Summary

To address customer demands of individual mobility, but not to emit more CO₂ than necessary, the automobile industry introduces a growing number of highly efficient gasoline engines equipped with direct injection systems. This type of engines enables coming to the target as close as possible, the same time it generates fine and ultrafine particulates. A growing number of scientific reports show the negative impact of particulates on climate and health. To address the same, the European Union introduces with EU6 Legislation particulate number limits in addition to particulate mass limits. In addition, extended emission test methods are being investigated. They should ensure that the new emission limits are not only met during traditional emission test cycles, but under real world driving conditions as well.
