APPARATUS AND METHOD FOR MEASURING SIZE AND DENSITY OF PARTICLES IN DISCHARGE PIPEPURPOSE: To accurately and rapidly measure the size and mass of particles contained in exhaust gas.CARL THOMAS Lトーマスエルカール
A bag body is deformable and has an internal space for storing at least a connection side of the gas connection part to the pipe, and the whole of the pipe therein. The pipe encloses the gas ejected from the gas ejection holes into the internal space therein. A gas exhaust port is ...
NOx concentrations at engine out and tailpipe, engine speed, coolant temperature and the temperature of the exhaust gas at the SCR unit's inlet and outlet, when available, were logged at the OBD port. Light-duty testing SCR light-off is a critical parameter when assessing a potential ...
PROBLEM TO BE SOLVED: To provide a measuring device equipped with a soot sensor arranged in a gas pipe for soot particle-entraining gas, and its using method, and a sensor and a method for determining the soot concentration in the soot particle- entraining fluidized gas, capable of detecting...
CO2 gas can be derived from different sources: from vapourised liq- uid CO2 stored in a refrigerated and pressurised con- tainer near the greenhouse site, or from burning natural gas and releasing the (scrubbed) exhaust gases inside the greenhouse. Uniform distribution is often accomplished by ...
the pipe 6.2 to the fresh-air supply system 2, corresponds approximately to the outside air pressure PA. The lambda probe 7 therefore always determines the oxygen content in the exhaust under constant pressure conditions. The amount of exhaust flowing via the pipe 5 into the measuring chamber ...
A device for recalibrating an exhaust gas mass flow sensor includes a first sensor, a second sensor, and a control unit. The first sensor comprises a heati... P Gmbh 被引量: 0发表: 2016年 Measuring device for gas/liquid flow - ScienceDirect For the design and scale-p of gas/liquid ...
the main valving member 40 into the closed position. A vacuum is applied to the vacuum cavity 95 through a vacuum port 91 of the main actuator housing 86 for urging the main spindle 41 upwardly and in turn the main valving member 40 into the open position. An exhaust port 92 through a...
without the potential of data bias. As seen in FIG. 2 the probe has a nose portion44defining an inlet passage46projecting into the exhaust pipe40. Thus, a proportionate sample of a particle-laden exhaust stream, as is indicated by the reference number48, is directed into the dilution ...
It is the main object of the invention to disclose a method which is suitable for measuring a flow speed or a flow rate of air or another gaseous fluid containing a large amount of dust and flowing inside a large air-supply duct or a combustion exhaust-gas pipe having a large inner diam...
