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.

First online measurement of gaseous sulfuric acid in diesel exhaust helps clarify role in formation of nucleation particles

Green Car Congress

Researchers in Germany and Finland report the first online measurement of gaseous sulfuric acid (GSA) in the exhaust gas of a modern heavy-duty diesel engine in an effort to quantify the role of low-vapor-pressure gases in the formation of nucleation particles (NUP). of hydrocarbons) significantly. —Arnold et al.

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.

GoodFuels Marine and Boskalis successfully test UPM’s sustainable wood-based biofuel for marine fleet

Green Car Congress

UPM BioVerno is produced from wood-based tall oil. Crude tall oil is gained as a result of the separation process of fibrous material from wood; it is a residue of pulp manufacturing.

Study: Engine optimisation key for renewable diesel gains

Green Cars News

It is well known that renewable diesel, such as hydro-treated vegetable oil (pictured), is a promising alternative to traditional diesel fuel in engines offering substantial reductions in exhaust emissions. However, to really maximise its potential, it appears that certain adjustments must be made to an engine.
