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 exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

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. UPM BioVerno renewable diesel is produced from wood-based tall oil.

Survey finds LNG-fueled ship orders up 26% in six months

Green Car Congress

High oil prices, impending emissions regulations and technical advancements are propelling the market faster than we expected. A key factor is International Maritime Organization Tier III emissions standards, which are slated to take effect in 2015-2016. Accelerating growth is what you would expect under these circumstances.

Neste files patent on gasoline fuels with high bioenergy content

Green Car Congress

from VTT Technical Research Centre in Finland and Neste showed that a combination of ethanol or isobutanol with bio-hydrocarbon components offers an option to reach high gasoline bioenergy content for E10-compatible cars. Typically, commercial grade E85 fulfills the Swedish standard SS 155480, with the RON around 104 and the MON around 88.

Study finds that optimizing engine parameters for renewable diesel can reduce PM and NOx both by more than 25%

Green Car Congress

A team of researchers in Finland reports that by adjusting engine parameters for the use of hydrogenated vegetable oil (HVO) renewable diesel fuel across a range of loads (50%, 75%, and 100%), particulate matter and NO x emissions can both be reduced by more than 25% relative to the values from using HVO with standard engine conditions.
