Effects of a Barium-Based Fuel Additive on Particulate Emissions from Diesel Engines

The use of barium-containing smoke suppressant diesel fuel additive was investigated. Effects on particulate reduction, other pollutant emissions, and performance were explored over a range of speed and load conditions. The particulate emissions were analysed gravimetrically and reported in terms of particle concentration and emissions index. Public health aspects of use of the additive are discussed.
