Self Study Program 558 – Close-coupled Petrol Particulate Filter

Self Study Program 558 – Close-coupled Petrol Particulate Filter PDF free online

Particulate filters have been standard in vehicles with diesel engines for a while now. This applies to passenger vehicles, goods vehicles, buses and even tractors.

The first diesel engines equipped with particulate filters were used as early as the 1970s in mining and in factories. The first car with a particulate filter was produced in 1985 exclusively for the American market.

Volkswagen produced its first diesel vehicle with particulate filter in 2004 for the European market.

On 1 September 2017, the emission limits for the particle number were lowered for type approvals of vehicles with direct injection petrol engines in the EU. A transition period of one year shall apply to new vehicles that already have a type approval.

Volkswagen is, however, already pointing the way and is fitting a 1.4-l 110-kW TSI petrol engine with particulate filter in the Tiguan. The model with this engine is spearheading new developments in the area of petrol engines.
