Particulate emissions reduction

Politics, science and society claim high effort against the on-going climate change by emitted anthropogenic climate gases. Especially the transport sector is often the focus of attention and has to manage enormous challenges today. The worldwide becoming stricter emission laws to regulate the emissions of passenger cars and commercial vehicles accompanied with the requirement to reduce carbon dioxide represent a conflict in the development of engines.

Gasoline engines with direct fuel injection in combination with turbocharging as high-efficient Downsizing-Engines have a high potential for increasing the efficiency and to reduce CO2 emissions.

At the Institute for Powertrains and Automotive Technology (IFA) of Vienna University of Technology studies to minimize the particle emissions, which are characteristic for direct-injection gasoline engines, is a main focus with extensive experience.

This is especially with regard to the 2014 coming into force EURO 6 emission standard, which limit the particle mass to 4.5 mg/km and the number of particles to 6*1012 1/km, important. Limit estimations of the potential benefits of DISI engines to reduce CO2 emissions show that this effort is justified to force this concept as a high efficient engine. The following figure shows the number of particles in the raw exhaust depending on engine speed and brake mean effective pressure of a typical direct-injection turbocharged gasoline engine in the relevant area for certification.
