CHASS for a cleaner air

Emission of nitrogen oxides (NOx) is an important contributor to air pollution world-wide. Important sources of emission of NOx are power plants and combustion engines, where road transportation is an important representative. To reduce NOx emissions from vehicles, catalytic exhaust systems have been developed over the past decades. Diesel engines still represent the main point of reference for heavy transportation. This means that goals in air quality improvement and greenhouse gas emissions reduction cannot be attained without an improvement in diesel engine technology. 

The focus is on freight transport, one of the main polluting sectors, but also an important driving force of EU economy. Pollutant emission from diesel heavy-duty vehicles are not yet complying with current required standards, with important consequences on citizen’s health and social costs.
