The emission legislation is a driving force of vehicle industry in terms of reducing exhaust gas emissions. To meet the tightening emission limits there is need to develop engine technology to decrease engine out emissions as well as a need to use different type of exhaust gas aftertreatment devices. Particulate emissions are one of the main concerns especially with diesel powered vehicles. At the same time with the tightening emission legislation there is a clear demand on decreasing greenhouse gas emissions of traffic. The use of renewable fuels instead of fossil fuels is one possible way to reduce traffic related CO2 emissions. At VTT's engine and vehicle laboratory there have been several projects and research programs to define the emissions of heavy duty vehicles using different aftertreatment systems and alternative fuels and the some of the main findings about the particulate emissions will be presented.
