Eberspaecher Exhaust Technology has announced it will begin mass production of exhaust systems featuring gasoline particulate filters (GPF) in May. Using the special filters means the soot particle content in the exhaust gas is well below the legal limit. As a result, the systems conform to the upcoming level of the Euro 6 emissions standard, according to Eberspaecher. The GPF will be manufactured for a number of leading German and other European automotive manufacturers. The new particulate filters will be available for all gasoline vehicles in all classes in the future.
A new level of the Euro 6 emissions standard will come into force for all new type-certified passenger cars within the European Union in September 2017. Provisions of the updated standard include a reduction in particulate limits for gasoline vehicles with direct fuel injection engines. Almost one in two gasoline vehicles is fitted with this type of engine, because direct fuel injection saves fuel and as a result minimizes carbon dioxide emissions. However, this combustion method results in increased emissions of soot particles. The new gasoline particulate filters counteract that effect, filtering the soot particles out of the exhaust gas flow, Eberspaecher says. The filters also minimize the vehicle’s exhaust noise, according to the company.
“As a pioneer in exhaust gas technology, our innovation and technology is helping to create environmentally sustainable mobility for tomorrow’s world. Our gasoline particulate filters will substantially reduce exhaust emissions, and so improve air quality,” said Dr. Thomas Waldhier, chief executive officer of Eberspaecher Exhaust Technology.
Innovative filter technology for better air quality
The Esslingen-based specialists developed the exhaust system based on the tried and proven technology of the diesel particulate filter. It employs the highly porous and extremely heat-resistant cordierite-ceramic. The soot particles are automatically deposited on the porous surface, which greatly reduces emissions. Owing to the higher exhaust gas temperatures, the soot particles on the filter are continually burned off by the hot exhaust gas from the combustion chamber. So active regeneration (cleaning) as in the case of diesel vehicles is not required in normal running.
