Clean air is a priority for all of us, and despite significant progress made over the past years, air pollution from various sources lead to exceedances of European air quality standards, particularly in highly populated areas. This is why authorities around the world work continuously to further improve source emission legislation to protect citizens in their daily lives: while travelling to work or school while working, studying, playing or taking part in any activity close to a busy road.
Emission control technologies to reduce and control emissions from combustion engines on all types of road transport or mobile machinery have been used in the EU since the 1990s and evolved ever since. Catalyst- and filter-based controls are available to reduce the level of pollutants to near zero under all driving and operating conditions, regardless of the fuel used and the type of vehicle or machine. Vehicle technology will continue to evolve and meet society’s needs in a sustainable way. State-of-the-art emission control systems will enable current and future liquid and gas-fuelled vehicles to contribute to further improvements in air quality.
Using these advanced state-of-the-art catalysts, adsorbers and filters in combination with modern engine design and clean fuel enable undesirable engine emissions to be eliminated while also reducing greenhouse gas emissions. These advanced emission control and engine technologies can also be combined with electric vehicle propulsion systems enabling a range of choices for clean mobility for the future.
The development of renewable liquid or gaseous fuels directly from waste and sustainable electricity with further increased combustion efficiency will provide an exciting route to increased sustainability of internal combustion engines. This will result in a positive contribution to reducing global warming.
As electricity sources become more sustainable, this will allow migration of some mobility requirements to electrified vehicles while other requirements, including the need for convenience and accessibility, will continue to favour the cost-effective driving distance and power available from liquid fuels.
Finally, the circular economy has always been a priority in the emissions control industry, as the precious metals used in catalysts can be recycled. Recycling rates are increasing, further contributing to the affordability of future vehicles.
