Automotive supplier Continental will introduce solutions at the 36th International Vienna Motor Symposium which will help diesel engines meet nitrogen-oxide (NOx) legislative limits in the future.
This comes in response to stricter NOx limits of the Euro 6 standard, the stricter super ultra-low emission vehicle (SULEV) limits for California, and the real driving emissions (RDE) test conditions.
Continental's solutions include a compact catalytic converter that can be close-coupled with the engine . This will heat up quickly and begin converting untreated emissions earlier.
The company will also introduce a new selective catalytic reduction (SCR) procedure that is claimed to improve injection of the reducing agent in the smallest available space.
Continental has developed the SCR system to inject the urea solution in the direction opposite to the exhaust flow, by allowing efficient catalytic reduction of NOx in close-coupled design.
The solution is sprayed on a structure with a hydrolytic coating on the back of the catalytic converter.
Continental Powertrain Division head José Avila said: "Future emissions systems must make real progress in terms of NOx emissions. This requires a complete understanding of the systems as well as individual components that are compatible with each other - from fuel injection to the final stage of exhaust aftertreatment.
"With the incorporation of Emitec into the Continental Fuel & Exhaust Management business unit, we now have a range of technologies that is extremely beneficial, particularly when it comes to customizing exhaust aftertreatment for different types of vehicles."
