Measurement of vehicle emissions using static and dynamic tests
Vehicle emissions represent one of the main sources of particulate matter and polluting gases. Traditionally, these emissions have been assessed using static tests. While they allow for standardized measurement conditions, they do not realistically reflect the behavior of vehicles in circulation. On the other hand, dynamic tests offer a more accurate approximation of the real-world context of on-road emissions, considering factors such as acceleration, deceleration, gradients, and different speeds. Given this reality, it is necessary to compare both static and dynamic methodologies to understand their advantages, limitations, and applicability, and thus contribute to a better interpretation of the data obtained and their use in control strategies.
The objective of the course is to evaluate and compare current vehicle emissions measurement methodologies using static and dynamic tests, so that participants understand the differences between the two approaches and their relevance in the real-life context of vehicle traffic. Experience with dynamic emissions in Colombia will be shared so that, after completing this analysis, participants will be able to apply the acquired knowledge to propose effective strategies aimed at improving air quality.

Session 1
Theoretical: Technical comparison of static vs. dynamic testing, national and international methodologies, applicability of each approach in different contexts.
Session 2
Practical workshop: Static measurements, dynamic measurements using the WLTP cycle on a dynamometer, and real-time measurement recording of particle mass and number along with unregulated gases, interpretation of results obtained from both tests, and group discussion of the findings.
