Summary
Upcoming Euro 6 regulation will enforce beside the well-known limits for hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) also tighter control of particulate matter emissions from gasoline-engine powered vehicles. The European Commission has decided to implement new standards for the maximum number of particulates in two phases. Phase 1 will start with an initial limit of 6x1012/km in 2014 followed by phase 2 (Euro 6c) with a more stringent standard of 6x1011/km in 2017. In addition, Real-Driving Emissions (RDE) need to be considered from 2017 onwards. Three general approaches are currently followed to meet these challenging particulate legislation limits: 1. Changes to engine hardware and engine control strategies 2. Addition of a non-catalyzed filter to the exhaust system 3. Use of a catalyzed Gasoline Particulate Filter (c-GPF)
Lectures from the International Vienna Motor Symposium can be ordered from the Austrian Society of Automotive Engineers (ÖVK). Lectures can only be purchased in the form of the complete conference documents, individual lectures are not available.
When placing an order, please note the year/name of the event (e.g. "45th International Vienna Motor Symposium 2024") for the further ordering process.
Members of the Austrian Society of Automotive Engineers have access to all lectures of the International Vienna Motor Symposia.
