Abstract
Particulate matter (PM) emissions from diesel engines cause environmental damage (global warming, acid rain and atmospheric pollution) and damage to human health (cardiopulmonary and respiratory diseases). Mass emissions of PM are determined by the collection, dilution and storage of these particles by constant volume sampling (CVS) in accordance with the current legislation (NBR 14489). In this sense, the main objective of this work is to present the development and characterization of a CVS dilution tunnel for the collection of particles in diesel engines. The developed tunnel was evaluated from PM sampling tests emitted by the discharge of the diesel engine from an eight-cycle test bench with different loads. The collection filters were dried, packed and conditioned in a suitable environment, later weighed in a micro equilibrium analytical model (0.001 mg resolution). The results of the weighing indicated close values in the same load, showing robustness and repeatability of the system and visible difference of color and mass for different loads, showing reliability in the proposed system.
