During the past years great efforts were taken to investigate particle emissions from diesel engines installed in on-road and off-road vehicles. Optimization of engines and after treatment devices led to a substantial reduction of emissions from these engines. However, there is not much knowledge about particle emissions of diesel engines operated on sea. A first particle emission study was performed in May 2000. Particle emissions of a turbocharged common rail two-stroke marine diesel engine (4RTflex-58T-B from Wartisla Switzerland Ltd.) were investigated at various operating conditions and two different fuels. Size distributions were measured with a SMPS (Scanning Mobility Particle Sizer) . In addition filter samples were taken for gravimetric and chemical analysis. The diameters of the particles range between 20-40 nm independent of the operation point. No pronounced accumulation mode was found but a high nucleation mode. The particle mass is dominated by volatile organic material.
