Proven Diesel LPV Mobile SCR Technology for Upcoming German NOx Emission Regulations

Martin Pley, Dr.Pley, Webinar, Webcast Experts, Diesel LPV Mobile SCR



The “Dieselgate Scandal” of 2015 revealed that an estimated 65-80% of diesel light passenger vehicles (LPV) sold in France, Germany, Italy, and the UK produce more than three times the Euro 5 and Euro 6 standard emission limit of 180 and 80 mg NOx/km, respectively. Software or “defeat devices” allowed manufacturers of Volkswagen, Porsche, Audi, Seat and Skoda brands to knowingly certify compliance with exhaust emission standards when in fact their vehicles failed to meet the standards under actual driving conditions.

Momentum is growing in EU, Germany in particular, with courts forcing a series of recalls including the Ministry of Environment in Germany who issued a recall of 22,000 Porsche Cayenne 3.0TDIs for repairs.  OEM’s have responded with a proposal to update software that will reduce NOx emissions by 15-25% in five million of the 15 million diesel vehicles owned in Germany. The offer was rejected by regulators with at least four major German cities proposing a diesel ban that will be devastating to owners and manufacturers of diesel vehicles.  Such a ban will require the implementation of hardware upgrades generating market demand for a low-cost, compact selective catalytic reduction (SCR) system that will reduce NOx emissions by up to 95%.

Now offering Certificates of Completion for all our Webinars.

Dr Pley SCR Technology GmbH, is a European engineering firm offering a proven innovative SCR retrofit package that uses readily available diesel exhaust fluid (DEF) to reduce NOx emissions to levels demanded by EU regulations.  The compact SCR system includes DEF storage, the metering and hydrolysis components necessary to directly inject the NOx reducing reagent (ammonia) into the diesel engine exhaust at operating temperatures consistent with on-road driving conditions.

In this webinar, Dr. Martin Pley, the managing partner of Dr. Pley will present technology details as well as test results acquired from a regiment of EU qualified on-road research demonstrations. Testing has proven that NOx emissions can be reduced to Euro 6 levels with components small enough to fit within light passenger vehicles at an affordable cost.  

Dr. Pley Diesel SCR Highlights:

  • LPV SCR retrofit package technology overview

  • Newly developed ECU capable to operate the SCR system by correction curves or with NOx sensors

  • SCR catalysts with advanced coatings on metallic substrate allow low temperature light-off of 120° C

  • Newly developed DEF Hydrolysis Reactor capable to convert up to 500g/hr DEF into NH3

  • Effective and economically competitive solution due to component costs

  • Political and regulatory outlook driving SCR technology
