Eberspaecher Exhaust Technology has announced it will be starting the mass production of exhaust systems featuring gasoline particulate filters (GPF) in May of this year. The systems conform to the upcoming level of the Euro 6 emissions standard, and will be manufactured for a number of leading German and other European automotive manufacturers. The new particulate filters will, in future, be available for all gasoline vehicles in all classes.
A new level of the Euro 6 emissions standard will come into force for all newly type-certified passenger cars within the European Union in September 2017. Its provisions 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 does result in increased emissions of soot particles. The new gasoline particulate filters counteract that effect, filtering the soot particles out of the exhaust gas flow. The filters also minimize the vehicle’s exhaust noise.
“As a pioneer in exhaust gas technology, our innovation and technology is helping to create environmentally sustainable mobility for tomorrow’s world,” commented Dr. Thomas Waldhier, COO Eberspaecher Exhaust Technology. “Our gasoline particulate filters will substantially reduce exhaust emissions, and so improve air quality.”
The company has developed the exhaust system based on the tried and proven technology within diesel particulate filters. It employs the highly porous and extremely heat-resistant cordierite-ceramic. The soot particles are automatically deposited on the porous surface, so greatly reducing 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.
