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 finds particulates from auxiliary vehicle heaters can be up to 1000 times higher than from idling gasoline engines

Green Car Congress

Researchers from Tampere University and the University of Eastern Finland have found that the particulate emissions of auxiliary heaters can be up to a thousand times higher than the particulate emissions of idling gasoline vehicles. Their open-access study is published in the journal Atmosphere. Karjalainen et al.

Neste Oil’s renewable diesel used to generate elecricity at two events in Finland

Green Car Congress

Neste Oil’s NEXBTL renewable diesel was used to generate electricity at two major events in Finland this summer: the Flow Festival in Helsinki and the Neste Oil Rally Helsinki Battle street circuit race. Using the fuel resulted in a 22 ton reduction in emissions, equivalent in emission terms to nearly three round-the-world flights.

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

Green Car Congress

Replacing fossil fuels with Neste’s renewable fuels reduced global climate emissions altogether by a 8.3 The emission reduction is calculated by comparing the life cycle greenhouse gas emissions of the renewable fuels that Neste produces in a year to the life cycle emissions of conventional European diesel.

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. of hydrocarbons) significantly.

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.
