GEO2 Technologies Inc., a leading developer of multifunctional filters for next-generation clean diesel solutions, announced the introduction of a new silicon carbide (SiC) substrate for diesel particulate filtering. GEO2’s patented microstructure is poised to drive the next wave of high-temperature filter innovation, effectively removing 99 percent of pollutants from diesel exhaust while achieving better fuel economy, emissions control and enhanced engine performance.

An industry first, GEO2’s SiC substrate achieves high porosity and high strength simultaneously while delivering lower back pressure and high trapping efficiency. Also, unlike other SiC products, GEO2 filters are based on a cross-linked microstructure (CLM) that effectively reduces the size, weight and cost of emissions control systems.

“Today, the need for clean transportation technology is critical given a growing number of health and environmental issues associated with fossil fuels,” said Bilal Zuberi, vice president and co-founder, GEO2 Technologies. “By innovating solutions such as the new cross-linked microstructure SiC diesel particulate filter, we can offer auto manufacturers an affordable means of controlling toxic particulate and CO2 emissions while preserving all the benefits of diesel fuel, including better gas mileage and improved vehicle performance.”

Historically, diesel was seen as dirty and responsible for contributing wildly to global warming. However, innovations in the field have led to the emergence of clean diesel as one of the most viable solutions on the market for addressing today’s emissions control challenges. Not only does clean diesel eliminate harmful pollutants from exhaust, but it also achieves 25 to 30 percent better fuel economy than gasoline.

“The industry needed a new material that could clean up emissions without the compromises associated with traditional filters, including higher cost and weight and reduced efficiency,” continued Zuberi. “That’s exactly what we’ve done with this new SiC filter - created a breakthrough material that can be integrated easily into existing vehicle platforms to improve performance.”
