Definitions
- such a measurement device comprises a certain number of drawbacks that today must be solved in order to be able to make more reliable, faster and easier measurements.
- the time to perform pollutant measurements with such a cross probe is very long, which is due in particular to the fact that it is imperative to establish in advance of each measurement a detailed mapping of the output section of the exhaust flow, which is highly dependent on the engine studied, and must therefore be established again for each new engine.
- Such a cross probe also has the major disadvantage of requiring a very specific design and dimensioning engine studied, and more specifically to the output section of the exhaust flow of said engine. It is thus necessary to manufacture a new device, frame and cross probe, for each new engine tested, which is not economically viable, and which is also time consuming.
- such a device has a large footprint which makes its manipulations difficult.
- it allows a measurement of pollutants, in a reasonable time, only on a limited number of sampling points of the sampling surface, making the measurements of pollutants less reliable.
- an analysis unit coupled to the probe to perform a characteristic data acquisition of the exhaust flow taken by the probe; Controlling a displacement of the probe to impart a continuous displacement of the sampling orifice along a trajectory specific to the sampling surface, while continuing the sampling and acquisition of characteristic data of the exhaust flow taken by the probe;
- the displacement of the probe is controlled so that its trajectory corresponds to a surface scan per unit time constant.
- the data acquired by the analysis unit is correlated with the position of the sampling port of the probe.
- the method comprises a preliminary step of activating the probe to begin a sampling of gas at the sampling port towards the analysis unit.
- a measuring device for implementing the above method.
- control unit is provided to impart a displacement to the probe with a trajectory corresponding to a surface scan per unit time constant.
- the analysis unit comprises at least one filter for capturing fumes present in the exhaust stream.
- the robot 2 with its articulated arm 20 are provided to allow the probe 1 to be moved at different points at the output of the engine 3. More specifically, the robot 2 comprises means for positioning the sampling port 10 of the probe 1 at different points of a sampling surface 5 at the output of the engine.
- the sampling surface 5 is defined beforehand and corresponds to the surface area representative of the zone where the pollutants are to be measured. This sampling surface 5 has a shape that is generally dependent on the outlet section of the exhaust stream coming from the engine 3.
- the sampling surface 5 is preferably plane, in which case it is referred to as a sampling plan.
- the robot 2 is such as to position the sampling port 10 of the probe 1 at all points of the sampling surface defined at the output of the engine.
- the probe 1 also comprises a rigid envelope which surrounds the tubular body 1 1 transport.
- This rigid envelope makes it possible in particular to protect the hot gas transport tube and to stiffen the probe 1 as such.
- the probe 1 is made of steel and has a sampling orifice 10 having an opening 3 mm in diameter.
- the probe 1 may for example have an overall length of the order of 70 cm.
- the probe 1 comprises a suction system for circulating the gases taken at the sampling orifice in a set of ducts (s) to a unit of analysis provided for analyzing the gases taken. by the probe.
- the analysis unit may for example be a non-dispersive absorption analyzer for infrared radiation for CO or CO 2 analysis, and / or a flame ionization hydrocarbon analyzer, and / or a chemiluminescence analyzer for analysis. NO and NOx. According to these examples, it generally also provides a computer system for recording analyzer analysis data.
- the analyzer used in the analysis unit allows itself to record the characteristic data of the exhaust stream.
- the analyzer in the form of a filter, this filter accumulating the characteristic data of the solids contained in the flow of escapement, achieving at the same time a continuous acquisition of these characteristic data.
- one or more analyzers are arranged at the probe, for example at the outlet of the sampling probe 1 as illustrated in FIG.
- This control unit 21 is designed to impart a continuous displacement of the sampling orifice 10 of the probe 1 along a path specific to the sampling surface. This trajectory of displacement is defined specifically according to the desired measurements, as is explained later in the text.
- the sampling probe can be very quickly retracted into a retracted position, in a few seconds, for example to position it outside the exhaust stream if a risk of burns is detected, which ensures better safety.
- the continuous displacement of the probe 1 and the continuous acquisition of characteristic data of the exhaust flow taken by this probe 1 have the advantage of allowing a detailed analysis of the pollutants present at a given point of the sampling surface in a continuous manner. , that is to say without having to wait for a dead time where no analysis is possible, this dead time corresponding to the time required for the flow to reach the analyzer from the sampling port. Indeed, with the proposed measurement method, the stream to be analyzed arrives continuously at the level of the analysis unit and the data acquisitions are successive, shifted in time without dead time between each significant acquisition.
- a circle trajectory is for example formed of several concentric circles of different radii and of one or more segments connecting two adjacent circles.
- the circle trajectory shown in Figure 3 comprises four concentric circles C1, C2, C3, C4, where two adjacent circles are connected by a single segment.
- the data acquired by the analysis unit is processed to determine the nature and concentration of gas contained in the exhaust stream taken.
- This treatment can be carried out by any type of known method and at the disposal of the person skilled in the art.
