Control of Soot Concentration in Oil

2017
This chapter considers the control of the oil contamination, by products of incomplete combustion (soot). Up-to-date requirements which set the necessity of development of portable monitoring devices built in the car lubrication system are considered.

Soot Concentration Interference Measurement System Caused by Multidispersion Soot Different Position

Applied Mechanics and Materials, 2014
One of the pollutant emission parameters is soot emission concentration. The light intensity scattering method is commonly used in monitoring the soot emission concentration. The distance between the sensor and the soot is different; the sensor acceptance scattering light angle range of the different position multidispersion soot is different and the ...

Measurement of the soot concentration and soot particle sizes in propane oxygen flames

Symposium (International) on Combustion, 1981
Soot concentrations and particle sizes were measured by light scattering and probe measurements in the burnt gas region of atmospheric pressure propane-oxygen flames and propane-oxygen flames to which hydrogen or ammonia were added. The results show that the soot concentrations in propane-oxygen flames, to which hydrogen is added are lower compared to ...

A light-scattering method for soot concentration measurements

Combustion and Flame, 1970
The validity of light-scatter measurements as a basis for determining soot particle size and concentration from point to point within a flame has been examined in relation to measurements on a special propane burner. The monodisperse spherical particle model relied on in the past was found to predict scatter diagrams in poorer agreement with experiment

Soot Concentration and Velocity Measurement in an Acoustic Burner

41st Aerospace Sciences Meeting and Exhibit, 2003
Laser Induced Incandescence (LII) and Particle Vaporization Velocimetry (PVV) were used to measure soot concentration and velocity in an acoustically excited combustion chamber. This acoustic burner provides a controllable environment for the study of soot formation and destruction in an unsteady flow relevant to turbulent combustion.

Real-Time Soot Concentration Measurement Technique for Engine Exhaust Streams

SAE Technical Paper Series, 1993
<div class="htmlview paragraph">A new real-time soot concentration measurement technique for engine exhaust flows is presented. The technique uses a pulsed laser to illuminate the soot particles, with subsequent detection of the incandescence from the particles.

Diffuse-light two-dimensional line-of-sight attenuation for soot concentration measurements

Applied Optics, 2008
A technique of diffuse-light two-dimensional line-of-sight attenuation (diffuse 2D-LOSA) is described and demonstrated that achieves very high levels of sensitivity in transmissivity measurements (optical thicknesses down to 0.001) while effectively mitigating interferences due to beam steering.
