    摘要: A clogging determination device includes a first antenna disposed at one of a side of a first end and a side of a second end of a filter disposed internally of a case, a second antenna disposed at the other of the side of the first end and the side of the second end of the filter, a multi-tone signal generator that has an output terminal coupled to the first antenna, outputs from the output terminal a multi-tone signal obtained by compositing a plurality of signals having different frequencies, and moves a position of an envelope of the multi-tone signal emitted to the filter from the first antenna, a detector that is coupled to the second antenna, and detects an intensity of the multi-tone signal received by the second antenna, and a determinator that determines a degree of clogging of the filter based on an intensity of the multi-tone signal.

    摘要: A device for detecting the concentration of a given component in a solution, preferably the concentration of urea in solution with water includes a means for emitting radiation, at least one means for receiving radiation, which is prearranged for determining at least one characteristic of the radiation, and a light guide, which is prearranged for optically connecting the emitting means to the receiving means, wherein the light guide has at least one surface that is to come into contact with the solution so as to determine an interface of separation between the propagation medium and the solution. Control means are configured for obtaining a value indicating the concentration of the compound in the solution as a function of the signal coming from the receiving means.

    摘要: An exhaust gas purification device for an internal combustion engine, wherein an amount of fuel supply during a forced regeneration is optimized, and a fuel efficiency is effectively improved. The device includes a filter in an exhaust passage of the internal combustion engine for collecting particulate matter in an exhaust gas, an electrostatic capacity detecting unit that detects an electrostatic capacity of the filter, and a filter regenerating unit that supplies fuel to the filter and executes a forced regeneration to burn and remove the particulate matter in the filter. The filter regenerating unit stops supplying fuel when a rate of decrease in the detected electrostatic capacity per predetermined period of time reaches or falls below a predetermined lower threshold, which indicates a drop in burning efficiency of the particulate matter, while the forced regeneration is being executed.

    摘要: A system includes a controller programmed to monitor an oxidation state of a three-way catalyst (TWC) assembly coupled to a combustion engine. The controller is programmed to receive signals representative of oxygen (O2) concentration in a fluid both upstream of an inlet and downstream of an outlet of the TWC assembly, to receive a signal representative of the measured O2 storage of the TWC assembly from at least one radio frequency (RF) probe disposed within the TWC assembly, to utilize a model to generate an estimated O2 storage of the TWC assembly based at least on the O2 concentration in the fluid both upstream and downstream of the TWC assembly, to compare the estimated O2 storage to the measured O2 storage, and to output a control action for the TWC assembly based at least on the comparison of the estimated O2 storage to the measured O2 storage.
