleration data-point exceeds the established acceleration misfire threshold (421).
    • 失火判定的方法和系统包括建立加速失火阈值和加速度失火阈值。 然后检测出增量发动机位置,得到一系列加速度数据点(401)。 如果一系列加速度数据点的数据点落在子失火阈值和失火阈值之间,则基于其长度优选地基于发动机操作条件的延迟时间而在消隐周期中中止训练过程( 415)。 如果一系列加速度数据点的数据点不低于次失火阈值,则对一系列加速度数据点进行平均,并导出同步校正的加速度数据点(417)。 然后,当同步校正的加速度数据点超过建立的加速失火阈值时,指示失火条件(421)。

    • A non-synchronous camshaft phasing device 46 for use with an internal combustion engine E. The internal combustion engine E includes an engine control unit ECU, a camshaft 42 and a crankshaft 12. The non-synchronous phasing device 46 is located between the crankshaft 12 and the camshaft 42 for controlling a phase shift angle between the camshaft 42 and the crankshaft 12. The phasing device 46 comprises an input shaft 36 coupled to the crankshaft 12 via a non-synchronous belt 40. The phasing device 46 also comprises an output shaft 42 coupled to the camshaft 44; a planetary gear train 48 co-axially aligned around and coupled with the input shaft 36 and the output shaft 42; and an motor 50 coupled to the planetary gear train 48 by a carrier 56. A controller operatively connects to the engine control unit ECU, wherein the controller is configured to receive engine operating signals generated by the engine control unit ECU and to receive signals from position sensors 51 coupled to the input shaft 36 and to the output shaft 42. In response to the signals, the controller generates and sends a torque command signal to the motor 50 to command the motor 50 to control the planetary gear train 48 through the carrier 56 to adjust the phase shift angle between the camshaft and the crankshaft 12.

    • Disclosed herein are a variety of different electrical system topologies intended to mitigate the impact of large intermittent loads on a 12 volt vehicle power distribution system. In some embodiments the intermittent load is disconnected from the remainder of the system and the voltage supplied to this load is allowed to fluctuate. In other embodiments, the voltage to critical loads is regulated independently of the voltage supplied to the remainder of the system. The different topologies described can be grouped into three categories, each corresponding to a different solution technique. One approach is to regulate the voltage to the critical loads. A second approach is to isolate the intermittent load that causes the drop in system voltage. The third approach is to use a different type of alternator that has a faster response than the conventional Lundell wound field machine.
    • 这里公开了各种不同的电气系统拓扑,旨在减轻大型间歇负载对12伏车辆配电系统的影响。 在一些实施例中,断续负载与系统的其余部分断开,并且允许提供给该负载的电压波动。 在其他实施例中,关键负载的电压被独立于提供给系统其余部分的电压进行调节。 所描述的不同拓扑可以分为三类,每种类别对应于不同的解决方案技术。 一种方法是调节关键负载的电压。 第二种方法是隔离导致系统电压下降的间歇负载。 第三种方法是使用与常规Lundell伤口场机相比具有更快响应的不同类型的交流发电机。
