    • In one embodiment of the present invention, a system is disclosed for monitoring the backpressure produced by a particulate filter of an internal combustion engine. When the backpressure of the engine exceeds a predetermined threshold, indicating that the particulate filter should be serviced soon, an input to the electronic control module (ECM) indicating the intake manifold boost pressure is shunted to ground, thereby giving the ECM a false indication that no boost is being applied to the intake manifold. This will cause the ECM, according to its normal engine management software, to derate the engine performance to a “no air torque setting”, thereby limiting the amount of torque that the vehicle operator can extract from the engine. This decreased performance of the engine provides a very high incentive to the vehicle operator to bring the vehicle in for servicing, at which point the particulate filter can be serviced. Upon servicing of the particulate filter, the backpressure threshold condition is no longer met, the input line to the ECM from the boost pressure sensor is no longer shunted to ground, and engine operation is returned to normal. Other embodiments of the present invention contemplate the use of engine performance derating in order to provide the vehicle operator with an incentive to have any sensed engine or vehicle condition serviced.
    • 在本发明的一个实施例中,公开了一种用于监测由内燃机的微粒过滤器产生的背压的系统。 当发动机的背压超过预定阈值时,指示微粒过滤器应该很快被维护,指示进气歧管增压压力的电子控制模块(ECM)的输入被分流到地面,从而给予ECM错误指示, 没有对进气歧管施加增压。 这将使ECM根据其正常的发动机管理软件将发动机性能降至“无空气扭矩设定”,从而限制车辆操作者可以从发动机中提取的扭矩量。 发动机性能下降给车辆操作员提供了非常高的动力,使车辆进行维修,此时可以对颗粒过滤器进行维修。 在对颗粒过滤器进行维修时,不再满足背压阈值条件,来自升压压力传感器的ECM的输入线不再分流到地面,并且发动机运转恢复正常。 本发明的其他实施例考虑使用发动机性能降额,以便为车辆操作者提供服务任何检测到的发动机或车辆状态的动机。

    • An electrical coupler for coupling a load to a plurality of power sources including positive and negative load connection points. These connection points include first and second positive power connection points and first and second negative power connection points. A first electrical path is provided between the positive load connection point and the first positive power connection point. A second electrical path is provided between the positive load connection point and the second positive power connection point. The second electrical path is the same length as the first electrical path. A third electrical path is provided between the negative load connection point and the first negative power connection point. A fourth electrical path is provided between the negative load connection point and the second negative power connection point. The fourth electrical path is the same length as the third electrical path.
