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.

In Europe, the average amount of NO x present in exhaust emissions from modern diesel passenger cars under real-world conditions is more than double the levels from modern trucks and buses, according to a new briefing paper released by the independent research organization International Council on Clean Transportation (ICCT).

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. Earlier post.). Neat HB was also studied.

Emission measurements conducted by Institute of Transport Economics in Norway, in collaboration with VTT in Finland, show that new Euro 6 cars with diesel engines are struggling with NO x emissions well in excess of regulatory type limits when in real traffic.

Neste, currently largest producer of renewable drop-in fuels (primarily diesel) with its NEXBTL platform ( earlier post ), has filed a patent ( US20150144087 ) on a gasoline composition (and the method for making it) comprising up to 20 vol% (preferably from about 10-15 vol.%), of paraffinic bio-hydrocarbons originating from the NEXBTL process.

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.
