摘要： A differential capacitive pressure sensor of an embodiment of the present invention has first and second diaphragms positioned on opposing sides of a single substrate. Each diaphragm of the pressure transducer is configured to be exposed to a transient fluid, with the first and second pressure transducers being arranged with their respective deflection surfaces directed outwardly from each other. The differential capacitive pressure sensor may be configured to output representations of differential and common mode pressure of the transient fluids, where a representation of a common mode is cancelled in generating the representation of the differential pressure. The transient fluids may be the same fluid at different locations within a flow path. The diaphragms may be constructed from a ceramic material to be able to withstand exposure to corrosive or caustic fluids.

摘要： An engine pressure sensor monitoring system uses the position of a wastegate in a turbo-charged engine when known and calibrated engine operating conditions occur to provide diagnostic information for various engine pressure sensors and for the operation of the wastegate itself. Discrete measurement windows are defined for engine conditions with specific values for parameters that may include rpm, torque, injection timing and fuel consumption. Other sensor readings for intake manifold pressure, turbocharger compressor output pressure, peak cylinder pressure, and wastegate valve position during these measurement windows should match predicted values. If measured and predicted values do not match, one or more sensors may be bad and an alarm may be raised.

摘要： A system and method are provided for estimating an operating parameter of an exhaust manifold of an engine. In the system, a flow value is determined that corresponds to a flow rate of exhaust gas through an EGR conduit fluidly coupled between the exhaust manifold and the intake manifold. The EGR conduit includes an exhaust gas cooler disposed in-line with the EGR conduit and a property of the exhaust gas exiting an exhaust gas outlet of the cooler is measured. The operating parameter of the exhaust manifold is estimated as a function of at least the flow value and the property of the exhaust gas exiting the exhaust gas outlet of the cooler. Illustratively, the operating parameter of the exhaust manifold may be exhaust manifold pressure and/or temperature.

摘要： A sensor control apparatus which receives from a gas sensor (10) a sensor output signal Ip corresponding to the concentration of a specific gas component, and a pressure signal P output from a pressure sensor (20). The sensor control apparatus includes a computation section (38) which computes a specific component concentration which is corrected based on the pressure signal P so as to eliminate the influence of the pressure of the gas. The sensor control apparatus includes response adjustment sections (34) and (36) for adjusting the response rates of the sensor output signal Ip and the pressure signal P before being input to the computation section (38), the response rate exhibiting a time variation of the corresponding signal to a change in the pressure of the gas, such that the response rate of the sensor output signal Ip or the response rate of the pressure signal P, whichever is faster, approaches the slower of the two.
