Abstract: A remote emissions sensing system is provided with NO x detection capability. First, a reading of the ambient NO x concentration is taken just prior to each vehicle passing through the system. This measurement accounts for any ambient NO x concentration that may be lingering from the exhaust of a previous vehicle. Next, the system takes a blocked reading when the vehicle is located in the path of the beam. This reading accounts for any ambient or system noise that may exist. Finally, the system takes a reading of the exhaust plume as the beam passes through the plume. A processor determines the portion of the reading due to the exhaust plume by subtracting the ambient and blocked readings from the exhaust plume reading. As a result, a more accurate exhaust concentration reading is provided. Additionally, the system may process exhaust plume readings only in a predetermined wavelength band associated with the known absorption spectrum of NO x so that data points for which there is no significant absorption of NO x may be eliminated. Thus, any noise or other interference in the non-absorptive wavelengths are minimized. Also, changes in the intensity of the radiation are compensated by subtracting a baseline intensity from each signal.

Abstract: A handheld, small but accurate and reliable device for diagnostic NO measurements using a NO sensor, where the parameters governing the taking of the sample are different from the parameters optimal for the accuracy of said NO sensor is described. By temporarily storing a portion of the exhaled air, and feeding this to the sensor at a flow rate adapted to the NO sensor, the accuracy and sensitivity of a system and/or a method involving NO sensors, can be increased.

Abstract: The present invention uses a sensor electrode (3) in a nitrogen oxide sensor (10) which includes a nitrate or nitrite of an alkali metal and an oxide of a rare-earth element. The nitrate/nitrite of the alkali metal replaces part of the lattice of the oxide of the rare-earth element, forming a solid solution. The sensor electrode (3) therefore exhibits highly practical features, especially high water-insolubility and capability of nitrogen oxide measurement in a hot and humid atmosphere containing water vapor. Thus, a highly practical nitrogen oxide sensor electrode and nitrogen oxide sensor are provided which are usable in measurement in a hot and humid atmosphere containing water vapor.

Abstract: A process for providing a real-time estimation of in-cylinder NOx production rates during a combustion process in an internal combustion engine. The process employs a model that takes into account fundamental in-cylinder variables such as temperature, pressure and oxygen content. The process can be used with calibrated or uncalibrated internal combustion engines and can be used to capture the effects in variations of engine speed, engine torque, EGR, injection timing, and engine boost levels.

Abstract: Apparatus for sensing low concentration NOx in a measurement gas especially in the atmosphere has at least one sensor element (6) made of an oxide arranged in a flow path of the measurement gas, whose resistance varies in response to changes in NOx concentration in the measurement gas. The temperature of the sensor (6) is controlled to 500 - 800 DEG C by a heater (24). Upstream of the sensor (6) in a chamber (4) is a catalyst (5) which maintains partial pressures of NO and NO2 at equilibrium, and removes combustible gas, e.g. CO.
