As of\u00a0September 2017\u00a0<\/strong>all newly type-approved vehicles must comply with the regulations\u00a0Euro 6C<\/strong>regulations from September 2018<\/strong> will be compulsory for all newly registered vehicles.<\/p>\n

The regulation does not refer to diesel engines, which were already regulated by previous regulations (Euro 6A and Euro 6B), but only to petrol engines, which will have to reduce particulate emissions significantly.<\/p>\n

In order to achieve this restrictive reduction, it will therefore be necessary to adopt a particle filter similar to the one used on Diesel, the GPF<\/strong> precisely.<\/p>\n

\"\"<\/p>\n

The problem of particulate matter in petrol engines with direct injection was first highlighted in 2013 by the independent European Association : Transport & Environment<\/strong>Their research showed that, although technically more efficient than indirect injection engines, such engines release up to 1,000 times more particulate matter into the air than indirect injection engines and 10 times more than diesel engines due to the high operating temperatures and pressures.<\/p>\n

Since then, the first adopters of this system have been the Mercedes engineers, who made the filter in question available as early as 2016.<\/p>\n

In GPF filters, the exhaust gas flow is directed into a particulate filter system with a honeycomb structure, with alternating intake and exhaust ducts that close. In this way, the exhaust gas is forced to flow through a porous filter wall, which results in the separation of the soot. In the case of Mercedes, a backpressure-optimised particulate filter with high filtering efficiency is used, which at the same time is maintenance-free and self-adjusting<\/strong>. But in contrast to diesels where a ceramic particle filter made of silicon carbide (SiC) is used, 'cordierite', a particularly heat-resistant mineral, has been chosen for petrol engines.<\/p>\n

Gradually, therefore, the GPF filter will be applied to the new vehicle fleet, but as with any new equipment, only time will tell what the implications will be, especially with regard to wear and maintenance.<\/p>\n

See you next time.<\/p>\n
