Diesel engines are the most powerful internal combustion engine available on today’s market with most vehicles relying on them. Heavy duty trucks, buses, off road machinery etc. are almost exclusively powered by diesel engines around the world, and diesel powered passenger cars are a very popular option too.
At present, there is no alternative available to car and vehicle manufacturers that offers the same power as a diesel engine. Governments all over the world have over the last number of years been intensifying their focus on climate change and a reduction in emissions of NOx. This means that vehicle manufacturers have had to adapt their systems to provide the same power and efficiency from a diesel engine, but with a massive reduction in the emissions of NOx. This has been achieved through the introduction of a Selective Catalytic Reduction (SCR) system. The SCR system injects a liquid-reductant agent (AdBlue) from the AdBlue tank sited in the vehicle. This then travels into a specialist catalyst where reactions occur converting the nitrous oxides (NOx) into nitrogen and water which then passes into the atmosphere through the exhaust.
In order for governments to regulate the NOx emissions, the European emissions standards were introduced a number of years ago to define the acceptable limits for exhaust emissions of new vehicles sold in the EU and EEA member states. These emission standards are defined using a series of EU directives staging the progressive introduction of the increasingly stringent standards. All countries around the world are using these standards, with some being at different stages compared to others.
