Diesel Smoke Visible black smoke emissions from diesel engine result on account of high concentration of soot in the exhaust gas. In view of the demands of advanced, low emission diesel engines, the following areas of concern can be identified in conventional smoke opacity meter technology:.

Please Select an item from the Left dropdown Menu. Diesel Exhaust Emissions and Diesel Exhaust Smoke Meters Typical modern Diesel Smoke Meter at work Diesel Exhaust Smoke meters, also referred to as opacity meters, detect and measure the amount of light blocked in a sample of smoke emitted by diesel engines from cars, trucks, ships, buses, motorcycles, locomotives and large stacks from industrial operations.
The smoke meter readout displays the smoke density giving a measure of the efficiency of combustion. This makes the smoke meter an excellent diagnostic tool to ensure proper maintenance of diesel engines for improved fuel economy and protection of the environment.
The opacity meter consists of an optical unit mounted inside a measuring head and a separate electronic control unit. The measurement principle is based on light extinction detection. The collimated beam from the light-source SLED is absorbed and scattered by the particulate exhaust emissions. A photodiode determines the light intensity of the attenuated beam and the corresponding opacity value is transmitted to a separate remote display.
Partial flow continuous gas sampling combined with a heated and temperature controlled smoke chamber compensates for changes in pressure and test conditions to give you the most accurate readings possible.
That is why the government introduced a by-law-model for adoption by the different municipalities in SA as an easy guide. Pages deal with diesel exhaust emissions description and suggested limits while Chapter 2 deals with the actual nature of diesel exhaust emissions testing in South Africa. Why not just use the proven method of Gas Analyzing as done with Petrol engines? Diesel soot is by nature oily thus quickly clogging the filters and sample piping of a "normal" petrol exhaust gas analyser.
Those maintenance items are fairly expensive to be changed after every single test. A modern Smoke meter is a almost no-maintenance device.
Typical modern Portable Diesel Smoke Meter What is: Diesel Smoke - Particles, including aerosols, suspended in the exhaust stream of a diesel engine which absorb, reflect, or refract light.
By convention, smoke density is expressed on a per meter basis m The smoke density is a function of the number of smoke particles per unit gas volume, the size distribution of the smoke particles, and the light absorption and scattering properties of the particles. First and foremost is back up service and maintenance. Smoke Meters have to be calibrated or at least checked to maintain optimum accuracy at least once a year. User maintenance on modern units is usually down to cleaning the optics when necessary.
Are the digits clearly visible when away from the machine at least 2 metres? Can it Record the smoke values for later evaluation? Does it have Diagnostic capabilities?
Does it provide any Help when you get stuck for any reason? Does it have a Customer Database to save their results for later printing or evaluation? Does it have acceptable printing capabilities? Some print on small sized paper. Can it include your Customer names in the Print outs? Can it measure in N and K-1 simultaneously What More does it have to offer, compare to other makes and models? Is it reasonable priced for what it has to offer? For more detailed information about the nature of diesel smoke emissions Diagnostics visit our Tech Things To Know section.

Bratilar All the diesel engine design and operating variables that affect soot formation and oxidation also influence black smoke intensity. These instruments have been designed to quantify the visible black smoke emission utilizing such physical phenomena as the extinction of a light beam by scattering and absorption.

Bragar In fact, the smoke opacity measurement is the only relatively low-cost and widely available method to measure a PM-related emission parameter in the field.
