Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

A team from the University of Vaasa (Finland) and UPM-Kymmene Corporation has examined how the blends of fossil and renewable diesel produced from crude tall oil (CTO) affect the performance and exhaust emissions of the modern common-rail off-road diesel engine. Neat HB was also studied. —Niemi et al. independent of fuel.

A key factor is International Maritime Organization Tier III emissions standards, which are slated to take effect in 2015-2016. For existing ships, after-exhaust treatment is proving more popular, but for newbuilds, operators are taking advantage of LNG’s properties. —Tom Campbell, LNG-fuel analyst at Zeus.
