Transportation and its systems are one of the most used and important mobility systems worldwide, assuring the development of economy and society. For this reason it is important to have non polluting characteristics, especially in the case of being equipped with internal combustion engines (most diesel ones). In this case, it is extremely important to determine the chemical pollution produced by the large diesel engines and limit, by all means, the impact of the exhausted flue gas emissions on human health and environment. The Western part of Romania has the most developed rail network of the country concerning the diesel traction, and this article is focusing on on line NOx concentration, generated by such diesel locomotives, used in the real regional railway transport. Representative measurements data set of NOx from a diesel engine will be presented. Finally, the authors demonstrate that the SCR (selective catalytic reduction) after-treatment is a present necessity to reduce NOx concentration and a best available technique to modernise the national railway fleet in Romania..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
