摘要： This specification teaches a basic method of obtaining on a continuous basis an instantaneous indication of the air to fuel ratio of an air/fuel mixture being fed to a combustion process. The process may take place in an internal combustion engine or, for example, in a power plant. Modifications of the method are taught to obtain such information as the hydrogen to carbon ratio of the fuel being burned in the combustion process, the oxygen equivalence of the air/fuel mixture being burned, the air mass flow through the combustion process, the fuel mass flow through the combustion process, instantaneous fuel economy of a vehicle in which a combustion process is being carried out to propel the vehicle, and the oxygen concentration in the exhaust gases from the combustion process.

摘要： A method is disclosed of making an on-line gas analysis of a multicomponent gas emission flow by (a) continuously sequestering a sample flow from the gas emission flow, which sample flow has been filtered to substantially eliminate solid or liquid particles, diluted to lower its dew point to below room temperature, and changed in either temperature and/or pressure to be substantially the same in temperature and pressure as that of gases used to create reference transmission frequency spectral data deployed in step (d); (b) continuously irradiating the sample flow with an electromagnetic radiation beam while modulating the amplitude of infrared frequencies in the audio frequency range of the beam, either prior to or immediately subsequent to irradiation of the sample flow, to produce electromagnetic signals having discernible amplitude variations resulting from spectral interference patterns; (c) detecting and collecting the signals at a sufficiently high rate to substantially completely distinguish between adjacent spectral pattern amplitude peaks without mutual spectral interference and to permit analysis of the signals in real time; and (d) analyzing the signals in real time by (i) mathematically manipulating the signals in accordance with Beer's Law to create reformed background-corrected data, and (ii) applying reference transmission frequency spectral data to the reformed data for each suspected gaseous component to give a linear quantitative measure of the presence of each and every suspected gas component in the gas emission flow.

摘要： A method is disclosed for measuring the air to fuel ratio of an air/fuel mixture being supplied to a combustion process. This method has the following steps. An oxygen sensor station is established at which the sensor senses the difference in oxygen partial pressure from a first reference side thereof to a second oxygen measurement side thereof. The oxygen sensor is maintained at a predetermined temperature and at a pressure below atmospheric pressure. The oxygen sensor is calibrated so that the measurement thereby of an EMF between the first reference side thereof and the second oxygen measurement side thereof is indicative of the oxygen partial pressure in a gas stream passing by the oxygen measurement side thereof. A sample gas stream is drawn into the pressure across the second oxygen measurement side of the oxygen sensor. This pressure is one which allows samples to be drawn at a constant flow rate independent of that pressure. A fixed amount of oxygen is added to the sample gas stream. The oxygen in the sample gas stream is reacted with oxidizable species contained in the sample gas stream prior to passing the sample gas stream across the second oxygen measurement side of the oxygen sensor. The pressure of the gas sample is measured. The air to fuel ratio of the air/fuel mixture is determined from the measured EMF of the oxygen sensor, the total pressure of the sample gas stream and the known oxygen addition rate. Suitable oxygen sensors may be formed zirconia or titania.

摘要： A method and associated apparatus for on-line gas analysis of a multicomponent gas emission flow, comprising: continuously withdrawing and regulating the pressure of a first sample flow from the emission flow, continuously withdrawing a second sample flow from the first sample flow, the second flow sample being diluted with mass controlled amounts of diluent (N.sub.2 or air) to lower the dew point of the gas sample to below room temperature; controlling the absolute pressure of the diluted sample to the range of 920-950 mbar; frequently periodically analyzing the diluted sample flow, controlled as to pressure, by fourier-transform infrared spectrometric techniques to render a concentration measurement for each desired gas species; and correcting each concentration measurement for dilution to derive an undiluted concentration measurement representative of the actual exhaust gas, said correction being accomplished by measuring the actual air/fuel ratio of the gas emission flow to provide a theoretical carbon concentration in the undiluted exhaust gas and thereafter ratioing the theoretical total carbon concentration to the measured carbon concentration in the sample to provide the needed correction factor.

摘要： Apparatus and method are provided for testing of exhaust gas emissions from an internal combustion engine, and determining the engine's operating condition. An inferred value for the ratio of hydrogen to carbon in the exhaust, based on measured values for the H.sub.2 O, CO.sub.2 and CO components of the exhaust gas, is used to determine whether the engine and associated exhaust componentry have reached normal operating conditions. The emissions testing apparatus and method are suitable for remote testing of exhaust gas emissions from an internal combustion engine of an on-road motor vehicle. A light source emits preferably near to mid-infrared light to impinge upon the exhaust gas emissions. The emitted light includes wavelengths absorbed by exhaust species to be measured, including at least H.sub.2 O, CO.sub.2 and CO. Following impingement on the exhaust gas emissions, the light is received by a sensor which generates an output signal corresponding to the amount of light received at each of such wavelengths. A signal processor determines a value corresponding to the amount or relative amount of each measured specie in the exhaust gas, based at least in part on the corresponding output signals from the sensor. The processor also determines the engine's operating condition based at least in part on the output signals corresponding to H.sub.2 O, CO.sub.2 and CO. In particular, the processor determines whether the engine is in normal operating condition, rather than in cold-start or warm-up condition.

摘要： A method of time-aligning sequential gas concentrations, generated by a non-plug flow real time emissions analyzer, with corresponding plug flow inputs from an emissions source includes selecting a sequence of known plug flow test gas pulses representative of the emissions source, feeding the known plug flow test gas pulses into the analyzer, saving a sequence of blurred test pulses generated by the analyzer, determining a mathematical relationship between the known plug flow test gas pulses and the blurred test pulses, configuring a filter such that the filter corresponds to the mathematical relationship, inputting a subset of the blurred test pulses into the filter, recording a sequence of deconvoluted test pulses generated by the filter, comparing the deconvoluted test pulses with a subset of the known plug flow test gas pulses to generate difference errors, adjusting the filter to minimize the plurality of difference errors, repeating the first inputting step, the first recording step, the comparing step, and the adjusting step to reduce the difference errors, feeding the plug flow inputs into the analyzer, recording the sequential gas concentrations generated by the analyzer, and deconvoluting the sequential gas concentrations.
