Diesel locomotive engines are a major contributor to air pollution in cities and ports around the world. The Enspirit ('Eliminating NOx, SOx & Particulate in Rail Transportation') project is developing an innovative emissions abatement system to reduce pollution and to meet stringent new particle matter regulations.

By 2030, the EPA (Environment Protection Agency) estimate that trains will be responsible for around 30% of all particulate pollution in the air from the transportation sector. The danger lies in the fact that diesel locomotives produce nitrogen oxides, which cause a wide variety of health and environmental impacts.

The Enspirit project aims to reduce this this level of pollution by developing an innovative diesel emissions abatement system. This will also enable locomotive operators to meet new emissions regulations covering both new and older remanufactured locomotives, such as the 2008 Clean Air Non-road Diesel Rule which requires the allowable levels of sulphur in fuel used in locomotives to be decreased by 99%.


The research leading to these results has received funding from the European Union's Seventh Framework Programme managed byREA Research Executive Agency (FP7/2007-2013) under grant agreement no FP7-SME-2013-2-605019.
