"The gravimetric measurement of particulate matter emissions typically requires either a full-flow dilution tunnel with a Constant Volume Sampler, or a partial flow dilution tunnel with rather sophisticated controls. In many Czech laboratories, such setup is not available due to space, power and cost reasons. As an alternative, a low-cost sampler utilizing the laboratory main exhaust duct as an improvised full-flow dilution tunnel was considered, from which a sample was drawn through a single 47 mm filter, with the flow controlled by a low-cost rotameter. While such measurement might not be suitable for modern engines achieving emission levels of units mg/kWh, with much of this mass being volatile, a reasonable correlation has been observed for older engines emitting on the order of 0,1 g/kWh." .
