    摘要: Functionality of the exhaust gas oxygen sensor is determined by continually monitoring the exhaust gas oxygen sensor voltage to determine both a peak rich voltage and peak lean voltage. Based on the information after some predetermined time period, a system determines whether rich air/fuel ratio excursions are required and lean air/fuel ratio excursions are required. If a rich air/fuel excursion is required, then there is a command to decrease the air/fuel ratio to make it rich until the peak rich voltage is greater than a predetermined threshold voltage. Analogously, if a lean excursion is required, then there is a command to have a lean air/fuel ratio excursion done until the peak lean voltage is less than a predetermined threshold. If a time out happened before the peak rich voltage was greater than the rich threshold or the peak lean voltage was less than the lean threshold, then there is a determination that there is a malfunction detected on the sensor/circuit.

    摘要: Air/fuel ratio in an internal combustion engine is controlled so as to test the operation of an exhaust gas oxygen sensor. The engine is divided into two banks, each bank including an intake bank of cylinders, an exhaust path, and an exhaust gas oxygen sensor in the exhaust path. Air/fuel ratio control signals are used in connection with each of the two banks, the control signals being 180.degree. out of phase with each other.

    摘要: A system for detecting a fault in an exhaust gas oxygen (EGO) sensor includes generating a first signal with a first voltage if the EGO sensor output signal is approaching an unacceptable voltage and a second voltage if the EGO sensor output signal has an unacceptable voltage. The system further includes setting a first flag if the first signal has the first voltage and a second flag, indicating an EGO sensor fault, if the first signal has the second voltage and the first flag is set.

    摘要: Method, for controlling fuel supply to an internal combustion engine utilizing a modulated air-fuel signal having a modified square-wave waveform, of monitoring operation of an oxygen sensor for sensing engine exhaust gas oxygen level. The method includes generating the modulated air-fuel signal having the modified square-wave waveform designed to produce a particular engine exhaust response for interrogating the oxygen sensor, and operating the engine based on the modulated air-fuel signal. The oxygen sensor produces an associated output signal in response to sensed exhaust gas oxygen levels. The method also includes processing the output signal of the oxygen sensor associated with the particular engine response so as to determine the operating condition of the oxygen sensor and to verify acceptable test conditions.

    摘要: An ink jet ink includes an ink vehicle, wherein the ink vehicle includes at least one wax monomer functionalized to include in the chain at least one reactive group curable upon exposure to radiation. The reactive group is preferably curable via cationic or free radical polymerization. In a preferred embodiment, the ink vehicle includes a wax monomer having a structure: wherein C represents a cationically curable group and R represents a radically curable group. The inks may be used to form an image by jetting the ink onto a transfuse member surface, increasing the viscosity of the ink upon the transfuse member surface, subsequently transferring the ink from the transfuse member surface to an image receiving substrate, and exposing the ink to radiation following the transfer to the image receiving substrate to effect reaction of the at least one reactive group.
