But Wait There is More - Tightening Emission Regulations

Emission standards are tightening around the world. These regulations are becoming more stringent with additional laws phasing in over time, almost like the all too catchy phrase heard in most infomercials, "but wait there is more."

In Europe, one of the regulations is Euro 6, which states that the nitrogen oxide emissions in light-duty diesel vehicles must be less than 80 mg/km starting in 2014.

These innovative technologies can meet the Euro 6 legislation but also offer a solution for the "but wait there is more" legislation such as 6c.

True to form, there are more additions and requirements to build on Euro 6 - one element being the Euro 6c legislation. This regulation has been put in place and will include vehicle emission tests based on a real-life driving experience.

Vehicles will need to meet the Real Driving Emission (RDE) requirement and will be tested using the Portable Emissions Measurement System (PEMS). In addition, the World Light Duty Transient Cycle (WLTC) test will be introduced. All these acronyms basically represent more stringent regulations and additional challenges for the after-treatment systems.

The Euro 6c will be implemented in 2017, but BASF has already anticipated this change and created a new emissions system to solve the problem.

BASF is introducing the LNT+CS4F™, a system that combines the features of the Lean NOx Trap (LNT) and a multifunctional catalyzed soot filter (CS4F). It eliminates one catalytic component from the existing solution resulting in lower system weight, space and complexity.

Under such demanding conditions of Euro 6c, this LNT catalyst needed to have fast NOx adsorption kinetics and high NOx adsorption capacity at higher temperatures when compared with current LNT technologies. The filter then cleans up the rest. It removes particulate matter plus provides:

  • Carbon monoxide (CO) clean-up
  • Hydrogen sulfide (H2S) suppression
  • Ammonia (NH3) suppression
  • Additional NOx conversion
