SIDI Particles: Legislation, current levels, and control

John  Kasab, Ricardo

Particulates from spark-ignited, direct injection (SIDI) engines will start to be regulated in Europe starting with the 2011 Euro 5+ limits. This paper discusses SIDI particle composition, forthcoming regulatory limits, and measurement techniques. Data from engine tests will be presented, both with and without particulate filters fitted. Other mitigation strategies will be discussed as well.
