Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

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 starting point of engine braking is marked by a vertical green line, and the end point is marked by a vertical red line.

Study shows renewable diesel from crude tall oil is a high quality drop-in fuel for off-road engines

Green Car Congress

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. No engine or parameter modifications were made.

Study finds Neste renewable diesel significantly reduces PM emissions in off-road mobile machinery; lower number and mass

Green Car Congress

A study led by researchers at Tampere University of Technology in Finland found that the use of neat Neste MY Renewable Diesel in working machines—a Wille 355B compact utility machine and Wille 855C multi-purpose wheel-loader—efficiently reduces particulate matter emissions compared to EN590 diesel with 7% biodiesel.

Neste: use of our renewable fuels reduced global climate emissions by 8.3 million tons in 2017

Green Car Congress

The positive result was made possible by Neste’s increased production volumes at its renewables-producing refineries in Finland, the Netherlands, and Singapore. The older and less developed the engines, the clearer emission-cutting benefits Neste MY Renewable Diesel can offer. million tons from 2016.
